As I am on 8m, I am on 10m WSPR TX with 500mW from the W5OLF beacon. It is
now 1509z and spotted by 13 unique stations so far today.
UPDATE 2045z: 27 unique stations have spotted me today. Now QRT.

10m QRP WSPR TX

Since 0726z, I have been on 10m WSPR TX with my tiny 500mW W5OLF beacon. It
is now 0840z and, so far, 6 unique stations have spotted me. This looks
like Es in the main.

8m experiment (Friday)
Posted: 22 Jul 2022 02:35 AM PDT
http://g3xbm-qrp.blogspot.com/2022/07/8m-experiment-friday_22.html
Much to my surprise I was spotted by 3 unique stations yesterday on 8m FT8. Shortly, I hope to be on 40.680 MHz USB dial QRP FT8 again.
Full FT8 reports and locations (I cannot call this a QSO because of OFCOM - what utterly crass stupidity!!) were exchanged with one station in central Europe.
UPDATE 0937z: Spotted by HC02 (1808km) in southern Portugal.

Es (sporadic E)
Posted: 22 Jul 2022 01:26 AM PDT
http://g3xbm-qrp.blogspot.com/2022/07/es-sporadic-e.html
July usually marks the end of the main Es season in the northern
hemisphere, although Es can occur at any time. Usually the peak months are
May, June and July. Some remarkable distances have been spanned on 6m,
although I still believe many of these long paths are some sort of chordal
E propagation, not involving multiple hops. These very long openings are
too frequent for multiple hop Es to be probable. Yes, this may occur on occasions, but I am convinced there is some other mechanism.
One thing I have learnt is experts are frequently wrong! Often they parrot myths that are just not true that they heard years ago.

ISM band access licence free?
Posted: 21 Jul 2022 11:56 PM PDT
http://g3xbm-qrp.blogspot.com/2022/07/ism-band-access-licence-free.html
The ISM bands were agreed internationally so that things like microwave
ovens could use spectrum without the need for a licence.
In different administrations the rules vary, but they may allow access at
very low power for serious experimenters and without the need for a
licence. It is possible that WSPR or FT8 could legally be sent in the ISM
bands without a licence. Callsigns are arbitrary.
Please check what the rules are in your country. It may be a way of many gaining legal access to bands like 8m for serious experimenters.
