I have seen this behavior using a non-Elecraft exciter (Kenwood) and KPA1500 amp on digital modes. In my case it was right after connecting the new radio and TX audio levels were too high, causing splattering. The freq counter in the amp wasn't happy. Lowered audio level to where there is no ALC deflection on the exciter and problem never happened again.
Just a thought but check your ALC when on WinLink. You should not see any ALC indication.

I am seeing issues with my KAT500 not holding a setting, but jumping to (and displaying) a frequency 200 - 300 KHz lower unpredictably during a Winlink Vara session. It always comes back to the correct frequency when the rig is transmitting, but has to go thru a short relay-clatter routine to get there. This is on 80, 40 and 30 meters (all I have tested so far). For example, if the dial frequency is at 7101 the tuner can't seem to decide whether to sit on 7104 or 7096. That doesn't seem to cause a problem as much as when it suddenly drops to 6874, 6864 or 6856. I am seeing similar behavior on 80m and 30m. I recently did a total reset and reloaded the firmware (v01.75). Any thoughts? Bin width?
