[Elecraft] K3 FW3.51 & RTTY

[Greg]

Hi Brian.  I wanted to test this so I have been working some rtty this 
afternoon.  I don't see any difference in the dual peak traces with AFX 
either off or on.  I tried with AFX set to BIN and also with some of the 
delay settings.  In all cases the traces looked the same and did not change 
decoding.

Do you maybe have Line Out set to = phones and maybe that is doing 
something?
