Contact on the 40 MHz band in the USA between two experimental stations - 9th Jan 2022


9th January 2022: In the second half of 2021, a number of amateur radio stations in the USA applied for experimental permits for the 40 MHz band... see this previous post.

On the 9th of January at 04:15 UTC, WM2XEJ in Georgia managed to complete a two way FT8 contact with WM2XAN in Michigan on 40.662 MHz. (Note: Local time in the USA would have been late on the evening of the 8th)

The distance was around 1,230 kms and it's possible that the propagation mode was mid-Winter Sporadic-E. WM2XAN reports that it may have been due to Auroral-E. The K-index was at 5 late on the 8th of January which gives some credence to the Au-E theory.

While some of the US experimental stations have exchanged WSPR reports up to now, this is I think the first actual contact between two US experimental stations on the 40 MHz band.

The PSKReporter website shows that WM2XEJ was also heard locally by KS4OT in Georgia.

Once we get to late April and early May and the start of the Sporadic-E season, 40 MHz contacts and reports like this should become more common.
