Re: Rigs for FM Sats including AO-51 (Echo)



I expect many of the handhelds have the same problem, as they aren't 
intended to bring up both "sides" of the rig from a single memory.  Both of 
my HTs "suffer" from this, but I do not consider it a limitation for their 
use.  FDX, yes, that is a limit.  Both memory channels, no.

I would recommend deleting that criteria.

Kenwood TH-D7 doesn't meet criterion 4.  You can only have 1 band in a 
memory channel.
