Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

472kHz WSPR
Although the "season" is really well over, I decided to give 472kHz WSPR (10mW ERP, 20% TX) with the earth-electrode "antenna" in the ground a go overnight. So far only G1GKN (99km) has been spotted.
FT4
Although release candidate versions of WSJT-X have been released including FT4, I think I shall now wait for the fully released version before installing. FT4 sounds like a useful Es mode with its shorter periods. It is not quite as sensitive, but with Es signals are often strong even with QRP.

Colourful Cambridge - NOT amateur radio
Well, the centre of Cambridge is certainly entertaining! As well as the float in the photo we had buskers singing classical opera, which was very good (people applauded).
The downside is there are more homeless people now in the city. Some are definitely genuine (often with mental health issues) and some see Cambridge as a good hunting ground with plenty of visitors. These days we prefer to give directly to a homeless charity so we know the money will not be squandered on drugs.

No early 6m Es today
So far on 6m FT8 RX just a single station spotted HB9SJE (795km). Little sign yet of Es on the band.
UPDATE 1819z: Just 3 stations spotted all day today on 6m FT8 RX. Pathetic!

Grandchildren - NOT amateur radio
Over the half-term holiday we have seen all 4 of our young grandchildren.
Today, our "London" grandchildren arrived for a few days. The photo shows them with my wife in our garden room.
Mess, but clean mess 😊

Currency oscillations - NOT amateur radio
At the moment the UK pound is up and down against major currencies. With BREXIT uncertainties and the likelihood of a new Prime Minister in the next month or so, this is hardly surprising. I guess the fact the UK pound has not tumbled dramatically is good news.
The UK must be the laughing stock of the world! How can we be so divided? I am struggling to see how rifts created in the last few years will be healed. Healed they must be.

FT991A fan
Nobody gave me the answer I needed! Is the FT991A fan temperature controlled? Does it only come on when the rig gets hot? I think the IC7300 fan is always on when on TX. If I was to buy an FT991A it would mostly be used at QRP powers.
Julian G4ILO
Although a SK for several years now, I still get people coming to this blog via Julian's site. This is a fitting tribute to his memory. Although we never met "on the air", I considered him a good friend. Like many, I followed his struggle to the end. RIP. You are not forgotten.
6m Es
As is usual at this time of year, I am on 6m FT8 RX. So far today, 71 stations in 10 countries spotted, mostly by Es and all European.
UPDATE 1350z: Now 230 stations spotted on 6m FT8 RX today with best DX TA8A (3331km).
UPDATE 1520z: Now 232 stations spotted on 6m FT8 today in 22 countries. Plenty of 6m Es!
UPDATE 2034z: Now 244 stations spotted. Unless things suddenly change I suspect this is it for today.

First car - NOT amateur radio
We bought our first car in 1971. It was sold for scrap for £40 in 1978 as I recall. It was a Morris 1000. No radio, no aircon, very basic back then! We were quite sad when it went. It was bought by a local agricultural mechanic who did it up and had 2 more years on the road. The photo shows the day we sold it.
BREXIT - NOT amateur radio
My dad who died in 1987 had a phrase, "they couldn't organise a piss-up in a brewery". In his own colourful language, I think this sums up our attempts to reach a BREXIT deal before we leave the EU. Certainly the Conservative ruling party under Theresa May has made a total disaster of this. I'd like to think the main opposition Labour party would have done better, but somehow I doubt this.
We are now in a leadership contest to elect a new Conservative leader and Prime Minister. Whatever happens next, the UK remains deeply divided both in the country and in parliament.
I wish we had some answers. If anything I suspect we will be even worse after a new leader is elected. If we have a public referendum the outcome is likely to be far from clear cut. What then?

