Weather Effect
by John Henderson 27 Nov '07

27 Nov '07

My reception on the LEO's has deteriorated over the last week. During this period we have had some rain but mostly overcast with thunderstorms within 50-60 miles. I have checked all the connections, etc on the antenna. The noise is sporadic hum and lots of QRN. I have searched for " effects of wx on amateur sats" but turned up nothing. Was hoping someone could point me to some info on wx and sats; I know it has some effect on Direct TV etc but need to get to the source of my problem. It is there with the PA on and off...

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 26 Nov '07

26 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 26 Nov '07

26 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
