Even more Trans-Pacific openings on the 40 MHz band - 6th to 9th Feb 2023

In previous posts, I reported on some impressive 40 MHz openings across the Pacific Ocean. On the 28th of December 2022, there was a 12,000km+ opening on the 40 MHz band from California to Australia. On the 25th of January 2023, there was a 10,470km opening on the 40 MHz band from California to New Zealand.

The common element in both posts was that the station in California was WM2XCC, the experimental 40 MHz station which is operated by Chris, N3IZN. Now we have reports of two other experimental stations being heard across the Pacific.

WM2XEJ: The first report is of Bob, ZL1RS in New Zealand receiving the WSPR signal from WM2XEJ in Georgia in the USA. This is interesting not only because of the 13,129km distance but WM2XEJ is a lot further east than the previous reception reports of WM2XCC in California.

These are the WSPR reports...

As you can see, the signal comes out of the noise and peaks at +1dB which is strong enough for say a good CW contact. After that, it fades away again. The opening possibly coincided with a sunset in Georgia. or a sunrise in New Zealand?

The other stations shown on the map above are from the last week and show plenty of F2 propagation on the 40 MHz (8m) band.

WM2XCW: The WM2XCW experimental 40 MHz station is located in the far north of Washington state and has now been received in New Zealand. This is significant because WM2XCW is the most northerly of the US experimental stations on the 40 MHz band.

ZL1RS... Again, most of the reports are from Bob, ZL1RS on the 6th and 8th of February 2023...

Note that while WM2XEJ in Georgia is listed as 100-watts, WM2XCW in Washington state is using a much lower 10-watts. The strong signal peaked at +3dB suggesting a weak SSB contact may have been possible.

ZL1RQ... There are several reports from Alan, ZL1RQ for WM2XCW but they are listed as being on 28 MHz. As WM2XCW only transmits on 40 MHz, it seems likely that ZL1RQ is listening on 40 MHz but his older version of WSJT-X software isn't configured for 40 MHz reports.

There is also one report from ZLBEACON with the same frequency, short locater square and software version as ZL1RQ so I presume these were from Alan as well.

WM2XCC: Unsurprisingly, most of the trans-Pacific 8m reception reports are for WM2XCC in California. Note that WM2XCC is using different power levels at different times.

VK4OTZ: There is one single report from VK4OTZ on the east coast of Australia on the 7th of February 2023.

ZL1RQ: There are several reports of WM2XCC from ZL1RQ but again, the frequency shown is 28 MHz rather than the correct 40 MHz one.
