[TenTec] Corsair 2 not stable on receive, 20 meters

[Mike Bryce]

Like, Dave, I don’t know if I’d do PSK with the corsair, but that being said, the only thing that could make a change in freq is the PTO.

have you run PSK on another band? It’s possible the PTO is drifting a hair  and you’re seeing it on the computer screen, but not enough to should up on the radio’s freq display.
