10m QRP WSPR TX (Sunday)

At about 0840z, I turned on my 500mW W5OLF 10m TX WSPR beacon. So far, just FR1GZ (9724km) spotting me.

Internet time sync - NOT amateur radio

For 10m WSPR, I usually sync time using my atomic clock in the shack. For 8m FT8 and WSPR, I usually sync to internet time using the built-in sync with Windows 10. For some reason (too busy?) this sync was not happening earlier. I shall try again later. As far as I can tell my PC clock error is just a few seconds at most, so I hope this is OK for now.

QDX transceiver

This is a tiny, digital only, HF transceiver that may be used with free software like WSJT-X or JTDX.  It is available in a version for the lower HF bands or 20-10m. Most people buy it as a kit, but I bought mine ready-made as my soldering skills are poor these days. Years ago my fine motor skills were very good. My wife once said that I could write the Lord's Prayer on a postage stamp. She was probably right!

It produces 5W and is very small.

With the popularity of digital modes, this is all most people really need. It works extremely well. Hans makes some excellent pieces of kit.

Mine is regularly copied all across the world on a very basic antenna.

Murder - NOT amateur radio


We saw this dead pigeon (or rather what remains of it!) at Anglesey Abbey, near Cambridge, this morning. It looks like it was killed by a sparrow hawk or buzzard.

Football - NOT amateur radio

Although I rarely go to a football (soccer) match, I take an interest. 

Coventry and Luton were at Wembley battling for a place in the Premier League. It was a hard fought match that Luton eventually won after extra time and a penalty shoot out. 

This was very tense and your heart bleeds for Coventry man who missed his penalty. It was a very close fought match that both teams deserved to win.

Network radios

A network radio has been owned for several years - 5 to be precise! Mine looks just like a 2m or 70cm handheld complete with PTT and antenna. It has been used on Echolink, and on DMR with an app called Droidstar.

The phone is essentially an Android smartphone, so it can run all sorts of apps too.

I'll be honest, I prefer "real" radio where the link is open to the variations of the ionosphere or troposphere. I can see they have their place where conventional RF radio is not possible such as in hotels or care homes, or where external antennas cannot be erected. At the depths of solar mimima, I can see them having a place too.

10m 500mW WSPR TX (Saturday)



For about 2 hours I have been on 10m WSPR with my 500mW beacon. Lots of Es and F2 reports already as the table shows.

UPDATE 1400z: So far today, 45 unique station spots of my QRP with the furthermost FR1GZ (9724km).


UPDATE 1853z:
48 unique stations have spotted my 500mW 10m WSPR beacon today (see table).

8m QRP FT8 (Saturday)

Since about 0950z, I have been on 40.680 MHz FT8 (DF about 1950 Hz, TX first). It is now 1038z and no spots.

UPDATE 1153z:  Spotted by S50F (1205km).

UPDATE 1402z:  Now EI1CAH (690km) also spotting me.

Stations spotting my 2.5W to
a low dipole on 8m FT8 today
UPDATE  1822z:  6 stations have spotted my 2.5W 8m FT8 to a low dipole today. There are some notable stations missing this year. G9PUV and EI9KP have not been seen on 8m TX this year.  G3WCS appeared briefly earlier in the spring, although I have not spotted him recently. So far, today has been a good day with plenty of Es on 8m. 

Es promising (Saturday)

As the indications are that we could have a decent day in Europe with Es, my proposal is still to try 8m FT8 on 40.680 MHz and 10m QRP WSPR with my 500mW beacon. I shall probably turn these on in the next 10 minutes. Later, I might try 8m WSPR on 40.680 (DF about 1550 Hz)

8m Saturday

Today seems to have been the best Es day in Europe this season. 

Even on 4m with an 8m dipole (tuned via an internal auto-ATU) I have been spotted widely in Europe and I have spotted 4m FT8 stations all over Europe.

So, assuming Es will be as good tomorrow, I hope to try 8m QRP FT8 on 40.680 MHz. I may also try some 8m WSPR.

