1923 crystal set

This was crystal set was made by BTH . 

Imagine the thrill in those early days of radio. 

When I retired some years ago I was bought a Gecophone 1920s crystal set that worked.

I had a webpage for the Gecophone on my old website that I must put on my more recent site.

My old website is still there, but the links may not work as this site is not being maintained.

Sunspots - Monday May 26th

 Solar flux is 133 and the SSN 90. A=6 and K=1.

R1155 receiver

With its companion TX the T1154, these were the main radios in Lancasters in WW2. I expect they were a familiar sight to my dad!

In the years following the war they were popular with radio amateurs on the surplus market.

This is a photo supplied by John G3ZTY of it installed in a Handley Page Hampden (on its side as space was so tight!).

Internet time

Many digital modes need the PC to have accurate time. For several months now I have just used the Windows 10/11 system of linking to internet time. As far a I can tell, this works perfectly.

How do you do this?  On Window 10 there is a time/date shown on the bottom right of the screen. I cannot speak for Windows 11, but I assume this is similar. RIGHT click and the select "adjust time and date". Select "sync now" in the box that appears. I do this every morning, but I doubt you have to do it this often. Once the tick appears your PC is synced to internet time. Easy.

10m QRP WSPR (Sunday)

When on 6m, it means my 10m antenna is free, so I go on 10m WSPR with my 500mW W5OLF WSPR beacon (if I remember!). This does not need the PC. Once the time is set (I use an atomic clock) it is entirely stand-alone.

UPDATE 0921z:  No spots.

6m 5W FT8 (Sunday)


My gear was turned at about 0900z .

UPDATE 1010z: 16 English stations have spotted me this morning. No Es seen yet.

UPDATE 1815z: 61 stations have spotted me today. Lots of Es.

Sunspots - Sunday May 25th

 Solar flux is 130 and the SSN 105. A=5 and K=1.

What is this?


This was on the QRPer.com website, but I don't know what it is. It may have been a concept model that never got to market? I like the looks. If anyone has more data, please leave a comment.

Hamvention 2025

This is now well and truly over. 

Dayton, Ohio, USA (where it is held) is probably the biggest ham gathering on the planet and often the place where new rigs are announced. I am not aware of anything from the major Japanese companies.

Often visitors come from other countries. It would not surprise me if foreign visitor numbers are down this year.

6m 5W FT8 yesterday

 In all, 58 stations across Europe managed to spot my QRP 6m FT8. As yet, I have not yet seen any super DX on 6m.
