Erik,
Thanks!! Obviously my info on the smoker was incorrect to start, now I can proceed to put in an inline switch, be it mechanical or electronic if I swap in a Rx with more than 6 channels. Appreciate the TG board info, just have to work through the channels (guessing it's 5) and hopefully finding the unusual range Taigen uses. BTW, the other forum (UK) thread of using a momentary switch turned out to be a bust, the owner was using a Clark board even though it wasn't mentioned in the thread.
