Collins 180S-1 Watt Meter Mod

Collins 180S-1 tuner with Directional Wattmeter

Ed, AC6CX sent me a PDF copy of the 180S-1 manual, and so now I know what the fellow who did the mod to my tuner did – he built a Collins directional coupler and wattmeter into the tuner. The switches are no doubt to switch in the different readings of the meter reflected and forward power.

One day I can see using this tuner in a weather proof box and remotely control it using a wireless and fully automatic version of the URAT project that I designed a few years back. I might try a side fed loop or Bruce Array – here in Orinda, or maybe a full 40M Bobtail curtain at my next QTH in about 4 years.
