Back lawn in June - NOT amateur radio
The rear lawn is still green, but starting to turn brown. It usually recovers in the autumn with dew and rain.
8m experiment (Monday)
Just EI9KP (649km) spotting me today. Certainly here, I am seeing no evidence of Es propagation from mainland Europe. The same is true of 10m. As I am spotted by EI9KP on 8m FT8 frequently, I am wondering if this really is Es?
Loose ends - NOT amateur radio
At the moment, I seem to be busy with loose ends.
Last week, we had my wife's 19th sibling reunion. Rather than take it in turns at our homes we went back to stay in an hotel in Barnsley, where they all grew up. It was a very successful get-together, but my wife said it was her last time in Barnsley. She also says she will never go to Devon again. I am compiling my legacy book of projects.
It looks like we are preparing for the worst! Any one of us could be dead tomorrow. On the other hand, we could live for many years. We just don't know.
The moral seems to be to live, and enjoy, every day as your last.

Often these are pheasants, but this unusual one of a cat made of thatch was seen recently.
The case for a small UK 8m amateur band
It is true to say that I am fuming by the attitude of OFCOM and the RSGB to a tiny 8m allocation. Let me explain.
OFCOM seems dead against an amateur allocation and the RSGB appears to just accept this. Our hobby is meant to be about self-training. In my personal experience of RF development, without any doubt the best RF engineers were those who were intrinsically motivated and "turned on" by RF. I have read countless CVs of electronics graduates who, frankly, were totally useless. I knew more at 16 than they did!! I learnt more from my RAE course than they did with a degree!
If we are really interested in future RF designers, we should be doing all we can to promote "self training".
These are my proposals:
- 40.680 - 40.685 MHz (5 kHz only). This is in the ISM band and widely used internationally
- Narrow digital only (e.g. WSPR, FT8, CW and no speech)
- By NoV only
- Strictly non-interference
- Power limited if need be.
OFCOM and RSGB, wake up!!

10m QRP WSPR TX
My 10m 500mW WSPR beacon was turned on at 0810z. Yesterday I got 7 unique station spots all in Europe by what I assume is Es. No spots yet today.
UPDATE 1656z: 32 unique stations have spotted me. This looks like a mixture of Es and F2.
8m experiment (Sunday)
My 8m QRP gear was turned on 40.680 MHz USB dial FT8 (first) TX at 0810z.
UPDATE 1153z: Spotted by 2 stations with 1 FT8 "QSO" with a station in Slovenia. As this is a simple exchange of reports and QTH, I am treating this as completely within the terms and spirit of my 8m licence. I want to know how my QRP signal in received in Slovenia. This is a perfect way.
UPDATE 1839z: Spotted 6 stations in 6 EU countries.

That book
This week I was in Yorkshire for my wife's sibling reunion, so progress on the book was limited. My new deadline is June 27th when I hope to go to Devon to see my brother for the first time since 2019. My wife is still at home.
So, the deadline is now June 27th before I leave. This time I am going by coach as the train may be unreliable. The book is coming on, but there was more work than I expected. In a way it is my legacy. I hope you have as much fun as I had.
Sheffield Station - NOT amateur radio
This week we went by train to Barnsley for our annual sibling reunion changing at Sheffield. We have met on 19 occasions.
Rybakov HF verticals
Some years ago I bought one from SRC in Wales. Although I believe this is no longer available, they all have one thing in common: the end of the antenna is a high impedance, so a transformer is needed to get the SWR into the range of auto ATUs found on modern rigs. Usually this is an UNUN built into the antenna.
In getting things together for my free PDF book, I realised this was absent from my website! This is now corrected. As mine had been unused in the back of the garage, I swapped mine for an active RX antenna that works well. The swap was with Jason M0NYW.
See https://sites.google.com/view/g3xbm4/home/antennas/x80_1 .
8m experiment (Saturday)
As usual, I am on 40.680 MHz USB dial QRP FT8. Already spotted very strongly by EA3ERE (1153km) in northern Spain.
My usual pattern is to be on for about one hour. let the rig thoroughly cool and then come on again afterwards. It would seem Es allows modest QRP stations, like mine, to enjoy the fun.
It is now about 0931z.
UPDATE 1230: Still just EA3ERE spotting me and nobody spotted here. Now QRT as the rig cools.
Sporadic-E (Es)
We are currently at the peak of the Es season in the northern hemisphere. Yesterday 14 stations spotted me on 10m WSPR TX. All these look like they were by Es. My reports on 8m FT8 also look like Es. By the end of the summer the Es season will be over.
The Es season usually lasts from April to August. The peak months are May, June and July. However Es can occur at any time. There is usually a much smaller peak just after Christmas.

