2m FT8

After a brief look in on our local 2m FM gateway, I have returned to 2m FT8 calling CQ just now with 2.5W to the big-wheel. 5 spots so far with the best report being by GD3YEO (384km) on the Isle of Man. On 2m FT8 RX no spots yet.

2m FT8 never fails to amaze me: if I worked the Isle of Man with QRP CW or SSB I would be flabbergasted. To do this regularly, irrespective of conditions with 2.5W and just the omni antenna is just mind-blowing.

UPDATE 1857z: A recent 2.5W FT8 CQ was spotted by a couple of stations.

Antipodial 2m DX

Not quite sure how he finds all this juicy news, but EI7GL's blog reports some remarkable 2m DX QSOs in Australia and New Zealand.

This is a good blog with lots of interesting stuff regularly.

Kitchen narcissi - NOT amateur radio

I thought it was last week, but on reflection it must have been the week before, my wife bought a bowl of narcissi for the kitchen table. Most are now in flower.

It is great fun seeing them develop when we eat breakfast. The heads are smaller than we expected, but they still are glorious.

472kHz WSPR TX (10mW ERP) overnight

Although there were no stations in Norway spotting me, last night was quite a good session with 20 different stations spotting me on 472kHz WSPR despite me using the 10mW ERP from the earth-electrode "antenna" in the ground. At the moment, the 472kHz WSPR is still on, although I may switch to 2m FT8 later.

UK winters - NOT amateur radio

Although we had a few flutters of snow on this day a couple of years ago, most winters in England are just dull. The photo show our local baker and butcher on a typical winter day.

Sunspots - Tuesday December 10th 2019

Solar flux is 71 and the SSN 0. A=4 and K=1.

472kHz WSPR TX

For the first time in a while, I am back on 472kHz WSPR TX with 10mW ERP from the earth-electrode "antenna" in the ground. In the first few transmissions 7 stations spotted me in 2 countries, which is a promising start. No great DX as yet, but I'll leave it running overnight.

UPDATE 2125z: 12 unique spots so far.

UPDATE 2226z: 16 unique spots in 6 countries so far this evening.

AM QSO party - Jan 2020

Southgate News reports on an upcoming AM activity contest towards the end of January. On some bands there is plenty of space for AM. This concentrates on HF AM.  There is little doubt that SSB is a better DX mode and takes up less bandwidth, but there is still a place for AM.

East Cambs 2m FM net

At 8pm local time on Mondays we hold a net on 144.575MHz FM vertical. We normally stay on for less than 30 minutes and the technical discussions are pretty basic. Anyone in the area is free to call in.

Later, I might try 630m (472kHz) WSPR TX.

Roses - NOT amateur radio

This photo was taken last April when the roses at nearby Anglesey Abbey had not quite come out. Now they have just about all gone. Come next summer, these beds will be a mass of colour.

OFCOM and shared spectrum licences

OFCOM is inviting applications from professional users for shared spectrum at microwave frequencies.  These are shared shortish range services, ideal for local area networks in, for example, farms and factories.

See their website for details.

2m FT8

It would appear there are few stations on 2m FT8 this morning. A recent 10W FT8 2m CQ has been widely spotted with best DX DF6PW (562km). On RX nothing yet spotted.

UPDATE 1114z: Although just 2 stations spotted on 2m FT8 RX, I have been spotted by 11 stations in 4 countries with best DX spot being by EI2FG (565km).  One G QSO as a result of the CQ.

UPDATE 1435z: A recent 2m FT8 10W CQ was spotted by 10 stations in 5 countries.

UPDATE  1633z: A 2m FT8 CQ (10W to the big wheel) just now was spotted by 9 stations in 4 countries. In the last day 36 stations in 7 countries spotted on 2m FT8 RX.

UPDATE 1851z: Now 38 stations in 8 countries spotted today on 2m FT8 RX.

UPDATE 1938z: A recent 10W FT8 2m CQ was spotted by 11 stations in 6 countries.

Sunspots - Monday December 9th 2019

Solar flux is 72 and and the SSN still 0.  A=3 and K=1.

Sunspots often return for a few days as the more active side of the sun faces us. As we have had a considerable period with no sunspots, I wonder if we are really at the very bottom of the cycle? If so, we can wait for the climb to soon start.  It may a while, but as they say, "the only way is up".  It certainly cannot get any worse!

