I wrap a few turns of like a #20 solid insulated wire around the little jumper that goes from the PCB to the SO239 in the back of the radio, and then just put an RCA plug (or PL259) on that and plug into an inline counter. That's always worked for me in the past. That way you're not needing to tap into any RF path.

Also, whatever VFO you use, don't use the internal power supply in the VFO itself, use a small well filtered "linear" supply (transformer, voltage regulation, etc) for the +12VDC. It will make the VFO run more stable and eliminate any DC hum/ripple in the TX/RX.

Let us know how you get on.

~Cheers~
