As I have been away, I only returned to 8m WSPR TX under ISM rules (10mW ERP complying with IR2030) this afternoon. I am currently doing some local tests, although my dipole antenna is faulty and needs replacing. Until this is fixed I am not expecting to be copied.

10m 500uW WSPR (Friday)
As I have been away for a few days I have only just returned to QRPP 10m WSPR this afternoon. So far already 68 spots of me by EA8BFK (2880km).
6m F2?
When sunspot numbers and solar flux numbers are high, there is always a chance of the F2 MUF reaching 6m or even higher. I remember some years ago hearing 6m SSB stations from South Africa and the USA just like locals. At the time I just had a wire dipole.
Shrinkflation - NOT amateur radio
Instead of putting prices up just make things smaller and hope the consumer does not notice. Yesterday I bought a chocolate bar. In 1996 it was 62.5g. Now it is 51g. This happens with so many things.

HF propagation
At the moment, we are meant to be on the downward slope of cycle 25, although in the last few days, the solar flux and sunspot number have been very high. Even if sunspot numbers are declining, solar conditions will be good for several years.
One useful tool is https://prop.kc2g.com/ (see map) which shows how good the MUF is across the world.

8m monitors?
With my 8m station using only a low dipole, I suspect that stations need to be quite strong to be spotted here on FT8. Compared with the better stations with beams and more height, I guess I am probably 10dB down. On FT8 this means they will often spot stations I cannot.
Also, with the same power on 6m (2.5W), I can usually be spotted across England on 6m, whereas I struggle on 8m. One of the issues is there are too few people monitoring on 8m compared with 6m.
Nonetheless, I intend to experiment with 10mW ERP 8m WSPR this Es season as this will (hopefully!) show what is possible with a very simple system.
10mW ERP could be generated by a Raspberry PI, I think. It probably needs additional low pass filters to ensure compliance with IR2030. At this power everyone in the UK could have a go without a TX permit as long as ISM rules are followed. I cannot comment on the rules within the EU or elsewhere.

Low cost QRP SDR transceiver
Just over £193 pays for a 5W all mode SDR transceiver. You pay a little more for shipping. This is a lot less than an equivalent Japanese transceiver.
There is a shake-out coming. Expect the Japanese to be facing stiff competition from low cost manufacturers.
China may not be the source in the future as Chinese wages creep up and costs become higher. Canny manufacturers will be on the look-out for countries that can make things for less.
Once again this is via AliExpress.

Thank you - NOT amateur radio
On my blog is a link to buy me a virtual cup of coffee. This is entirely voluntary.
However, very many thanks to those that have donated. Any money generated will go towards future projects/research.
My wish is that you all have as much fun as I have had on your journey through the hobby. I have particularly enjoyed finding out new things and experimentation.
Two things : The journey is more important than the destination (learn from your mistakes) and you can have lots of fun without spending much.
Pixie transceivers
I have built versions for 80m amd 40m and had QSOs with each. With something this simple there are compromises. The RX, in some cases, lacks selectivity and can be overloaded by strong broadcast stations. Nonetheless they do work and they are hard to beat for the price.
The cheapest I have seen is £1.35, which is less than the price of just 1 part if bought in the UK!

How do they do it?
Both Ali-Express and the original manufacturer, I presume, make a profit!
I just cannot see how they do it. It is made in the Far East, shipped by air across the planet and easily cloned I am told.

8m ISM WSPR (Sunday)
Shortly, I shall be turning on my 10mW ERP 8m WSPR under ISM rules on 40.680MHz USB dial.
This means my QRPP WSPR will be about 1450Hz higher. I am not really expecting any spots as I have yet to sort out my antenna.
I shall ask locals to check I am getting out.
UPDATE 1436z: No spots.
10m 500uW (0.5mW) WSPR (Sunday)
My QRPP beacon has been re-synced to Internet time, but no spots yet.
UPDATE 1437z: EA8BFK (2880km) has spotted my 500uW 10m WSPR 10 times so far today.
70cm UKAC activity contest results
You would not exactly say I am a contest nerd. One thing is certain: guess who will never win! If I come half way up the table I'd be very pleased!
I like to submit an entry into the activity contest even though I stay on very little time, use 10W SSB and a 2m big-wheel omni antenna. In the low power section I am 43rd out of 70, which is not bad.