South Devon - NOT amateur radio

As a child until university days, I lived in South Devon in an area called "The South Hams".  Arguably this is one of the best parts of England.  Even now, I still feel drawn. The photo shows Soar Mill Cove, which is a few miles from where I lived.

UK General Election, December 12th - NOT amateur radio

On December 12th 2019, the UK has a General Election.

The ruling government is campaigning mostly on BREXIT. The outcome is anyone's guess. The opinion polls show the ruling Conservatives consistently in front, but whether they get a clear majority is far from certain. A hung parliament might get us a softer EU exit eventually,  but many in the UK are now sick and tired of delay, with many wanting this over and done with. The trouble is all major parties promise a lot, but rarely deliver. The UK Prime Minister is not trusted by many.

With just a few days to go, I have no idea who to vote for and I am sure very many others are also confused.

IC-705

Many people are following the European and USA release of this new radio from ICOM with great interest. At the moment the price and availability are not known. The release date in Japan was April 2020 I believe.  I try to update my website as I get new data. Personally, I think they would be stupid to release this without at least the option of an internal auto-ATU.

Austalian super-DX on 70cm

EI7GL reports that the 70cm record has been extended (2806km) in Australia. The contact was using FT8.

See https://ei7gl.blogspot.com/2019/12/australian-70cms-digital-record.html

2m FT8

In the last few hours 7 stations spotted in 3 countries on 2m FT8 RX with best DX being EI3KD (583km). Antenna is the big-wheel omni.

UPDATE 1219z:  21 stations in 6 countries spotted so far today on 2m FT8 RX.

UPDATE 1415z:  29 stations in 6 countries spotted so far today.

UPDATE 1455z: A recent 2m FT8 CQ was spotted by 9 stations in 2 ires.countries (no QSOs) with the best DX being G8WXV (277km).

UPDATE 1642z: Now 34 stations in 6 countries spotted.

UPDATE  1820z: A recent 10W 2m FT8 CQ was spotted by 9 stations in 4 countries including Eire and Germany. Again, the antenna was the big-wheel omni.  No QSOs resulted though. On 2m FT8 RX 40 stations in 9 countries so far spotted today.

UPDATE 1950z: A recent CQ was spotted by 8 stations in 4 countries.

UPDATE 2038z: The map shows the stations spotted so far on 2m FT8 RX today.


SAQ - Dec 24th transmission

The heritage VLF alternator transmitter on 17.2kHz CW in Sweden has a special transmission on December 24th. See their website for more details. Somewhere I have a QSL card for a transmission some years ago. You amy want to consider this PC receiver. It works very well.

2m FT8

Stations that spotted me this afternoon on 2m FT8 RX
Just now I called CQ on 2m FT8 with about 10W to the big-wheel omni. In all, 31 stations spotted me with the best DX report being by S51AT (1251km). Judging by the strong report (0dB S/N) from a couple of Slovenians, I think this was aircraft scatter.

On RX 40 stations spotted on 2m FT8 with best DX being YT5DEY (1752km). Again signal report suggests aircraft scatter.

UPDATE 2339z: At bedtime 66 stations spotted on 2m FT8 RX. As you will see below from Jan, he thinks my DX may be MS or winter Es.

Burwell, Cambs, UK - NOT amateur radio

Since 1975, we have lived in this East Cambridgeshire village. It is about 10 miles from Cambridge, 4 miles from Newmarket, 17 miles from Bury-St-Edmunds and 12 miles from Ely. In recent years the population has soared to about 6500. When we came it was about 4000. Luckily, it still feels like a friendly village.

The village has a fine church (see photo) and fully restored 200 year old windmill, the latter being part of one of the best local museums in the whole UK.

See https://en.wikipedia.org/wiki/Burwell,_Cambridgeshire

Lesser Chirpy (10m)

At the moment, at the depths of sunspot minimum, 10m is not exactly busy! In the late spring and summer 10m can be very good for Es communications up to around 1500km. Often, much further can be reached with 10m Es. Es can be effective at any part of the solar cycle.

Years ago, when 10m was good, I designed the Lesser Chirpy ultra-simple 10m transceiver. Like all simple transceivers, it is a compromise, but it is fun.

