I recently acquired an astronomical amount of military radios that I will be listing over the next several months. This is a very nice RT-712. This is the pressurized version of the Collins 618T. This has an outter case suitable for high altitudes. I dont think this is all here. Its clearly missing a few modules? This is untested as I do not have the time to test every single item extensively. Youre buying it as is because of that. If you have any questions, please feel free to contact me at any time.
