Phil, I'm confused. You say that your side tone pitch is changing, but from your statement below it sounds to me as though you are talking about the received signal from the station you are working. If that is true, then the problem would not be with the K3 side tone, but with the stability of the transmitter at the other end. When this occurs after "a slight pause in the senders signal", then it would mean that the sender's transmitted frequency has changed during the pause. Many older tube type rigs exhibit this behavior for many reasons. You will hear this sort of behavior from many of the Cuban stations on the air, because they have no access to modern radio equipment (unless they are a "good Party Member").
