The Shard: London - NOT amateur radio

This is (I think) the tallest building in London. It certainly can be seen for miles!  

The photo shows a view from outside Southwark Cathedral last Thursday. 

Oscar 100 narrrowband activity


Every few weeks I take a peak at the activity of the narrowband transponder of this satellite. The last time was on a Friday early evening in Europe. 

Activity continues to disappoint me. Whilst for some this has been an introduction to microwaves, I was expecting far more DXers to make use of this. 

As I have said before, I think it is just too hard for many. The main markets of the USA and Japan do not come within the satellite footprint. This means there are no mass market "black boxes".

Over the solar peak?

In my opinion we have just passed the solar peak. We can expect a few years of good conditions, but I expect the trajectory to be slowly downwards.

Web archive - NOT amateur radio

Some of my time after lunch was spent browsing the Internet Archive. This is an absolute treasure trove of old material. Some time back I found a snapshot of my very first website dated 1996. If you want to look at old material about anything it is worth looking here. I am pretty sure much old stuff is on this archive.

There is a radio archive at https://archive.org/details/dlarc .

Another site worth a browse is https://www.worldradiohistory.com/ .

It would appear most things from the past may be found if you look hard. I have only scratched the surface.

Mudlarking - NOT amateur radio

Mudlarking is the term for looking for rubbish on the shores of the River Thames in London, UK. The earliest ever banana in London was found as a result of mudlarking.

6m QRP FT8 (Friday)

 If my QMX+ initiates (it hasn't yet!) I intend to try 6m QRP FT8.

UPDATE 0945z: Well, the QMX+ eventually did initiate. Probably this occurred in the first 20 minutes. The secret seems to be just to leave it. I would have expected this to happen within seconds. This is not fatal, but definitely needs fixing or explaining. Otherwise the QMX+ works really well. So far, spotted by 7 English stations on 6m QRP FT8 this morning.

UPDATE 1238z: 19 English stations spotted.

UPDATE 1545z:  30 stations have spotted me. Some are European. F2 backscatter?

10m QRP WSPR (Friday)

 My 500mW WSPR beacon was turned on at about 0915z. No spots.

UPDATE 0947z:  Spotted by 4 stations so far.  These look like by F2 propagation.

UPDATE 1243z: Spotted by 9 stations.

UPDATE 1603z:
   30 stations have spotted me with the furthermost PU5ALE (10191km).

Sunspots - Friday November 22nd

 Solar flux is 166 and the SSN 148. A=8 and K=2.

Tower Bridge - NOT amateur radio

As we were in London to see "Guys and Dolls" at the Tower Theatre with our village theatre group, I decided to take this photo of Tower Bridge as we left. Being in London, there was no radio today.
