Performance of IC-471?
by jonny 290 01 Dec '07

01 Dec '07

Hi list, I'm still working hard at my station and saving pennies. I caught an SO-50 pass the other day (though there was terrible howling signal the whole time and I couldn't copy any voice) and I'm getting ready to mast mount my 70cm preamp. I'm currently shopping for a competent 70cm all-mode, as I believe my Icom 208H and PCR100s are just not sensitive or selective enough to do the job. The reason I'm drawn to the 471 are its single band construction with robust filtering, I already have a mint 271a and think the 471 would match well, and the through-hole construction means that I have a shot at preserving my investment via future repairs, barring any blown out-of-production ICs of course. Can anybody comment as to the suitability and/or performance of the ol' 471 on satellite? I imagine it's pretty decent, possibly great with a proper alignment/tuneup. I've read things about people modding the front end of 251/451's which is just one generation prior, and I am somewhat familiar with the 271 front end so I imagine I can play around with some silicon swaps on the front end to boost the performance if it's needed later (which I doubt with a good radio and a mast-mount preamp). Down the road after I get a good job I want to set up a 275/475 station but of course you all know the price tag on those beauties. I figure a 271/471 pair will keep me happy for as many years as it takes to find my '75 "twins". 73, hope to get TRX on the birds soon, and I appreciate any insight. Matt KC4YLV

hamfest/demo tomorrow (1 December)
by Patrick STODDARD (WD9EWK/VA7EWK) 30 Nov '07

30 Nov '07

Hi! I will be part of the AMSAT table at the Superstition Amateur Radio Club's hamfest in Mesa, Arizona, tomorrow morning. The hamfest is at Mesa Community College, on Dobson Road between Southern Avenue and the US-60 freeway (exit 177). The club has a web page with hamfest info at: http://wb7tjd.org/hamfest/ I will be doing AO-51 demonstrations during the 1515 and 1649 UTC passes from the hamfest as WD9EWK, weather permitting. It is currently (Friday at 2020 UTC) raining here, and there is a chance for rain tomorrow morning. Unless the hamfest site turns into a swamp and/or there is lightning in the sky tomorrow morning, I hope to be on for both of those passes. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Speaking of satellite DX, I don't know if I've seen a messge about this or not. There is a group of folks down at XF4 Revilla Gigedo for at least a week now. XF4YW (XE2YW) has been on the FM birds from time to time. They will be there for several more days. That would be grid DK48 off the west coast of Mexico. 73, John K6YK

Re: Satellite Rigs, whats available
by Reicher, James 30 Nov '07

30 Nov '07

I'd recommend the Yaesu FT-847 over the Icom for these reasons: 1. The 847 has 160M thru 70cm in one box. This means that when AO7 comes up in mode A, you don't have to use a separate rig for the 10M downlink. You'll have all the other bands as well, 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, & 6 meters, as well as 2 meters and 70cm 2. The 847, which is out of production, can be had for much less money than an IC910. I got mine for about $850. I typically see 910's selling used, without the 1.2GHz option, for about $1,000. 3. You can more easily find and install a different mike on an 847, since they don't require a special type of mike. 4. The IC910s I've dealt with tend to develop a situation where the displayed frequency does not match the actual frequency. 2 meters is usually about 3 KHz off while 70cm gets about 9 KHz off. This can get nasty to use for someone who's not familiar with the rig. 5. CAT control of the rig is as simple as running a null-modem cable from the back of the rig to a serial port on your computer. The 910H requires a CTV or whatever they call it to interface to your computer. 6. While it doesn't have a 1.2GHz option, you can still use a transverter, which tends to be much less expensive than the Icom 1.2GHz optional unit. 7. It is also packet-ready, as well as all the other digital modes. 8. DSP filtering is built-in and comes standard. 9. Less menu driven than the Icom unit. In short, the 847 is more versatile, easier to interface with the rest of your station, and less expensive than the Icom. 73 de W0HV, Jim in Raymore, MO (ex-N8AU) Light travels faster than sound...

After borrowing a 910 for Field Day one year, I immediately went out and bought my own. I didn't even look at anything else, and I love it. Sensitive RX, plenty of TX power when needed, 1.2 GHz with the optional UX-910, easy to interface to the computer, 9600 packet-ready, and great for terrestrial work as well.

