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.

Hardline available
by w7lrd＠comcast.net 28 Nov '07

28 Nov '07

Hello Switching to LMR coax with an amp near the antenna and I have a lot of hardline I want to unload. About 125 feet (one piece) of Cablewave systems 16733-810921-001 (not sure what that number is) FLC-78-50. Also about 300 feet (about 4 pieces total) of GCC-AL-500P 1/2 inch. Pick up or I'll meet you half way if you're within 150 miles of Seattle. I don't know what this stuff is worth, will sell or trade for whatever ( I could use a vhf/ufh mobile). Also on ebay some tunable connectors for 7/8 hardline. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=110199802903&ssPage… XYL says I'm collecting too much stuff. 73 Bob W7LRD Seattle

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. Just monitor 145.825 MHz. Enjoy! Bob, WB4APR

Auto Audio Recording

Do any of the tracking programs have a audio record function. I would like to track multiple satellites, tune my ft-897, and record the audio. Right now the program that I am useing to record audio has to have the start and stop record times manually programed into it for each bird. Mike N6IMF

I finally get through the rotor casing with a 3/16 drill bit and just before i found "the drain hole" exactly where you tell Gennadi "NEVER INSTALLED THESES ROTOR WITH THE DRAIN HOLE UPWARDS..." As soon as the drill bit pass through the casing there was a fluid leakage who stay flowing in a steady jet for 10 seconds!! and dripping for another 10 seconds with the aid of a metal wire inserted in the hole. Collateral damages 1-Probably a mess inside? rust? corrosion? mildew? and so on... 2-Upper hole plugged with a metal screw plus silicone 3-Struck something when drilling pass through the casing!!! (Not too lucky with lotto ticket...) 4-Meter does not move anymore probably a wire cut or the pot has been stabbed Lets the weather return to the minus 0C again and just watch the rotor Conclusion Rotor will don't freeze in ice anymore (i hope) and i will have to rely on a visual metering system in daylight and on something else overnight. Thank's to my neighbour dog a Labrador moaning and barking after me at the end of his chain during the whole operation... Just forget my pliers and screw- driver down the tower!!! as i am not too lucky with my drilling probably the same with my pitching...JOKE ;) As we can pass in an episode of minus zero C temperature at any moment i don't take any chance and i jump on this +C swing i just remember a past winter with another rotor stuck as water fill in due to a crack in the casing not too happy to have a beam always pointing towards nowhere.

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

Re: Mast strength??

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

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

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
