[GreenKeys] Polar Relay ID

[Chuck Rehor]

Hi GreenKeyers,

Pls forgive my complete ignorance, but what is a Polar Relay and what does
it do? I’ve heard it mention here tons of times, and even though I’ve
followed this channel for years, I am learning slowly. I’m mostly
interested in Model 33 and 43’s (as they apply to 5ESS’s) but still
appreciate all TTYs.

Thanks!
Chuck Rehor
