Tnx , base band fm ? ,
Its difficult to identify Tx/Rx that will handle modes with b/w over the standard ssb 3Khz
I think only Flex radio offers 25 KHz , linear translation ?
VARA ofdm , 9.6 , runs to about 17K bps in a 5 Khz b/w , though not suited to ''ssb''
as has no 'afc' being designed for FM ,