I have also heard it is questionable here in the USA. While in mode A (AO7) I have made several attempts to shake loose a JA or some northern UK gent where I have a very short window at times, even a piece of Europe for some footprint streaching fun. In the days of RS15 I was able to do this fairly regularly and had many sub 4 degree QSO's to the other side of the footprint. It takes good and quick operation and a competent guy at the other end. My opinion is," if this were easy, everyone would be doing it". Generally speaking we all love a challange, at least that's what keeps my passion for amateur radio alive. I have a fantastic mentor in Joe K0VTY as well a Clair VE3NPC both of whom have forgot more that I can ever learn. There's Central and northern South america of which I have hever hear a peep out of. I had a new aquantnce in the shack yesterday who was considering satellites. AO7 (mode A) came up through the mid west and I had a nice chat with Joe K3SZH ( who I think probably owes the bird hihi). This visitor just lite up , like the perverbial bug latched on. Can we get a front page blurb in QST on the assets of AO7? This is what got me going back in the days of RS10 and 12/13. When I'm on the HF bands at times I will "steer" the converation to satellies and attempt to simplify this "complex" mode that many believe it is. It is incumbenton all of us to "push" this fantastic method. 73 Bob W7LRD Seattle -------------- Original message -------------- From: John Hackett <archie.hackett(a)hotmail.com> > > Gents, > > I suggest each and every one of us sends the relavant mail to every national > society requesting it be published in their magazine/newsletter to attempt to > generate satellite interest in the countries where there is coverage but no > operation. > > There are several countries where a potential newcomer could "rake-in" the > satellite certificates quicker than you can say "AO-7 is a damned good satellite > when it's used properly". > > Again, I've batted this over to the States in case they suffer from the same > kind of inactivity in some of the states. > > Let's educate! a few new operators ... not blind 'em with science. > > 73 John. > > To: eu-amsat(a)yahoogroups.com > From: sv1bsx(a)yahoo.gr > Date: Fri, 30 Nov 2007 12:30:24 +0200 > Subject: Re: [eu-amsat] Satellite DX > > > > > > > > > > > > > > > > > > > > > > > > Good morning John & Group, > > you have absolutely right about DXing and AO-7.

Gents, I suggest each and every one of us sends the relavant mail to every national society requesting it be published in their magazine/newsletter to attempt to generate satellite interest in the countries where there is coverage but no operation. There are several countries where a potential newcomer could "rake-in" the satellite certificates quicker than you can say "AO-7 is a damned good satellite when it's used properly". Again, I've batted this over to the States in case they suffer from the same kind of inactivity in some of the states.

AO-7 Report.
by John Hackett 30 Nov '07

30 Nov '07

I wonder how many people make the mistake of thinking AO-7 is not transmitting (when it is) but the receiving equipment isn't adequate. An illustration ... on orbit 51203 at 09:32 this morning, 30-11-07 at the start of the orbit I heard nothing at all ... absolutely nothing! from AO-7. However, switching the polarisation of my aerials to vertical (from horizontal) resulted in a received signal of S3 ... and as the orbit progressed, the signal strength incread and the polarisation changed another two times on that particular orbit. Remember !!! ... the propagation to all intents and purposes is different at various QTH's ... so the result at one QTH - (for instance, signal report) - is highly likely to be quite different at another QTH. I would advise using your EARS !!! as a reference because meters are a complete waste of time in this particular situation/application. I would thoroughly recommend switchable polarisation for LEO's. It doesn't have to be commercial and expensive. Mine doesn't even use coaxial relays - and it's built into an aluminium lunchbox ... don't laugh!, they're cheap and RF tight. There's a full explanation on OBSERVATIONS ... (http://www.observations.biz) of why I don't bother with circular polarisation on LEO satellites. 73 John. <la2qaa(a)amsat.org>

Re: Terrestrial repeater interference to AO-27

What I've been hearing on AO-27 sounds like simplex chatter. No squelch tail, etc. Unless we are hearing the input side of a repeater (the users).

Symbian prediction software
by John Hackett 30 Nov '07

30 Nov '07

To whom it may concern, A portable satellite station can be as small and simple as a dual-mode handheld plus a 3/4 wave whip - (AO-51). It isn't always convenient to lug a laptop around but almost everybody carries a mobile phone in their pocket. Pass prediction programs are available for Windows mobile and certain PDA devices but none - (that I can assertain) - for the Symbian series 60 operating system ... of which there are a*LOT*. Now, if you happen to be a"wapper" - (pun intentional) - you can get online predictions from the internet - but it's an inconvenient and "finnicky" way of doing things. Is there anyone out there capabable of writing a pass prediction program for the Symbian series 60 mobile phone operating system?. (NB - not everybody has the "latest" phone, that's why the Series 60 would be the best option for a Symbian system). The program doesn't need to have fancy graphics and logos, those are just a waste of space - (again, pun intentional) - a simple prediction table would suffice - showing date, time azimuth, elevation and range. The other criteria are not necessary when you're operating portable. I did suggest this to Emily N1DID a couple of year ago but nothing came of it. If anyone is capable - (and willing) - to write such a program I would be *MOST* interested. Surely it's cheaper to write a Symbian program than to buy a new phone that uses existing software ... like the Predict program on Windows mobile ?. Anyone willing to take up the challenge? ... (to save me purchasing a new phone). 73 John. <la2qaa(a)amsat.org>

Satellite DX
by John Hackett 30 Nov '07

30 Nov '07

Stop whinging! ... No DX you say ... have a look at the AO-7 orbit 51201 on Friday the 30th of November 2007 from 05:55 to 06:00. This orbit covered more sixty !!! entities (DXCC countries) including northeast China, Mongolia, northern India, Pakistan, Afghanistan, all 18 of the earlier Soviet republics, the entire European continent, the entire Middle East and most of the central and north African countries. No DX? ... Rubbish !!!. I battet this over to the Amsat-bb so our American friends can see what "can" be worked from Europe. I'm sure certain orbits would allow most of the states and even parts of central America on some orbit (?) ... I'm just too bone-idle to check it out. 73 John. <la2qaa(a)amsat.org>

Terrestrial repeater interference to AO-27
by George Henry 30 Nov '07

30 Nov '07

Has anyone heard that rogue repeater thru AO-27 recently? I received a phone call from Riley this afternoon, following up on my complaint about the repeater, and he wanted to know if it was still on the air. It is located too far from my home QTH to hear directly, and my satellite antennas are down at the moment. The one time I *did* hear it on the ground (early October), I was out mobile and much closer to it than when I am at home, but I haven't been up that way (northern suburbs of Chicago) for quite a while.

