Re: [IRCA] phased BoG experiment in Masset.
Easy answer — Your sample Lankford-Misek-Ratzlaff phaser Does not have actual matched 50 ohm potentiometers in the “fine” controls — They are “faked” 50’s using fixed resistors across the POT - which results in squirrelly, unpredictable or unstable nulls. All M-L-R PHASERS “sold” since that beta was built have ceramic or wire wound pots built and deployed like Lankford made his. Dallas Lankford described his 2007 Phaser as the best one ever - which is why Nick, Steve and I improved on it - making it significantly superior to the clunky Quantum Phaser and massively less expensive than the Cadillac-Tank DX-engineering Phaser. And with this e-mail, I’ll expect pedantic pencil pointing, finger waving and demands to see schematics and exact details on all changes. I’m currently building 6 more simultaneously. I’m specifically not selling them to “gotta have one / gotta shelve one...” they are for active DXERS actually posting regularly on IRCA or one of the other clubs. I’ll take questions now.

Re: [IRCA] phased BoG experiment in Masset.
Neil, I suspect that that was the case with my experiment. With the shorter wire, and unamplified, no wonder the signal was too different in strengths to get it to work properly. This will be a good spring/summer experiment when I won't need to erect the N Beverage at all, freeing up another amplifier. Do you feel there's any difference in the width between // BoGs? Also, would a stagger work any different than // wires with the shorter one being between the start/end of the longer wire? 73, Walt On Wed, Jan 9, 2019 at 5:05 AM Neil Kazaross wrote: > I'd expect that to work.

Re: [IRCA] phased BoG experiment in Masset.
I'd expect that to work. However, the issue is that you probably had considerably more signal period on the amped BOG, so you need to attenuate it to get a back null. Ideally with these Phased BOG Systems you're looking to null back end QRM while not reducing forward DX and hopefully the forward DX can actually gain a couple dB signal from the combination of two antennas. Here's an example, using the Quantum Phaser, (forgive me, Nick and Colin, but I cannot get your phaser to work this well here and will wrap it back up and take to P.O Saturday) KYW blasting in with 1062 TA carrier. Reversing phase just about killed KYW to reveal XEEP and the TA carrier was also basically gone.

Re: [IRCA] phased BoG experiment in Masset.
Bill the main amplified BoG was about 750’ long, while the parallel shorter non-amplified BoG was about 600’ long with the feed about 50’ from the primary, and the unterminated end about 100’ from the end of the primary BoG. 73, Walt On Monday, January 7, 2019, Neil Kazaross wrote: > Here are Bill's loggings with this.
