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....
