There are similar jumps in the COMM_A and COMM_B currents. Maybe this is the reason for the jumps in frequency ?
Mark, N8MH: Just read your observations about CP-6 frequency jumps. I have seen exactly the same thing for days now. I thought it was bad Kep elements :) I’ve seen it drop back in frequency toward the end of a pass, too. It is about a 600-700Hz jump, from what I’ve seen here.
Good work :)
