>Once upon a time when I was active the Navy-Marine Corps MARS system one of our members used an LM or 221 (don't remember which) as  CW transmitter by keying the antenna feed line. It was not the very best of armchair copy but the people he needed to contact heard him with no fills. I was logged into that net session and heard him well enough to copy. We were all in the state of Michigan and not hundreds or thousands of miles apart and the frequency was just above 4 MC.

Bill, how did that fellow match the presumably low Z antenna to the high Z connection on the freq meter ?
