Can't get 160 sub working on K3

Works fine on other bands. I've tried the
"rf calibration" on the sub as well as
main and it's working fine. I must have
bumped something somehow as I can't hear
anything other than internal hiss on 160
but on 80, 40 & so on the Rx antenna is
apparently working fine.

Anyone well versed in what I might do,
please contact me off list.

Thanks,

Gary

Re: Can't get 160 sub working on K3

I have no idea. Works fine on the main rx & used to work last year
but I must have unselected something somehow for 160 on the sub.

Re: Can't get 160 sub working on K3

In reply to this post by Gary Smith-2

Thanks for the folks that answered. After futsing around with the
settings I now have the solution to this specific dilemma:

I have three filters in the sub and when I entered B Set and played
with the different knobs, I found when I narrowed the filter width,
there came a point where the sub was working as it should be. This
was the solution to the problem and now the sub is working properly
on all bands and so is diversity.

I'm sure this is mentioned in the manual somewhere but I never found
it.

Hopefully this will help others who have this same problem come up.

Re: Can't get 160 sub working on K3

Hi Gary,

It sounds like your KRX3 filters are not configured correctly - and so
at some bandwidth range(s), you're selecting a slot that has no filter
in (or perhaps a bad or improperly installed filter). You should be
able to see the XFIL display change (to indicate which slot is
selected) as you adjust the bandwidth.....
