Hello all,

I have just acquired a Kenwood TS-440Sat (with auto-tuner). My antenna is
about
150' of 'random wire' (of which 60 feet is in my attic, on the way to the
70+feet that is
'in the air'). I want to work all bands (160 - 10). Should I just turn off
the auto-tuner, or use
it in conjunction with my AT-180, which tunes 160m, as the 440-AT does not)
or
just bypass the AT-440 tuner altogether and just use the manual tuner? In
other words,
tune the AT-180, then let the 440-AT take over? Or just use the AT-180 for
160-meters,
and let the AT-440AT tune the rest of the bands (bypassing the AT-180)?

Thanks,

Dave WB7AWK

I would recommend not using the TS-440SAT tuner. It is only configured
for a very small range of tuning. The AT-180 is designed for a much
greater range of tuning mismatch.

I own a TS-440SAT and an Icom 756Pro ... the older style tuner in the
Kenwood can handle more types of mismatches than the Icom relay system --
that said -- neither stack up well to a full featured "analog" tuner. It
will really depend on what frequencies you will use the most and your
specific antenna situation. I would try each separately in your situation
and then you have your answer -- part of this hobby is learning through
experimentation.
