Airtronics Transmitter
I have an old Airtronics transmitter radio system that is out dated. From what I understand, I need to update the frequency. The 2 numbers on the transmitter are 54 and the crystal is 72.870. This transmitter is from the early 90's and I only used it once to run the engine. I am looking to get my plane up and flying. My biggest question is would it make more sense to buy a new sysytem or are there crystals I can get to update this. Thank you in advance.
