OFCOM annual communications market report

OFCOM as released its annual report on the communications market.

DXing with crystal sets

OK, a confession: it is a long time since I last listened with a shortwave crystal set.

One thing is certain: at the right time it is possible to hear true worldwide DX, and not via relays.

These days there are fewer English language SW broadcasters and it is much tougher. We are also in a period of declining solar activity, so fewer HF bands are open and these stay open for less time. Nonetheless, crystal sets are easy to make and require no power. DXing with crystal sets is a fun activity.

One of my many planned projects is a multi-band crystal set capable of covering from VLF to VHF. It may never get made, but this would be fun.

Perseid Meteor Shower

See http://spaceweather.com/ which writes:

"This week, Earth is entering a stream of debris from huge comet 109P/Swift-Tuttle, source of the annual Perseid meteor shower. Specks of dusty debris hitting the top of Earth's atmosphere at 110,000 mph are burning up in the night sky, producing a spray of shooting stars from the constellation Perseus."

Wicken windmill - NOT amateur radio

Yesterday we did a walk at nearby Wicken where this windmill is. There is another at Wicken Fen which used to pump water. I think this one ground corn for flour.

Sunspots - Thursday August 3rd 2017

Solar flux is 75 today. Sunspot count is 12.  A=5 and K=1.

Return to 6m FT8

Actually, I was going to go on 6m MSK144 RX, but the frequencies recommended in WSJT-X v1.8 are not those I expected, so I have returned to FT8 instead. I see that M1BXF (14km) copied my brief CQ, but mostly I am RX only.

UPDATE 1925z: Best DX on 6m FT8 RX this evening is G8AQP (123km). This is probably aircraft reflection, although it could be tropo.

UPDATE 2035z: G3YDY (65km) is the latest on 6m FT8 RX. I think I'm too late for Es.

UPDATE 2118z:  Although I have spotted no new stations in the last hour, I think I'll remain on 6m FT8 RX overnight.

Near Wicken Fen - NOT amateur radio

This morning we enjoyed a walk near Wicken Fen. Fenland skies are large and, in their own way, beautiful.

The walk was longer than I thought. These days I find it harder to judge distances and speeds.

Old friends - NOT amateur radio

We got a surprise visit from some old friends who moved from our village to the Cotswolds some years ago. They just turned up in their camper van. They stayed for a cup of tea and came back for lunch the next day. The photo was taken as they left. It was good to see them.

Where I was born - NOT amateur radio

It is fun to say I was born in a grand stately home, but I was! After WW2 Flete House was a nursing home. In another age, I would have been born in a very modest place.

I am pretty sure I've posted this before, but it is fun to pretend I was born of nobility. 😏

20m FT8 RX overnight

Well, as an experiment I stayed on 20m FT8 overnight. There is a big take-up in the USA and Europe of this new mode. I lost count of the USA stations spotted using 20m FT8, but it was at least 21. In the other direction Kuwait and all over Europe were spotted. There is little doubt this will become the de facto digital mode for QSOs, especially on 20m.

It is a pity there is not a WSPR mode with a shorter period, maybe 30 secs. Several brief openings are missed on WSPR and WSPR is an ideal beaconing mode.

UPDATE 1708z: JA1BOQ (9484km) is currently the best DX on 20m FT8 RX.
