OT: Anyone use MFJ Noise Canceler for PC noise?

[dw-4]

Off topic quick question.

Hi Gang.
For a quick question....
Does anyone know of someone who is using the MFJ noise canceler to deal
with local computer noise?
I'm wondering if it would be a realistic expectation?
Or perhaps you have other ways you have reduced PC noise in the shack?
I'm finding PC noise very noticeable on 80 meters.

Thanks

I use the MFJ-1026 noise canceler.  It works well on 14 MHz and above, but
not as well on 7 MHz and below.  I have noise from a toaster around 14.05
MHz, and it takes that out completely.  Mainly though, I use it to take out
power line noise.  Make sure you use a good noise pickup antenna, not the
short vertical antenna supplied with the unit.  I also did the mod to swap
inputs, which allows a greater phase shift range.

Study k9yc.com/RFI-Ham.pdf and start with the chokes described there on
every cable attached to the computer, the monitor, the printer, and the
power cables for these devices. Every one of those cables has the
potential to radiate trash from that equipment.

Be VERY careful with the ANC-4. When I first moved here 8 years ago, I
put one in line with the output of my transceiver. My contesting
neighbor, K6XX complained that I was broad, so we immediately worked to
zero in on the cause. It turned out to be the RF detection circuit in
the ANC-4.

This unit works OK at the RX antenna patch point, but you will be a very
bad neighbor if you try to use it on the output of your rig.