That new radio
Steve G1KQH has been encouraging me to buy a new radio. Any new radio would have to include 160m, 10m and 6m. Bands like 2m and 70cm would be useful. If the radio has a fan, it would have to be quiet.
I was holding back just in case Yaesu announced a real replacement to the FT817 at Dayton. Neither Yaesu nor ICOM made any great announcements of new products of interest to QRPers like me sadly.
At the moment I am warming to the FT991A. The IC7300 is probably the better radio, and is SDR based, but I gather the fan is always on and some can be noisy. Yes there is a mod, but I am in danger of invalidating any warranty. The rig would be used at 10W most of the time, so a fan that comes on only when the PA is warm would be good. At the moment, there is a 3 year warranty with Yaesu and cash back on some models. Having had many Yaesu rigs over the years, I am pretty happy with this supplier. Knowing me, this rig would have to last for years!
If anyone has any strong opinions against the FT991A I'd like to hear them. As my voice is not too good these days, FT8 and WSPR would probably be the main modes used.
Specific questions about the FT991A. If the answer is in the manual, I cannot find it! Does the fan come on only when the radio is hot? If I run mainly QRP will I hear the fan?

USAF strength - NOT amateur radio
We live close to Lakenheath and Mildenhall airbases. I am not sure what was going on, but a few moments ago there was a big plane being escorted by smaller planes and helicopters. They made quite a noise as they went overhead, so much so that I had to look. I thought Trump was coming to the UK later. Perhaps this was a dress rehearsal.
Waitrose - NOT amateur radio
For some reason, my wife likes shopping at Waitrose, which is a food chain and part of John Lewis and Partners. I have several issues with Waitrose. Firstly I find this chain expensive. Secondly, I think they need to do more work to use recyclable or compostable packaging. Some packets can be recycled and some cannot. As a major UK food retailer, I think they should tell their suppliers or the business will go elsewhere. They have the power and they should use it!
Today when we went shopping there it was very quiet. The low cost free range eggs were, conveniently, out of stock. Instead if you wanted free range eggs you had to pay far more. I expect the free coffee and paper will soon, quietly, go.
If you ask me I think they are in deep trouble. It would not surprise me if lots of stores were forced to close or John Lewis as a whole goes under. I may be wrong but in Newmarket, where we go, there is competition coming soon from a low cost supplier and that will really hit them.
The next few years will be make or break. At the moment, they depend on customer loyalty, but this is wearing thin. Old ladies die and young people want better value, so they shop around or buy online.

More from Chelsea Flower Show - NOT amateur radio
It seems hard to believe we went to the Chelsea Flower Show a whole week ago. This is the most important flower show in the UK. Although we went on an RHS members' day, it was very busy.
As I mentioned before (at least I think I did!) we had our tickets as a present for our 70th birthdays late last year.

Irish 8m band activity
Although there are a very few beacons operational around 40MHz, very few countries have an amateur band at 8m. I have lobbied the RSGB for a small slot to be negotiated, although, not too surprisingly, nothing has come of this. Being mid way between 10m and 6m it is an ideal band of Es and MS experiments. Even 100kHz and 10W would be useful to advance radio science. OFCOM has managed to find 2MHz for DATV work and I cannot believe they cannot allocate a small slot for serious work around 40MHz! No standard comercial gear is available for this band, so it would only attract serious experimenters, not "black box" operators. So, the number of people using such a band in the UK would be small.
I quite like the Irish model of allocating wide chunks of under-used spectrum to amateurs. If they were not pen pushers it would be good for OFCOM to allow use of any spectrum on a strictly "non-interference" basis, even if the power was strictly limited. Sadly, I cannot see this happening. It needs people policing this and this costs money rather than generates money! Also, you have to understand RF. I may be forgiven for thinking few now have this skill.
Meanwhile in Eire, one of the few countries to allocate spectrum at 40MHz to amateurs, work and QSOs continue.

