Swapping crystals between identical transmitters???
I'm quite surprised by the information I'm reading. I've got a JR783 and when I first got it it came with channel ?? (I can't remember). I've switched immediately to channel 53 that I had in my old radio. I've been flying for over a year this way and have never had a problem. Yet, if I'm reading the orginal post correctly a transmitter is tuned to a specific channel when you buy it. If that's true why do they sell transmitter cystal at all? Just for replacements?
