One other important thing to remember about SO-50. Unlike AO-51 and AO-27, it
does not transmit a carrier. You won't hear any noise unless someone is
transmitting. You can't just wave your antenna around and peak for maximum on
a carrier. So unless you are running full duplex and can hear yo

Use a tracking program to help explain this. The altitude/height for SO-59

Have you used SO-50 before? It's not always easy to hear, even with large

Hi Peter,
Single channel FM transponders work best when there aren't many users. As

Some passes over the US can approach that level of futility. I don't

Biggest problem here is people can't hear the bird and then keep

Hi Peter,
"Easy Sats" is a misnomer, the FM satellites are only straightforward to
operate through as long as there are no more than four or five satellite

I'll add just a bit...
There are something like 8 different voltage settings/thresholds that
