Oscar 100 activity


My last peek at activity on the narrowband transponder using the web SDR at Gonhilly Downs in Cornwall was at 2210z on a Tuesday evening. There was no activity at all, which is the lowest activity I have ever seen. 

My theory is that outside Europe there are few users. In Europe it is late and most people are in bed. Also setting up a satellite station for Oscar 100 is too hard for appliance operators who are mostly old men. 

Overall, I am disappointed. However, I am not too surprised.

6m 6W FT8 (Wednesday)

My IC-705 was turned on at about 0800z. Just 9 English stations spotting me.

UPDATE 1619z:  34 stations have spotted me.  It looks like we may have had some Es? Spotted in 6 countries today.

UPDATE 1935z:  QRT at 1900z approximately.

10m 500mW WSPR (Wednesday)

My QRP beacon is on. No spots.

UPDATE 1930z: 50 spots all by EA8BFK (2880km).

Sunspots - Wednesday April 9th

 Solar flux is 159 and the SSN 167. A=24 and K=4.

SPRAT

Many times I have said that if I ever had to give up all my amateur radio magazines, SPRAT would be the very last to go. It is an A5 colour magazine that comes out every quarter and is packed with articles, many of which are constructional. It is produced by volunteers and people submit articles for nothing. It remains my favourite magazine.

Spirea - NOT amateur radio

This plant produces a splash of white flowers in spring. Sadly, these do not last  long so we have to enjoy them when they are here. 

Our ornamental cherry is just coming into blossom. It will all be gone by the end of the month I expect.

10m QRP FT8 (Tuesday)

 My IC-705 is set at 6W FT8. So far this morning just spotted in Europe and the Middle East.

UPDATE 1538z: 12 stations have spotted me.

Sunspots - Tuesday April 8th

 Solar flux is 162 and the SSN 145. A=13 and K=3.

Old butchers - NOT amateur radio

The UK has a shortage of houses. It would appear most are being built in our village!  

A few years ago our only butcher in the village retired and nobody wanted to take it on, so they re-developed the site for houses. I expect these will go on sale soon.

10m 6W FT8 (Monday)

 My IC-705 was turned on mid-morning. I will reset things as I do not think my own spots are being uploaded to PSKreporter.

UPDATE 1030z: 12 spots of me. I think conditions must still be disturbed as I am only getting spotted in Europe.

UPDATE 1051z:  Everything has been reset, but there are no RX spots here on the screen, suggesting there is little activity. We'll see how things pan out later. Maybe those spotting me are tropo or aircraft scatter?

UPDATE 1108z: Just one English station spotted here on RX. Probably tropo.

Sunspots - Monday April 7th

 Solar flux is 167 and the SSN 145. A=20 and K=2.

Chromebook issue? - NOT amateur radio

For several years I have used a Chromebook as my lounge PC. It has been very fast and uploads software and security patches in the background, so none of this "Windows Update" rubbish.

Very recently I have been having issues with the wi-fi disconnecting after a few minutes. Reading up about this suggests it maybe the router needs the latest software patch. So I turned the router off and on and it seems much better. It still seems to lose wi-fi when it sleeps, but is far better than it was.

Would I recommend Chromebooks? Yes, as long as you appreciate it is not a WindowsOS device so you can't run Windows software. Having said that it does just about everything and is blisteringly fast. I have a Windows10 machine in the shack.   I still have to try Linux.

Overall, I remain very impressed with Chromebooks.

Shetland lambs - NOT amateur radio

As mentioned before, one of my friends on 365project lives up in Shetland. Lambs have started to appear up there.

How simple can you make a transceiver?

 When I was fit (before my stroke!) I liked the challenge of "something for nothing".  This is how this little 80m CW transceiver came about. It is hard to get much simpler.  

My main issue was netting the TX to the RX frequency. I am sure this is a solvable issue. This has been on before, I know.

I think it was in GQRP SPRAT many years ago, but I honestly cannot remember.

 Solar flux is 184 and the SSN 163. A=40 and K=3.

Blue CAT?

 On my phone is an app called RepeaterBook that is supposed to have something called BlueCAT enabled, which I assume is some sort of CAT that works over BlueTooth. 

I have an IC-705 but have no idea how to use BlueCAT. It looks like it should be useful. Any help would be appreciated.

Season switch - NOT amateur radio

 Last year we seemed to go suddenly from winter into summer. After what seemed a long dull winter it is now spring and we’ve had a spell of really sunny ☀️ weather. I must enjoy the moment.

Kent - NOT amateur radio

 


This was our son and grandson earlier this week.
