Title: Anyone want to see how a NCC-1 Antenna phaser kills noise?
Post by: VA2FSQ on January 15, 2013, 05:57:41 PM
I've been plagued by a neighbors high intensity discharge lights which he insists on running in the daytime.  So I bought a DX Engineering NCC-1 antenna phasing unit and an active receive antenna for the noise.  Was it a good purchase?
Here you decide!  Here is a spectrum from my P3 showing the 10MHz WWV signal (barely heard) before and after....

Extremely good purchase!  Too bad there isn't a computer interface for it!!

Hi Tom,

Thanks for this link!  The improvement you're seeing is truly amazing.  I also have the NCC-1 and a single active Rx antenna that I use with my Tx verticals.  The NCC-1 output goes to my Rx antenna input. 

I've never seen this dramatic an improvement in my signal-to-noise, but I guess my local noise sources aren't nearly as strong as yours.  I purchased the unit mostly for use on 160m, but I find that it works perhaps even better for me on the higher bands, such as 12 meters. 

If I can find a place to put a second receive antenna, I might try using that.  Also, I'm considering using a couple of larger Rx verticals (such as those provided by Hi-Z antennas).

GL & 73,

Hi Chuck,
My primary tx and receive antenna is a HyGain AV640 mounted on top of the garage.  The "noise" antenna is about 30 feet away and I use a DX Engineering active receive antenna for this.  Since it is relatively close, it only works on 40 meters to 10m, but I really only need it on 40 and 20, the noise sources otherwise are acceptable.
Very worthwhile purchase.

Have any of you used the MFJ-1025, (or 6), RFI reducer?  How does it next to the the DX Engineering one?

I use the MFJ-1026 and I am impressed. Use an external noise antenna for the best results.

Wow.  That's pretty quiet, -140 dBm after kicking it in.

Going to necro this thread.
The new NCC2is about to drop and I'm really interested in getting the whole shebang including botj active receive antennas.
Has anyone here Used the whole package with active rx  antennas? The ones they sell are coax fed and powered 8 foot CB antennas that mount to a ground rod. Any one use the full system and if so is it worth the expense?
