I was playing in the 160 last weekend and experienced some problems with my
setup when I tried to run power. I have a 160 dipole fed with ladder line
and a Vectronics 1500 tuner. I used it all  Friday night at a 100 watts and
did not have any problems tuning. On Saturday I put one of my amps that will
do 160 in place. When I went over 200 watts, the tuner would start to bark
and arc across one of the tuning capacitors. I tuned it up on another 40
meter antenna and my th11 beam and it worked at full power fb. So any
thoughts as to why it will tune up nicely on 100 watts, but will bark at
anything more???

THat problem seems to be quite common with most socalled  KW-tuners.
The only one I have had that worked witout problems was the Ameritron ATR-30
and a home-made tuner
with heavy coil and vaccum capacitor !