Just worked AO51 with my new Arrow
by Ed Tump 30 Nov '07

30 Nov '07

Folks, I just got my Arrow sat antenna this afternoon and put it together. Very nice product and easy to assemble. I mounted it on a tripod and checked Orbitron. With the Packer game coming up I thought I would just leave it in the den where I put it together. I thought hey, tomorrow I can try it out. But Orbitron told me that the pass for AO-51 was coming over soon. I thought this thing will never work inside and in the den. But that Arrow sure did work. I was so excited and happy I did not even hook up the tape recorder. So I did make my second satellite contact, the first with AO-51, and the first with my Arrow. I believe I made contact with grid FN42. Could not remember call sign. If anyone heard any of the details I would love to know. Thanks! 73, Ed KC9GWK Grid EN52 AmSat Member

How to receive OSCAR telemetry and setup APRS system
by Hamradio .9m 28 Nov '07

28 Nov '07

Dear all, I've been struggling with packet satellite since day one and I have two questions pertaining my Amateur Satellite Ground Station. 1. I'm new to MixW and very interested to know more about MixW configuration to receive Packet Satellite telemetry specifics for OSCAR. I have bought one complete package which included MixW software, RigExpert plus and interface cable. Unfortunately, till today I can't even decode any OSCAR telemetry either by using RigExpert or TNC. 2. My next question is how to operate my station as APRS? I'm be able to receive somthing from ARISS but the signal is not digipeated. The data as follow; > 9W2NRL/ISS>CQ>UI,C,F0: > HELLO FROM 9W2NRL > RS0ISS-4/SGATE>CQ>UI,R,F0 (1199 baud): > >ARISS - International Space Station (BBS/APRS on) How do I verify the packet is really transmitted on air? My station is equipped with X-Yagi Antenna, UHF Preamp, IC-921, FT-817 and KAM-XL. In the software part, I used GSC and WxTrack for tracking and MixW. A million thanks for your suggestion and guidance. -- 73 Nuril 9W2NRL

LUSAT-OSCAR 19 beacon
by Rob Hardenberg PE1ITR 28 Nov '07

28 Nov '07

Hello, Today I was monitoring the LO-19 cw beacon on 437.125 and noticed that there is always a small signal present between the cw telemetry blocks. The beacon transmit about 750mW. The small signal is about 30db down, so I guess it must be around 1mW. Does anybody have some more info (power?) about this unsupressed carrier signal? 73 Rob PE1ITR

Problems Reading ANS Bulletins
by Clive Wallis 28 Nov '07

28 Nov '07

Hi, Some time ago there was a discussion about formatting of ANS buttetins from Lee KU4OS. I'm finding it impossible to read some of these bulletins. Four recent ones are 245, 266,308, 329. I think that these may have been sent as MIME encoded attachments, instead of being sent in plain text. Here is a bit of what my text based mail reader sees - QU1TQVQgTkVXUyBTRVJWSUNFCkFOUy0zMjkKCkFOUyBpcyBhIGZyZWUsIHdlZWtseSwgbmV3cyBhbmQgaW5mb3JtYXRpb24gc2VydmljZSBvZiBBTVNBVCBOb3J0aCBBbWVyaWNhLCAKVGhlIFJhZGlvIEFtYXRldXIgU2F0ZWxsaXRlIENvcnBvcmF0aW9uLiBBTlMgcmVwb3J0cyBvbiB0aGUgYWN0XZpdGllcyBvZiBhCndvcmxkd2lkZSBncm91cCBvZiBBbWF0ZXVyIFJhZGlvIG9wZXJhdG9ycyB3a Could these bulletins be resent to ANS as plain text? Alternatively, are they available for download anywhere. I couldn't find the complete bulletins on the Amsat Website, only individual items of news. The archive didn't include any for 2007. Any help would be appreciated. 73 Clive G3CWV Hitchin, North Hertfordshire, UK.

Re: Weather Effect
by David Donaldson 28 Nov '07

28 Nov '07

John What you want to look for is the propagation effects of weather on the frequencies you are using on the satellite. ARRL has some info on its site for 2 meter and UHF. There are other sites that focus on microwave freqs such as 1.2 and 2.4 Ghz. As you found googling "sats and wx" are going to bring up sites related to geostationary sats. The weather effects will be the same between sats and terrestial use. It is possible to have weather caused refraction on your up link or downlink causing the signal strength to be have higher loss then normal line of sight. Hope my ramblings help.

