[Elecraft] K3 AFSK TX Filter

[Ed G]

After switching on the AFSK TX filter in the CONFIG menu, I find that the filter essentially blocks all the soundcard audio from being transmitted by the K3, so that I have no output with the filter switched on. 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?