I am convinced that very low powered 8m stations operating on WSPR using ISM rules will be widely copied across Europe. 

In many countries a licence is not needed for beacons on the 40.66-40.70 MHz ISM band as long as national rules are followed. In many countries this means 10mW ERP. On 10m WSPR just uWs have spanned Europe. We know from Australia that 5mW of 8m WSPR has spanned 5000km.

10m QRP WSPR TX (Friday)

As my 10m antenna is free, I am on 10m WSPR TX with my 500mW WSPR TX beacon.  Already, a couple of Es spots.


UPDATE 1024z:  Already 10 unique stations spotted.  Es seems good today.

UPDATE 1517z:
31 stations have spotted my 10m 500mW WSPR beacon today. Most are Es. See the table.

UPDATE 2120z:   62 unique stations have spotted me today. I think this is a record number.
Spots of my 500mW 10m WSPR today


4m FT8 (Friday)

 As I have no 4m antenna, I am using my 8m dipole, tuned via the auto ATU in the FT-710 So far just spotted today by G3SHK (200km) and no Es.

UPDATE 0935z: One G QSO with a station in the UK near Coventry - G4AEH (124km) and again a spot of me by EA6SA (1423km).

UPDATE 1030z: 3 spots of me with 2 QSOs, the furthermost being EA6SA (1423km). Several spots of Spanish stations plus ZB2GI (1848m).


UPDATE  1301z:    Spotted by 10 stations on 4m FT8 (see map). As HC02 (Portugal) was concerned by my timing (even though it should be sync'd to internet time), I have just done a re-sync.

UPDATE 2012z:
65 stations spotted my 4m FT8 today, even with my 8m wire dipole (see map)!

Gobbledegook - NOT amateur radio

I have just received an email from Google AdSense and I am none the wiser!  In my view it is total rubbish. To my mind, it was total gobbledegook.  

Please may I have this in plain English?  

Rallies this weekend

For once, a good weather forecast for a Bank Holiday weekend!

The following rallies have been notified to me, although I always recommend checking the details with organisers before travelling.

Saturday May 27th  - Barry Amateur Radio Society Rally , Sully, CF64 5SP. Contact Steve 07368 140795.

Sunday May 28th    - Durham and District ARS Radio Rally, Bowburn Co. Durham, DH6 5AT. Contact dadars@gmx.com 

8m disappointment this Es season

Both FT8 and WSPR have been given a try on 40.680 MHz.  Apart from Hugh HC02 in Portugal, I have had few spots this season.  My impression is there are fewer people on than last year. 

I know Es has been less good until recently and things could change. For those experimenting on 8m, the more stations on the better, with widespread monitors, even if unable to TX. 

Some quite odd antennas may well be good enough with Es, so if you have a RX capable of monitoring 40.680 MHz, that is probably all you need. 

If 28 MHz looks promising, it may be worth monitoring 40.680 MHz.

This is the real boundary between HF and VHF and a lot may possible.

10m QRP WSPR (Thursday)

 When on 4m FT8, I am on 10m WSPR QRP TX with 500mW. 

UPDATE 1620z: I was wondering why I had got no 10m WSPR spots in the last hour. It helps if you turn the beacon on!! Guess who had forgotten? Doh!


UPDATE 1704z:  4 unique stations have spotted my QRP so far today.


UPDATE 1928z
: 10 stations have spotted my 10m 500mW WSPR today (see table).

4m FT8

 Using my 8m dipole tuned via the auto-ATU in the FT-710, I am on 70.154 MHz FT8. So far, 4 Gs have spotted me with the furthermost G4HGI (244km). No Es yet and nobody spotted on RX.

UPDATE 1905z:  At last some 4m Es, with the furthermost a spot of me by EA6SA (1423km) in the Balearics who gave me a good report. Also a station in Northern Ireland has received me. 6 stations have spotted me on 4m today (see map).
