Ham Radio DX joins us again on another interview to talk about his experience on how to work sporadic E for long distance comunication from 10 meters through 2 meters.
This morning I was randomly checking the 6 metre WSPR results for my station and I noticed the following:
Why is this interesting? Well let's show all the stations on a map.
Notice how the stations are evenly spread out. The red circles are estimated midpoints of the path. If this was Sporadic E (remember we are still only just into Spring here in VK) then there was potentially three clouds that had formed or, a really intense cloud somewhere over the north of Tasmania which was allowing 6 metre signals to be much shorter than normal. You'll notice the signals to VK3DXE and VK3II were in the + range at around 550km. Of note is that the above stations only received one spot from me at this time of 04:44 (2.45pm local).
Just another example of how WSPR finds potential openings that would otherwise remain undiscovered.
On the evening of 31st January there was a small opening to ZL on 6m as indicated by my WSPR reports - although not overly strong. Several mainland stations were working across the Tasman on 6m. I tuned to ZL2WHO/B on 50.024MHz and had a clean 5/6 report on it.
As the 6m yagi was already pointing that way I decided to leave the 2m radio running on ZL2WHO/B on 144.271MHz JT4D, not expecting anything to come about. At 0822 UTC a short burst from the beacon came through and decoded at -16. Screenshot below.
The trace is quite clearly visible. Hepburn charts indicated at the time some intense tropo off the coast of ZL.
Distance is 2,381.9 km. Also below is the WSPR signal spots over to ZL at the time. Notice the two really strong signals either side from 3WE to ZL. This path is difficult to estimate short skip Es as there is no stations 300-700km off the coast of Tasmania.
