I was told this system was removed from a U.S. Navy JRB aircraft in the 1960s.... more info (and pictures) below! | |||||||||||||

This is my Home-Brewed Tuner for Command Transmitters; it will tune a 40M or 80M Command Transmitter (12 ohms) to a nominal 50 ohms. It consists of an air variable capacitor in series with a 4:1 UNUN. The capacitor is from an HT-37 transmitter with several rotor plates removed. The input is at the top and the output SO-239 jack is on the back side.

My AN/ARC-5 system, as well as my SCR-274N system, is powered by an 18A 28V Astron power supply (25A ICS) with a pair of tractor batteries in series across the output. Without the batteries, the startup current spike will trip the power supply. When I want to save my ears, I'll feed 550V from a Home-Brewed power supply, along with 28V, into the MD-7 instead of using the dynamotor. But dynamotors as just SO cool.....
Yes, that's a furniture mover the Astron and batteries are on....
I was told this AN/ARC-5 system was removed from a USN SNB or JRB in the early 1960s. This type of aircraft was used as a trainer, transport, or general utility aircraft.
