10m 500uW WSPR (Friday)
Although my beacon has been on all morning and synced to internet time, no spots of me today. I have lost count of the countries that have spotted my 500uW (0.5mW) 10m WSPR.

Rally News
The following rally has been notified to me. As always, I recommend contacting the organiser to check details.
Sunday June 2nd - Spalding and District ARS Annual Rally, Spalding, PE12 6AF. Contact rally2024@sdars.org.uk .
6m QRP FT8 (Thursday)
Today, I am on 6m FT8 with 2.5W to the V2000 omni vertical antenna. At 1400z, 33 stations had spotted me. Most look like Es.
UPDATE 1517z: 40 spots of my QRP 6m FT8 today so far (see map).
Brunch in Cambridge - NOT amateur radio
Google Adsense - NOT amateur radio
Perhaps they should rename this Google Nonesense? In the last hour my visitor numbers have (supposedly) doubled, which I am sure is not correct. I look regularly, although I am not sure why. Like the UK weather, I think your guess is as good!
European Es (Thursday)
As yesterday, there is intense Es in eastern Europe, which I hope moves west. Unlike yesterday, I have not seen any Japanese stations on 6m FT8. My own 2.5W FT8 is being spotted in the UK, with many on 6m hoping for some Far East DX!

Salcombe, Devon - NOT amateur radio
This photo shows where I lived as a young child. At the time we just took it for granted. Salcombe is in the distance on the left.
Much later, I realised just how lovely it was. These days it is a very expensive place to live with many second homes. House prices are ridiculously high, so much so that locals are priced out.
2200m beacon
As I recall it produced about 8W although the ERP was in the microwatts as my antennas were not very good.
29 May 2024
6m FT8 on 2.5W (Wednesday)
At about 1916z, I decided to go on 6m FT8 with QRO (for me!) of 2.5W. Lots of Es around Europe.
The furthermost was a spot of me by PY2DS (9583km) in Brazil. This looks like Es linking with TEP. On 6m FT8 RX loads of stations in Brazil spotted.
Pretty sure this is the third time I have reached South America on 6m in the last few weeks. One was with just with 10mW!
UPDATE 2117z: 115 stations have spotted me so far. Es in Europe seems to be good. My gear will be on overnight hoping that I might be spotted in the USA.
2m QRP FT8 (Wednesday)
2m Es (Wednesday)
Es on 2m is rare. I see that 2m Es is occurring in the east of Europe. Maybe it will spread further west?
See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .
6m 10mW FT8 (Wednesday)
10m 500uW WSPR (Wednesday)
My 500uW beacon is synced to internet time and on again. No spots at 0837z.
UPDATE 2055z: 2 stations in Europe have spotted my 500uW 10m WSPR.
Far East on 6m
It is believed this propagation is linked to noctilucent clouds which form usually in June and July. With climate change these seem to be more common.

630m QRP WSPR overnight
Not a bad session. It would appear spots are still being received from the old favourites, although I have not had DX spots now for a while.

6m 10mW FT8 (Tuesday)
UPDATE 1034z: My 10mW spotted by 4 stations mainly in the Baltic area.
Strong Es in eastern Europe (Tuesday)
At the moment I can see strong Es in eastern Europe. Let's hope it moves further west.

10m 500uW WSPR
My 500uW 10m WSPR was spotted by DK6UG (633km) late yesterday. This looks like a patch of Es.
160m QRP FT8 overnight with the earth-electrodes in the ground
27 May 2024
Recent events in the UK - NOT amateur radio
Several recent events have severely dented my confidence in "the deep state". These include the contaminated blood scandal, Grenfell Tower and the Post Office scandal. Time and again, we hear of corruption in high places. It makes me sick.
It would be good if those in high places operated at all times with high integrity and honesty. It would appear many cannot be trusted sadly.
160m QRP FT8 tonight?
Overnight, I may give 160m FT8 a go with my earth-electrode "antenna" in the ground. This assumes the match is acceptable.
For a first try I shall probably use 2.5W. It is unlikely I shall be on until it gets dark. I don't think I have tried 160m FT8.
UPDATE 1656z: The match is good and I am on 160m with 2.5W FT8. No spots on RX or TX.
UPDATE 1831z: One UK spot of me by 2E0INH (60km).
UPDATE 1900z: 3 UK spots of me so far this evening. Still very much light. Furthermost is G4BRK (133km). This is quite reasonable with 2.5W FT8.
UPDATE 2039z: 6 spots of me (see map).
630m QRPP WSPR overnight
Well, either the internet was not working here from the shack or there was an issue with WSPRnet. Although I was spotting DX on 630m WSPR and was sending all night, no spots at all. I shall probably try again tonight.
26 May 2024
Is there a problem with WSPRnet?
At the moment I am on 630m WSPR with my usual 10mW ERP. I am seeing no spots on RX or TX. This could be that I cannot connect to the internet or there’s a problem with WSPRnet. I shall leave it on overnight.

