    Opening on the 40 MHz band from Michigan to Georgia & Florida - 11th Jan
    2022

    Posted: 11 Jan 2022 07:56 AM PST https://ei7gl.blogspot.com/2022/01/opening-on-40-mhz-band-from-michigan-to.html


    11th January 2022: In an earlier post, I explained how the first contact between two of the new experimental 40 MHz stations in the USA took place
    on the 9th of January 2022.Roughly 48 hours later, the band opened up again with much better conditions.It starts on the 10th of January with N2OTO in Florida reporting reception of the 40 MHz FT8 signal from WM2XAN in
    Michigan, a distance of roughly 2040kms. The time was 21:15 UTC which would have been 4:15 PM in the afternoon in Florida.Txmtr Rcvr Band Mode Distance

    WM2XAN N2OTO 8m FT8 2039 km 21:15:00
    Later in the evening, there was an opening after 11pm local time between
    WM2XEJ in Georgia and WM3XAN in Michigan. This was around 04:15 UTC on the
    11th of January.

    The two experimental stations then proceeded to complete contacts on FT8,
    Q64A, FST4, FT4 and SSB over a 20 minute period on 40.662 MHz.
    Ken Miller WM2XAN in Michigan gives the following report on his Facebook account... "At about 03:45 conditions between WM2XAN and WM2XEJ began to develop. First noticed on WSPR, we switched to FT8 and although there was
    a struggle at first to complete the QSO, it finally happened as conditions began to peak. Then we began to switch through the modes and making
    contacts.
    04:02 completed QSO on FT804:05 completed QSO on Q64A04:09 completed QSO on FST4-12s04:15 completed QSO on FT404:22 completed QSO on SSB This was a
    long lasting event, with big signals at the beginning and end of the
    session, with a relatively quick null in the propagation at the mid point
    of our QSO’s. "
    Ken also reports using an ICOM IC-7300 for his 40 MHz experiments.
    WSPR... There were also several WSPR reports and it looks like this is
    becoming the mode of choice for beacon experiments on the 40 MHz band in
    North America.
    These are the stations that heard WM2XAN in Michigan...

    Interesting to see VE1PYE was listening from Nova Scotia.

    Outside of K8HTL which is Ken's own amateur radio call, the rest of the
    signals are typical for one-hop Sporadic-E.
    These are the stations that heard WM2XEJ in Georgia...

    It's curious to see that there were three reports from KC5LT at 348 kms.
    Mode of propagation?? Tropo? aircraft scatter? Meteor scatter? It seems to
    be a bit too close of Sporadic-E.
    It's a bit like some of the signals in that range on the 28 MHz band, it
    can be hard to be sure exactly sure of the propagation mode unless you're sitting at the radio and you use other clues.

    While none of the above is ground breaking propagation wise, it is never
    the less a first for these experimental 40 MHz stations in the USA.
