Ok... sorry I'll elaborate:
1. Fly to area where JTAC is supposed to be
2. On my radio stack. There UHF AM, VHF (the digital looking one) and below that the FM radio (I assume)
3. I set this to what ever frequency is required say, 40mhz FM. And turn the dial to TK and move the frequency dial over to FM the left most option (but I think this is the emergency channel?)
4. I press the # key to bring up the radio menu and call JTAC.
5. Nothing happens.