Garden of England - NOT amateur radio
Over the weekend we spent a few days with our "Kent" family and grandkids. We saw some places we'd not been to before with our son. The collage shows a typical Kent oast house (for drying hops) as well as several views of our younger grandson. Kent is known as "the garden of England".
6m FT8 RX in the last day
Stations spotted here since mid-afternoon
yesterday on 6m FT8 RX on the FT817 and V2000 vertical
|
Last evening, I copied my first transatlantic station this season J69DS (6840km) on St Lucia in the Caribbean. My antenna is still the V2000 vertical omni.
UPDATE 1445z: 60 stations in 10 countries so far spotted on 6m FT8 RX in the last 12 hours. Plenty of Es about on 6m.
UPDATE 1821z: Now 154 stations in 21 countries spotted on 6m FT8 RX in the last 12 hours. Will there be any Caribbean or North Americans later on 6m FT8 RX?
UPDATE 1922z: Much to my surprise a single 15 second 6m FT8 CQ was responded to by an Italian. A subsequent series of 2.5W CQs was copied by 26 stations!
UPDATE 2137z: So far 248 stations spotted on 6m FT8 RX in the last 12 hours. No "real" DX. Mostly single hop Es.

MLS cashback on Yaesu
Certainly MLS (and probably other dealers) are still offering cashback on certain Yaesu products. The next few weeks looks a good time to buy. Unless I am mistaken dealers are offering 3 years warranty on Yaesu.

Yesterday, we were with our son and family in Kent. They enjoyed climbing over the ruins of this old church at Reculver by the coast. In the photo you can just see our son trying to take a photo of his children.
6m FT8 - amazing
Although we have only been home for 30 minutes, my 6m FT8 2.5W to the omni vertical was spotted by 18 stations all over Europe and I have spotted 47 stations in 12 countries. Most of these were Es.
UPDATE 1514z: Now 108 stations spotted on 6m FT8 in the last hour or so with best DX EA8ACW (2988km).

Meteor showers
Southgate News has details of an upcoming meteor shower. At peak times the ionised trails support brief VHF propagation. Random meteors support such propagation but openings are far less frequent.

Early 6m Es again
When I looked earlier there was widespread Es on 6m at 0845z, which is early. I can't wait until the band really opens up to long distance E layer DX.
Most July JAs come through to western Europe on 6m. I have a theory this is due to mesospheric E layer ionisation due to noctilucent clouds that form at this time of the year.

Talk - NOT amateur radio
We are fortunate to live right next door to a 200 year old windmill and local museum, which is one of the best in the UK.
Every spring and autumn they hold talks of local interest. The photo shows the presenter in free flow. It was a good, interesting and well attended talk.

EU elections - NOT amateur radio
Because of our delayed departure, the UK has had to take part in EU elections, The results will be known on Sunday when all EU member countries have voted.
In the UK these elections are quite odd. Unless by some late change of circumstances we vote to stay EU members, those elected will only sit for a few months.
It seem likely that the 2 major UK parties will do badly to either right wing or parties favouring staying members of the EU community. In the UK, this will be more of a protest vote. My wife and I have already voted Lib-Dem which is the party wishing to stay members. If I am honest none of the main UK political parties have policies which totally reflect my views, although the Lib-Dems are closest.
As a result of these elections, it would not surprise me if the EU made changes. With right wing parties on the rise, I suspect we will hear more about nations and less about a federal Europe in future. Assuming we do leave, I suspect the EU we leave will be much different within 5 years and we will wish we'd stayed.

Who is looking? - NOT amateur radio

160m FT8
At about 2012z I QSYed to 160m FT8. My 2.5W CQ was spotted by no-one at all and on 160m FT8 RX 8 stations in 7 countries spotted so far, all EU. As before, using the earth-electrode "antenna" in the ground. This seems to match and work well at 160m. In the "DX season" plenty of transatlantic DX has been spotted on 160m FT8. Best DX this evening, so far, is UT9EZ (2471km).
UPDATE 2149z: Now 38 stations in 12 countries spotted tonight on 160m FT8 RX. All EU. Best DX remains the UT9.

