Gary picked up a very clean Gem on ebay and asked to have it converted, heres the result
Uses the standard PIC single-channel emulation encoder and a Frsky V8 module:
Where on earth did you find a V8 module?! I gave my last one to Ron a few years back, and I assumed they were all safely installed in conversions by now. For size they are still the best ones made aren't they? The DHT is larger with it's telemetry port and components on both sides of the circuit board and the new XHT modules are fractionally bigger again. That's progress for you.
