Great tool Time Owned: 0 to 3 months.
Used primarily for AM broadcast band DXing at my listening post, I’m finding the NCC-2 delivers super deep nulls. Deeper than I had been attaining using a DX Tools Quantum Phaser. This device will unearth the weakest of signals buried by stronger ones.

The NCC-2 is relatively physically big for what it does but I appreciate the large phasing knob. Built like a tank, don’t drop it on your toes.

Reading the manual is a good idea unless you are very familiar with phasing technique. In addition, the NCC-2 can be set up for multiple radio and antenna configurations.

It’s expensive as the dickens but it is a high quality standout phaser offering immense flexibility.

Effective noise cancellation Time Owned: more than 12 months.
Unfortunately, there are many unpredictable noise sources in my suburban environment that seem to come and go. I see them as spikes on the panadapter and hear them as s-5 to s-9 hash that ruin reception of weak DX within their bandwidth. I don't have the time or energy to try to trace every noise source that comes along.

My solution for several years has been to null out the noise by phasing the receive signal from my Tx antenna with a small preamplified receive loop (I use one made by W6LVP). The bias-T circuit in the NCC-2 powers the preamp in the Rx loop. Both channels in the NCC-2 are fitted with the optional receiver guard modules and 160 meter high-pass filters.

My most problematic noise sources show up on the 40 and 30 meter bands, and these are easily nulled down to nothing with the NCC-2. Noise cancellation seems somewhat less successful on 160 and 80 meters, probably due to the relatively close spacing (only 50 ft.) between my Tx and Rx antenna.

The NCC-2 regularly enables me to hear and work DX stations that would otherwise be obliterated.

Goodby QRN Time Owned: 0 to 3 months.
I have used an MFJ 1026 with a separate noise-sense antenna for a number of years. It usually works fairly well, but can be rather finicky to set just right to reduce or eliminate the QRN here (there is severe power-line RFI more often than not).
I've been doing a bit of work on the station (new antenna, new rig, new tuner, etc.) and decided to spring for the NCC-2. Absolutely no regrets, other than that I didn't do so years ago. The NCC-2 is much easier to adjust than the MFJ 1026 and usually produces a deeper null as well. And it's resettable, whereas the MFJ 1026 usually required a fair amount of tweaking.
I have seen some say that the MFJ 1026 does the same thing as the NCC-2 and for much less money. IMO, this isn't true. Not only is the build quality far superior in the NCC-2, but it provides complete 360-degree phase adjustment up to 15 MHz, and still provides about 270 degrees at 30 MHz. And as the relative phase of the two antennas is adjusted, the gain stays constant, eliminating one issue when adjusting the MFJ 1026.
My main antenna is a 102' inverted vee with the apex at about 25' and the ends at about six feet, fed with 450-ohm ladder line to a Palstar AT2K tuner. My noise-sense antenna is a mini G5RV at about eight feet, at about 90 degrees to and about 50 feet from the main antenna.
BTW, I also installed the Receiver Guard and DXE receive preamp in the B side of the NCC-2.

WOW Time Owned: 0 to 3 months.
Afters a neighbor got a new PLASMA TV, I have been experiencing a TREMENDOUS amount of "GARBAGE" on 20 meters. At times I can not copy weak signals. Now the NCC-2 is inline with a dipole sense antenna tacked to my back fence. I can take a 20DB over S9 signal and make it DISAPPEAR! I can "tune" it to eliminate noise sources on 160 meters and copy signals that were impossible to copy before. Even if you think your noises can not be diminished, this unit works GREAT! The people at DxEngineering have been extremely helpful.
