[Flexradio] Scratchy signal on 160

[Dudley Hurry]

Phil,

Sounds like you might be getting some RF into the FireWire or into the 
computer effecting the FW..  To prove it, you can go into a dummy load,  
but make sure that you have ferrite chokes on the FireWire,  both ends 
if you can ,  but primarily on the end by the computer..  RF in the 
digital can make the TX sound rough.  The triple shielded cable from 
Grante Digital might help also..  See if that helps.. 

73,
Dudley
