Lesser Chirpy 10m transceiver

Some years ago I designed a very simple transceiver for 10m CW. This was a "for fun" rig, but it does work. Looking at the circuit it could be further simplified. It is already very simple. XBM 10-2 was the original name.

Sadly health issues stopped me fully testing this in the sunspot maximum years.

Maybe I should try it in the next Es season? Got to find it first!

Norwich cathedral bosses NOT amateur radio

Norman Norwich cathedral has some of the finest bosses anywhere. The examples shown are in the cloisters. Most of the stones to build the cathedral came from Normandy nearly 1000 years ago, which I find amazing.

To think this was built all that time ago without cranes and mechanical aids we have today.

Also, where did they get the manpower? There are over 1000 medieval churches in Norfolk alone

Norwich - NOT amateur radio

My brother is visiting from Devon. He wanted to go to Norwich, so we went by train. Much of the stone for the cathedral was brought be sea and river from Normandy in France nearly 1000 years ago. They built a canal to transport the stones from the River Wensum to the cathedral. The cathedral took 49 years to build. The photo show's Pool's Ferry where the canal began.

Yet more yuppy pads - NOT amateur radio

No doubt the developer makes plenty of profit from these houses that ordinary people cannot afford. Social housing does not seem to really count these days. I expect these homes will be sold to young executives working in Cambridge.

Neighbour's flowers - NOT amateur radio

Quite a colourful display in a neighbour's garden this morning. It is now late summer (autumn according to the weather forecasters) and he still has a great deal of colour. In his back garden he has lots of apples.

2m FT8

As there has been a lift on 2m for the last few days I stayed on overnight. So far today 6 stations spotted.

UPDATED 1000z: A recent 2m FT8 CQ resulted in 17 spots of me including 2 spots in Germany, but no QSOs.

UPDATE 1245z: The photo shows the 2m FT8 RX spots to now.

UPDATE 1434z: A recent 10W 2m FT8 CQ was spotted by 7 stations, but no QSOs resulted. My best DX was a spot by DL3YCX (475km). 53 stations in 10 countries spotted on 2m FT8 RX today so far.

The FETer transceiver for 80m

Inspired by W2UW (now SK) I created the FETer transceiver for 80m CW. This uses just a handful of parts, but works. It only uses 14 parts all together.

Lundy - NOT amateur radio

Many years ago, I was fascinated by this remote island in the Bristol Channel. It has a long and interesting history. These days it is owned by the Landmark Trust and run by the National Trust. I think it will be safe for another 50 years. I have not been there since 1961.

In recent years the puffin population has soared as a result of rat extermination. Lundy actually means "puffin island".
