I was told that if you wanted to swap out your transmitter crystal that you had to be a licensed class whatever radio person. I was further told that a radio needs to be tuned and checked before its safe for use and AMA will not cover radio setups where the crystal has been changed out. >From my backround: A crystal is a crystal is a crystal.... what they say on the case is what they are, and I believe that any transmitter can have any channel thats available for that frequency. AS long as I replace the crystals with the appropriate air/ground freq and on the same 2 channels, I believe that all should be ok. Am I on drugs or is the other person that told me what I said above? Tim RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
