Getting radios Tuned

What can you to do to get to TX or Rx tuned up properly like you’re “supposed to?” I have or can get some free or cheap Txs for the local children’s MS summer camp, but they’re all airplane radios. There is a big wading pool, so I’d like to take all the Footies there for summer camp.

But I only have my one personal radio…

Is there a service you can use to get your radio stuff tuned?

thx

After many private discussions and emails to the manufacturers, I have to conclude that YOU CANNOT RETUNE 72 MHz TRANSMITTERS to the 75 MHz range. They are all purpose-made now, and you can’t do much at all with them. If something goes wrong, you have to buy a new transmitter.

thx
