If you can't get the internal SWR meter on an Icom 735 (or similar
rigs) down to exactly 1:1 then either there's something wrong with the
tuner or with the tuner operator.

The tuner either works or it doesn't. There's no half-way house.
Without a tuner anything can happen. And it usually does.

There are far too many sleepless nights unnecessarily caused by the
SWR meter not being in the right imagined ballpark. Just ask
yourselves is the transmitter loaded with roughly 50 ohms or isn't it.
The SWR on the feedline hardly matters two hoots - the so called SWR
meter doesn't measure it anyway.

Do G5RV addicts realise that under even the best conditions the SWR on
the feedline is as high as 10-to-1 regardless of what the meter says.
But it doesn't seem to worry them.
