I can leave the filter out but am wondering why it is blocking the audio?
The AFSK TX filter is a narrow audio filter that allows only the defined mark and space tones to pass. Check the PITCH setting in AFSK A and make sure it matches the MARK setting in MMTTY (e.g., 2125, 1275, 915Hz).

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?
