Thx for the link.
Merlin closed down abruptly during a song 'lolly, lollipop' sung by a female.
That would have been around 0724 UTC.
I hope it wasn't because of a bust by OFCOM!
They probably close down during the daytime, as propagation is less good. I have read that Radio Merlin has got caught a few times in the past by OFCOM and it's predecessor the DTI, because they were using the wrong frequencies it was said, and I think this is why they now only broadcast on 6305 khz. To be honest, I think OFCOM know where they are, maybe they are just not acting against them at this time, higher priorities and less government funding? It would be different if they transmitted on the FM band, I'm sure... let's just say occupying the FM band involves taking a piece of higher value real-estate in the RF spectrum, as far as the government is concerned.... it's all about money, usually.... although they claim it is due to interference... well maybe it does interfere with their income and finances
There are still a number of UK based pirate stations on shortwave, just not broadcasting as frequently as Merlin.
