Have a MFJ-1026 noise canceling signal enhancer...
Looking for recommendations from users of the ANC-4 or MFJ-1025 or 1026.


The "birdies" are probably NOT generated outside your QTH.
Put up a long wire INSIDE as your sense antenna.
Do NOT use an antenna that is well coupled to the transmitting antenna!

I use the telescoping, screw-in whip antenna that came with the ANC-4
and get good results on bands 160-20. I also have an outdoor vertical
wire, maybe 10 feet or so that I can hook to the ANC-4 and it
occasionally does better than the whip. My main antenna is an end fed
wire, approx. 200 feet and horizontal. After midnight I use the ANC-4
to pick out AM broadcast DX, it's surprising how well it works with
careful tuning. I don't use it much above 20m.

It is not easy to properly adjust the MFJ, but with a careful tuning,
you can null out the "birdies". Be sure to write down the settings for the
frequencies you,,, frequent.

I have to readjust my settings every 15-30 minutes, very small
readjustments but necessary.
