If you do have a substantial single point noise source
(like my Maytag front loading washer) and have an ANC4
or MFJ1026 that works for you, the K3 will allow you
QSK CW (K3 needs transverter option) where other
transceivers that don't have this feature will rely on
an RF sensing relay in the noise cancelling unit. That
ruins your QSK and requires you to match the RF sense
duration control on the noise canceller to the semi
break in delay at the transceiver. I have a dipole in
my attic dedicated as a noise receiver for the
MFJ1026, works FB.

Hi all, 
        I have a S-9 noise level across the bands and
despite some detective work, I have been unable to
locate the source.    

I feel that I may have to resort to using a noise
canceller in order to use the bands at the home QTH.

Before I purchase one, I'm wondering if any of the
subscribers to this list use one and if so, how
effective are they?

Apologies for the off-topic post but I though I'd
canvass opinions before I buy one.

Thanks, Mark M5MDH
