Waiting for the bus - NOT amateur radio

In the UK bus travel is free most of the time if you are old. It is as quick to go into Cambridge by bus as by car and is totally free. This was earlier waiting for our bus.

10m QRP WSPR TX (Wednesday)

VLF transmitter

 

Looking through some old photos I came across this one of my VLF transmitter that was used for earth-mode tests though the ground. 

It produced about 5W and my best DX (before my stroke intervened!) was about 6km. Much further would have been possible.

Since my stroke, I have been unable to continue my VLF tests. It is still on my shelf.