BREXIT - NOT amateur radio
Whatever your views on BREXIT are we can all agree on one thing: we have made a right mess of it! The UK people and main parties are deeply divided over this and the UK is more "broken" now than for years. The Prime Minister is going soon, but I cannot see a good replacement.
I have the feeling that we are on the verge of a new time in UK politics as both the Conservative and Labour parties are deeply divided over BREXIT.
What is needed is something to unite the UK. Short of war, I do not know would fit the bill - maybe we will all "get real" about climate change. Remember how public opinion suddenly changed on plastics?

Southgate News has a link to photos of the Dayton Hamvention in the USA. Although still to check, I don't think I missed big announcements from the Japanese companies. The photos again confirm this is (mainly) a male hobby. I suspect that "old" men are less likely to attend. Of course, Elecraft made big play of their new K4 transceiver.

2m FT8 RX
At the moment I am still on 2m FT8 RX, although I may try 6m FT8 later. So far today, just 6 stations spotted with best DX G0RQL (353km) in Devon.
UPDATE 1220z: So far today 15 stations spotted in 3 countries.

2m FT8
At about 1930z I QSYed to 2m FT8 calling CQ (2.5W to big-wheel omni) initially. Now I am RX only. Although no QSOs resulted from the CQ calls I was spotted by 10 stations with best DX GW0KAX (279km). On RX best DX spotted is PD0PVL (378km).
UPDATE 2122z: Now 11 stations in 3 countries spotted this evening on 2m FT8 RX.

Going backwards? - NOT amateur radio
Many things seem to get worse over time, not better.
We once had a bus every 30 minutes into Cambridge. It has been every hour now for several years. The store M&S in the UK used to be the place to buy underwear: quality was good. These days they are clearly made to a price and quality is poorer. My wife bought a coat and bag several years ago, but the replacements have fewer pockets. We used to get vouchers from Tesco, but these have stopped. Every few months we used to get vouchers for a free coffee and cake from John Lewis, a well respected UK retailer. I just noticed the voucher is for a free cake when you buy a drink. I am sure many will not have noticed this change.
Now I know retailers are having a hard time, but this John Lewis change was sneaked in, hoping many would not notice. The coffee at John Lewis is expensive, so the voucher will not get used.
I can think of plenty of examples of things getting worse.

6m FT8
This morning I am again on 6m FT8. Initially I called CQ (2.5W to the omni vertical) with no QSOs resulting, although my best spot was by M0BEW (194km). On 6m FT8 RX my best DX is LA3DV (1022km).
UPDATE 1006z: Now 16 stations spotted in 2 countries so far today on 6m FT8 RX. Mostly Gs.
UPDATE 1250z: Now 27 stations in 7 countries spotted on 6m FT8 RX today.

160m FT8 RX
Overnight I was again on 160m FT8 RX using the earth-electrode "antenna" in the ground. Plenty of Europeans spotted, but nothing from "across the pond". I spotted one station that was supposed to be in Iran, but I think this was a German station with the wrong QTH locator!
160m FT8 RX here overnight |
Sunspots - Monday May 20th 2019
Solar flux is 68 and the sunspot number 0. It looks like the less active side of the sun has rotated to face us again. I guess we are unlikely to see more spots for a few weeks. A=3 and K=3.
19 May 2019
160m FT8
A few minutes ago I switched to 160m FT8 using the earth-electrode "antenna" in the ground. Initially I called CQ (2.5W) whereas now I am RX only. So far, no spots given or received.
UPDATE 2000z: So far just 2 stations spotted. Best DX is SP2MEF (1297km). End of season?
UPDATE 2027z: 14 stations spotted so far this evening. Now it is getting dark all Europe is coming through.

Still not much new at Dayton
Although I have not seen the final day summary, there would appear to be little new announced by the "big boys". Yes Elecraft announced the K4, but I have heard nothing from the traditional Japanese manufacturers.
Next year? Actually it would not entirely surprise me if at least one of these "pulls the plug" on amateur radio before May 2020.