In the Es season it is capable of decent QSOs e.g. from the UK into Europe. In decent F2 conditions (may be a few years off yet) it should be possible to cross the Atlantic with it. The main limitation is the RX. Only TX if you know the frequency is clear.

Oscar 100

From time to time I look at the webSDR at Goonhilly in Cornwall monitoring the narrowband transponder of this geosynchronous satellite. This is a very unscientific look at activity levels, which must vary a lot depending on the day and time of day. Nonetheless, it provides a snapshot of activity levels.

As far as I can tell, it is beginning to get a bit busier, approaching levels I might have expected. The last time I looked (albeit a weekend morning) there were 10 stations on SSB. This is more than I have observed in the past, suggesting more people are becoming active. By now, I was expecting the narrowband section to be full. Even now, there is plenty of space.

SDRs and amateur radio

Southgate News has a piece about the impact of SDR on our hobby, mentioning that it will soon be possible to buy a 3.5GHz transceiver for about £50. As the piece says, we live in exciting times.

Trinity Street, Cambridge - NOT amateur radio

On my way to my relativity course in Cambridge, I walked down this street, Trinity Street. This is one of the most famous streets in Cambridge. About 200m behind me is Kings College Chapel.

Day off

As I have my U3A course on relativity in Cambridge on Fridays, I am not active currently.

Websites - NOT amateur radio

Being fairly sedentary these days, I tend to do things that I can do from home. I created and maintain several websites and blogs not all amateur radio related. One of these is for my wife's choir www.cambschoral.org.uk . Others are mainly amateur radio related.

Choose your sweets - NOT amateur radio

To be honest, I am not a great sweet addict. If I never had another sweet in my life it would not be a disaster.

My wife noticed this machine in a Cambridge supermarket. It allows you to fill a tin with the sweets you like. I did not even notice the machine!

2m SSB in the 1970s

When I first started in VHF amateur radio it was in the early 1970s, when most rigs were AM. Gradually people started using FM gear and this mode really took off with the coming of repeaters.

My first 2m SSB rig was a Liner-2. It was a revelation, with distances I could only dream about being workable even with very simple antennas. Nowadays many prefer the "rubber stamp" FT8 QSOs. Back in those early days 2m DXing was real fun and ranges of several hundred kilometres were possible most nights on SSB.

Delta-T - NOT amateur radio

Delta-T is a company in our village focusing on plant measurement gear and environmental science. They work from offices that were originally built in the 1500s. At one time they were a worker's co-operative although I am not sure of their business model today.

2m FT8

All day, I have been on 2m FT8 RX. So far (1304z) 39 stations spotted in 8 countries spotted.

UPDATE 1839z: 64 stations spotted today so far in 8 countries on 2m FT8 RX.

UPDATE 2216z: 86 stations copied today on 2m FT8 RX. Soon be time to go QRT.

ABC Classic Sydney, 92.7MHz FM, Australia - NOT amateur radio

A few weeks ago we bought a Brennan BB1 receiver.  This plays thousands of stored music tracks, Youtube videos and 40000 internet radio stations from around the world. Quality is great and the device small. I am mightily impressed.

At the moment, whilst typing this, I am listening in the background to ABC Classic from Sydney, Australia. Quality is first class, as if I was a local in Sydney!

2m FT8

Just now, I tried to go on 10m FT8, but on 2 rigs it was showing hi-SWR, so something is wrong with the antenna or its connecting coax. I shall have to investigate.

In the meantime I am on 2m FT8 calling CQ initially with 10W to the omni antenna. Now I am 2m FT8 RX only. 16 spots of me including GD3YEO (384km) and 6 on 2m FT8 RX with best DX being F6APE (551km).

UPDATE 1252z:  Now 32 stations in 6 countries spotted so far today on 2m FT8 RX.

UPDATE 1815z: 87 stations spotted today on 2m FT8 RX with best DX SM6VFZ (1030km).

UPDATE 1855z: 95 stations in 10 countries spotted today on 2m FT8 RX.

Stations spotted so far
today on 2m FT8 RX
UPDATE 2208: 118 stations in 10 countries spotted today on 2m FT8 RX.

Narcissi - NOT amateur radio

Recently, my wife bought a pot of narcissi for the kitchen table. It will be great to see them come into flower over the weeks ahead whilst having breakfast. They are a real December and Christmas  plant.
