[amsat-bb] D-Star ONE PHOENIX

Sat Feb 3 02:56:23 UTC 2018

Hi Frank,

I was just thinking of buying a 5100 because I don't seem to be able to
reliably get into the FM satellites with just 5W from my HT and I read the
manual and according to it the minimum tuning step is 5kHz. It would be
nice if a smaller step could be achieved through CI-V but I doubt it.
