Lots of good suggestions, but don't overlook something simple. A while back
I had similar symptoms on 75, and it turned out to be a loose PL259 on the
lightning arrestor at the base of the tower.

Subject: [TenTec] swr
Hi All , I have a TT Orion II and when I use it on 160 with a palstar
auto tuner , TT Titan III 417Amp and a new zero five vertical antenna
The swr runs a muck. This only happens with 250 watts or more , the swr
will read on the radio or tuner say 3.1:1 the Palstar auto tuner
knocks it down to 1:1 and all is fine then all of a sudden maybe in the
middle of a qso the swr will rise to 3 .1:1and I have to re tune and of
course this will send the amp into a fault position . It is almost like
the tuner just stops working . I can't remember if this has happened on
other bands but it will happen on 160 . to answer some questions , no
the tuner in the OII is not on when I use the palstar tuner . And Yes I
have 48 radials down at 45 foot each. I use no grounding inside the
shack but my antennas and coax are grounded outside the shack . Is the
problem the radio , tuner , amp or what .And by the way the antenna
plays real nice on all other bands . thanks for your input in advance
. all the best ! John kb2huk
