Dalham - NOT amateur radio

This village, not far from us, is filled with thatched cottages. One was on the blog recently. It is a good place for a walk. The church is some way from the village...next door to the manor house!

UPDATE 1537z: We went for a walk at Dalham earlier. Delightful.

Sunspots - Sunday February 26th 2023

 Solar flux is 152 and the SSN 129.  A=10 and K=2.

QDX on 10m

It has arrived and is tiny!! 

Stations that spotted my QDX
this afternoon on FT8

It has been tried out on 10m WSPR and FT8 and seems to work fine. I have already been spotted in the USA on FT8 and heaps of stations in the USA on WSPR.  Impressive!!

UPDATE 1850z:  18 stations have spotted me on 10m FT8 TX and 250 stations spotted me on 10m FT8 RX with the QDX.

Stations spotted on 20m FT8 RX
  this evening on the QDX

UPDATE 2208z: 101 stations spotted on 20m FT8 RX with the QDX on FT8.  QRT now.

Primroses - NOT amateur radio

Over winter, we plant primroses, which usually are out all winter adding a splash of colour. This winter, they were slow to appear, but have now all flowered.  

Luckily, Muntjac don't like these!

10FT8R 10m FT8 RX

We are a few weeks away from the main Es season in the northern hemisphere. F2 propagation on 10m is very good again.

Often there is a need to monitor 10m FT8 without using the "big rig". You might like to consider my 10FT8R 10m FT8 RX. This is simple, works very well and is low cost. Mine never got beyond the breadboard stage (as you can see)!

See https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/10ft8r-rx .

Plans for Saturday

 Later, I hope to go on 10m FT8.

Muntjac - NOT amateur radio

Several times recently I have been in the back garden and disturbed a Mutjac deer. These are dog sized deer that were imported in the 1800s. They eat lots of flowers! This one was testing some fat for the birds!

See https://en.wikipedia.org/wiki/Muntjac .

Sunspots - Saturday February 25th 2023

 Solar flux is 164 and the SSN 130. A=6 and K=2.

8m QRP FT8 (Friday)

 It is now 0920z and I have been on for about an hour. So far, no spots.

UPDATE 0955z:  No spots. I shall turn things on 8m off TX shortly, but on later in case there is any transatlantic F2.

UPDATE 1251z: Spotted by MCP44 (47km).

10m WSPR QRP (Friday)

My 500mW WSPR TX beacon was turned on at 0805z. So far today, no spots. 

UPDATE 0921z:  17 spots of my QRP so far from the Canary Is.

UPDATE 1300z:  8 unique stations have spotted me today, mostly from the USA.

Plans for today (Friday)

At the moment my plan is to go on 10m WSPR TX and 8m QRP FT8. Depending on  my QDX coming, I may try this. 

UPDATE 1211z:  My built QDX is supposed to have arrived at Castle Donnington in the night. It is meant to be delivered here by 1800z.

Bellringing - NOT amateur radio

Bellringing is an art that has been around in the UK for many centuries. At the moment they are trying to encourage new ringers so every church tower in England can be rung on the day of the Coronation in May. Our grandson has been ringing for several years and has a YouTube channel. Here he is ringing at Foxton recently.

Sunspots - Friday February 24th 2023

Solar flux is 148 and the SSN 108. A=22 and K=1.

Rather them than me! - NOT amateur radio

 This video of a hiking "path" in Switzerland is sure to raise your blood pressure.

10m QRP WSPR (Thursday)

 Almost forgot! When on 8m FT8, I can go on 10m QRP WSPR TX with the 500mW beacon as the antenna is available. So for about 10 minutes (it is now 1327z) 6 stations have already spotted me.

UPDATE 1644z: Quite a few spots of my 500mW WSPR from the USA.

8m QRP FT8 (Thursday)

At about 1318z, I QSYed to 8m QRP FT8.  So far, just one spot by FG8OG (6670km). It seems transatlantic reception even of my QRP is almost daily.

UPDATE 1534z: 2 spots of my QRP (again) from the Caribbean. It feels like this is most days. I may try WSPR another day. At 1W on the FT817ND I wonder how this will be?

