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…

KY6R Optimized 40M Loop Frame on the Yaesu G450A

Getting the antenna square took some time and engineering I got really close today to getting this on the air (but it took a bit longer than I expected). The frame is square and I have the wire threaded through the top support element. Tomorrow I will have the Wellbrook FLG100LN Preamp on the front and the 880 ohm resistor on the back. I…

Dual KY6R Optimized 40M Delta Flags – Progress

The first flag rotator with cable PVC pipe is almost ready (I need to trench it) I took down the W6LVP loop and moved the rotator to the first flag’s mounting pipe. I also got the second flag’s mounting pipe cemented into the ground using fence post concrete: The second aluminum pipe is now curing and will be ready late tomorrow I won’t receive…

KY6R 40M Optimized Delta Flags Separated at 80 Feet Apart

At 80′ – I can rotate the second KY6R 40M loop I have a choice – I can have the second loop at 100 feet (where it would have to be fixed) with a bit better performance than at 80′ (where I can rotate the second loop). I’ll choose to rotate the second loop because the performance is not that far down, and rotating…

The DXE NCC-2 at KY6R

I’m switching back to how I used to use the NCC-2 – this time on 40M instead of 160M I know that this mode of the NCC-2 works like a champ – but this time, instead of using two Wellbrook ALA1530LNP loops, I will use my KY6R 40M Optimized Delta Flags. I think I will opt for using the preamps and 75/50 ohm modules…

Two Phased KY6R 40M Optimized Loops = 11.6 RDF!

Two KY6R Optimized Loops separated 100′ – an RDF of 11.6 and more gain Looking at EZNec, there is a very compelling reason to go with two KY6R loops for 40M. In fact, I also modeled the W6LVP loop with one KY6R Loop – and it pales in comparison. So, the plan will be to put up a second KY6R Loop – but it…

KY6R Optimized 40M Loop – Next Step

The feed line will run along the bottom 1 x 2’s and to the 75 / 50 ohm transformer. I will use a plastic electrical box to protect the transformer and resistor from the rain – and use 4 bolts to hold the ladder line that comes down from the apex and then the bottom ladder line that runs along the bottom elements. The…

Building The KY6R 40M Optimized Loop

The double walled pipe will fit in the top part of the Yaesu G450 rotator. Bolt the pipe with the redwood inside and then use two U bolts to hold the antenna frame to the pipe.  When redwood gets wet it does get a little bit heavier, but is usually doesn’t warp or split like other woods do. I was going to use fiberglass…
