Sunspots - Saturday July 15th 2017

Solar flux is 91 (high) and the sunspot number 58 (quite high). A=4 and K=1. At this stage of the solar cycle these are good numbers.

Home again - NOT amateur radio

After nine days away from home (7 in Devon and 2 stopping on the way) we are now back home again. The grass needs cutting and those annoying brown patches in the grass, although smaller, are still there! Obviously we did not have enough rain.

OFCOM annual report and accounts

A dead simple regen receiver

There are plenty of designs out there (try Googling "regen"). but I offer you this simple design with very few parts. It works. You may be surprised that something so simple can hear so much.

The 2m Fredbox

This was designed in 1974, when I was still "green behind the ears". It got rebuilt much later and still worked well.

The Sixbox came much later.

Rethink over climate deal? - NOT amateur radio

Is Donald having second thoughts over climate change? I certainly hope so. On this the USA is at odds with the entire world and that can't be good for one's ego. He sounds and behaves stupidly in the eyes of the rest of the world. Come on Donald! You'll look better (more presidential) if you come into line.

Sixbox 6m AM QRP transceiver

As we slowly progress to "quiet sun" years, it is worth remembering that our VHF bands are useful for local QSOs. Some years ago I designed and built the Sixbox which was a very simple AM transceiver for 6m local communications. It should be easy to build and develop further - maybe with more power and a loudspeaker amp added. I am pretty sure this has been shown before.

Groundsman's hut - NOT amateur radio

Bolt Tail in the distance. This groundsman's hut at Thurlestone Golf Club is being rebuilt. It was a corrugated shed. I expect the next time I see it, it will be completed!  The second view is a typical Devon scene with Burgh Island in the distance.

OFCOM and 5.8GHz Wi-Fi

OFCOM has made a decision regarding 5.8GHz Wi-Fi in the UK. This now legally increases the number of 80MHz Wi-Fi channels from 4 to 6 in the UK. Their hope is the extra spectrum will help broadband.
