My VERY old website

Today I discovered that there was a snapshot of my 1997 website on the Wayback Machine. This was almost 22 years ago! In those days we used dial up modems and I seem to recall that my very first CompuServe website (1994 I think - must see if there is a copy of this too!) used a 2.4k modem and involved a long distance phone call to connect. We have come a long way.

If you want a look, the old Demon website is at:

Spring hope - NOT amateur radio

Both our children and grandchildren have collected conkers from these old trees in our churchyard. No doubt children from countless generations have done the same. The trees were planted to celebrate the Battle of Waterloo (1815). Spring has sprung.

Furthermost east on Oscar 100

HS0AJ (Thailand) was just received via the web SDR on SSB via Oscar 100, the geosynchronous satellite. This is the furthermost east I have copied so far via this satellite. Activity on SSB seems to be gradually increasing as more stations assemble gear. He was using 2W, but I do not know the dish size. He must be on the easternmost coverage area.

10m Es already?

10m Es can occur at any time of the year, but it tends to peak May, June, July and August here. About 30 minutes ago I QSYed to 10m FT8 and was surprised to spot EA3HDZ (1213km) as well as a couple of Gs. My own CQ (2.5W) was spotted by no-one.

I am wondering if this is Es and whether with FT8 brief patches of Es (maybe very short-lived) are spotted earlier in the season? The main bulk of long-lived Es openings don't usually start here until late April.

UPDATE 1134z: 5 stations spotted so far today on 10m FT8 RX. 4 are Gs plus the EA3.

UPDATE 1319z: Now 8 stations spotted today on 10m FT8 RX with F6DAY (788km) spotted around 1100z.

I keep forgetting about BST! An hour has to be taken off local time now to get GMT.

UPDATE 1538z: Now 9 stations spotted on 10m FT8 RX today. All but 2 are Gs.

UPDATE 2000z: Still 9 stations spotted on 10m FT8 RX today. I shall be staying on 10m FT8 RX overnight, although it is unlikely I shall spot any now until tomorrow morning.

Sunspots - Sunday March 31st 2019

Solar flux is 69 and the sunspot number zero. A=4 and K=0. Still looks like we are scooting along the bottom of the solar minimum.

472kHz WSPR overnight

Things are definitely going "off the boil" on 472kHz WSPR. Yet again, I copied fewer stations than earlier in the "season". This may be my last outing on 472kHz until the autumn.

Returning summer migrants - NOT amateur radio

It is usually well into April before the common summer migrants here return from Africa. The earliest I have ever seen a swallow here is April 7th, although they are often seen in Devon much earlier. By the end of April they are ubiquitous. I am already scanning the skies!

472kHz WSPR (10mW ERP)

A few minutes ago I QSYed from 10m FT8 RX to 630m WSPR (10mW ERP TX 20%, 80% RX) using the earth-electrode "antenna" in the ground. It usually take about 20 minutes for the transverter crystal to settle on TX. Until this happens I usually get drift. Surprisingly, G8LCO (58km) has already spotted me a couple of times, albeit with drift - this drift should disappear before 1800z.

UPDATE 1750z: The transverter crystal has settled and drift on TX is now zero. M0FMT (51km) now copied on RX.

Sunspot minimum

Although the sun has been spotless of late, there are tentative signs that we may be climbing up from the sunspot minimum. OK, it is hard to tell and many months will have to pass before we can be sure. The last time I looked one forecast had the solar minimum as 2022 or 2023 whereas another said we had already had the sunspot minimum! As said many times, this is a bit like UK weather: sometimes you can be very wrong. 😕
