Sunspots - Thursday May 20th 2021

Solar flux is 76 and the SSN 24.  A=6 and K=3.

60m amateur allocations in the UK

OFCOM has just put the latest amateur licence conditions on its website including an EMF calculator. Running 10W or less, I am not too concerned.

What does concern me are the UK slots at 60m. I am sure I cannot be alone in being totally confused. Yes, we may have more spectrum and higher power (100W) than the small WRC slot, but unless you are a regular user, these slots are messy and confusing. I counted 10 slots!!

Personally, I'd settle for a narrow contiguous allocation than the mess we currently have, and with lower power. I would also like to see more access to much more spectrum with very low ERP limits on a strictly non-interference basis. I guess that is too much to think about. Why can't we follow the Irish example?

See the OFCOM website for more details.

160m FT8

Just after 1800z, I QSYed to 160m FT8. Very briefly I was on QRP with 2.5W TX and the earth-electrode "antenna" in the ground. At the moment I am on RX only. As it is still daylight, I am not expecting any great DX until after dark.

UPDATE 2005z: European DX coming through now now it is dark.

Fresh Green - NOT amateur radio

It is good to see the fresh green leaves on the trees. This was nearby Anglesey Abbey earlier today.

OFCOM and mobile phone repeaters

OFCOM is to allow more type approved mobile phone repeaters to be licence-free to get more reliable coverage indoors. See the OFCOM website for details.

Clematis - NOT amateur radio

 

My wife saw this clematis yesterday walking back from the dentist.

Intelligent life in the universe - NOT amateur radio

This is a subject I have discussed before. Some estimates put the number of planets in the visible universe as capable of having intelligent life as as high as 1400000000000000. Others say intelligent life is incredibly rare.

As far as I know, we have been looking with SETI since the mid 1960s and have, so far, found zero evidence.  Maybe we are looking in the wrong way? As time goes by, we have more sophisticated ways of looking with ever greater sensitivity. Mind you we only discovered electro-magnetic radiation a few hundred years ago. Maybe many societies have discovered something better?

One thing is certain: should we find any signs of intelligent life "out there", it could have profound effects on human life.

10m FT8 RX with the 10FT8R

Just before breakfast I turned on the 10FT8R RX (4 transistors) with the tiny indoor loop antenna. It is now 0818z and 29 stations already spotted via Es.

UPDATE 0835z:  34 stations spotted so far.

UPDATE 0915z: 50 stations so far spotted today.

UPDATE 1131z: 101 stations spotted so far on 10m FT8 RX with the little 10FT8R receiver and the tiny indoor loop.

UPDATE 1426z: 164 stations spotted on 10m FT8 RX so far today.

UPDATE 1740z: 222 stations so far spotted on 10m FT8 RX with the furthermost W1JR (5267km) in New Hampshire, USA, I think this was Es (see map). No South Americans logged today on the tiny indoor loop.

Sunspots - Wednesday May 19th 2021

Solar flux is 76 and the SSN 24 again. A=10 and K=1. 

Thunder

As a precaution, I have disconnected my mains PSU and PC in my shack. My antenna that is connected to my little 10m FT8 RX is indoors (the tiny loop). There is thunder about. I think it is some way off, but better safe than sorry.

We have hail now at 1607z.
