David,

I don't have an answer for your question though well aware that bandpass filter affect on use of K3 IF for transverters.

For Rx, if you have the KBPF3 installed, it will extend beyond 14.350 but unknown if that is true for Tx.

I use 28-32 MHz as IF for my VHF/UHF transverters up thru 1296. Many are probably unaware that the K3 will receive up to 32-MHz in transverter mode. However RF output drops off severely above 30-MHz. My 50w transverter output at 146.52 (IF=30.52) is 6w due to low drive from the K3. At 146.000 output is 15w. At 145.800 35w. And 144.000-145.500 50w.

Use of my KX3-2M is for the full 144-148 MHz band, making it way more usable as a multi-mode 2m radio.

But my use of the K3+ 2m DEMI transverter is primarily for the bottom end 144-144.200. I have 2m FM radios for the rest of the band (and the KX3-2M, of course).
