I observed the same problem when I use any of the filters (XFIL) other than the main one OP1. The narrower filters can be slightly off frequency but you always transmit with OP1. Thus you will be slightly off frequency when you transmit at what you hear for the other parties frequency. His PSK program will use AFC to find your signal and transmit at that frequency. Thus the next time you will transmit lower because your AFC is also tracking. Cure - If you use narrow filters then SHUT OFF AFC in the PSK program (it's near impossible to get the narrower filters of the K2 within 1 Hz.)