500uW 10m WSPR (Sunday)
Quite surprised to see my 500uW QRPP 10m WSPR had been spotted this morning by GM4WJA (624km). I suspect this is Es as I have been spotted in N.Ireland when I was running just 10mW FT8 on 6m.
6m 10mW FT8 (Sunday)
My 10mW 6m FT8 to the V2000 vertical omni antenna is on, but no spots at 0858z.
UPDATE 0950z: Spotted by GI0OTC (560km) in Northern Ireland. I suspect this is Es as I have also been spotted running just 500uW in Scotland on 10m WSPR.
UPDATE 1459z: No more spots of me on 10mW 6m FT8 surprisingly. No further Es reports of my QRPP. Perhaps later?
UPDATE 1735z: Some Es now. 4 spots of my 10mW 6m FT8 so far.
Es (Sunday)
At the moment Es looks quite promising in Eastern Europe. Let's hope this spreads west.

6m 10mW FT8 in the Es season
At the start of the Es season, I started with 10mW 6m WSPR. It worked, so I changed to 6m 10mW FT8, which in theory needs a better S/N to decode.
Every day, 10mW 6m FT8 has been very successful. Some reports suggest some margin too.
I think the fact that FT8 only needs a 15 second TX period compared with 120 seconds for WSPR helps to catch very brief Es openings.
When I return to 8m, I think I shall try 10mW ERP FT8 instead of WSPR.
23cm activity session
Well over a year ago I bought a 2W 23cms transverter that I intended to use /P in the 23cm activity sessions. As it has been so wet, I have yet to do this. Perhaps later?
I was only going to go out very locally, but on higher ground.
10m 500uW (0.5mW) WSPR (Saturday)
My 500uW 10m QRPP WSPR beacon was turned on at about 0830z. European Es looks quite promising, so I am hopeful.
See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .
UPDATE 1117z: No spots.
UPDATE 1738z: Just a single spot of my QRPP by DK6UG (633km).

UPDATE 1026z: 5 spots of my 10mW 6m FT8.
UPDATE 1731z: 10 stations have spotted me.
630m QRP WSPR overnight
Last night I went on 630m WSPR with my 10mW ERP. In all, 7 stations spotted me, which was better than I was expecting. Best DX was GM3YXM (425km).

630m QRP WSPR (Friday)
My 630m 10mW ERP WSPR from the earth-electrode "antenna" in the ground was turned on at about 2040z.
UPDATE 2115z: 2 stations have spotted me so far this evening.
500uW 10m WSPR (Friday)
My beacon is on and sync'd to internet time. No spots.
UPDATE 1839z: 2 spots in Germany of my 500uW WSPR. A reminder that my WSPR beacon is hard programmed to report 0.5W even though with the PA turned off it is actually 500uW only. I think these German spots were the first in several days.
European Es
At the moment European Es does not look too great although things can quickly change.
See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/.
630m WSPR overnight
For a change I went on 630m WSPR overnight with my 10mW ERP from the earth electrode “antenna” in the ground. In all, 7 stations spotted me. This was more than I expected. No real DX.
23 May 2024
630m QRP WSPR (Thursday)
For a change, I am again on 630m WSPR with my 10mW ERP from my earth-electrode "antenna" in the ground.
UPDATE 1908z: So far, just spots by G8OCV/SDR.
Puzzled
At the moment, I remain puzzled: at 10mW I was surprised that FT8 worked at all on 6m. Already today (presumably by Es) 10 stations have spotted me on 6m FT8 at 10mW.
At 13dB weaker my 10m WSPR at 500uW remains unspotted. I had assumed that signals 13dB weaker might have been harder, but then WSPR works with signals considerably weaker than FT8.
Probably Jan OZ9QV is correct, that the far shorter TX period for FT8 (about 15 seconds) catches very brief Es bursts with FT8 that the 120 seconds needed for WSPR does not decode: the Es cloud has to remain around for longer. Perhaps Es just bubbles up for very short periods more than we thought. Maybe FT4 would be better still, even though it is even less sensitive?
With FT8 I am pleasantly surprised how well just 10mW works with 6m FT8. Of course the WSPR signal at 500uW is more likely to be buried in noise too. Overall, I suspect the briefness of FT8 must help more than I was expecting.

