Sunspots - Wednesday May 15th 2019

Solar flux is 74 today and the SSN 24. A=36 and K=1.

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

Lisbon, built on 7 hills like Rome, is famous for its old trams.

It suffered a major earthquake in 1755.

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.

HF beams

A few days ago I reported seeing no HF beams in Portugal. Yesterday, I saw 2. Perhaps they are more affluent further south?

FT4

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.

Sunspots - Tuesday May 14th 2019

Solar flux is 76 today and the SSN 24. A=4 and K=2.

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.

Oscar 100 - still very quiet

When I took a quick look at the Goonhilly SDR relaying the narrowband transponder just now there was only one QSO going on.

Viseu, Portugal - NOT amateur radio

Viseu Street

Yesterday we were in Viseu, whereas today we are much further south near Lisbon. We saw plenty of storks near Coimbra, but none since. I keep looking for bee-eaters. but have seen none.

Web SDRs

Southgate News has a piece about the Farnham Web SDR. These days there are web SDRs all over the world, so you can take a peek at what things are like from other places. It seems odd to listen to a UK 10GHz beacon in Lisbon!

Sunspots - Monday May 13th 2019

Solar flux is 77 and the sunspot number 24. A=4 and K=1. Still looks (to me) like we have passed the solar minimum.

Oranges - NOT amateur radio

Today was hot in Portugal! Earlier in the week we had had rain and clouds, but today could hardly be more different. Even at midnight it is expected to be 24 deg C. On the way towards Lisbon we stopped at Obidos where these oranges were on display.

Lightning maps

Periodically I take a look at the lightning maps to see how near storms are. At the moment they are well away.

Sunspots - Sunday May 12th 2019

Solar flux is 76 today and the SSN 25. A=8 and K=3.

The Moon this afternoon - NOT amateur radio

This was the Moon at about 1430z this afternoon near Viseu, Portugal. And to think men walked on here in 1969.

Who do you believe?

When it comes to solar forecasts it is hard to know who to believe. For some years I have been following this forecast and at the moment it seems to be accurate.

Sunspots - Saturday May 11th 2019

Solar flux is 76 today and the SSN 25. A=8 and K=3. Certainly these figures suggest we are starting the climb.

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.

Plenty of swifts, swallows, house martins and sand martins about.

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.

Sunspots - Friday May 10th 2019

Solar flux is 75 today and the SSN 25. A=7 and K=2.

Porto - NOT amateur radio

It rained today in Porto, northern Portugal. In fact as I write it is probably typically English weather - a mix of mist and rain!

One of the joys today was a visit to the cellars of Cockburn's who make port and have done for centuries.

Anywhere looks drab in bad weather. Certainly Porto is not a place I would rush to return to.

Dayton Hamvention

This ham gathering is perhaps one of the biggest in the world and a place, traditionally, where the big manufacturers launch new products, often long before they are actually available. You can just imagine the engineers rushing to meet Dayton deadlines: you must meet these dates!

I am expecting several SDR based offerings. It would be nice to see a real FT817 replacement. The FT818 was a great disappointment. It was clearly aimed at keeping Yaesu factories going and not offering the features many expected.

Dayton dates are May 17-19th 2019.

Crystal replacements

It is a very long time since I was fit enough to do serious project building work, but I know that buying crystals, unless you are buying very common frequencies, is expensive. Many now use synthesised sources instead as this can be much less expensive. Sadly, health issues have precluded me doing my own experiments. At one time, synthesised sources could be noisy, although I expect things have improved in the last 10 years. If you have used synthesised "crystal replacements" I'd be interested to hear what good solutions there are now.

Many years ago, I had ideas for a low cost 10m DSB rig. With the sunspot count likely to soon be on the up, perhaps it is time to dust this off.

Sunspots - Thursday May 9th 2019

Solar flux is 78 and the SSN 27. A=5 and K=0.

DX VHF FM QSO

The IARU VHF/UHF Region 1 Newsletter has details of the FM 2m QSO between ZS3 and ZD7,

Southgate News

Southgate News is a good source of information about amateur radio, Today includes news of a big solar flare amongst other snippets.

Swifts - NOT amateur radio

Today, I saw my first swifts (birds) this year. They migrate up from Africa, returning in August. The only problem was these were in northern Portugal! What is amazing is these could be the very same ones we see in our village stopping for a "pits stop" to re-feed before flying on northwards. When I see swifts I think summer.

Sunspots - Wednesday May 8th 2019

Solar flux is 78 today and the sunspot number 27 (quite decent for this part of the cycle). A=5 and K=0. It looks to me as of we have passed through the minimum, although this could be just a blip. At the last minimum we went months without spots.

2m activity contest this evening

As this is the first Tuesday in the month, it is the RSGB's UKAC activity contest starting at 1900z for 2.5 hours. Activity levels are usually high on SSB. This is a fun contest.

Sunspots - Tuesday May 6th 2019

The solar flux is 75 today and the SSN 14. A=4 and K=1.

OFCOM - Communications Monthly Update - April 2019

OFCOM has produced its monthly update of this. See their website.

First cuckoo heard - NOT amateur radio

At about 10am today UK time, I heard my first cuckoo this year up here. They have been around for a few weeks, but this was my first heard. This one was not too close. They quite like reed warbler nests.

6m FT8

Plenty of Es about early today. Already 20 stations spotted by 0830z with best DX spotted SP5AOZ (1398km).

Sunspots - Monday May 6th 2019

Solar flux is 75 today and the SSN 14. A=4 and K=1.

G3WMS SK

Yesterday I mentioned my happy days at Liverpool University and how one mad keen radio society member had done great things and gained an MBE. That amateur was Ian Vance, G3WMS (wild man of Somerset). Sadly today I found his obituary:  he died over a year ago. At one time he was the boss of STL. RIP Ian.

10m WSPR TX (500mW)

At about 1130z, I QSYed to 10m WSPR TX. It usually takes about 20 minutes to settle. I am running 500mW, 100% TX, randomised frequencies.

UPDATE 1630z: No 10m WSPR spots so far today.

UPDATE 2025z: Just a single 10m WSPR spot all day!  This was by DK6UG (633km) at 1802z.

6m FT8 RX

At about 1130z I QSYed to 6m FT8 RX. So far, just G spots.

UPDATE 1552z: Some Es about with a couple of Italians spotted at lunchtime. 21 stations spotted so far today with the best DX on 6m FT8 RX IZ2CPO (1004km).

UPDATE 2027z: Quite some Es today on 6m FT8 RX with a total of 32 EU stations spotted.

Stations spotted here today on 6m FT8 RX

Choir

Last evening, my wife's choir was singing in the chapel of Trinity College, Cambridge, UK.
