Re: [wsjt-devel] high sensitivity of decoder vs TRX AGC handling

[Joe T. <jo...@pr...>]

Hi Igor and Steve,

Perhaps it's worth mentioning that our advice for all WSJT-related 
programs has always been to disable the receiver AGC (if possible) and 
turn the RF gain control well down, thereby minimizing AGC action.  If 
you do this and follow instructions in the User Guide about setting the 
signal level coming into the sound card (or equivalent device), there's 
plenty of dynamic-range "headroom" still available for nearly all 
situations.

The decoders know how to handle widely different signal levels, and they 
appreciate having a reliably constant baseline noise level during an Rx 
sequence.
