Big Mag Loop EZNec Plots

Two Big Mag Loops Phased Using the NCC-2 The KY6R “Big Mag Loop” – 25′ circumference with 8′ diameter  With two of the Big Mag Loops pointing in the same direction – we get this pattern: Two Big Mag Loops “In Line” and phased offers a nice pattern – both are pointing North and South Of course, these two aren’t always pointing “in line”…

Trying a Large Magnetic Loop

The NEW KY6R Loop – Now a 25′ Circumference Magnetic Loop – on two 8′ pieces of Redwood Last night, once I figured out (actually remembered) how the NCC-2 worked – with the two antennas in its 2 inputs, I was disappointed in my “KY6R Optimized 40M Delta Flag”. Sure, it worked, and in a previous test it did work well when phased against…

Taming The NCC-2 Beast

I’m wrestling with several variables at one time – the NCC-2 is an enigma wrapped in a riddle The NCC-1 and NCC-2 are very interesting units, but quite “counter-intuitive”. Couple this with two antennas of different types and two different ways to feed these signals into the K3, and to top it off – two antennas can be rotated. “Tuning for a Null” is…

Two Wellbrook ALA1530LNP’s or W6LVP’s vs. the KY6R Loop on 40M

In EZNec, its no contest, the KY6R Optimized 40M Delta Loop kills the Wellbrook and W6LVP Loops A pair of the KY6R loops still beats the Wellbrook or W6LVP loops on all bands from 160 – 20M. It sure seems like the small “aperture” loops are very good for their size, but bigger seems better as far as signal goes – and when you…

Receive Antenna Testing: The “Scientific Method”

I’ve learned not to be in a big hurry when designing and building what is essentially a “potential” new antenna / product. First, there is the EZNec model, then there is the build, then extensive product testing must be done – else you might believe your product is better than others already in the market. In fact, this ends up being quite the journey…

So, How Does the KY6R Optimized 40M Delta Flag Perform?

The KY6R Optimized 40M Delta Flag Bottom line – one KY6R Loop performs as expected – in some cases, the gain is zero and the UrbanBeam beats the loop, but in others they are the same. The UrbanBeam has 6 dBi more gain than the “unity” KY6R Loop (that’s with the Wellbrook preamp), but the big difference is that the polarity and Front to…

SDRPlay RSP1A Panadapter and K3 Diversity Receive

The 40M FT8 “Watering Hole” I got the RSP1A hooked up as a Panadapter for the K3. At first I was disappointed until I read Tom’s Win4K3Suite online manual and found that you have to download and install a special panadapter scope driver and then set the Global Offset to -6530. Once I did that, the K3 Win4K3Suite looked at good as the Xonar…

Dual Diversity Receiver Testing

I’ve completed a few tests already, and have several more to do As expected (or at least hoped), the Wellbrook FLG100LN beat just having a 75 / 50 ohm xfmr at the feedpoint There was no contest with this first test, and the Wellbrook preamp is the clear winner. This configuration of the NCC-2 was great for the KX-3, but it just isn’t as…

The New KY6R Station

The RF Noise on 40M has me changing my station (yet again) . . .  A friend says I change stations more often than I change my underwear. That is true (figuratively speaking of course!). A few years ago, I was a happy camper chasing DXCC on 160M and I had a similar setup – two Wellbrook Loops, an NCC-2 and on 160M –…

Huge Success: The KY6R Optimized 40M Delta Flag!

The completed KY6R Optimized 40M Delta Flag  I did some testing today – one without the Wellbrook FLG100LN, and one with. There is no comparison – the Wellbrook preamp is what makes my design sing. The packaging of the remote preamp fits the frame I built perfectly. I now have a better version of the ALA1530LNP that I loved so much a few years…
