[amsat-bb] Best HT for satellite operation?

Thu Mar 9 23:55:07 UTC 2017

Even the $30 Baofengs support cross-band memories for sat operations. That's how I started, but as Paul said, half-duplex on FM should not be condoned now, especially as our FM birds get more and more crowded and it becomes just an additional source of QRM. 

I've been very happy with my D72A. Packet is a nice feature to have to work ISS and NO-84.

73,
