My newest antenna at Area 57 aka 125 Contest Ln An 8el Sterba Curtain Array

It's just a wire antenna
But it has an estimated 8db of gain over a dipole
Mine is ladder line fed from a home made 9:1 Balun
It appears to work much better than my 20m ground mounted vertical that has 32 radials
Very few trees here and what we do have are short scrub brushes
So I installed two surplus Telephone poles

The LA QSO PArty is coming..........

Work at Area 57 AKA 125 Contest lane begins on the holes for the Two Towers

Follow up 4 December 2016

Rented a very large CAT Backhoe with supposedly rock teeth
got a bit deeper on all the holes but the north Guy anchor needs to go Four more feet
yup I am in solid rock at only two feet down

Ordered a large SDS MAX Hammer Drill and a couple of bags of some stuff called DexPan
which is supposed to go in the drilled holes in the rock and twenty four hours later will have expanded enough to break the rock

We shall see if this works, at this point I have my doubts
and may need to move my Northern Guy anchor out fusrther and pary I don't hit another Vein of the same rock !

I guess this is my real welcome to North Texas :)

-------------------------------------------

Rented a small back hoe got most of the holes dug for the front tower Then at the front Guy anchor point I hit shale rock while only down 2 feet So now I am on hold to find a much bigger track hoe and or a jack hammer !!!                                       

Mean while I now have started on wiring for the
new Ham Shack building














I also received delivery of 8 utility poles that are
begging for my attention I plan on using these for
a large Rhombic antenna on the back 24 acres















All nine elements of the YCCC low band Receive
array are now up however the electronics are not
mounted as of now as they were getting destroyed
by lightning.
So I am building some rather large RF chokes to
go in parallel with some inexpensive lightning
arrestors I bought from Mouser Electronics











This image taken before I had all the elements up
wife like to call this one the Wagon Wheel

Cheers!

W4ZV's Pile Up buster Technique..........(For the K3 with cw skimmer)

KQ5S wrote I looked at this. The reason I want to use SKIMMER is to help locate where an OP is listening. By having my own SKIMMER I am able to see 599 or a call sign almost instantly and can click on the call or 599 and QSY to where it OP is listening (a little RIT helps to move off the exact frequency). The RBN only shows calls and there is the obvious internet latency. I am not sure this would work for my intended purposes.

That's exactly how I use Skimmer for pileup busting. You need the following: 1. K3 with KXV3 and KRX3. 2. LP-PAN ~$200...probably don't need the preamp option. 3. LP-Bridge free...allows running Skimmer and N1MM simultaneously 3. CW Skimmer software $75 4. A decent soundcard $100...see http://www.telepostinc.com/soundcards.html 5. P4 2.5 GHz computer...mine cost $90 on eBay.

You do NOT need: HamRadioDeluxe PowerSDR NaP3 (I haven't tried it but it's not necessary for what you described) CW Skimmer includes OmniRig which is all that's needed to drive the K3 directly (none of the above is needed).

The only limitation is that you're limited to 24 kHz bandwidth, which is a limit Alex VE3NEA imposes on the "Softrock on IF" mode. However I haven't found any pileups wider than 24 kHz! You do need to set the Sub RX on the DX station because Skimmer only sees IF OUT for Main and because the K3 always transmits on Main (VFO A).

The procedure is:

1. Tune in the DX station. If you prefer using the Main knob, double tap A>B to copy everything to the Sub RX. If you want to listen to the pileup and the DX station simultaneously you can set L-R MIX audio options in CONFIG. I use a Pileup Buster Macro to set everything up with a single button press.

2. Next set Main (VFO A) to the approximate center of the pileup. Skimmer will then see +/- 12 kHz around VFO A.

3. Listen to the DX station. When he answers N6KR, look for the "N6KR 599" decoder dot on the display.

4. Click the dot and you're ready to transmit.

I usually crank in ~50 Hz XIT so I'm not dead zero beat with others doing the same thing. :-)

Believe it or not, I've actually busted some huge pileups without even listening to them. One I recall vividly was the ST0R pileup on 160 in August. 73, Bill ---------------------
