Vegan friendly shoes - NOT


Brighton is the UK seaside place that never sleeps. It is also the place where anything goes. The photo shows a shop selling vegan and vegetarian footwear.

Brighton Pavilion - NOT amateur radio


 This is a photo of Brighton Pavilion earlier today. 

VLF Earth-mode blog

 Some years ago I enjoyed experimenting with utilities assisted earth-mode at VLF and was amazed by the range I could achieve with 5W. These results were put into a blog that is accessible via my main G3XBM website.

Operating patterns

 It would appear I am a creature of habit! 

I seem to go on 10m FT8 RX most of the day with a few minutes of QRP TX early on. Occasionally my QRP is spotted. More often than not, it isn't!

Just when it gets dark, I QSY to 630m WSPR RX for the evening. If I can fix my transverter I hope to TX again this winter as there seems to be fewer people TXing, but plenty RXing.

472kHz WSPR RX

At 1814z, I QSYed from 10m FT8 RX to 630m (472kHz) WSPR RX. So far, nobody spotted. I am using the earth-electrode "antenna" in the ground.

UPDATE 1943z:  Still no spots.

Facebook memories from 6 years ago - NOT amateur radio


How time flies! This was 6 years ago and feels like yesterday. 

Crystal set DXing

One of my aims was to make a crystal set that covered VLF  to VHF. This would probably have had to been several RXs in one box or at least the RF parts separate.

Crystal sets can be great fun. They are simple to make and need no power. On HF, some remarkable distances can be heard with patience. 

These days there are far fewer English language broadcast stations on HF. Many are now internet only. Despite this, the challenge remains. My crystal set DXing website may give you some ideas.

Web SDR RXs

A reminder that there are lots of web SDR RXs on the air, so you can see what shape the bands are in in other places. If you have a high local noise level, these are also useful.