ANDE Re-Entry Campaign
by Robert Bruninga 27 Nov '07

27 Nov '07

ANDE Re-Entry Campaign: The ANDE-MAA satellite (Nav Oscar - 61) will de-orbit in the next few weeks but is fully operational. We encourage activity, because while it is in use (2m packet up/down), then it is awake and sending telemetry. We want to capture the most telemetry to see if we can catch the thermal changes as re-entry approaches. Who can capture the last telemetry frame? The most important telemetry is that which is fed live by IGate into the APRS-IS system. Because that is automatically logged and time stamped. You can verify your data got in by looking at the http://pcsat.aprs.org web page after each pass. If you manually capture any packets, Please take special care to accurately LOG the TIME of any packets received especially in the final day prior to re-entry. See the contest page below for how to submit entries: Here is the ANDE Operations web page. It has links to live telemetry too: http://www.ew.usna.edu/~bruninga/ande-ops.html And this one is the CONTEST for data collection and operations sponsored by PA3GUO and DK3WN: http://www.ande-deorbit.com Any APRS station that is also on the internet can contribute telemetry by simply QSY'ing their normal APRS rig receiver to 145.825 on that final day. If you do not normally run APRS or an IGate, then you can simply download ALOGGER.EXE which is a full up IGate designed just for satelite gating without having to learn APRS. See Bill's web page: http://www.billdiaz.dynip.com/ASatLogger.htm ANDE is coming over the northern latitudes in the afternoons and evenings local sun time, but this pattern moves earlier by 14 minutes per day.

AO-7 UHF beacon received!
by Auke de Jong, VE6PWN 27 Nov '07

27 Nov '07

I haven't seen anyone ever say that they heard the beacon on 435.1 lately, so I thought I'd give it a try... I read somewhere that this beacon should be active while the satellite is in mode-a. a quick check of the ao-7 log site showed that the most recent contacts via her were on mode-b as of about 2am UTC, and knowing that her 24 hour timer is working deadly-acurate given continuous sunlight, I knew that by this time it should be in mode-A. I didn't hear anyone on the downlink in mode-a, but I decided to tune for the uhf beacon anyway, and after very faintly hearing something before it was overhead, i finally managed to latch-on as she fell to the horizon in the north. By this time my 7 el beam antenna was blinded by my house, so I changed to the horiz omni 0dB antenna, and then observed, for a few minutes, the doppler-shift-curve of a definite beacon from space. I have taken a screen-capture showing all the pertinent data, and the signal itself on the spectrum display! I think that it's a good thing I hooked up my pre-amp otherwise i might have missed it! after the screen-cap was taken, I observed the signal to "level-off" and then fade-out exactly as predicted LOS via my Orbitron program. Maybe next time I'll be able to point my better antenna at it, and hear what information the beacon might be sending! I read online that it is not a CW message like the VHF one, but rather an FSK modulated one... It's also known to have suffered low output on this beacon intermittently, or perhaps permanently. In that case, I might need a whole lot more antenna just to get a good copy anyway! someone else might be able to do a better job than I with this in mind... I'll post a link to the image which I'll host on my local provider's gratuitous server... it might not live long there however, since I might need the space for something else in the future, so I encourage those interested to save a copy of it on your own computers for later reference. http://members.shaw.ca/sparkycivic/HAM/ao-7%20uhf%20beacon.JPG enjoy...

Mental Illness - Or Just Too Much Fun?
by Clint Bradford 27 Nov '07

27 Nov '07

A crummy pass of AO-51 was going to occur in a few minutes for me in DM-13, Riverside, CA. Only 31 degrees of elevation for a couple of minutes, PocketSat told me. And me with only HTs set up to work it. "Whaddaya think, Karen?" - I asked my (most patient woman on the planet) wife. "Well, go ahead and try it," she replied. I wasn't sure if she just wanted me out of the house while she's working on her computer or not. So I went out back, petted the horse and donkey, and sat down on a resin patio chair... And worked three countries at 2.5W on a handheld: friendly guys in Mexico, an Arizona regular, and two gentlemen in Canada. I'm still grinning. What a magnificent hobby. At least this time I didn't disturb my neighbors with, "KAREN - GET OUT HERE!!!" this time. What a thrill. Spread the word of AMSAT to all. Clint Bradford, K6LCS / KAF3359 909-241-7666

My model a Yaesu G-550 looks like the same as the Kenpro KR-500 and does not seems to have any drainage hole in the casing but this will have to be visually confirm. Looking at the exploded inside schematic picture of the rotor it seems that it is possible to drill a hole in the casing to drain this excess water?

Re: Mast strength??
by Greg Beat 26 Nov '07

26 Nov '07

Charles Penninger (Penninger Radio) has that "in stock" in western Chicago suburbs (15 miles west of my QTH) You likely also have a local aluminum tubing supplier / distributor in your area -- without having to pay for the shipping charges. 1/8" wall is very nice -- and surprising lightweight for its strength. At the 2 inch diameter size you can use either 1/8" or 1/4" wall http://www.penninger.com/prod05.htm Greg w9gb Date: Thu, 22 Nov 2007 14:13:57 -0500 From: "Stargate" <stargatesg1(a)verizon.net> Subject: [amsat-bb] Mast strength??

