KX-3 4092

Hi Folks

Owned a KX3 for a while but never used portable until recently.
Antenna is a 40m dipole, coax fed. Nothing exotic.

For some reason the KX3 tuner has a problem getting a good match.
It settles on something like 1.8/1 which is not big deal except other
transcievers show near perfect match around 7.1megs.

Latest firmware ver loaded.

Now here is the odd part; above 7260 fast perfect match.
Move down 1khz to 7259 and the tuner won't match correctly.

On a 50 ohm dummy load tuner is faultless.

Some thing I noted is the VSWR reading on the KX3 seems out of line with
other equipment.

Not sure what the story is ?

in the meantime the KX3 is back on the shelf,
my K2 built several years ago is doing splendid service

cheers

Paul,

This is very unusual. Please contact customer support so they can send you a replacement.

Meanwhile, have you tried tapping ATU TUNE a second time right after the first attempt? If you do this within five seconds, the ATU will try a wider range of LC values.

Have you put an antenna analyzer on that antenna?
