Since 1975, we have lived in this East Cambridgeshire village. It is about 10 miles from Cambridge, 4 miles from Newmarket, 17 miles from Bury-St-Edmunds and 12 miles from Ely. In recent years the population has soared to about 6500. When we came it was about 4000. Luckily, it still feels like a friendly village.
The village has a fine church (see photo) and fully restored 200 year old windmill, the latter being part of one of the best local museums in the whole UK.

Lesser Chirpy (10m)
At the moment, at the depths of sunspot minimum, 10m is not exactly busy! In the late spring and summer 10m can be very good for Es communications up to around 1500km. Often, much further can be reached with 10m Es. Es can be effective at any part of the solar cycle.
Years ago, when 10m was good, I designed the Lesser Chirpy ultra-simple 10m transceiver. Like all simple transceivers, it is a compromise, but it is fun.
In the Es season it is capable of decent QSOs e.g. from the UK into Europe. In decent F2 conditions (may be a few years off yet) it should be possible to cross the Atlantic with it. The main limitation is the RX. Only TX if you know the frequency is clear.

From time to time I look at the webSDR at Goonhilly in Cornwall monitoring the narrowband transponder of this geosynchronous satellite. This is a very unscientific look at activity levels, which must vary a lot depending on the day and time of day. Nonetheless, it provides a snapshot of activity levels.
As far as I can tell, it is beginning to get a bit busier, approaching levels I might have expected. The last time I looked (albeit a weekend morning) there were 10 stations on SSB. This is more than I have observed in the past, suggesting more people are becoming active. By now, I was expecting the narrowband section to be full. Even now, there is plenty of space.

SDRs and amateur radio
Southgate News has a piece about the impact of SDR on our hobby, mentioning that it will soon be possible to buy a 3.5GHz transceiver for about £50. As the piece says, we live in exciting times.

Sunspots - Saturday December 7th 2019
Solar flux is 70 and the SSN 0. A=4 and K=0. Sunspots seem pretty rare!

Trinity Street, Cambridge - NOT amateur radio
On my way to my relativity course in Cambridge, I walked down this street, Trinity Street. This is one of the most famous streets in Cambridge. About 200m behind me is Kings College Chapel.

Websites - NOT amateur radio
Being fairly sedentary these days, I tend to do things that I can do from home. I created and maintain several websites and blogs not all amateur radio related. One of these is for my wife's choir www.cambschoral.org.uk . Others are mainly amateur radio related.

Choose your sweets - NOT amateur radio
To be honest, I am not a great sweet addict. If I never had another sweet in my life it would not be a disaster.
My wife noticed this machine in a Cambridge supermarket. It allows you to fill a tin with the sweets you like. I did not even notice the machine!