6m QRP FT8 (Saturday)
At about 1620z, I QSYed to 6m FT8. At 1630z, 4 stations had spotted my 2.5W FT8 to the V2000 vertical omni antenna.
UPDATE 1800z: 9 stations have spotted my QRP. On RX, the furthermost is EA9ABC (1873km) in North Africa.Knotted tree - NOT amateur radio
8m FT8 RX (Saturday)
Currently, I am monitoring 40.680MHz USB dial FT8.
UPDATE 1348z: No spots.
UPDATE 1621z: Locally I can see ZS1TX, ZS3/V51PJ and ZR1ADI were spotted but these did not appear on PSKreporter. For some reason, these spots were not uploaded.
10m QRPP 500uW WSPR (Saturday)
My 500uW (0.5mW) 10m WSPR has already been spotted multiple times this morning by EA8BFK (2880km). Perhaps this is not too surprising with the solar flux and sunspot numbers so good.
UPDATE 0948z: 12 spots already.
UPDATE 1808z: 34 spots of my 500uW QRPP WSPR, one with about 20dB in hand!! See table.
Ely last Thursday - NOT amateur radio
It is called "the Isle of Ely" as it is built on a rare hill in these parts.
Much of the Fens area is flat for miles. It is one of the most fertile areas in the UK.
630m QRP WSPR overnight
An average session with no real DX with my 10mW ERP from the earth-electrode "antenna" in the ground. 10 stations spotted me (see table) with a new reporter (I think) from Wales.
19 Apr 2024
630m QRP WSPR (Friday)
My 10mW ERP from the earth-electrode "antenna" in the ground was turned on at about 1810z. So far, spotted by one station.
UPDATE 2104z: 3 stations have spotted me.
OFCOM and DAB licences
OFCOM is inviting applications for small scale DAB multiplex licences. See the OFCOM website for further details.
8m FT8 receive (Friday)
This morning, I am on 40.680MHz FT8 receive. No spots at 1017z.

10m QRPP WSPR (Friday)
Already my 500uW (0.5mW) WSPR eacon has been spotted 8 time at 0908z by EA8BFK (2880km). See table.
With solar conditions promising, I wonder if I shall be spotted in the USA later?
UPDATE 1635z: 15 spots of my extreme 10m WSPR QRP so far.

8m FT8 RX
UPDATE 1642z: ZR1ADI (9777km) in South Africa was the only spot today. I guess this is TEP.
10m QRPP WSPR (Wednesday)
No luck yet today with my 500uW (0.5mW) 10m WSPR today.
Yesterday there were quite a few spots of my 500uW WSPR by EA8BFK (2880km). The impression I am getting is this ultra low power works on single hop F2 as long as things are settled, but multiple hop F2 is far harder. Based on these results, I am expecting European spots via Es later.
UPDATE 1545z: No spots today.
UPDATE 1618z: I spoke too soon! 3 spots late afternoon from the Canary Islands (again).
UPDATE 2050z: EA8 (probably F2) ,OE and DL (probably both Es?) spotted my 500uW QRPP WSPR. If these two were Es, this is probably the start of the Es season.

6m QRP FT8 (Tuesday)
My 2.5W FT8 to the V2000 vertical antenna is on, but just 5 English spots so far.
10m QRPP WSPR (Tuesday)
My 500uW (0.5mW) 10m WSPR beacon has been on all day. I suspect conditions are not good enough.
UPDATE 1354z: No spots.
630m QRP WSPR overnight
An average session last night with 8 stations spotting my 10mW ERP (measured) WSPR from the earth-electrode "antenna" in the ground with no DX.

