3G9A on 20M with a Coronal Disturbance

I worked 3G9A at 2330z 3:30 PST), and as you can see, they are in sunlight still: They were very easy to work, and while the Falklands is no big deal from my QTH, I am at least watching 20M to see when it is open and when it closes. They were only S7 at best, but Q5, even with some crackly static sounding…

3Y0Z: A Index Prediction

The SSN isn’t the big news for 3Y0Z, its the A and K and basically the noise level due to solar disturbances that will make all the difference. Heres the latest A index predictions: 5 on January 29 to February 3, 8 on February 4-5, 5 on February 6-8, then 8, 12 and 10 on February 9-11, 5 on February 12-14, 20 on February…

3Y0Z: The Delay and its Affects on Propagation

VOACAP Online has many new features, this one is my favorite. These are predictions for my QTH WOW – my theory that the 5+ day delay would “flip” 20M as being a better band to work them on is true. It also applies to 17M and to a lesser degree, 15M. 40 and 30M do not suffer much either. I have confirmed this on the…

3G9A/MM – Your Best 3Y0Z Propagation Test!

The 3Y0Z Team is entering the open sea. They have started transmitting as 3G9A/MM. Sure, they are barefoot running a Flex into a Hustler vertical, but that’s the point. If their signal is good from the boat, it should be better from the island, of course not today, but as they get closer. In any case, you will be able to chart when a band…

Thinking About VK0EK While Waiting for 3Y0Z

I was basically a project manager on the VK0EK project. After an initial thought of going on the trip, I realized: I hate camping in tents I hate contesting or sitting in front of a radio for too long I hate long distant traveling by anything but car I’m a home body, and for me, I like armchair traveling and seeing the world through…

Killing Top Band Noise

Here in the “noisy neighbor suburbs” the name of the Top Band RX game is steering the nulls towards noise sources using the rotators, THEN using the NCC-2 to electrically steer the antennas toward the signal source! I use the P3 to “see” how I can break up the noise. The noise pattern becomes “dispersed” and as it breaks up, I hear more signal…

3G9A: Propagation Checks

I’ve done enough testing for 3Y0Z, and realize that the best test will be to track them as they travel and when they are /MM This will be fun and exciting as we wait for this epic DXpedition.

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: Punta Arenas!

It looks like the team is now meeting in Punta Arenas. Next stop? King George Island in the South Shetlands. Their itinerary says they will leave on or around January 13 – in 3 days, so I imagine last preparations will be made. I would imagine all of the team must get to Punta Arenas and then they leave for King George together. In…
