[Elecraft] Intermod filter for the KX3

[Mike Parkes]

Hey group
I have an issue here and am wondering if a good band pass filter would
help? I pick up so much sqawks and buzzing weird interference, grating
machine sounds, on my KX3 on all HF bands, it is horrible in my setting
(ground floor apartment in the city). I have the same issues on 2 meter
handhelds, noise all over the band, trips the squelch making it nigh
impossible to scan without the radio stopping on some ghost signal that is
only intermod. Same story with the KX3 2 mtr module though I can turn the
squelch up enough to keep the radio scanning without stopping on noise for
the most part. Is there any hope for HF? Would some sort of HF band pass
filter help my KX3? Or is the filtering in the KX3 already good enough? I
can't make it go away with the built in KX3 noise filters. There is this
one company across the street from me, some internet megalith place with
sat dishes on the roof and I wonder if some of the noise is coming from
that establishment. Anyway... thanks for any ideas... head for a park, a
mountain peak... I know... :)
