So if I understand correctly this soon to be option is basically constantly adjusting the frequency of the K3 to be correct.
Or in other words a constant adjustment to the reference oscillator. This could be a real nice to have, as I have been re-adjusting (zero beating to WWV) to try and tune my K3 to be spot on. The reason I have been doing this is that I was thinking I was off frequency but I think that many radio's out there are off. Thanks, now I need even more money.