Rally

This rally has been notified to me. Always worth checking the details are correct before travelling a long way!

Sunday Feb 26th  - West Manchester Radio Club Red, Leigh, WN7 2PJ. 

I have also received news that the Callington (CARS) Rally in Cornwall in March has been cancelled.

10m QRP FT8 (Thursday)

For a change, I am on 10m FT8 with 1W from the FT817ND. After about 20 minutes, 8 spots of my 1W and 42 spots of others.

Stations spotted on 10m FT8 RX today

UPDATE 1025z: 1 QSO, 11 unique stations have spotted me and I have spotted 88 stations.

UPDATE 1106z:  2 QSOs and 108 stations have been spotted on 10m FT8 RX today. At a guess, I would guess the FT8 10m activity is at least 4 times higher than on WSPR.

Unique stations spotting me on 10m FT8 TX at 1300z

UPDATE 1315z:  3 QSOs and 22 stations have spotted my 1W FT8.  On RX, 214 stations have spotted me.

Sunspots - Thursday February 23rd 2022

 Solar flux is 152 and the SSN 100.  A=6 and K=3.

South Devon - NOT amateur radio

The photo shows the view looking from Slapton towards Start Point. 

QDX transceiver

There was a good review of this in a recent QST. Mine is still showing as "being collected". QDX is a QRP, multi-band HF digital transceiver available as a kit or ready built from QRP Labs. It looks like these come from the west of Turkey.

See https://www.qrp-labs.com/images/qdx/QST_QDX_Review.pdf

Shack

Since moving to this QTH nearly 10 years ago (doesn't time fly?) I have a dedicated shack. 

SSB and FM operation require me to be in the shack, whereas FT8 and WSPR may be monitored on a different PC in the lounge. 

I usually sync to internet time early morning (just using Windows 10) and I can pop in the shack (which I do often) in seconds.  Although I sometimes re-sync later in the day, I am not convinced this is really needed.

Although I have a separate bench for building, my poor fine motor skills mean it is rarely used these days, sadly.

The photo shows me looking at birds in the garden as the shack probably has the best view.

Oscar 100 narrowband

My most recent peek at this geosynchronous satellite last night was worse than last time! Activity was pathetic. My most recent look was at 2220z on a Wednesday evening. There were just 2 stations only active. 

My only recommendation is just don't bother. By now, I was expecting it to be busy, whereas it is seriously under-used. As mentioned before, people (well a few) enjoy the challenge of getting active, then lose interest. 

My own view is this is just too hard for the "appliance operators" of today. If one of the big manufacturers offered a rig (they won't as Japan and the USA are outside the footprint of the satellite), things would be different as "black box" operators could chat with much of the world without big beams and linears and with a small, fixed antenna. Don't tell them they can do this for free on the Internet!😀

What will happen? Things will carry on as now and activity might pick up as solar activity wanes. What is needed is a low cost add-on to enable appliance operators to get on the satellite using their main rig.

People happily shell out huge amounts for linears, beams and towers. None of these would be needed.

Crouching down - NOT amateur radio

 

One of the issues with getting old is crouching down. If you get down, it is hard to get up! However, we have an answer - grandsons! At their age they have no problems with hips or knees, so we ask them to take a photo. Problem solved.

Old pals - NOT amateur radio

We have known these friends since university days in the 1960s. My wife and I are in yellow.

This was at nearby Anglesey Abbey with a complete stranger kindly taking the photo.

Simple regen RX

Quite often I get asked how simple can you make a receiver that gives useful results. 

Of course the simplest of all is a crystal set that does not even need a battery. 

The simplest circuit that really works well is probably the one shown. I even adapted this into a 1 FET 80m transceiver. The RX works well on AM, SSB and CW.  By changing the tuned circuit, it will work on different bands. As a transceiver my main issue was netting the RX onto the TX frequency.

There are plenty of similar circuits on the Internet.

10m QRP WSPR TX (Wednesday)

Testing with the 500mW beacon started at about 0940z. It is now 1000z and, so far, 2 unique stations spotting me. No surprises.

