I don't have a solution for wideband transmit (since I don't own a K3)
but there is a simple fix: Run split. That way, the software will keep
the transmit close to 1500 Hz by offsetting the QRG automatically. You

I am considering purchase of a K3 (I own a K2). One application is the new
mixed JT65-JT9 HF mode. Possible accessories are:

-KTCXO3-1 TCXO (0.1 ppm typ) High Stability Ref. Osc. (to provide
