Hello everyone I listen mostly to the aircraft bands and was hoping to find a list of HF frequencies and well as maintenance frequencies for the majors that I can listen to here off the Florida and US east coasts. Thanks for your time
When you say "maintenance frequencies" are you referring to frequencies where pilots can call into their maintenance department in troubleshoot issues and fight?
If so the most common vendor for that is Collins (formerly known as Arinc)
Maps of the VHF en route radio network can be found under the maps and documents header.
Displays frequency assignments for the Atlantic and Pacific oceans
radio.arinc.net
Additionally the HF frequencies can be found on that page too.
I don't have other maintenance frequencies handy, but if you want to search and discover them, they will be between 128.825 and 132.0 MHz. (And theoretically between 136.5 and 136.975, I've never observed these freqs in use, YMMV)
