Re: Four more MW radio transmitter closures.
You've probably got a good point there Nick....

I remember when the BBC site opened, must have been about 1972. Radio Manchester, a mere 18 kHz from Luxemburg, made listening to the latter a bit of a challenge here in Prestwich, even using my R107. Conspiracy or what

Re: Four more MW radio transmitter closures.
I went on a visit to Pebble Mill around the time BBC Radio Birmingham arrived on MW and I remember during the introductory address from the stage to the assembled mass a gleeful comment that Radio Birmingham was now on 206m and also providing “an effective block to Radio Luxembourg”.
Fortunately, in my location, my even then vintage battery vanity case valve set donated by an aunt and hooked up to a mains power supply, was selective enough for it not to be a problem. Monte Carlo on 205m was a bit more of a challenge. |

Re: Four more MW radio transmitter closures.
It was R. Monte Carlo that carried Radio Geronimo, wasn't it? That was midnight listening for me and my older brother as we lay in bed.

More MW closures
Not really unexpected, but another batch of local BBC radio to close their MW transmitters in the next few weeks...

Re: More MW closures
Radio Devon is bad news - can receive in Lynton (just in Devon) but not on FM.

Re: Medium Wave Transmitter Closures.
I wonder what MW DX will now emerge from beneath the blanketing-effect of these local signals?
Some may moan about the shutdown of local MW transmitters, but to those of us who are more interested in hearing a station rather than listening to it, it presents an opportunity! [shame about the SMPS hash that sets the noise-floor these days] |

Re: Medium Wave Transmitter Closures.
With a good loop antenna, receiver, and perhaps a pre-amp. it is possible to receive
U.S. and Canada, I have also heard the Caribbean and Brazil. We used to rely on the 10kHz spacing as some channels were inbetween our 9kHz channels. I remember a really severe SID (Sudden Ionospheric Disturbance) some years back. There was no hf propagation at all, but I heard a strong distorted signal at 6MHz. This was the intercarrier TV sound signal (FM) leaking from a nearby (analogue) TV! |

Re: Medium Wave Transmitter Closures.
I recall some sets used to radiate this very well. Wasn't there a commercially available 'TV Hi-Fi' system that used a small sniffer coil rather like a telephone pickup coil to sample the 6 MHz signal from the TV and pass it to a demodulator then out to your hifi? I think it may have been of Tomorrow's World'.

Re: Medium Wave Transmitter Closures.
Yes it was the Celestion "Tele-Fi" - I found an example at a rally for 50p, all that was
wrong was a dry joint. TV sound spec is of course FM +/- 50kHz, 75uS pre-emphasis. |

Re: Medium Wave Transmitter Closures.
Hello.
Its sad regarding the closures on MW, in the workshop to day i have a Pye 39JH playing i have a good loop antenna so the sound is first class but with out the loop antenna i may as well not turn the radio on. kevin |

The other night I took a walk up the road with a basic Sharp walkman, I picked up a US religious station, plus a few other interesting bits on Medium wave, and quite clearly too. I think the time of day and weather situation might have been a factor. I suppose the noise is low power and doesn't radiate very far, but in our homes we're in the "near field" of it. |

Re: Medium Wave Transmitter Closures.
I hope they don't give away these frequencies at the ITU meeting, like they did with the old BBC Sussex freq.
They should be put up for grabs to British users before giving away what isn't really theirs to dispose of, especially without any open discussion. |

Re: Medium Wave Transmitter Closures.
If Ofcom don't have any takers for licences for that band, then they don't have a case they can use in arguing to retain the channels. So they will go to any country's agency that has someone interested. They can't deny channels to someone who would use them, just to keep them empty for someone who won't use them.
Maybe our government could put in a bid to use them for some sort of public service? If so it's in the hands of Ofcom, and they'll want to see a source of income to pay for their management. Our government seems to be a bit busy at the moment. The best we can hope for is that it doesn't wind up in the hands of some service that could get stroppy about what's in your pantry. David

Re: Medium Wave Transmitter Closures.
Some years ago RA / Ofcom was proposing the use of frequencies around 2-3MHz for local narrow band FM broadcasting. I did not hear of the outcome - any one know ?