The lower end of the tower is already figured out but I'm not sure of what strength 2" mast I need. All this short tower will be supporting is a 3-4 element 6M homebrew beam just above the bearing on the tower, as well as, the elevation portion of the Yaesu G-5500 rotor with 8' fiberglass cross mast, and M2 2MCP22, and 436CP42UG beams on each end of the cross boom. The 2MCP22 is 2.5 sq ft wind load. The 436CP42UG is 2.0 sq ft wind load. I'm not sure of the WL for the rotor and 6M beam. The mast will have to be at least 18'-20' long to give 2-3 foot inside the tower to the AZ rotor and enough sticking out the top to give 1/4 wavelength (at 2M) spacing between the satellite antenna's and the 6M beam. The satellite antenna's are close to 20' long and mount from close to the center so I need at least 10' (+1/4 wavelength) above the top of the 6M beam. I'm not an engineering type so I thought I would ask on here. What thickness and material would the mast need to be to support this. I am thinking T6061 aluminum, .25" thick wall, 2" outside diameter mast. I live in a 75mph wind zone. Any help would be much appreciated. Thanks, 73's RoD KD0XX

input about best CAT controlled duplex multi-mode satellite rigs
by Dr. Jay Garlitz 26 Nov '07

26 Nov '07

Input about best CAT controlled duplex multi-mode satellite rigs to Mike Baker, WA4HFR, at micanopymike(a)gmail.com would be appreciated: A couple of my local ham friends have finally convinced me to get geared up to work the ham birds. My interests lie more toward the higher frequencies, 2GHz and up, but I do plan to get started on 144 and 432 bands. My question: What are a couple of the very best or most recommended VHF/UHF station rigs for working the birds? Are there any VHF/UHF multi-band mobile rigs suitable for working the ham birds? I presume that suitable rigs must have software controlled doppler correction capability? Thanks-- Mike Baker WA4HFR Micanopy

rs-15 now eclipse again
by Auke de Jong, VE6PWN 26 Nov '07

26 Nov '07

It seems that by my observations that the beacon transmitter was reliable throughout this latest period of non-eclipse. I noticed that the beacon frequency was always the same(29.3512 usb), and the on/off timings seemed to indicate some state of information by slowly changing the on-duration, and keeping a steady off-duration. Now that the orbit has progressed away from the sun on the ascending node, I think it will be interesting to see if the unit will power-off and on for sunlight and behave in predictable ways or whatnot. There has been some reports from before the non-eclipse period started, where the same beacon signal was heard on a different frequency, but this was before i started listening. If anyone notices interesting behaviour such as different beacon frequencies of messages, or if they have information on how to decide what the beacon information might mean, I would be very interested to hear about it. Thank you Auke de Jong, VE6PWN DO33

First sat contact
by Ed Tump 25 Nov '07

25 Nov '07

Folks, Well I am excited to say using the approx 2035 pass of AO27, I have made my first satellite contact from EN52 to EL29 N5AFV! Thanks Allen and to all once again who have helped get me to this point. I did it from my cold lawn in Wisconsin using Orbitron, my HT Yaesu FT60, and the AL-800 antenna. I also had my old tape recorder going so I have permanent audio of that contact. Warm regards, Ed KC9GWK Grid EN52 AmSat Member

A bit OT - Workman PS-35
by Bob Stewart 25 Nov '07

25 Nov '07

A warning about buying this PSU - it doesn't ship well. I just got one of these Power Supplies, and I thought I'd let everyone know how it went. The case is very flimsy and the transformer is very heavy - not a good combination. The first one I got arrived a bit broken internally. The dealer said that it looked like a truck hit it, when he got it back. The second one I got; the transformer was loose inside, and 1 of the 4 attachment screws was detached. The regulator board was also slightly damaged. I chose to just repair it, instead of continuing to play the "shipment lottery". It seems like it will make a good PSU now that it's reassembled and repaired. But that's a lot of aggravation for a new PSU. If you can pick it up in person, then consider it. If you have to ship it, well you might want to consider something else. Bob - AE6RV

Yaesu G-550 KT-550 rotor freezing and jamming
by Luc Leblanc 25 Nov '07

25 Nov '07

This question is intended for part of the world who have below freezing point WX. I have an elevation rotor the Yeasu G-550 installed up side down but who work 2 winters seasons here. This year he just start to freeze and he stuck under minus 0C temperature? Just before having to dismantle about 6 beams on the boom did anyone experienced this problem? As it seems this rotor has no draining holes i just think to add one to let the excess humidity to get out of the casing hoping the next above freezing point period will melt the ice build-up allowing water to drain out of the rotor casing. Thank's for your input before i start drilling in the case...:) "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

This question is right up my alley. I used to work for Lucent Technologies. I built many Central Offices, and upgraded quite a few more. When attaching copper to copper, or any other metal for that matter, we used to use a product called NO-OX-ID. It is slightly toxic so if you do get it, don't ingest it...etc. But it is the preferred metal prep in a CO environment. I used it when I built my eggbeaters.

