I have been told by people here on RCU that changing the channel on your transmitter by simply changing crystals is illegal.
I have been told by 3 different hobby shops as well as numerous people in my club that it is not.
What is the truth and what FCC regulation states this?
Note: this started when I was in search for a crystal for a reciever I had and couldn't find one localy on my channel, the hobby shop owner offered to sell me a set on a different channel and said I could change both (I didn't buy the set but I did ask around)
