Ao40 was not too complex. I work in the space industry, I've already have
my electronics fly to orbit (not AMSAT), it's awesome and scary all In one.
Watching it launch not too long ago was gut wrenching, the entire system is
complex but I trusted in my testing, I trusted my coworkers testing, and

That's not how I read it. In any event, AMSAT has already built far more
complex satellites; remember AO-40? (Maybe that one was *too* co

In my email of last evening about LO-78 I failed to mention one important
thing relating to it. Where to find the best TLEs. The only place
LituanicaSat-1, LO-78 showsup is in the Celestrak "Cubesats" listing. It
has never shown up in the "Amateur" listing that they publish. WA5QGD's

Is this an appropriate HT for duplex sat work? I think it is but wanted to
check with the group. I'm thinking of replacing my old boat anchor HT, but
it does do full duplex.

Here is a site that might be of interest. It gives the declination and the

Hi all!
Stupid question but one that has been bothering me. What reference does
satpc32 and Orbitron use to generate the azimuth?
Is the resulting heading true or magnetic?
Comparing the two programs, they seem to be the same.

It was Lateran last night making that previous post and so I forgot to mention
that the best and most current TLEs for Lituanicasat-1 are through Celestrak's
"Cubesat" list. It doesn't appear on the Amateur list there at all (Don't
understand why that is) and WA5QGD's distribution is 10 minutes