I use a secondhand FT-51R through an Arrow with in-built duplexer and a high power battery bought separately, to give a nominal 5W. I tape-record all qso's onto cassette. However I'm sure I have some loss through the in-built diplexer. Works fine, I prefer elevations above 40 degrees to tx, although I can hear down to my horizon - you can see some of my operations from my website http://www.andythomas.eu and follow the link on the left.

Looks like their command station refit has finished and they are operational again. Apparently it's possible to e-mail them and get a schedule for the beacon. 73 David Mission Operations Log Summaries 10/16/07 - The ops team was finally able to get back into the SRI station although some work remains to be done (like re-installing the UHF feed). Two contacts were run today, lde by the fearless I. Mas. The beacon was re-enabled and verified, and state of health data was downloaded given the extended time over the past 2 months during which no operations were run. Satellite bus health is nominal, and the previously observed payload temperature control anomaly continues (again, we note that the anomaly is for a function that is no longer needed to support the mission). A new ops trainees participated in the contacts and showed off by hand-tracking the beacon with a hand-held antenna and transceiver (nice job Jose!). Post-pass logging was initiated via the internet from Munich! We currently plan to run the next set of contacts next week, and the ops team is working with the engineering team to establish a set of end-of-life test objectives. CK Mid-August through Mid-October Summary - The SRI station is unavailable during this time for maintenance, retrofit, and other test operations. The beacon will be shut off during this period. CK Early August 2007 Ops Summary - The ops team is training several new mission controllers for educational purposes as well as initial training for the team's next satellite, PharmaSat. The team is retrieving routine health data and is also conducting power stress tests (which occasionally require the beacon to be turned off) in order to assess the power generation capabilities of the system. The satellite bus health is nominal. Payload health is good with the exception of the payload temperature control process (temp is below setpoint, the control loop is activated, but a much lower than nominal heater current draw exists); we will monitor this system and develop a plan to evaluate the heater FET and/or other possible root causes. No operations during the week of Aug 12 given the attendance of most of the team at the AIAA Conference on Small Satellites (which includes presentation of several GeneSat-1 related papers). CK July 2007 Ops Summary - Only limited operations conducted in July due to routine maintenance with the SRI station and its use to support other studies. Satellite beacon off. CK

Re: Let It Snow

Hello Bob, and Everybody else today... I agree, but I'll go one step farther. Now that the foliage is gone here in Upstate New York, it is pretty amazing (yet again) how low on a pass I can hear. It reminds me of the US Government's Radio Manuals that you are supposed to learn from while serving in the Military. I recall a manual pertaining to VHF that compared types of foliage, and the expected outcome if you transmitted in that vicinity.( The phrase, "Jungle-No good" comes to mind) Anyway...now that the leaves are gone it's pretty amazing how much better I can hear.

Alpha-ish release of satcontroller for windows
by scott wilson 23 Nov '07

23 Nov '07

I released an updated version of my satcontroller software. If anyone's taking advantage of the long weekend, give it a shot and let me know if you have any feedback. Biggest changes are a map mode and removing the dependencies on everything except .NET 2.0. Sorry that it still only supports ICOM CI-V and Yaesu rotators. Next on my list will be getting the FT-817 working. I'd love to hear if anyone's successful with the 'one true' tuning method on a linear bird. In theory it works great :) - In practice, tho, my antenna performance isn't up to it. http://code.google.com/p/satcontroller/ Regards, Scott Wilson NW2S

We got our first snow of the season last night. I've got about 2" of snow on the roof blocking the omnis, but I have a good copy on AO-27 down below 20 degrees. I'm kind of surprised that I can hear as well this. I had kinda figured that the first snow would be the end of using the attic antennas. Bob - AE6RV

A *must* read for the potential newcomer to satellites.
by John Hackett 22 Nov '07

