Huge satellite - NOT amateur radio

A huge satellite should be clearly visible from Earth. In fact some astronomers are worried that this and its companions could be so bright they may interfere with some observations on earth.

12m FT8 RX

As 8m was drawing a blank, I went on 12m FT8 RX using the 8m (i.e. well off tune!) antenna. To my surprise, it was full of FT8 signals around 24.915 MHz. After probably less than 15 minutes, 126 unique stations spotted. I did try 15m briefly, but this was much the same.

UPDATE 1446z:  301 stations spotted from most parts of the world.

10m WSPR QRP TX (Saturday)

As the 10m antenna is available, I have remembered to go on 10m WSPR (I keep forgetting I can do this!).  No spots yet today.

UPDATE 0918z:  Several spots from the Canary Is. These look like single hop F2.

UPDATE 1650z:   21 spots so far, with lots from the USA. It appears I am romping into the USA on 10m WSPR.

8m QRP FT8 TX (Saturday)

The 8m FT8 gear was turned on at 0846z on 40.680 MHz.  No spots yet. 

UPDATE 0938z:    No spots.

UPDATE 1645z:    I am trying again on 40.680 MHz FT8 QRP to get spotted in the USA. Alas, no spots.

Speech processing

Most rigs of the modern era have speech compressors. Early radios did not, and it was vital to make sure your signal was "punchy". I well remember an article in an early VHF Communications magazine that looked at this.

Norwich market - NOT amateur radio

Norwich is a fine city with a great market. We visited there on Thursday. 

10m WSPR yesterday

As I was on 8m FT8 yesterday evening and the 10m antenna was free, I decided to go on 10m WSPR TX with my 500mW beacon. 

As well as several Ws, I was spotted in Antarctica by DP0GVN/3. which is the German base down there. This is the first time I have been spotted in Antarctica this solar cycle.

Sunspots - Saturday October 8th 2022

 Solar flux is 160 and the SSN 146. A=15 and K=3. 

8m QRP FT8 TX (first)

As 10m was looking promising, I have switched to 8m FT8 TX on 40.680 MHz.

UPDATE 1640z:  No spots on 8m FT8.

UPDATE  1921z:   No spots. Now QRT on 8m.

Autumn splendour

For about 6 years we have been following this tree at Anglesey Abbey nearby.  

At the moment it looks magnificent, but in a few short weeks it will be bare until spring. I just love seasons.
