3Y0Z: 20M and “Cross Quarter Days”

This morning I am hearing ON4UN very well on 20M on the Short Path, which is a polar path on 20M: The polar path to ON4UN grazes a weak auroral oval 3Y0Z is no where near the polar path that VK0EK was for the West Coast. But great news for any parts of the world where 3Y0Z is a polar path – you should…

3Y0Z: Upper Band Issue for the West Coast . . .

The predictions that 20M would be great at 0100z on 20M is not panning out. The band has closed already. VOACAP Online Prediction = starts at 23 or 24z K6TU predicts 2300z, so maybe I just missed the band being open. That is consistent with our northern hemisphere winter. This weekend I will have the late afternoon time to check. I’m going to guess…

3Y0Z: DX Engineering DV-40-P is 10 dB > dipole

The best thing about last nights 3Y0Z antenna test is to re-visit just how well the DX Engineering DV-40-P works to ZS. It has been 10 dB better than a dipole every time I have done on the air tests with Bill, ZS6CCY, so my DV-40-P is not going anywhere. I have already tested it extensively, and the ZS path is my favorite. This…

3Y0Z: Day 1 Test Data

RI50ANO was 59 on the Inverted L T 0123Z ON 30M and was POUNDING in 59+. No competition – 1 call. At 0338z he was also as loud on 40M SSB – and the Doublet was the hands down winner. An even better test were ZS3D, ZS6CCY and ZS6AFS – all S9 on 40M SSB at 0350z and the DV-40-P was reported as 10…

3Y0Z: First Stop – Atlanta!

Hal, W8HC is in Atlanta, no doubt at Bob, K4UEE’s neighborhood. This is where they staged the gear and shipped it from in the container. It seems as though some of the team will depart from Atlanta tomorrow and head to Santiago and then Punta Arenas and finally King George Island. I’m doing some interesting propagation study, and RI1ANO is just pounding into the…

Cushcraft D40 Plus 30M

After 3Y0Z my 2 element 20M yagi will be replaced by a Cushcraft D40 up 60′ and with a 30M wire added as a “fan dipole”. EZNec says keeping the wire spaced apart using the insulators I will be receiving today is fine. My model has the full sized dipole – so the coils might present some issues at the feed, but I actually…

Post 3Y0Z KY6R Antenna Farm

Since my DXE DV-40-P 40M vertical array is a killer 160M RX antenna, and the Wellbrook ALA1530LNP is also a great RX antenna, I’ll use the DXE NCC-2 to phase them! The K3 Dual Diversity will be awesome in this config. The Cushcraft D40 is the new 40/30M antenna. I lose nothing, but gain a lot on 160 and 40 and 30M. I lose…

An Easy Cushcraft D40 Mod Adding 30M

The Cushcraft D40 rotatable dipole is a great antenna – and its the same element they use on their 40M yagi. Because it uses coils and cap hats  instead of traps, it fairly efficient for a shortened antenna. One way to really make this antenna sing is to add 30M. It can be done very easily by simply adding a wire below using standoff…

3Y0Z and 17M – I’ll be Competitive There!

I didn’t see much on 15M just now – but 17M is humming, and LU’s are strong and give some indication of the band just before our sunset. The West Coast will have a very strong “pipeline” to 3Y0Z. The opening on 17M will be pretty short, but very strong. Having almost 3 dB gain and 1.2KW should do the trick. I am sure…

3Y0Z and the “Solar Rotation”

I had heard different numbers when it comes down to how long a solar rotation takes. This is because it depends on your latitude. I’m in the Northern Hemisphere and so the rotation for me is 26 or 27 days. This is important because 3Y0Z could be on the air by January 25 or so – if things go as planned. This means that…