22 Nov '07

>From OBSERVATIONS ... <http://www.observations.biz/> By LA2QAA & GM1SXX ... This observation by GM1SXX. See also ... "HOW MUCH POWER IS ENOUGH" by LA2QAA. A *must* read for potential newcomwrs to amateur satellites. .................................................................................................................................................................................................................................. “More power Egor.” - Dr Frankenstein. Here's a good question from a regular reader. > Why is it bad to use more power than absolutely necessary when >transmitting to a satellite and how does this affect the battery >capacity of the satellite? There are two answers to this one. 1) With an FM bird, power is not an issue. FM is a continuous duty mode. When a signal is present on the transponder, no matter whether you are whispering or yelling, the power consumed is, or should be, exactly the same. FM transponders operate in Class C. With Class C amplifiers, when a signal is present, the transponder consumes what would be considered a 'normal' amount of power. With no signal present, the power amplifier (PA) consumes virtually no power, and since the PA is *the* major power consumer on a satellite, this is good. Only the receiver and IF strip are active with no signal present. Power consumed from the battery therefore depends primarily on how much time the transponder is active for during each orbit. OK, I've neglected the other power consumers on the bird such as the command system etc, but these are NOT affected by the behaviour of users. 2A) With a LINEAR transponder bird, running excess power on the uplink is a VERY serious issue. On a LINEAR transponder, the transponder's bandwidth (typically 100Khz) is 'shared' between the all of the users users in the transponder's 'passband'. The transponder literally takes a chunk of spectrum, amplifies and re-transmits it's entire contents on a different frequency. The total transponder power available is therefore SHARED between the users. If one user runs excessive power, the automatic gain control (AGC) in the satellite's receiver reduces the overall passband gain to compensate. This reduces the strength of the downlink signal for EVERYONE. It's therefore easy to realise that if everyone ran the MINIMUM uplink power, the satellite AGC would never be operating and therefore the DOWNLINK signals (for everyone) would be strongest. This is an important point. If the power level of even ONE user is greater than the AGC range can cope with (all too common I'm afraid), the transponder 'limits' (bottoms out), and in extreme cases goes non-linear with the excessively strong signals 'FM modulating' it. In short, it consumes a great deal of power while NOT providing any useful communications. 2B) Now for the serious stuff. Linear transponders operate in Class AB. The power consumption of the transponder is roughly proportional to the strength of ALL the signals in the passband. If one signal dominates, it will use most of the available downlink power, If it's strong enough to trigger the AGC into action, this lowers the downlink power available for EVERYONE ... INCLUDING the offending station. So, with a linear bird, the amount of power consumed from the battery is heavily dependent of the strength of the strongest signal! You may be interested to hear that 5W is enough power (to a modest yagi) to work CW on Amsat Oscar7. It was certainly also the case for the sadly now defunct Russian radiosport satellites. Satellite receivers are generally VERY sensitive indeed. The limiting factor with Linear birds is the IQ of the most thoughtless user. Many users are sensible, but it only takes ONE user running excessive power into a linear transponder bird to ruin the party for all. Since the power consumption of a linear satellite bears an almost linear relationship to the total power in the passband, the use of excessive power will rapidly run down the battery. This compromises the expected lifespan of the satellite by degrading the battery components. Satellites in Low Earth Orbit have brutal demands made of their batteries. 14 orbits a day is typical for these birds, so the battery suffers 14 charge-discharge cycles each day. Try doing that to a set of Ni-Cd batteries and see how long they last! Because the operating regime is so harsh, the batteries need to be over-rated , in order to provide an acceptable battery life expectancy. Battery Charge Regulators (BCR's) also help greatly to provide an acceptable working life for amateur satellites. ---------------------------------------------------------------------------------------------- Put simply, here are some basic satellite facts FM satellites PRO's. Can be used with cheap FM equipment. CONS Encourages bad operating practices thanks to FM Capture Effect. Only supports one QSO. Linear satellites PRO's. Can support many concurrent users AND modes. CON's. Easily 'clobbered' by FM type operating practices. ----------------------------------------------------------------------------------------------- So the operating practices for linear and FM satellites are very different. Unfortunately some users don't realise this. LA2QAA & GM1SXX. 22-11-07.

AMSAT's Power Developments in the news
by Tom Clark, K3IO 22 Nov '07

22 Nov '07

Many of you have heard that Lew McFadin (W5DID), working with Steve Bible (N7HPR) and Steve's colleagues (especially Keith Curtis) at Microchip (the PIC people) have been working on a next generation power conditioning system. The basic idea is to have a power charge/discharge conditioner for each cell of the spacecraft's battery pack. This will allow the use of several different battery technologies (NiCd, NiMH, LiIon, etc) and also some of the new "super capacitors". Some of you who were at Dayton may have seen the breadboard mockup of system that Steve brought and Lew was showing. Lew was also showing some ~2000 Farad(!) 3 volt capacitors (some of us dubbed them "flux gate capacitors"). The SuperCap developments have been exploding of late. One immediate service is for regenerative braking in hybrid and electric vehicles, since the capacitors seem to be able to withstand a (virtually) infinite number of charge/discharge cycles, and then can "soak up" & discharge huge currents -- must faster than any chemical batteries can do. Batteries store watt-hours of energy, while capacitors handle large numbers of watts of power. One German light-rail system employs a total of 600 2600Farad capacitors for regenerative braking. Some US electric buses have capacitor banks with 144 18Farad capacitors that deliver 400 Amps at 360 Volts. Today I received the 11.15.07 edition of Electronic Design magazine, and there is an interesting technology review paper entitled "Get the Lowdown on UltraCapacitors" starting on page 45; the article is available online at http://electronicdesign.com/Articles/ArticleID/17465/17465.html. Starting on page 50 (the 3rd page of the online version) The AMSAT/MicroChip effort is described along with schematics (figure 6, also http://electronicdesign.com/files/29/17465/Figure_06.jpg). The closing paragraph (which doesn't mention the planed use of these concepts on Suitsat2) says: > Microchip worked with AMSAT-NA, the not-for-profit private organization that develops > amateur-radio satellites. AMSAT’s next big project, the Eagle satellite, is slated for > launch in March 2009. To make Eagle function for decades, it will have a power system > based on this work that combines solar panels, lithium-ion batteries, and ultracaps > in an integrated power system that will optimize the use of each of those components. Pretty good publicity! 73, Tom

