Hi all
After getting the station back together, I have found something wierd,
the SWR on the 20 meter antenna (home-brew 3 el 20 on 18 foot boom).  It
used to have a pretty good 2 to 1 bandwidth, but now it is flat almost
all the way across the band.  It still seems to work, but at 14.000 it's
about 1.2-1 and 14.150 it's 1-1, and 14.350 it's 1.3-1.  The only thing
that's different is that the horizontal portion of the 160 meter
inverted "L" is down.  It was about 20 feet from the top of the tower
before.  Even though, the beam shouldn't be flat all the way across the
band. It's the W6SAI beam design.  73