6m 10mW FT8 (Thursday)
Once again, I am on 6m FT8 with 10mW and the V2000 vertical omni antenna. So far, no spots.
UPDATE 1220z: 8 spots so far.Greenpeace and a multinational oil giant - NOT amateur radio
This morning, I received a WhatsApp message from a friend urging me to sign a petition.
Sadly, these days I get very paranoid about links thinking the link could be a virus or bot being installed. If you are unsure of a link never, ever click it. Check that it is genuine by some other way if in any doubt. Often scammers try to work on your better nature trying to oblige a friend. A common one is "are you in this video?".
In this case I think it was genuine about a multi-billion pound profit multinational oil giant suing Greenpeace. Deep state gone mad again.

10m 500uW (0.5mW) WSPR (Wednesday)
My beacon has been on all day. No spots all day.
If I had good results on 6m FT8 with 10mW, I would have expected some Es spots with 500uW on 10m WSPR. Perhaps the 13dB difference takes signals into the noise floor?
That famous plaque - NOT amateur radio
6m 10mW FT8 (Wednesday)
My 10mW 6m FT8 was on overnight. To my great surprise stations in Norway and Finland spotted me in the middle of the night. To be spotted at all at this time is remarkable, but with just a few milliwatts took me totally by surprise.
UPDATE 1046z: Spotted in Poland with my 10mW 6m FT8.

Few new radios at Hamvention 2024?
Apart from the hint about the ICOM X60, I have not heard rumours of new radios on the horizon from the likes of Yaesu and Kenwood. If my thoughts are correct (I hope I am wrong!) both these are having thoughts of getting out of the amateur radio market.
Personally, it is my view that Yaesu has lost its way. Nearly a quarter of a century after the launch of the FT817 the world is still waiting!! Personally I think they have, sadly, missed the boat again.

10m 500uW WSPR (Tuesday)
Once again, my 500uW 10m WSPR is turned on although I am not too hopeful.
UPDATE 1410z: No spots today.
The pattern seems to be that 500uW is not quite enough for most people most of the time. I guess many have a background noise floor that has to be exceeded. It is also possible there are fewer people on WSPR these days. I would have expected ŧo see far more WSPR spots by Es.
6m 10mW FT8 (Tuesday)
Once again, I am on 6m with 10mW FT8. Unless things improve, I am not too hopeful.
UPDATE 1356z: Just 2 spots of my 10mW 6m FT8 today from Portugal.
European Es
Looking at the maps of Es reports, it would seem, at the moment. that Es is not as good as the last few days. As with all things sporadic E (Es), things can quickly change.

10m 500uW WSPR (Monday)
Although my 500uW (0.5mW) 10m WSPR beacon has been on all day, I am surprised to not get any spots. On 6m FT8 I have had lots of spots with 10mW. I shall try a re-sync.
UPDATE 1808z: No spots all day.
UPDATE 1851z: OE3GBB (1233km) has spotted my QRPP.
8m experiments
Experiments at 6m (as opposed to 8m) have FAR exceeded what I expected and convinced me that 8m WSPR at 10mW ERP would definitely be spotted by Es. The fact that 10mW FT8 on 6m reached Brazil yesterday was amazing with an omni antenna.
I may try 8m FT8 at 10mW ERP as soon as my 8m antenna is mended. At this rate, it would not surprise me if this spanned Europe as well. Judging by results at 6m, it certainly should. The only difference is the dipole, which is a bit lower in height than the V2000 used on 6m. I would expect this to (maybe) make a few dBs difference.
630m QRP WSPR
For the first time in months I was not on 630m QRP WSPR, when I was at home, last night. Gradually, the number of spots I had received had been dropping off. I shall be back on in the autumn and may try occasionally in the coming months, but not every night.
A new night-time challenge calls! I am still undecided what form this should take.
