10m QRP FT8


At 1352z I switched from 10m WSPR and 8m FT8 to 10m QRP FT8.  On 10m WSPR and 8m FT8 I have had no spots all day. 

23 spots of me on 10m FT8 QRP TX mostly in the USA. On 10m FT8 RX, 131 spots, mostly from the USA. 

The photo shows some of the stations, mainly in the USA, that  spotted me. Considering it is just a few watts, quite a few!

The death of the UK Queen and the new King - NOT amateur radio

Whether or not you are a royalist, the UK queen worked very hard as head of state. She was well respected across the world. 

My own view is that nobody deserves respect or wealth just because of who you were born. Much wealth is based on slavery. This is wrong.

In the case of the queen she has dedicated her whole life to the service of the UK. She has earned respect. I hope King Charles III can similarly earn our respect. 

He has a hard act to follow. Initial signs are good.

70cm FT8 contest this evening

If things are normal, this evening is the 70cm FT8 activity contest. Activity is usually high. 

Even with the V2000 vertical or 2m big-wheel omni I usually copy PA and EI and manage a few QSOs. Normal FT8 QSOs are fine. No special contest software. Even if you don't enter a score, this is a good chance to find activity.

If you think 70cm is quiet, you are in for a shock! 

See https://www.rsgbcc.org/cgi-bin/contest_rules.pl?year=2022&contest=70cmsgmac. The RSGB contest starts at 1900z.

UPDATE 1958z:  I only stopped on for about 30 minutes, but despite 5W to the 2m omni big-wheel I was copied as far away as Devon. Had I been on longer I am pretty sure further would have been possible. 1 QSO was had and I was called by another but we did not complete. On RX, the furthermost was Cornwall and the Netherlands.

Last night's 70cm activity contest

Last night I was only on for 30 minutes. Conditions seemed a bit up, but after 30 minutes my voice had had enough. Also, I had probably worked all the stations that I was likely to with my 10W pep and 2m big-wheel omni antenna. In all, 5 stations were worked. The map shows the stations worked.

Amsterdam gables - NOT amateur radio


This is probably the last of the photos from our break in Amsterdam last week. It show the gables on the ends of buildings. There are loads of beautiful houses in the city.

We like the Netherlands very much. 

We have been there many times.

10m QRP WSPR (Wednesday)

 Since about 0930z I have been on 10m WSPR TX with my 500mW W5OLF beacon. No spots.

Change of plan - 8m QRP FT8 (Wednesday)

A change of plan. I decided to try QRP FT8 on 40.680 MHz right away. Rig turned on about 0930z. No spots after 6 minutes.

UPDATE 1106z:  No spots so far. Rig going off to cool.

10m FT8 RX

After breakfast I hope to be on 10m FT8 RX again. Yesterday was successful. If 10m FT8 is promising, I shall switch to 8m FT8 QRP TX and 10m WSPR. 

UPDATE 0942z:  Change of plan. See other posts.

Squirrel - NOT amateur radio

 


This was seen at Anglesey Abbey yesterday.

60m (5 MHz) allocations

Before I start, let me say my "outings" on 60m are rare. 

Speaking personally I find the UK allocations totally confusing. I would much prefer to have the WARC 15 kHz wide allocation instead. Many countries now have this. Using modes like WSPR and FT8, very little spectrum is needed. 

I know much of this is beyond our control, but I am sure a narrower contiguous band would be preferable to many, especially if this was a worldwide allocation.

Amsterdam - NOT amateur radio


We like the Netherlands. The people are friendly and, in many ways, like us. 

The photo shows a typical view of Amsterdam last week with bikes (lots!), canals and lovely houses. It is our 7th visit, so we must like it! 

I have also been to the Netherlands many times for work years ago.

10m FT8 (Tuesday)

Just before breakfast, I turned on 10m FT8 with the FT817ND. At 0817z, 8 stations have been received. I am not on TX at the moment.

UPDATE 0911z: 12 stations so far spotted on 10m FT8 RX today.

UPDATE 1251z:   Doh! Guess who forgot to turn on the PSU? Silly me, this meant the FT817ND worked until its batteries died.

UPDATE 1322z:
So far today (with the break!) 33 stations spotted on 10m FT8 RX.

UPDATE 2117z:
235 stations spotted. QRT soon.

Amsterdam breakfast


This was breakfast last week in Amsterdam. There seems to be a lack of fruit there, which surprised us. 

Sunspots - Tuesday September 13th 2022

10m QRP FT8

It is now 1555z and I have been on 10m FT8 for about 5 minutes. So far, just 2 G spots on RX.

UPDATE 1638z:  Pretty poor!  Just 4 Gs spotted on RX. Nobody has spotted me on TX.

UPDATE 1657z:   Just G0FWX (160km) has spotted me.

UPDATE 1912z:  8 stations spotted on RX with the furthermost ZS1AN (9742km).

UPDATE 2118z: QRT now. 26 stations spotted including Africa, South America, North America and Caribbean stations. 

Earth-electrode "antenna" in the ground

Until our son accidentally cut it, I used this antenna extensively from VLF to 60m. On 630m (472 kHz) it consistently got reports from Norway with a measured ERP  of just 10mW using WSPR. 

My theory is that at low frequencies it acts as a loop in the ground. As you go higher in frequency the loop gets smaller, so the antenna gets worse. 

If my theory is correct, the loop will get larger as frequency is lowered making it very effective for sub-10 kHz communications. Indeed, such an antenna has been used to great effect by DK2FC and others at VLF.

For use on LF and MF it has worked well for me.

Beginhof, Amsterdam - NOT amateur radio


This is a very secret and calming part of Amsterdam with an entrance that is quite obscure. 

