Can you create the same conditions when driving a dummy load?
If it happens only when using an antenna, then yes, your body may be
acting as part of the antenna system and can cause strange behavior.
I had the same problem as Panos when I was trying to operate K6DGW/MM
with my KX1 from a cruise ship balcony on a Panama Canal trip in 2005.
There wasn't much room for my wire antenna and it was obvious I was part
of it ... likely the dummy part of the load :-) I had the counterpoise
grounded to the ship, but it was about 2.75 meters long. I discovered
that if I grounded the radio itself directly to the ship [fortunately, I
had a couple of short clip leads with me and I managed to get the teeth
of one through the paint on the rail [there is a LOT of white paint on
ships], the problem went away. www.foothill.net/~andreaj/Ham43.htm
