I was advised it might help me if i got some different crystals for different channels since there are more people that run channel 58 at there field.I have seen a tx that had a crystal that you could remove and change to different channels,it was on the front panel,the guy had several different ones and matching ones for the rx,however he didn't have the rx,one more reason i didn't buy it.The crystals he had were a lot bigger than the one i have in my tx.
If i had the money i could buy a programable tx but i don't. []
