Re: [TenTec] O2 output level with PSK aux

["Bob McGraw - K4TAX" <RMcGraw@Blomand.net>]

I'd check to see that the Line Gain on the radio is set correct.  If Line 
Gain is 100% and Navigator is maxed out, then yes there is a problem.  I'd 
try the direct connection method in an effort to isolate the problem.
