I fought noise on MW thru 20 at my QTH. I used a 1026 with great success, but it took running a second antenna very similar to the first to null out the noise. I was running a dipole and I put up another made out of very small wire on the other side of my lot at about 3/4 the height, but it was oriented the same direction and was dimensionally the same. It was only then I could null out the noise. I tried 3 or 4 different configurations for the second antenna, but it was not until I made it similar to the primary antenna that it worked.
I also tried the NCC-2 with similar results - the second "similar" antenna was the right answer for both boxes. I returned the DX box.

Hi all, I'm looking at replacing my finicky MFJ-1026 with a DX Engineering NCC-2 this season but I have a couple of questions for anybody here who's got one. At the moment I have one TX antenna for 160 (inverted-L), one TX antenna for 80 (inverted vee), a K9AY RX loop for both and an AUX vertical antenna, fed with RG-6 and split two ways (half to the K3s AUX port, half to the MFJ-1026 sense antenna port). Both TX antennas run come off a remote Ameritron RCS-12 antenna switch, which also switches my 40-through-10 Yagis. Running QRO with a KPA-1500. Before I spend $800 on this box, I've got to ask if my present antenna configuration will work even somewhat effectively through the NCC-2. I'm on a quarter-acre city lot and very fortunate to have the antennas I have. No room for Beverages or a distant tower for a Waller Flag, etc. I've got high levels of electrical noise from the industrial park less than a quarter mile away, and likely from multiple sources therein, plus nearby homes' wall warts, etc. In other words, I don't think it's one specific noise source that's raising the noise floor to S9+10, but I'm looking for any way to improve S/N on Topband and 80. So with the K3s and KPA-1500, then antennas as described, is there any reasonable way to connect this up and if yes, should I expect a noticeable improvement? --------------------------------------------- 73 and Good DX Peter, W2IRT President, North Jersey DX Association DXCC Card Checker Letter O Manager, ARRL Incoming 2nd District QSL bureau ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to h...@optilink.us ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
