Spooky. As to the radio gear, CW in the '50s? I could see it as an emergency backup but then it should have been stowed out of the way. -- Jim Mueller To get my real email address, replace wrongname with dadoheadman.

Of course, in bad conditions (low power, damaged aerials) CW will be readable below the theoretical noise floor.

Yep when I was in HS we sometimes bought military surplus gear and knew we could not use those 400hz xfmrs. In the business I am in... some of our power transformers run at approx 15khz I can hold one in my hand... the 60hz equivalent can weight several hundred pounds! |
