Once in a while when I am in the middle of a QSO, my channel selected in the waterfall will move off my QSO. I look at my radio it is still on the same frequency. I run fldigi with the PSK browser open. Is fldigi jumping to a stronger signal? Or is it adjusting for the distance station I am in contact with, and over adjusting the freq select in the water fall? This happens about every other third QSO, mainly with weak stations. Also debating if I am accidently hitting a key on my keyboard to cause the frequency selector in the water fall to change. Operating system: windows 7 Thanks for any insights?