> Can any one tell me if their is any software to decode > ande-tlm that will run on win 95. Hi Ryan, Using Hyperterminal or ASatLogger (ASatLogger is my favorite) (see http://www.billdiaz.dynip.com) you will decode strings like this: ANDE-1]BEACON,qAo,DK3WN-1:T#002,003,010,009,004,003,01000000,000 That is already a really fantastic start if you receive them ! Now if you go to Mike's website you will find a decode SW (in fact it translates these values to onboard voltages etc.) http://www.dk3wn.info/sat/afu/sat_maa.shtml Let us know if you where able to go all the way there ! Succes and see you on ANDE ! Henk, PA3GUO http://www.qsl.net/pa3guo http://www.ande-deorbit.com

> Is there any software to decode ande-tlm that > ... That I can use before ande deorbits. ANDE Telemetry is just standard APRS (KPC-3+) telemetry. And you can see anyone's telemetry from any TNC, including ANDE's live and decoded on the FINDU.COM web page. Use this special URL to see FINDU's display of ANDE telemetry: http://www.ew.usna.edu/~bruninga/andeTLM1.html This link above is on the ANDE-OPS page labeled "SIDE-A Telemetry": http://www.ew.usna.edu/~bruninga/ande-ops.html Your downlink packets can go directly to this site for immediate display along with everyone else's. Just connect your receiver to your PC and run any kind of APRS or ALOGGER I-Gate software and feed packets heard into the global APRS system. As you can see, right now the data is kinda sparse because not that many people are feeding live data. But hopefully that will improve. Bob, Wb4APR

Re: Right Angle BNC adapters

Good Afternoon, everyone. I just wanted to pass along a whole-hearted thank you to Dave WB6LLO for sending me a much better Right Angle adapter than what I had been using. And, as many members here had noted, the differences are astounding. (My old one indeed WAS one that utilized a spring rather than any real conductor.) Happy Thanksgiving everyone. This year as I am sitting down with my family in thanks of our many blessings, I will be sure to include all of my friends here at AMSAT and in the satellite community in my prayers.

Re: Amateur Satellites Anniversary
by John Marranca, Jr 21 Nov '07

I think that is an excellent idea. To have all of the remaining satellite pioneers give their stories once again to us...the new...should be top priority with the coming of the "next generation" satellites, and their users. A few nights ago, I perused some old issues of QST that I have here, and two artocles in particular were awe-inspiring. One was the first amateur two-way Moonbounce QSO, c. 1960...and the second was the Project Oscar and the Oscar 1 transmitter. Good Luck to all on this most stellar endeavour.

Amateur Satellites Anniversary
by Dave Guimont 21 Nov '07

21 Nov '07

Hello Robert, et al, Suggesting an anniversary name for amateur satellites around the world: PROJECT OSCAR ANNIVERSARY and 12 December should be the day. Project Oscar coined the name OSCAR for Orbital Satellites Carrying Amateur Radio. And the original group that built, and contracted for the launch was Project Oscar. The following has some of the history, in addition to the excellent sites you provided, should anyone be interested. I was still on active duty in the navy at that time, and did not get involved until I returned to San Diego ~1965. A short time after that, my wife, Leanore, prepared their newsletter, and still has considerable information on the history after 1965. And I am sure Harley Gabrielson could supply us with a lot of the history...He was involved from the outset.. It took us until 1975, for various reasons, and to find suitable housing to erect an antenna, and cut my teeth on AO7.... http://www.spacetoday.org/Satellites/Hamsats/HamsatsBasics.html Project Oscar members come out of the woodwork with suggestions and or information.. N1DID, (W0EEC) Emily did the news letter for a period, maybe still does, and am sure she has a wealth of info. Cliff Buttschart, K6RR, was the glue that held Project Oscar together for some time, and things seem to fall apart with his passing...I would be interested to hear from anyone on their present activity....DON'T LET ONE OF THE BIGGEST EVENTS IN HAM RADIO DIE ON THE VINE... Congratulations to you, Robert, for the inspiration. When we get going, I'm sure I can enlist my wife to do the compilation, unless others choose to do so. I don't expect this to be an AMSAT-NA project, but AMSAT-WORLDWIDE, with as many translations as possible, to REALLY UNITE again with the launch of P3E!!! And if any reader has any connection with an amateur oriented publication, ask them to help us out.. I'm available collect from any where in the world, anytime: San Diego, CA 619-275-1495 And the ARRL 10 meter contest is just before that date this year, 8 & 9 Dec...Yak it up there!!! 73, Dave wb6llo(a)amsat.org Disagree: I learn....

Radio Shack Rotator Voltage
by John Henderson 20 Nov '07

20 Nov '07

I just picked up a used Radio Shack 15-1254 Rotator only..no control box or specs. Does anyone know what the drive voltage requirements is on these rotators. I've googled without any luck. Am planning to build my own control box with a momentary switch and some LED's for direction indicators but I need some specs. Radio Shack doesn't have them. I went to RS and looked at a new one and it gives no details. Thanks in advance....73 John John Henderson N4NAB 212 Bayside Drive Cape Carteret, NC 28584 252-725-2744 <mailto:[email protected]> n4nab(a)amsat.org <http://www.amsat.org/> http://www.amsat.org/