6m FT8
Because of my laziness, I remained on 6m FT8 RX overnight. If I remember I may try 160m FT8 RX tonight.
So far this morning, 22 stations in 5 countries spotted on 6m FT8 RX in the last 6 hours with the best DX being OZ4ACK (881km).
UPDATE 1604z: 55 stations so far spotted in the last 12 hours on 6m FT8 with the best DX being YO8SSB (1874km).
UPDATE 1920z: Now 66 stations spotted today on 6m FT8 RX with best DX EA8TR (2989km).
UPDATE 1954z: A brief 2.5W CQ to the vertical omni antenna on 6m FT8 was spotted by 5 stations with best being EA7DL (1643km)

Oscar 100 - people losing interest?
One local amateur who put together 2.4GHz and 10GHz gear for Oscar 100 has now had enough fun and is instead converting it to a /P station for terrestrial activity sessions. I wonder if this is a trend?
People enjoy the challenge briefly, have a few weeks of fun, then say bye bye. By now I was expecting the satellite to be very busy, but it is not. As they say, "the journey is more important than the destination".
Perhaps for appliance operators it is too much of a challenge - you need to be keen to get a station together and a fat cheque book does not work.

Dayton Hamvention 2019. Few new products?
First reports from Dayton are disappointing with few new products announced. As the years progress, it would not surprise me if some Japanese companies leave the amateur radio market, or even go bust. In many countries it is an "old mans" hobby with fewer buyers, so a diminishing market. Some are clearly struggling already.

Post holiday blues - NOT amateur radio
Having just returned from a great holiday in Portugal we have the usual problems. Empty fridge, long grass, loads of washing and lots of post. To cap it all it is now raining and my 10m, 20m and 40m end-fed antenna has fallen down! Ho hum! I managed to cut the front lawn, but not the back.

472kHz WSPR overnight
17 May 2019
Back home and back on 472kHz WSPR
At about 2110z we arrived back home. I am back on 10mW ERP (20%) WSPR on 472kHz. A new station has appeared - G6ECH (227km). As yet, no spots of me.
Portugal castle - NOT amateur radio
Today is our last day in Portugal. We have seen some amazing sites and met some lovely people. Yesterday we visited Beja, which is supposed to have the highest tower in Portugal.

Portugal - NOT amateur radio
We get home tomorrow after a great trip. My wife made this collage, which sums up our trip quite well.
This has been a busy few days, but we have seen and learned a lot.
For days we have been looking for bee eaters. Today my wife and I saw 4!

Right wing extremists - NOT amateur radio
The upcoming European elections will be test for the far right parties in many EU countries. Although fairly centralist politically myself, there is no denying that politics in many countries is moving further right.
Many of those who vote right wing are disaffected people who think (falsely) that right wing parties will bring back halcyon days without immigrants and the EU. In my view all EU nations have changed forever and people are being misguided.
The UK and USA have been integrating immigrant people for a very long time. It is important that people coming into a country learn the language and integrate. It is very unlikely those who do not try to fully integrate will feel welcomed.
If right wing parties do well in the EU elections the EU could change radically in the years ahead.

