I've been a "member" of AMRRON for a number of years...there used to be an HF (80 or 40 meters depending on time of year) net on Sunday nights with net control coming out of Georgia. They also do digital nets which I have monitored but never actively participated in. Propagation for the 80/40 SSB nets was not so good though maybe it has or will get better with sunspots finally climbing.I just spent the last three hours reading the AMRRON site..
