Default Changing Tx Crystals

Hi there,
I recently bought a Futaba 6EXA Tx and don't have a crystal for it. I know it is tuned to channel 52, but I was trying to get advice on which channel crystals I can use in it without having to send it back to Futaba to be retuned. I believe you can step 1 or 2 channels either side of the tuned one without having too many problems, but i am looking for advice.

BTW - after reading up, i am aware that it is now technically illegal to change your own Tx crystals, but since I don't have one....!

Anyone who can give advice will be appreciated!

I'm glad to see you've done some research, and acknowledge the legality of changing the Tx crystal yourself.

I would recommend, since you know it was previously on channel 52, you get a replacement on the same channel.

IF you insist on changing to another channel, I recommend you not alter it by more than 2 channels in either direction. The further you move away from the tuned frequency, the more inefficient the RF circuit can become, resulting in reduced range, and increased likelihood of spurious transmissions on neighboring frequencies.

At the risk of causing interference to others, I wouldn't change it at all. Not worth the risk.
