Frank Statham provides some additional information. "The Canadian Coast Guard used the CN 495 on the old (pre 1972) wooden lifeboats at Bamfield and Tofino, BC. Note the 1630 KHz frequency. Try loading that up into a center loaded whip on a wooden boat. I used to resonate the antenna by running the tap along the radio's loading coil while the key was down. The smell of burning flesh always accompanied that little job".The 495-2 was manufactured by Fisher Research Lab for CMC.