Our "harvest" - NOT amateur radio

This year we grew pears, tomatoes, crab apples and beans as well as some herbs. 

Most of the tomatoes are still green. As you can see, this has not exactly been a bumper year. We had a wet winter and dry spring with a very hot summer. The pears were not bad (if a bit hard) and the crab apples just enough to half fill a small jar with crab apple jelly. Beans? Maybe enough for 1 meal. Tomatoes? If the green ones turn red I may have the same as a punnet from a supermarket. If they stay green I shall have a go at green tomato chutney. Overall, a disappointing "harvest".

10m QRP WSPR (Monday)

Again on 10m WSPR TX with 500mW QRP.  So far, only spots by local G4KPX (14km).

UPDATE 1215z:   Just G4KPX and HB9TMC (905km) spotted me.

8m FT8 QRP (Monday)

Very shortly, I shall be on 40.680 MHz FT8 TX again with my FT817ND and low wire dipole. 

There seem to be fewer monitors on 8m now that the main Es season has ended. Es still has some openings , but these are fewer now. Most openings now are random MS, F2 or aircraft reflections I suspect. 

Yesterday, EI9KP (649km) again spotted me on 8m. This is very unlikely to have been Es.

UPDATE 0950z:  On 8m FT8 now. Once the Cornish 8m beacon becomes active, I shall start monitoring it on PI4 mode.

UPDATE 1221z: No spots all day. Rig currently off cooling.

UPDATE 1415z: On TX again. EI9KP (649km) has again spotted me. I suspect EI9KP has spotted me nearly every day I have been on 8m!

Sunspots - Monday September 12th 2022

2m FT8 QRP (Sunday)

So far this evening I have been spotted by 16 stations (see map) and 1 QSO with a station in the west of Wales.

Milking - NOT amateur radio

The queen dying after so long as head of state is sad. We are certainly in a new age now. Whilst in Amsterdam last week every English language channel was about the queen and her long reign. 

When we got back home  yesterday, we had non-stop queen on the BBC. Now, I know people grieve in different ways and the BBC will have prepared for how it would respond. They probably have had recordings for this eventuality prepared for years and years.

Am I alone in believing there is grieving and their is milking? 

In my view, enough is enough. I would like to hear about other things as well in the world. Perhaps some of the news is dedicated to the queen and then other news is covered?

If I was an anchor person on the BBC, I would run out of things to say!

Ducks - NOT amateur radio


In Amsterdam last week we saw a shop selling nothing but rubber ducks for the bath. You could get quite a few famous people! 

10m WSPR RX (WISPY)


This was designed 10 years ago as a simple 10m WSPR RX. Later, with slight changes, this became the 10FT8R FT8 receiver that appeared in RadCom. 

The design is very simple and used low cost crystals either for WSPR or FT8 RX. It is a direct conversion RX so will also pick up signals on the other sideband. It is extremely unusual for this ever to be an issue. Lots of stations have been received.  

On a simple PCB, it would make a low cost, simple, and useful club project.

8m FT8 QRP (Sunday)

As I am home again, I am again on 8m FT8 QRP with the FT817ND and low wire dipole. No spots.

UPDATE 1207z: EI9KP (649km) has again spotted me. I wonder if this is aircraft reflection?

10m QRP WSPR TX (Sunday)

Now that I am back home, I am on 10m WSPR with my beacon and 500mW. 

UPDATE 1353z:  No spots of me all day.

UPDATE 1535z: Just a spot by FY5KE (7110km). This looks like F2.

UPDATE 2025z:  Seems like all the spots are now by F2 with the furthermost FR1GZ (9724km).

Cambridge Club - virtually

For the last few days I have been in Amsterdam. 

The Cambridge radio club (CDARC) held its first face-to-face meeting since the pandemic began (a builder's evening). As an experiment they ran a hybrid meeting with people attending in person as well as others by Zoom. 

I attended the whole thing from Amsterdam on my phone! The hybrid meeting was, in my opinion, a great success.

10m WSPR and 8m FT8 TX

 After a few days away, I hope to be on again tomorrow. Normal service should resume on Sunday.

Stamps and seals - NOT amateur radio


In the centre of Amsterdam is a shop selling stamps and seals. I have never seen such a shop before. 

160m FT8

 Many people think they can't go on 160m as they need huge antennas and extensive ground systems and/or their noise is very high. Using just QRP and my earth-electrode antenna in the ground on FT8, both North and South America have been widely copied on RX and I have worked all over Europe on TX . As FT8 needs only 50 Hz bandwidth provided by the free software, it works well with very weak signals much weaker than SSB or CW. If you have local noise then you can try FT8. 

UK Prime Ministers - NOT amateur radio


This will mean more to people in the UK than elsewhere in the world. It made me chuckle.

The Chinese are coming?


Several UK dealers have been advertising the new Chinese SDR portable (the Xiegu G106) that in many ways looks like a much better radio than the FT818 and far less expensive.

My main objection in the past to Chinese amateur radio products has been quality control and consistency. Maybe this is the first of a new breed? 

This radio is HF only, but look at the price!! 


OFCOM announces spectrum earmarked for the police in Northern Ireland - NOT amateur radio

 OFCOM has released some spectrum in the 700-900 MHz region for police use in Northern Ireland.

 Solar flux is 127 and the SSN 75.  A=19 and 4.

Sad news - NOT amateur radio


This cartoon was posted on FB earlier. Whatever your views on monarchy, the UK's Queen Elizabeth II was well respected across the world as a head of state. The new king will have a hard act to follow.

Rembrandt's Night Watch - NOT amateur radio

Today we went to the Rijksmuseum in Amsterdam to see the famous Night Watch by Rembrandt. We first saw this priceless painting many years ago when my younger son commented that the colouring in was not very good! He was very young at the time!
