Birds - NOT amateur radio


This photo of a stonechat (if it was on before, blame me!) was taken a couple of weeks ago on the Dee estuary near Liverpool. I spotted a swift yesterday, but I suspect the adults have started their migration southwards.

UPDATE 1630z:  5 swifts seen this morning. Young?

10m QRP FT8 (Wednesday)

 My 2.5W QRP FT8 was turned on before breakfast. I was called by a station in Portugal when there was already widespread Es.

At 0830z 82 stations have spotted me (all in Europe) and I have spotted 50 unique stations.

UPDATE 1303z: 131 unique spots of me so far today. 

UPDATE 1702z: 261 unique stations have spotted my 2.5W 10m FT8 today.

UPDATE  2004z: 
363 unique stations have spotted my 2.5W 10m FT8 (see photo). Furthermost 2-way QSO was with Brazil. Now QRT.

Sunspots - Wednesday August 2nd 2023

Solar cycle peak this year?

My favourite site for solar data has just been updated. It still show the peak of solar cycle 25 as November 2023 with a peak of 144.2 (this is up slightly). This seems early, but it has been late this year now for a very long time. If so, conditions could still be good for several years to come. It is definitely worth watching 10m FT8.  I suspect 10m will remain open far more than we thought.

10m QRP FT8 (Tuesday)

 For a change, I am on 10m (not 6m) FT8 with my 2.5W.  The 10m antenna is a low Par end-fed. At 0816z 3 stations spotted on RX with the furthermost FR4OM (9763km) on Reunion in the Indian Ocean. Just 3 spots of me, all in Europe.

UPDATE 0842z: 7 stations spotted on 10m FT8 RX today (see photo).

UPDATE 1106z:  13 stations spotted on 10m FT8  RX so far today.

UPDATE 1735z:  132 spots of my 2.5W QRP FT8 with 2 in South America.

6m FT8 yesterday

 As well as the usual crop of 6m FT8 European stations received via Es yesterday I spotted D2UY (6525km) . Call me suspicious, but I suspect this was a pirate in Europe. Does anyone know if this is genuine?

Yes, you may call me "lord"!! - NOT amateur radio

 I had a very ordinary life!

FT-710 on 8m

Someone posted on Facebook today that the FT-710 is about 10dB deaf on 8m. It can be persuaded to TX on 8m by putting it is engineering mode by pressing buttons. However use outside of offered amateur bands probably invalidates your warranty. I have no idea what power it puts out on 8m as I never tried it. I sold the FT-710 some time ago.

Optical communications - over the horizon


When fitter, I really enjoyed experimenting with this. Actually, I don't think this needs a licence at all, but it is real experimentation. Anyone can do this without costing much. 

All my gear and much of my test gear was homemade and very inexpensive. It is real "back of the garage" stuff. All my gear was homemade in the back of the garage. The only special test gear was a very weakly lit LED. If you have a multi-meter and scope, you really don't need much else. In my view optical communications is easier than microwaves as the test equipment is easy.

I was quite surprised how easy it was to copy an optical signal "over the horizon".
