Re: FYI -- One Laptop per Child (OLPC) Opportunity
by Tom Clark, K3IO 23 Jan '08

23 Jan '08

(I posted this a couple of days ago, but it was never released from amsat.org limbo. So I resend. My order for OLPC went in today -- they accept either PayPal or plastic -- Tom) Another thing I gleaned from the OLPC wiki is that it supports FORTH (start at http://wiki.laptop.org/go/Forth_Lesson_0). Karl (DJ4ZC) designed Phase-3A back in the late 1970's and the onboard computer (IHU) used the computer language that Karl wrote called IPS (Interpreter for Process Structures) based on FORTH, but with German syntax and multi-tasking real-time support. Several of us (W0PN, W1HDX, ZL1WN, DB2OS & I) ported the German "dialect" of IPS into English and the "Gerglish" IPS has served as the basis for running all the Phase-3 IHUs up thru AO-40 (thanks to the efforts of W4SM and G3RUH). IPS is also planned for P3-E (N4HY already has it running on the new IHU) and probably P5. As another possible AMSAT/OLPC synergy, I can easily envision the OLPC Forth kernel being adapted to real-time control tasks with the addition of Karl's "chain". Although it is really modest compared to the normal laptop, Nick Negroponte and his team has really come up with a platform that has amazing possibilities! Meanwhile, ASUS has introduced their commercial Linux-based "Eee" miniature notebook that is already available ($399 from Amazon <http://www.google.com/pagead/iclk?sa=l&ai=BuJiyAGg3R9XlK4iaeuyDjLIMqprePM7t…>) -- Just Google ASUS Eee <http://www.google.com/search?q=Asus+Eee&sourceid=navclient-ff&ie=UTF-8&rlz=…> or see the Eee wiki entry <http://en.wikipedia.org/wiki/ASUS_Eee_PC#Storage> for details. 73, Tom

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.

Re: [eu-amsat] Satellite DX

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

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

I want to make a small donation to AMSAT-NA (specifically for satellites which would accessible on a world-wide basis). But, alas, i could only information about membership and the "President's Club" on-line. Did i miss something?? It seems like it might be a missed opportunity not to have information on-line about making a one-time-only donation. -- KD6PAG (Networking Old-Timer, Satellite QRPer)

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? Could be someone who open one can confirm if there is enough clearance to avoid drilling through the gear/motor system? Thank's for all your advices and for all the private one too.

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?? To: "Amsat-Bb" <amsat-bb(a)amsat.org> Message-ID: <HLENIILIDNGDDDJIDEMFGEMGENAA.stargatesg1(a)verizon.net> Content-Type: text/plain; charset=iso-8859-1 Hi all, I am installing 20' of Rohn 45 with a flat top from Normsfab and a Yaesu GS-065 thrust bearing. 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
