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.
Australian flying ants - but UK ones look similar
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.

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.

Rally - Finningley

Sunday 24 JULY : FINNINGLEY ARS ANNUAL RALLY
 
The Hurst Communications Centre, Belton Road, Sandtoft, Doncaster DN8 5SX There will be a talk in station and doors open at 10.30am with admittance £3. The venue is all on one level. Car parking is free. There is a large indoor and outdoor trader's area with major traders, special interest groups and an RSGB bookstall. There will be a flea market. Hot food and drinks will be available all day. More information from Kevin, G3AAF on 0783 161 4640.

A list of rallies can be found at http://rsgb.org/main/news/rallies/.

As I have said before, I get sent these regularly and reproduce them here in good faith, but contact the organisers if travelling any distance to ensure the information is correct.

Geostationary amateur satellite

If all goes to plan we could have a new 13cm and 3cm transponding geostationary satellite in place next spring. Being fixed in position, Doppler should be no issue. I guess the date is a problem (these often slip) and getting it successfully in the right place and operational is in some doubt. With declining solar conditions, this could be just what we need. Of course, the dish can be fixed.

I picked this up on the Southgate News page.

6m JT65 and 10m WSPR

There has been Es on both bands although HA9AL (1455km) was the last Es report on 10m WSPR. I was spotted in Italy on 6m JT65 a couple of times overnight.