Normality - NOT amateur radio
Every June a local village holds a Gilbert and Sullivan performance in a barn. With Covid-19, this was not possible, so this was the first production since 2019. It was great to return to normal. They did "The Mikado".
Young birds - NOT amateur radio
This is the season for nests and young birds. Yet again, we have some house sparrows nesting in our roof (they were there last year too) and we have dunnocks, robins, blackbirds, pigeons, collared doves and goldfinches nesting in our hedges or very nearby. There are probably others as well. This young thrush (I think) was being fed on our back lawn.
8m experiment (Friday)
Later this morning, I expect to be on 8m QRP FT8 TX on 40.680 MHz USB dial (first).
UPDATE 1016z : No spots given or received.
10m WSPR QRP TX (Friday)
Yesterday I was spotted by 22 stations on 10m WSPR despite only going on after 1600z.
Today I expect to be on again with 500mW from the W5OLF beacon.
UPDATE 1013z : 4 unique stations spotting me today so far.
Rallies
The following rallies are due to take place this weekend. As always, please check with the organisers before travelling any distance.
Saturday June 18th - Bangor and District ARS. Contact Andrew 07980846272.
Sunday June 19th - East Suffolk Wireless Revival. Kevin 0771 0046846.

FY5KE 10m WSPR reports
Some time ago I queried if my WSPR reports by FY5KE in South America were just by a European pirate. Yesterday I had an email and these reports look like they were genuine. I get these reports quite often.
8m experiment (Thursday)
All being well, I should be home again later this afternoon. I intend to be on 8m TX on 40.680 MHz USB dial FT8 then.
UPDATE 2111z: Spots of my QRP 8m TX by 2 stations and I have spotted 2 stations here. 1 station in Slovenia "worked". Oops sorry exchanged FT8 reports and locations, sorry OFCOM!! Silly me thinking UK stations engaged in self training and research could be worked. My hand slapped!! 😉😉
Catch them young
This was 2010 when I had "help" in the back of the garage from my grandson. Sadly I didn't manage to get him interested in electronics: his main passion is ringing church bells. See his YouTube videos under Ringer Luke.

Barnsley - NOT amateur radio
We're having our 19th sibling reunion in which my wife gets together with her 2 brothers. In the past, we have taken it in turns to meet in each others homes. This year we are staying in an hotel in Barnsley which used to be their home.
Finningley optical transceiver
This was built in June 2013, but because of my stroke it was not used. With 100mm lenses, it has a range of at least 65km. This was my only SMA project.
Memory costs - NOT amateur radio
It is amazing how far memory has come. Not many years ago we were amazed by CF cards with 1GB of memory. These days you can get 512GB on a micro SD card. I think you can even get 1TB micro SD. In 10 years time I wonder what will be the norm?