UPDATE 1019z: 4 unique stations spotting me.

UPDATE 1420z: 13 unique stations have spotted my QRP today.

UPDATE 1621z: 19 unique stations have spotted me today. Certainly the station in the Canary Is could have copied me on microwatts at times if his noise floor was low enough. Pretty sure than 10mW ERP 8m WSPR (legal, I think, in the UK without a licence in the ISM band for beacons) could reach surprising distances at times.

8m QRP FT8 ( Wednesday)

 Testing began at about 0940z. No spots yet today.

UPDATE 1414z: It seems "crossing the pond" is almost daily at the moment on 8m FT8, even though the ERP is about 1W when the rig get hot!! Just spotted by FG8OJ (6670km). 

UPDATE 2142z:   On 8m FT8 RX today my system spotted G9PUV and EI2IP.  I am surprised that I do not copy many more. At some point, I need to check the 8m sensitivity. This would involve a trip to a nearby amateur with a calibrated signal generator. It would not surprise me if it was several dB deaf on 8m. Even so, I have still copied S.Africans and Caribbean stations several times.

SPRAT back issues

All the back issues of SPRAT are available on a flash drive. It is cheaper for GQRP club members. It is very low cost and well worth it. There are years of projects on it. Look for "SPRAT on a stick". 

Many times I have said that if all magazines had to go, SPRAT would be my last. This is incredible value.

Tulips - NOT amateur radio

These are colourful flowers in the spring. Sometimes they are floppy and an aspirin in the water makes them stand up again. I have no idea why! My wife likes flowers in the house.

QDX coming

This morning, I had an email from QRP Labs and the carrier saying that my QDX is on its way. It is due this week. It covers 20-10m at 5W FT8.

See https://qrp-labs.com/qdx.html .

UK winter 1947 - NOT amateur radio

The winter of 1947 was very harsh. This is a photo of my cousins outside their house. Some years later we lived a few houses down. In Salcombe, snow is rare.

8m QRP FT8 (Tuesday)

Been on 8m FT8 early (since just before breakfast). So far, no spots today.

UPDATE 0955z:   Still no spots. OFCOM has confirmed that my new T&I 8m licence has all I asked for.

UPDATE 1639z:  7 stations have spotted my QRP 8m FT8 today with 4 being in the Caribbean. It seems that if the F2 MUF is high enough, I get spotted across the Atlantic even with QRP.   At one time to be spotted "across the pond" was magic on 8m, whereas now it seems quite commonplace.

10m 500mW WSPR TX (Tuesday)

My 500mW 10m WSPR beacon was turned on before breakfast. It is now 0912z and all the usual reports including many from the Canary Isles, which I assume is F2 propagation.

UPDATE  1658z:  So far today, my 500mW WSPR has been spotted by 19 unique stations with the furthermost WA2N (6488km).

UPDATE 1837z:   22 unique stations have spotted my 500mW 10m WSPR today.

Sunspots - Tuesday February 21st 2023

Solar flux is 160 and the SSN 135. A=8 and K=3. 

Woke - NOT amateur radio

Today I heard that Puffin books is sanitising Roald Dahl books so that they do not cause offence. Now, he was far from an angel, but kids love his books and do not need wrapping in cotton wool. 

In my view, the world is going stark staring mad!! 

Should we pull down the pyramids because they were built by slaves? Should many UK country houses be pulled down because money was made by slaves workers in the West Indies? Many street names in big cities were named after slave merchants.

I am all for a fair world, but where does this end? 

Anglesey Abbey - NOT amateur radio

This path at nearby Anglesey Abbey is lined with snowdrops. On the trees, buds are appearing. It can turn much colder, but there are signs of spring all around.

New T&I 8m TX permit approved

Just heard from OFCOM that they have approved my T&I 8m permit for when mine runs out in April. I have asked for a provisional copy to check over. Assuming this is OK, it means I have broadly the same as currently until April 2024.

10m 500mW WSPR TX (Monday)

It is now 0950z and I have been on since 0900z. Spots of me by a local and from the Canary Isles.

UPDATE 0959z:   4 unique stations spotting me now. Most are probably via F2.