Even lower!
Stefan DK7FC has been doing experiments at even lower frequencies! This was posted a few days ago. His attachment has NOT been included.
"Hello SLF freinds,
Just a note from a recent experiment at 270.1 Hz.
On sunday morning, 2019-05-12_10:34,+150m, i've done a carrier transmission on my ground loop antenna again. I did not expect more than, hopefully, a detectable spectrum peak in 57.6 km distance, i.e. at my tree site. The tree receiver site was listening and recording data using vlf-rx tools.
One E field antenna and two orthogonal loops were listening. The loops have been improved recently! They consist out of a single circular turn of 1.2 m diameter using 10mm diameter copper tube (about 25 mm^2). It is a closed loop, non-resonated, with an impedance matching transformer. This transformer previously had 1:100 turns. Now it (they) has 2:240 turns, i.e. two turns primary (out of 14mm^2, AWG6). This improved the sensitivity below 2 kHz significantly ( abt. 4...5 dB).
Furthermore the TX antenna length and angle has been improved, resulting in about +3 dB more signal strength on the RX site!
In a previous experiment at 270.1 Hz, some month ago, there was no result at all, not the weakest trace, despite excessive tweaking of all parameters. So the question was, will the improvements result in a detectable signal now?
Several things went wrong in that experiment. I forgot a bag containing important equipment such as the power supply for the netbook that generates the carrier signal. Also the output power was not as high as planned, just about 380 W, giving 2.2 A antenna current (I measured 64.7 V at 1 A DC). Anyway i managed to improvise so the experiment was started, but with some hours of delay which meant i higher QRN background level. Then, on the WLAN link to the tree, there were several interruptions of the stream (i'll move to 5 GHz very soon!). I even got some QRM from my battery charger for some short time periods (forgot to disable the charger remotely). So there were several factors that could have been improved or avoided. And the middle of May is not the ideal time anyway.
Well, 270.1 Hz, that's the 1110 km band! The far field begins at 177 km distance, i.e. i am clearly in the near field here. Thus, from a 'magnetic' TX antenna, we would expect that the signal is mainly detectable on the H field, i.e. the loop antennas.
The first interesting results is that this expection is actually confirmed. There is nothing detectable on the E field but the carrier S/N in the H fields is close to 10 dB in the first run. Mixing the H fields and tweaking the filters rises the carrier S/N to 10.7 dB, see attachment.
So far not really an undoubtly detection but it is a candidate for optimism! With a few less problems during the experiment there is a chance for 14 dB SNR. Also, there is quite much sideband QRM arround 300 Hz which makes 270 Hz a bit harder to work on.

Portugal Birds - NOT amateur radio
Bird spotting in Portugal continues. As well as masses of storks today I spotted cattle egrets and a grey shrike as well as lots I could not identify. I was hoping to spot a bee-eater, but no luck so far. I've seen them in Spain before, so was hoping to catch at least one here.

70cm activity contest this evening
Starting at 1900z (8pm UK clock time) is the May leg of the RSGB's 70cm UKAC activity contest. SSB activity is better than usual and even 5W to a 2m halo usually gets me QSOs up to over 100km.
Lisbon trams - NOT amateur radio

Solar Cycle 25 predictions
This is getting more like BREXIT everyday with major disagreements amongst the "experts".
They all seem to agree that the size of the next solar peak will be similar to the last one, but there are major disagreements about the depth and length of the preceding minimum.

Digital mode FT8 has become enormously popular. Apparently a new release candidate of the faster FT4 is due out in a few weeks. I have yet to try FT4.

Mobile phones and driving - NOT amateur radio
Some of you may remember that one of my sons lost a brother-in-law in 2017 when he was ploughed down by a driver who went through a red light in Australia. It took him 5 weeks to die. He was in his late 20s.
Never, ever use your mobile phone whilst driving. Even hands-free can be distracting. If you can, put the phone in a glove compartment! I was appalled to see this video. I hope he was banned from driving for years and was sacked by the owners of the lorry. Stay safe.

Amateur radio antennas
When abroad on holidays I do a very sad thing. I count the number of HF and VHF beams I spot. In the USA and South Africa I spotted quite a few. So far in Portugal I have seen none. Well, I did say "sad"!
Angry sky - NOT amateur radio
We are on holiday in Portugal. So far, we have had lots of rain, although it is already much sunnier and drier. Tomorrow is expected to be warm (24deg C) and sunny.

Yaesu's flagship
Although far more than I am willing to pay for amateur radio gear, Yaesu is trying hard with their new flagship, SDR based radio called the FTdx101D being demonstrated at Nevada according to Southgate News.
I hope they introduce a real FT817 replacement later this year, SDR based. We should know next week.
If they "miss the boat" again, I give them 5 years or less before they quit this market. Of late, they have been followers rather than leaders. It is almost as if they have lost their way and are in "catch-up" mode. Over the years I have been a keen Yaesu man and it pains me to say this. If I was to say who might survive, my money is on ICOM.
