Topband: Topband Digest, Vol 264, Issue 19

[David Rodman]

I have the NCC-2 with inputs from two SAL-30 antennas spaced about ¼ wavelength apart.  I rarely use device since most of my low band operation is remote and I have other listening antennas.  The idea was to make the pattern more discriminating.  It helps by a few dB, in my estimation.

Hey,do any of you use an NCC-2 or NCC-1 for antenna phasing or noise reduction? Do you have any experiences and can give  me information?

Andy,
I just got a NCC-2 from a QRZ seller.
It has several optional modules.

My noise is mostly on the higher HF bands.  I know the approximate location of the source of the noise.
I installed a hi-impedance vertical element about 150ft away from the noise source and it?s connected to my B input on NCC-2.
Input A in my main TX antenna which is a yagi at 120ft.
The NCC-2 works good at removing most of the noise.   It does take some time to get used to adjusting it.
I?ve only had it hooked up a couple weeks so still learning how to use.  Feel free to contact me privately if you would like.

73,
Steve NA5C

Gentlemen,

I know from experience that the closer the noise pickup antenna is to the
noise, the better.

 The idea is to pick up as much of the unwanted local noise signal as
possible (within reason), so the noise canceller can null it out.

My best "noise antenna" was a Beverage pointed directly at the noise. :-)
