[Elecraft] K3 AFSK TX Filter

[Don Wilhelm]

Ed,

I am not certain what you are referring to as the "AFSK TX filter".
You must enable the 2.7 or 2.8kHz filter for all DATA modes.

You can enable any filters for receive in any mode, but you cannot use 
narrow filters for transmit.

Line In gain settings are correct per recent suggestions by Joe, W4TV, and all other K3 settings are proper. When I turn off the AFSK TX filter, the K3 returns to operating normally in AFSK Data mode, with full power output.  I can leave the filter out but am wondering why it is blocking the audio? I am using MMTTY, so perhaps it is a setup issue within that program?
