Yesterday I listened, via Zoom, to a most interesting lecture by an economics professor on how to take account of climate change in accounting. This was part of my University of the Third Age in Cambridge (U3AC) lectures.
One of the "take away" remarks was that he thought we would be able to feed the world as long as we eat less meat. In my view, we will be persuaded by adverts to enjoy alternatives, if only on certain days each week. Beef and lamb need huge amounts of land and water. If we don't change, we will all die!
As a carnivore who enjoys steaks I shall not find this totally easy. Eating less lamb and beef and more pork and chicken are good starters. Personally, I could be a vegetarian despite enjoying my steaks, certainly on some days a week.
My 10 year old granddaughter has been vegan for over a year and some of her food has been really tasty.
USA folks may be interested in the 75th Orlando HamCation that runs from February 11-13th in Orlando, Florida. There are 65+ commercial traders and a huge car boot sale area. Do check with organisers first before travelling.
See www.hamcation.com .
OFCOM today emailed me about their latest proposals for mobile spectrum.
Despite 2 further chase emails this week, I have still not heard about how my 8m NoV which I submitted last October is progressing. It seems if you are talking money/revenues they are interested. Otherwise, you just get ignored. I am totally out of patience with OFCOM, who appear to have zero interest in customer care!
Both my MP and the RSGB have been contacted. OFCOM come over as a totally inept QUANGO. I have had dealings with OFCOM for many years. They seem as inept as ever.
UPDATE 1707z: Just had a response from my MP who is on the case. Best thing she could do is vote to disband this disfunctional group. Response from OFCOM? Still nothing.
The 70cm FT8 activity contest is tonight starting at 1900z. I can only run 2.5W (10W on SSB) maximum to my 2m big-wheel antenna, but probably will be on for a while.
UPDATE 1656z: Just QSYed to 70cm to check SWR etc. All seems fine. Spotted by M0IEP (155km) on TX. Nothing spotted on RX yet.
See https://www.rsgbcc.org/cgi-bin/contest_rules.pl?contest=70cmsgmac.
At the moment I am on 10m FT8 RX only with 16 stations spotted.
UPDATE 1345z: 257 stations spotted on RX today so far.This was this evening, although I only stayed on for 28 minutes because of my poor voice. As usual, I was using 10W to the 2m big-wheel omni antenna. My biggest "get away" was a station on the south coast. In all, 4 QSOs were had although many more would have been possible had I stopped on longer.
Using 2.5W and the 10m end fed antenna, I was copied by 4 stations with the furthermost G4MSA (222km). On RX, 101 stations spotted at 2058z, with the furthermost 4X1UF (3513km).
UPDATE 2140z: 147 stations spotted on 160m FT8 RX this evening.
Still waiting any progress update from OFCOM. No email today, despite 2 emails from me in last 24 hours.
As far as I know, this is still on. It is in Orlando, Florida, USA this Thursday. As always, check with organisers first before travelling far. This may be of interest to people in the USA.
One advantage of being near Cambridge is we have a vast choice of courses for our University of the Third Age. Often we can tap into the knowledge of some very clever people.
I go into Cambridge to learn about Medieval History on Fridays and attend a course on Quantum Mechanics at home on Zoom on Tuesday mornings. The course on quantum mechanics is given by a Cambridge Ph.D man. He is a very good communicator, but it is hard.
The important things are the "take away" remarks. Repeated experiments seem to prove that quantum mechanics is right and our "conventional" view of reality is flawed. Indeed, our whole beliefs about space and time may be wrong.
This is as much about philosophy as physics.
After a brief period with 2.5W TX, I am RX only. So far today (at 0924z) just G6TUS (18km) spotting me and 15 stations spotted on RX with the furthermost 4I1EBC (10661km).
UPDATE 1217z: 261 stations spotted today on 10m FT8 RX with the furthermost VK8NSB (13781km).
UPDATE 1350z: 333 stations spotted on 10m FT8 RX from all over the world.
UPDATE 1520z: 387 stations spotted so far today on 10m FT8 RX.
At the moment the usual site I get my solar data from seems to be offline. I shall add numbers as soon as I can.
UPDATE 0930z: This site is still not responding. I shall try again later. If it still fails, I shall have to find a new source of data. See https://dx.qsl.net/propagation/index.html . It seems the host site dx.qsl.net is not working at the moment.
UPDATE 0938z: It looks like the NOAA site (where the data comes from?) is undergoing maintenance.
UPDATE 1214z: Well, the dx.qsl site is now working, but the best data is 2115z yesterday, not today. This is what follows.
Solar flux is 127 and the SSN 83. A=8 and K=2. Remember, this is late yesterday, not today.
The 10m antenna turns out to have quite a reasonable SWR on 160m.
