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.

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? --Ed—
