10m WSPR
On 10m WSPR I am still using 500mW. At the moment the Es seems to be favouring northern Europe and Scandinavia on 10m.
Recent 10m WSPR spots (500mW) |
Israel on 6m VHF
4Z5ML (3571km) in Tel Aviv, Israel was spotted on 6m JT65 about 99 minutes ago. This was the furthermost on 6m today. Although there is plenty of Es about, I am not so sure of the conventional wisdom that this is multi-hop Es. I feel sure that one day the experts will discover "chordal hop Es" or similar. This could explain quite a few long distance Es paths. Of course, I could be totally wrong. It would not be the first time!
UPDATE 1430z: Plenty of Es today on 6m JT65. I see that I have been received in Israel. See https://pskreporter.info/pskmap.html . It's funny how when there is a lot of 6m Es, it looks like 20m! I have still to spot, or be spotted, transatlantic on 6m this summer on 6m JT65.

More hot sun and flying ants - NOT amateur radio
For about a week now we have had better summer weather in this part
of the UK. Temperatures have been in the mid 20s to low 30s (deg C) all
week. We had one big storm which dropped humidity, but yesterday and
today are hot.
It is also "flying ant season". Whilst I was out yesterday, we had
hundreds of flying ants in our bedroom. I gather these larger, flying
ants are queens. They come out on mass to mate. It is usually just one day, then they are gone. The hot weather has not helped.

Australian flying ants - but UK ones look similar |

HF Propagation Predictions by G0KYA
See http://www.infotechcomms.net/propcharts .
Taking a peek at Steve's propagation forecasts for 10m this autumn does not look good for E-W propagation from the UK to North America. Even with a sunspot count averaging in the low 30s (possibly too high?) it looks like E-W SSB propagation with 100W is unlikely. With WSPR or JT modes much lower power is possible, but openings to the USA are likely to be much rarer than in seasons past.

Es aplenty on 10m and 6m
On 6m JT65 I have been spotted in Poland several times. On 6m JT65 RX my best DX so far is Crete SV9CVY (2729km). On 10m WSPR I have been widely spotted in Europe since the early hours of the night. This is all Es. In my experience there is often Es at night. People wrongly assume this is mainly a daytime propagation mode. On 10m, WSPR can help "smoke out" short night-time Es openings.
UPDATE 1135z: A couple of spots recently from Finland of my 1W ERP 6m JT65 signals.

Sunspots and 10m - Saturday July 23rd 2016
Solar flux and sunspot numbers are falling again now. Solar flux is 89 and sunspot number is 36 (K=3). The 10m F2 propagation forecast remains "poor".

ULF Amateur Experiments
Stefan DK7FC is always experimenting at VLF and ULF. Recently he has been radiating a signal at 2.97kHz and he has detected his own signal at 9km. This is not earth mode. He is trying to get reports from much further.

As you know I am not a great fan of OFCOM or the FCC, but I put links here so you can read their documents if you want.