Just for fun, I tried a few CQs on 160m FT8 TX with this antenna and was spotted by 2E0VDS (30km) and G0BNR (37km).
On 160m FT8 RX 32 stations spotted by 1955z, after about 15 minutes!
UPDATE 2118z: 157 stations spotted on 160m FT8 RX.
As usual, I am on 10m WSPR TX with 500mW and the W5OLF beacon. So far just local spots of me by G4KPX (14km).
When not in use for other things like FT8, I use the 10m antenna for WSPR TX.
UPDATE 1235z: 4 unique stations have spotted me today so far.
UPDATE 1923z: 5 unique stations have spotted me today. Now QRT.
After a very brief period on TX with 2.5W and the V2000 vertical omni antenna, I am now on RX only.
So far, just one spot on TX by G0PQO (50km) and nothing yet on RX at 0957z.
UPDATE 1326z: 5 stations spotted so far with the furthermost OZ5TG (738km). Judging by the strength (huge!), I suspect this was aircraft reflection.
UPDATE 1735z: 14 stations spotted today.
A local amateur has set up a personal beacon on 4m. He is about 3km away. I have no 4m antenna, so I tried reception with the V2000 vertical omni antenna and the 2m big-wheel omni antenna. Good copy was possible despite the power being only 10mW.
It would be great to get an update on my 8m NoV application to OFCOM submitted last October! It is now 4 weeks since I requested an update on progress.
My NoV application was submitted 4 months ago, and I have still been told nothing. The NoV (hopefully) ran from March 1st 2022, which is just a few weeks away!
See https://sites.google.com/view/g3xbm4/home/vhfuhfmicrowaves/8m-band .
UPDATE 1925z: Nothing (again) today. Am I surprised? No. I have written yet another letter requesting a progress update by return. If this was private industry, someone would be accountable and either retrained or sacked.
For the next few years we can expect HF conditions to improve. Some days will be poor but on average things will get better until about 2025. 10m will be good again and we might even see some F2 openings on 6m. I hope you have fun! 😁😁
It is surprising this is not busier: I guess for most the effort is just too hard. Many DXers just go out and buy a new rig and linear. Soldering iron? Which end do I hold? RF - what is that? 😁
Solar flux is 124 and the SSN 83. A=15 and K=2.
This morning our grandson rang the church bells at Bottisham about 5 miles from here. He has now rung bells in 4 places.
The challenge is often trying to make the simplest rig that actually works. Often it is receiver that is the weakest link. With modern rigs, mW signals can often be dug out of the noise.
One classic is the Pixie and its predecessor the Micro80. Pixie kits can often be bought from China at stupid prices. These work and allow real QSOs, but they are let down by the RX. The challenge is to get a rig where the RX is up to the job. Often I do not call CQ in case a weak signal I cannot hear is already there. With QRP, calling others is often a better approach.

In a few moments I intend to go on 6m FT8 with 2.5W. Unless I get a response I shall be RX only.
UPDATE 1354z: 6 stations spotted on RX (all G) and 1 station spotted on TX - G0PQO (50km).
In a few moments I intend to go on 10m WSPR TX with 500mW from the W5OLF beacon.
UPDATE 1330z: 3 unique stations spotted. Furthermost is EA8BFK (2880km).
UPDATE 2200z: QRT. 4 unique stations have spotted me.
In a few moments I expect to be on 6m FT8 with QRP and the V2000 vertical omni antenna.
UPDATE 1024z: After a brief period on 2.5W TX, I am RX only. No spots at all yet on RX or TX.
UPDATE 1910z: QRT soon. In all, 7 stations spotted, all in the UK.
In a few minutes time, I propose to go on 10m WSPR TX with 500mW from the W5OLF beacon.
UPDATE 1021z: 4 spots so far with furthermost EA8BFK (2880km).
UPDATE 1413z: 5 unique statio s have spotted me today so far. Furthermost is FY5KE (7110km) assuming he is not a pirate!!
Most of the day I have been on 10m WSPR TX with 500mW from the W5OLF beacon. 5 unique stations have spotted me today so far.
UPDATE 2200z: QRT soon.
Apart from a very brief period on TX with 2.5W and the V2000 vertical omni early on this morning, I was on 6m FT8 RX. 5 stations spotted on RX and one G spotted my 2.5W FT8 TX.
UPDATE 2218z: 7 stations spotted today on 6m FT8 RX with the furthermost OZ5TG (738km). QRT now.
This photo, taken yesterday, was meant to be of the swans that you can hardly see! Still the trees are nice. 😁
"Why are you such a winger?
Having seen your comments about amateur TV it seems that you are just a prejudiced old fart that cannot accept that other amateur radio interests gain greater prominence than your stupid ideas on 40MHz propagation.
For a very long time I have held the view that these inexpensive modules could form the basis of a 70cm transceiver. Indeed somebody may hav...
