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...

Oggetto: [amsat-bb] The story about Hayabusa..
THIS IS A MUST SEE !!!!!!
What a wonderfull story about "Hayabusa", a spacecraft that explored and
landed on an asteroid..
Listen and watch at Fullscreen !
A nice movie to show to your kids during the long winter nights....
Thank you JAXA !!
Ohhh.... I'm getting sentimental...
We are waiting for you...

Thank's again Gennadi and Dave for your inputs Eagle as landed!!! 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.
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
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
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.
To be continued...

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.

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
"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.
