Aircraft VHF communications are conducted on 118.000-136.975 MHz AM. The military uses UHF AM on 225-399.975 MHz. The US Military also operates on civilian VHF airband frequencies, mostly so Military aircraft can contact civilian aircraft as well as Military. Unlike civilian aircraft, the Military is allowed to use encrypted communications. In fact, the US Military is allowed to use almost every frequency, modulation, and encryption it deems "necessary," but thy generally avoid civilian frequencies and those frequencies reserved for non-military international frequencies. One exception is that the Coast Guard, a military organization, operates on the civilian MF/HF and VHF Marine frequencies as well as military reserved frequencies. =========================================================== Richard Van Fossan Richardv@pobox.com (253) 230-2525

Specifications:
- Transmit (TX): 136-173.9975 MHz (VHF) and 400-469.9975 MHz (UHF) - Receive (RX): 50-600 MHz (full band)The Airband covers 108-137 MHz, so the radio CANNOT transmit on any aircraft frequencies EXCEPT, perhaps, the overlap of 136-137 MHz, so if you avoid that frequency range, you should be safe.

Hi, If it can transmit on those frequencies, just put a different TX
frequency
in that row. When I have set up Baofengs for non-Hams, I put frequencies like FRS frequencies in the rows of the Ham stations.

Sorry Richard...
Forgot to add "Quansheng UV-K5(8)"
Loaded and receiving transmissions.
But, hope there is ABSOLUTELY NO possibility to TX!!!
Again, Thank You!

Most HT's which can receive aircraft frequencies do not support AM operation (air band communications are AM) and are blocked from transmitting on air band frequencies.
