KB NR40T export radio

[Terry]

Terry, I am not sure that is correct, the rumour of pirates interfering with marine radio was I think propaganda put out by the government ...

Actually, Mike, no!

I knew someone who 'borrowed' the original Trinity House log book one weekend so that I could look at it.

Radio Caroline caused two problems.

One was the 'Luxembourg effect' which was resolved by fitting a counterpoise element to the aerial at the Walton coastguard station and the other was splatter of some kind (I only had the log for about half an hour and it was 54 years ago so I'm heavily dependent on memory here.)

The problem ceased after a few days and a log entry stated that it was believed to have been caused by a faulty insulator on Caroline's aerial.

As for RNI, if there wasn't an adjacent marine band, why did all of those ships have suitable transmitters for operation there? If you heard it at the time, you should recall several simultaneous jamming transmissions, nothing like the subsequent government jamming.

That band may not be in use today but I've heard transmissions in that area in the past on radios which had coverage extending slightly beyond the MW band edge.

Ah! Hold on - I've found something!
