Nevermind, I got to thinking about it and remembered the little thermistor PC board...
Besides, if I installed the OCXO and calibrated the K2 with it on, It would be out of cal when I turned it off for portable use...
I'll still add it to the TS-450S.

Has anyone tried this thing out on a K2?

I'm getting one to put on my TS-450S and would like to add one to my K2. I will add a switch to turn it off during portable battery ops to help reduce current draw.
