FAR circuits even has PCBs for the AMRAD one, but easy enough to perfboard it. Some other ones, incl. commercial:

I use the VK3XDK boards, one full TX/RX and the other RX only so I can use the K3 in diversity. The transverter LO is 10 MHz, which is a transverter band in the K3, so you'll get direct freq readout. Someday I'll get the new synth boards and bypass the transverter....

Can someone point me to a schematic for a transverter that can run with a K3?
I'd like to build something up to try this out this new band.
