Geez...I was brought up to think that less than a kilowatt was QRP. I guess I
had bad contesting elmers. Have a home-brew 8 - 4CX1000 amp for sale...was my
exciter. It was the only thing left after the fire...lost a 32 hole 4CX1000
when the YL turned off the water supply that cooled the amp so she could
water her "babies" in the garden. I wanted to choke her ;-)

Tnx for the advice, but it didn't work for me. Tried it several times after
each download of 9.27...got a bit expensive....couple months ago. And all
this time I thought I was the only one. HI HI

I believe this should be an "electrical quarter wave length" or multiple
thereof. Not to be picky..... Take into account the VF (velocity factor)of
the cable you use. gl es 73, Bruce AA8U
