 My QMX+ has been on since about 1035z. So far, 5 English  stations have spotted me. The QMX+ initialised after a few minutes!

UPDATE 1145z:  10 stations have spotted me (all English).

10m QRP WSPR (Sunday)


My 500mW WSPR has been on since about 1015z. So far spotted by 10 stations.

Climate change - NOT amateur radio

It is a very odd person (probably living on Planet Zog) that cannot see that our climate is changing. We may argue if this is cyclical or as a result of man, but changing it is.

In some countries it is of minor significance, whereas for some it is becoming an existential crisis. In some places there have been devastating floods, or droughts or very powerful hurricanes. If sea levels rise whole nations could disappear beneath the waves.

A fact of life is that poor countries suffer the most. Many of these we depend on for food.  In the long run we will all suffer if we are selfish as nations.

Digital modes compared

This is a link I came across when looking at videos about LongChat (see previous post). I think it was done before FT8 appeared. I think FT8 works down to about -21dB S/N although I have had some decodes at -24dB S/N.

LongChat

This is a mode of message transmission I had not heard about before. It is claimed messages can be sent using extremely low power using chirped signals. I am no expert at all on digital communications!



Sneezing and speed - NOT amateur radio

Two things I have put down to my 2013 stroke may seem bizarre to others. They are my perception of speed (as mentioned before) and sneezing.

For some time I have been aware that my perception of speed is "different" in that I feel I am going 20mph faster than I am. I was not aware of this in a coach until this week. On the way to London in a coach we seemed to be going very fast. In a car this is noticeable when I think I am going over 60mph and look at the speedometer and see I am doing less than 50mph and there is a queue of cars behind me!

The second thing seems trivial, but when I feel a sneeze coming on I always sneeze. I am sure this is different.

These are only mentioned as they are subtle artefacts I think of my stroke. Probably others affected by strokes have noticed other things affecting them.

London sights - NOT amateur radio

London, the capital of England, is a fine city with a mix of old and new buildings. 

Some of the old buildings are known the world over. 

We went there on Thursday with our village theatre group by coach.

6m QRP FT8 (Saturday)

Once my QMX+ initiates, I intend to try 6m QRP FT8 again. Yet again, it has not yet initiated. I hope there is a fix for this in later software or hardware as I am suffering this bug most times I switch the transceiver on. It otherwise is a very good rig that I enjoy using. On early production, I suppose this is to be expected.

UPDATE 1006z: The QMX+ has initiated, but I do not know how long it took. So far just 4 English stations have spotted me.


UPDATE 1347z:
  Spotted by 21 stations including 1 in Germany.

UPDATE 1645z: Spotted by 25 stations (in Europe) and on RX VO1AW (3801km) spotted.

10m 500mW WSPR (Saturday)

 Since about 0945z I have been on 10m QRP WSPR TX with my beacon. No spots yet.

UPDATE 1009z:  Just 2 Finnish stations spotting me.


UPDATE 2039z: 
 23 stations have spotted me. QRT shortly.

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".

Sunspots - Saturday November 23rd

 Solar flux is 179 and the SSN 170. A=12 and K=1.

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.
