These days one can buy very low cost HB100 10GHz Doppler modules on eBay from various sources. There are various ways of using these in amateur projects. I have seen these in ATV kit and I am sure there will be WBFM 10GHz transceiver designs based on these if I look.
As there are 24GHz radar modules, I am wondering if there are WBFM designs based on these?
Perhaps some reader can point me in the direction of 10GHz and 24GHz WBFM transceivers based on the HB100 for 10GHz and similar units for 24GHz.
UPDATE 1810z: Looking on the internet, there are plenty of resources for WBFM 10GHz transceivers based on the HB100.

10m FT8 after breakfast
After breakfast I hope to go on 10m FT8 with the tiny indoor loop antenna and 2.5W. The last few days have been disappointing.
UPDATE 1337z: Just M1BXF (Gavin, local) spotting me so far. Everything turned on at 0844z. No spots of others yet.
UPDATE 1728z: Just 2 spots of me today - worse even than yesterday - and these were local and fairly local Gs! No Es here today. So far, just 2 Gs spotted here with best DX G6ZYF (70km).
UPDATE 1948z: 3 spots of me today, all Gs. On RX 3 stations spotted. No Es here today.

Optical illusion - NOT amateur radio
This puzzled me! It looks like a spiral, but isn't! I first saw this on a Facebook post some years ago.
SPAM comments removed NOT amateur radio
It would seem someone has been putting adverts as comments on my blogs. As soon as spotted these are marked as spam and deleted.

GB3PX 6m repeater
I am not a great repeater user.
Last night, on the CDARC net, someone mentioned the 6m FM repeater GB3PX at Barkway, near Cambridge.
Today, I gave it a try. It is on 50.780MHz with a 500kHz shift and 77Hz tone access. After a few false starts when I found out how to select the right repeater shift, I managed to access it. It was very quiet. I called several times but no-one was on.
Later, I may see which other 6m repeaters I can access. Somewhere I shall have to find a list with tone access frequencies.
UPDATE 1925z: Although I can access GB3PX very well, every time I called no-one responded. I can just (sometimes) access the Bury-St-Edmunds 6m repeater as well, but no others. A useful resource for a list of 6m repeaters in the UK is https://www.ukrepeater.net/repeaterlist1.htm?filter1=6M

10m FT8 hoping for better luck!
A few moments ago I turned on the 2.5W 10m FT8 to the tiny indoor loop. So far just spot by local G4KPX (14km), although I am hoping for better results than yesterday when I only got spots from 3 locals on 10m FT8 and no QSOs. There was one Spanish station yesterday that did not appear on PSKreporter for some reason.
UPDATE 1928z: Now QRT. Only spots from locals here and no Es noticed here. If anything, today was worse than yesterday!
