One of the XW-2 birds seems to have a steady digitial signal in the center
of the passband. Is this from the bird, or something it is hearing on the
If it is on the 435.21 to 435.23 uplink it should be nice challenge to try
to derive its position from Doppler observations, and then start searching
on the ground. Both are lots of fun and a nice ham challenge.
Again, I have not listend to these birds enough to get the big picture, so
if I am confused, ignore me.
Its just that this week is our classes annual week to tune in some
satellites and I have heard this signal multiple passes.
AO73 is now in continuous educational mode. Please expect the next mode change to take place on Thursday.
Predictions indicate that AO73 will enter continuous sunlight for a period of approx six weeks on Tuesday!
What would be nice if one location had all the files (even Amsat). A newbie like me just starting out using SatPC32 has a big learning curve. Making these available would be a big help. Is there such a place? Or someone that could send the files?TNX 73 Mike K4MIA
I was able to hear the past 2 passes of AO-92 this morning.
Per the the past couple of posts, it looks like AO-92 is using the 1.2
How can I find out when it will be using the 435 uplink freq ?
I understand why FM satellites need an PL tone on uplink (to keep out
land-mobile services, like taxi-cabs, etc), but why is a PL not required
for the linear sats utilizing the same frequencies? A linear transponder is
certainly capable of receiving/transmitting an FM signal (albeit not
successfully demodulating that signal).
This question came up at a satellite presentation I did, and I had never
thought about it. ( Moreover, will radios even transmit a PL on SSB/CW
The new FM sats have inspired me to work on the antenna project ...

I heard a mysterious Chinese satellite at 9k6 BPSK on 435,325 MHz:

Likewise I still have my 33-inch offset dish with 6 turn RHCP helix
feed with MKU LNA and two Drake converters: one unmodified with
123-MHz out and other modified for 435-MHz out. Worked very well on
AO-40 mode-US and mode-LS.

Subject: Re: [amsat-bb] S BAND USE
No immediate plans for AMSAT-NA but GOLF will give us opportunities to
play with a variety of bands over time so I won't rule it out.? Anyway,
I still have my K5GNA downconverter and BBQ dish on my array so I'm in a
reasonable position to influence a way to put them back into use if I
get a hankerin'!?? :-D
