RTTY Teletype radioblvd.com



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
