Topic starter
Hello, everyone -- I'm a Vietnam vet (ex-Huey crew chief) new to this fourm and I hope someone out there can answer a question for me (research for a book). I understand that the old Hueys (UH-1B/C/D/H) had mulitple radios (i.e VHF, UHF, FM). My question is: Was it possible for a pilot/copilot to monitor and transmit on all of these radios simultaneously? If so, how? Could he set a desired frequency into each radio and then switch back and forth by using a switch on the control panel? Could he monitor all three radios but transmit on only one at a time? Any information you could provide would be greatly appreciated.

Multiple Aircraft Radio Use
Gary,
The reason that an aircraft has more than one radio, is that the different radio's (FM, VHF, UH, HF, etc) all transmit and receive on a different frequency band.
I know of no aircraft where an individual pilot/crewman can transmit on more than one radio at a time. However, it is possible for the pilot to transmit on one radio and the copilot to transmit on a different radio.
It is possible for the pilot and co-pilot to monitor the receive function of all radio's at the same time. The problem it would be very noisy if more than one radio had traffic at the same time. Usually the pilot and co-pilot woud each be monitoring a different radio. Example the pilot would monitor FM and the copilot would monitor UHF.
The pilot and copilot each have a control panel that allows for them to select which radio to transmit on and which to receive on. (usually they would have the switches set to transmit/receive on the same radio they are monitoring.).
Hope that answers your question.