What is reality? - NOT amateur radio
Recently I attended a University of the Third Age series of lectures given by an ex-professor at King's College, London.
One of the things he said was people had modelled how people see. Our brain "sees" an interpretation of reality. When fed with true reality, it led to societies collapsing!! Perhaps it is better not to see the whole truth!
10m 500uW WSPR (Monday)
As for the last few weeks, I am on 10m WSPR with my 500uW beacon. Yesterday was quite successful and conditions today look promising. No spots yet though.
UPDATE 1212z: 5 spots so far today.
630m QRP WSPR overnight
A very average session with no real DX. Just 8 stations spotting my 10mW ERP WSPR from the earth-electrode "antenna" in the ground with the furthest GM.

Western values? - NOT amateur radio
In the "west" we seem to value democracy, although the rich get richer and the poor poorer. Unfettered capitalism is overdone.
Yes, people cannot rely on hand-outs from a welfare society - they have to forge their own paths and work hard - but in my view, poorer people are getting a raw deal.
It is my view that the days of those of us in the "west" thinking we are always right are drawing to a close. I hope a fair and just world comes sooner rather than later.
All systems have faults, but let us get the best from each so that all of mankind can benefit.
70cm activity contest last Tuesday
My entry (never a winning score with just 2 QSOs, 10W, short period on air and a 2m omni antenna!) was submitted this morning.
It is my view that this 70cm UKAC is on the wane with fewer people active. The 70cm FT8 activity contest on the other hand is "humming". It looks like many people prefer FT8 to SSB these days. FT8 works with far weaker signals, but like so much these days, it has less human interaction.
We seem to becoming a society with far less human contact sadly.
Am I alone in thinking impersonal AI call centres are a pain? "Say in your own words what you are calling about". "You want to talk about xxx. Is that correct?". Say "yes" or "no". Actually I would rather speak with a human being!
Spring flowers - NOT amateur radio
6m QRP FT8 (Sunday)
My 2.5W to the V2000 vertical omni antenna was turned on at about 0755z. So far (at 0806z) 4 English stations spotting me.
UPDATE 1143z: 9 spots of my QRP including one from Germany.
UPDATE 1535z: 13 spots of my QRP 6m FT8 today (see map).
500uW 10m WSPR (Sunday)
My beacon (with the PA off) was turned on at about 0755z. I wonder if I shall be spotted in the USA today with QRPP?
UPDATE 0900z: Just a single spot by EA8BFK (2880km).
UPDATE 1548z: 9 spots only from the Canaries so far today (see table).

Without this man things would have been very different. I often wonder, say, if radio had been been discovered centuries earlier.

630m QRP WSPR (Saturday)
My 10mW ERP 630m WSPR (measured) was turned on at about 2020z. So far, just 2E0ILY/KIWI (209km) spotting me.
It is very disappointing to see I am the only UK station sending 630m WSPR according to WSPRnet at present.
17 different stations have spotted my 10mW ERP 630m WSPR in the last 2 weeks.
Spring is coming - NOT amateur radio
Trees are coming into leaf. It felt much warmer today on our walk around the village. It is windier.
8m dipole
As mentioned before, it looks like my 8m dipole antenna system has an intermittent fault. Recently, I decided to concentrate on 8m TX with ISM restrictions, which means 10mW ERP. WSPR gives me the best chance. I doubt 8m FT8 at 10mW ERP would be enough.
A reminder that, certainly in the UK, possibly elsewhere, under ISM rules 8m beaconing is licence free and open to all. A full T&I 8m TX permit costs £50 annually in the UK. With more countries opening the band for real amateur radio research, I keep my fingers crossed that radio amateurs will eventually be granted restricted access with conditions. I have long said that just 5kHz in the ISM band would do.
For 10mW ERP tests the antenna must be reliable.
The actual antenna and coax are not problems, whereas erection is more of an issue as this requires ladder work. I can probably manage OK as the ladder work is quite low, but I get giddy very easily these days so even a short distance off the ground is harder than it once was.
500uW 10m WSPR again
My 10m WSPR beacon, without the PA, is on again. At 0846z, no spots.
This QRPP is really great fun and definitely worth trying in the upcoming Es season. I suspect FT8 would not work.
UPDATE 1817z: 23 spots of me so far today. Please note that my beacon is pre-programmed to report 0.5W even though the power with the PA off is 30dB lower (500uW).
