Am I right in thinking the amateur sats switch comms off when not in

Hi Dominic,
It's a great question!
If the satellite has batteries that can keep the communications
payload ON, the satellite can continue to support communications
during an eclipse (what we call the time spent in darkness).
Some satellites do not have batteries, so they will support
Dominic,
Welcome! Actually, most satellites start out operating continuously. They
run on batteries when they are in the dark. Normally the batteries over
time lose capacity. Then, various techniques are implemented to conserve
power so that they can continue to operate when in darkness.
Hi Chris,
You have a great memory :)
We had hoped that with some experimenting that we could configure
IO-26 into a bent-pipe FM/SSB repeater like we did with AO-16. Thus
far, I haven't been successful. It is likely that the hardware isn't
in place to permit this. We haven't completely

Excellent Henk.
I took a quick look at Kodiak.
I estimate AOS on orbit 3 around at 5.54 UTC with LOS at 06.06 (That's 4
hr 30mins after launch)
With orbit 4 at 6hrs 9min after launch.
Reasonable??

they are the closest to your location

Thank you, Bob, for clarifying this. The original letter made mention
of several types of antennas, including 1/4wave dualband and jpole,
both of which are, in your terms below, gain omnis at 440. (Jpole
being a 1/2wave antenna, e.g.) I first wrote the letter with these
distinctions kept intact,
John,
I have worked them before. If you hear many stations being answered, thats
because there are many stations. 144.490 uplink should be used. You
didn't mention any type of antenna you are using, however, on a pass that is
below 45 degrees, you mobile should work OK-Just use the highest

Got to admit. I'm 57 years old, and I'm still as geeked watching this

I certainly hope that there will be a replay. The flight controllers are
still monitoring the flight. Apparently they are checking orbits and
bringing the booster back in. I would call it a pretty flawless flight. Now
it's up to the satellites to do well.
