Ok. Yes Sorry was typing my phone. Yes I was talking about SSB. I have an
HF all mode, but don't have 2 meter or 70 cm on that radio. I have a couple
FM baofengs HT's. So guess I use them for SO-50. Ive been doing some
reading and thinking of getting a USB dongle. Ive been reading on the
funcube dongles, but not in my budget right not, but was looking at these
cheap dongles. Will they work for AO-73 and other satellites?
