OFCOM on access to 5.8GHz

6m JT65

Things seem to be getting harder on 6m Es. I have spotted a station in the Czech Republic, but no-one else today so far on 6m.

UPDATE 1110z: With just 2 Es spots and 1 G (tropo or aircraft reflection?), this has been a disappointing day on 6m JT65 so far. Up to now I have been transceive (1W ERP), but just about to go RX only on 6m. There was at least 1 EI station who was spotted but not uploaded to the PSK Reporter database. Maybe the shack PC lost internet connectivity?

UPDATE 1120z: Now RX only on 6m JT65.

Tony's 10m Band Report - a question

Every week Southgate News has Tony's 10m Band Report. Reading this you could be forgiven for thinking 10m is still wonderful. In my experience, things are much harder than a few years ago. Yes there are lots of Europeans by Es, but far less "real" DX outside Europe.

OK, I am confused: I think this is a list of stations reported and not DX heard or worked from the UK.

Well equipped stations will be able to do far better than me, but I need someone to tell me this is a list of reports and not stations heard or worked from the UK. If I am wrong, then some people are doing far better than me!

Sunspots - Thursday July 27th 2017

Solar flux is 68 today and sunspot number zero.  A=11 and K=1.

Heathkit HW8

Some years ago I owned an HW8 transceiver. It worked very well and I managed several DX contacts. Working stations with a very modest wire antenna was remarkably easy. I know QRP CW is not for everyone, but I was surprised.

In recent years Heathkit is making a comeback. I hope this is successful.

10m WSPR

Since breakfast, my 10m WSPR TX beacon (500mW) has been on and received 119 spots, mainly in Germany and Denmark. So, plenty of Es on 10m.

UPDATE 1105z:  437 10m WSPR spots so far today. 36 unique spots, which is the best day yet this season and it is only just after noon local time!

At about 2115z I went QRT on all bands and disconnected the PC. All Es stopped here over an hour ago. Sometimes it comes back, but there will be other days. It matters not.

Trump's latest - NOT amateur radio

His latest thing (allegedly) is to ban all transgendered people from serving in any capacity in the US military.  One transgendered friend was once Mayor of Cambridge. At work no-one cared about it when this man became a woman. This person had a job to do and that was all that mattered.

Amateur VLF

Yesterday I had an enquiry about amateur VLF. I referred him to https://sites.google.com/site/sub9khz/ which has lots of data on what I did in the past. There are schematics of the receivers and transmitters I used as well as details from others. Most of my experiments were with "earth mode", although I also received several European amateur VLF stations by radiation. For receive you do not need a large antenna. Even on "earth mode" transmit the power and antenna requirements are quite modest.

Simple pleasures - NOT amateur radio

Well, some blackberries made it to the crumble, but quite a few got eaten! Simple pleasures to be for ever treasured long after the grandchildren have grown and flown. I hope they do this with their children and grandchildren.
