472kHz ATU

There is a common misconception that 472kHz ATUs have to be big. With low power this is not the case. With my 5W I have had no problems at all with a tapped ferrite rod as the photo shows.  With the outer of a coax this makes a very simple 472kHz station. The 50 ohm connection is very low down and the wire will be much further up the rod.

Typical Cambridge - NOT amateur radio

When thinking of Cambridge people often think of bikes. 

This collage was taken by my wife earlier whilst coming back from her U3AC course.

SPAM - NOT amateur radio

Gmail does a pretty good job fighting SPAM. 

About 1 in 1000 is classed as SPAM but isn't, so I usually check. Every day I must get 10-20 SPAM emails, usually telling me I have a vast sum in my bank account (or about to if I just share my details), Bitcoin credits or offers of great sex with no strings. 

Several times a day these all get deleted. You can usually tell which are SPAM.

Overall, I can recommend Gmail. It is free and you can log in from anywhere with 15GB storage free.

Quiet on the River Cam - NOT amateur radio

The photo shows the River Cam in Cambridge UK last Friday. There are fewer foreign visitors this year, although Cambridge was about twice as busy as the last time we went in the summer. A hopeful sign.
