I have a regular 80M morning sked with a friend in the Sierra Nevada mountains.  I am located in the San Francisco Bay area.  My rig is a CMS suitcase spy set.  It puts out about 5 watts and because the osc runs continuously during TX, a backwave as well.  I measured the backwave at 1.6mW.  My friend can often copy the backwave.  Distance about 200 mi.  Full size dipoles at both ends.  Under the right conditions, it doesn't take much.

>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 ?