Guess who forgot?
Last Sunday was the annual PW QRP contest that I totally forgot!! The 2m and 70cm UKAC contests I set alarms for, but this one was overlooked. Doh!!
8m experiment (Tuesday)
Yesterday my QRP TX on 40.680 MHz USB dial FT8 was spotted by 4 stations. I am unlikely to be active for the next few days.
10m WSPR (Tuesday)
Yesterday was fairly quiet here on 10m WSPR TX with just 14 stations spotting my 500mW QRP. Most of these were via Es.
13 Jun 2022
Propagation mode?
Both yesterday and the day before, I had over 70 reports of my 500mW 10m WSPR beacon. Today I have had just a few reports and these could be by F2. Es can be very localised with strong signals somewhere and nothing a few kilometres away.
On 8m I am frequently spotted by EI9KP (649km). This happens so often that I suspect some other form of propagation other than F2 or Es is involved such as random meteors or aircraft scatter.
The period of FT8 makes me think random meteors or aircraft unlikely. It is far too far to EI9KP for tropo.
Am I missing something?
OFCOM
OFCOM has updated the data it holds and has proposed a new licencing regime for commercial drones. See the OFCOM website for details.
Beans - NOT amateur radio
However, I surprised myself last year with good crops of tomatoes, crab apples and runner beans. The secret seems to be to ensure the soil has plenty of goodness in it. This year, I have put beans in the same spot as last year (having added lots of goodness to the soil first) as well a 4 bean plants in a pot. I shall grow some lettuce and tomatoes shortly.
If I get as many as last year, I shall be pleased.
8m FT8 TX (Monday)
Yesterday I got my first report from a station in Scotland bringing my country count to 10.
This proves that even a very simple station can give useful results, although those with much higher ERP are achieving some remarkable results.
Later today I expect to be on 8m TX again.
UPDATE 0816z: On 40.680 MHz USB dial (first) FT8 now.
Shetland - NOT amateur radio
This photo was on 365project recently. It shows a sunny day in the Shetland Islands in Scotland. Normally, it is windy and cold this far north! At one time, these northern islands belonged to Norway.
10m WSPR QRP TX (Monday)
Yesterday 76 stations spotted my 500mW QRP 10m WSPR. I think these were Es. Later today, I expect to be on again.
UPDATE 0822z: On 10m QRP WSPR TX now. Already 2 spots of my QRP from EA8BFK (2880km) in the Canary Is. This could be F2 propagation.
UPDATE 0828z: I am wondering if the very first spots from EA8BFK were with the PA off, so at sub 1mW level? When the PA is first turned on there is usually about 20 minutes of drift. I have just turned the PA off to see if I get spots!
UPDATE 1116z: Having got no spots from the Canary Is since the PA was turned off, I think it unlikely EA8BFK was spotting me on extremely low power. Since turning the PA on again, I am again getting lots of spots.

10m WSPR QRP TX (Sunday)
Yesterday was one of my best days ever on 10m WSPR TX with over 70 stations spotting my 500mW 10m WSPR beacon.
At the moment, I am on 10m WSPR TX using 500mW to the tiny W5OLF beacon. No spots yet today.
UPDATE 1943z: 74 stations spotting my 500mW WSPR today with the furthermost FR1GZ (9724km). Most were by Es. This is even more than yesterday.
Where our grandson rang this morning - NOT amateur radio
8m experiment (Sunday)
It is now 1032z I have been on 8m FT8 TX on 40.680 MHz USB dial for about 30 minutes.
UPDATE 1712z: 4 stations have spotted my QRP today with the furthermost EA8BFK (2881km) in the Canary Is. Also, G4APB (88km) spotted on RX, I think for the first time on 8m FT8; at -22dB S/N he was marginal here. I have lost count of all the stations now spotted on 8m FT8, but they are in 5 countries. We could do with a few more countries active on TX.

2m halfwave antennas
Most people opt for 5/8th wave antennas when they want better ranges on their 2m handhelds. Some years ago now I made a half-wave antenna for 2m. It was widely used on my many 2m rigs. It was first used in the 1970s, so must be about 50 years old!
The idea was simple: the end is a high impedance so I just added a tuned circuit tapped at the 50 ohm point to match to the rig. It got me across the English Channel with a 10mW AM handheld (160km), so it must work! The antenna was actually on the Fredbox.
Clearly this would work on 70cm if scaled.
One photo shows the matching arrangement and the other the full whip.
10m QRP WSPR TX (Saturday)
At the moment (1040z) I am on 10m WSPR TX with 500mW from the W5OLF beacon. 14 stations have spotted me by Es already! Another good Es day.
