I'm just getting into satellite operations as a hobby. I've used the commercial satellites all through my broadcast career, but as a hobby, this is way more fun.

I've read about the one ham satellite over Africa. I wonder if there plans for one over North America.

I have to say using a 10 watt HT (no dual receive while transmitting) into a dual band beam (3 elements for 144mhz and 5 elements for 440mhz) all while portable is a challenge. I have been able to sort of make some kind of contact on two other birds, and ISS Sunday afternoon when it was as crowded. Hearing the quick key ups, hetrodines and even the occasional idiot that is heard whistling reminds me of CB radio in some ways.

The gentleman's ways and patient operators are becoming a long lost art.

For a newbie here, what portable radio do you all recommend? 
For permanent setups, what is recommended?

I don't see myself standing on my deck in the middle of a central NY winter and snow storm while trying to catch the satellites. :-D

AO-51 did it (two simultaneous FM xmitters)—but hardly a cubesat!!

Hello Ray

Nice idea.  channelized receive is fairly easy without excess power consumption. - single downconverter with multiple IF's or SDR equivalent.
The main issue is on transmit where you need to share the limited 'DC power' between multiple transmitters.
Probably possible to do 2 x transmitters on a 2U and 3 x transmitters on a 3U.  Some fancy final amplifier running a high efficiency mode like class D or E shouldn't hurt the power budget too much

Behavior mod on the part of veteran FM ops doesn’t seem to be in the cards. So what about this? Suppose the next gen FM birds were channelized? That would divide the number of ops per pass. Thoughts?
