I first noticed this at just before 12:00 today (Oct 24). BBC R4 has
been replaced by a carrier heavily modulated with white noise. It
extends from 93.1 Mc/s to 93.7 Mc/s. There is a fainter carrier at 93.9
Mc/s carrying the normal programme.

There is also a strong unmodulated carrier at 100.16 Mc/s.

This is in the Bath area which is served by a local transmitter at
Bathampton Down and the Mendip transmitter.

And how would you say this compares with the usual programming :-)

Well, almost. Mendip transmits TV, DAB and some commercial local FM
radio but NOT BBC national stations. For national in your area you have
to go to Wenvoe for high power, or as you say Bathampton a for lower
power relay.
At least where you live Bathampton is line of sight so it isn't a signal
strength issue!

No problem with signal strength, it was quite a bit stronger than the
signal Bathampton Down usually provides and looked like a solid block of
mush 600 kc/s wide on the panoramic adaptor. It was just possible to
hear R4 modulation underneath it, but I don't know whether that was
being transmitted with the mush or whether that was the Bathampton
signal just audible through it.

R4 is back to normal now but the unmodulated carrier is still there at
100.16 Mc/s.

About the same as regards entertainment value, length of pauses between
items and intelligibility of interviews. Slightly worse compression
(100% mod continuously), definitely better for lack of trails.

I listened continuously for longer than I usually do, but that might
have been because of the novelty factor.

National FM from Wenvoe yesterday was shut down between about 10am and
2pm to allow guy rope maintenance

The same occurred on Sunday in the same time period.

Wenvoe's relays (Ilchester Cres, Bath etc) will have been transmitting shash

Ridge Hill on Sunday was retransmitting a Spanish station that is on
Wenvoe's R2's frequency

93.9 is Radio 4 Oxford

I would have thought that if the main (source) station went off (1) the
relays would have had a squelch on the receiver, and (2) either it
should shut down the transmitter as well or make it playout from a
memory stick with an engineering message. At least that is what used to
happen on commercial stations with which I was familiar.

Thanks, that would explain it.

Presumably Bath simply translates a band of frequencies for
re-radiation, rather than three separate carriers, which is why the hash
was continuous with no noticeable gaps.

My Eddystone 770R was doing well to pick that up so cleanly on a grossly
mis-tuned vertical dipole.

That is what they would have done overnight, before 24/7 broadcasting.

No, there is a discrete transposer for each service. In Bath's case six,
R1, 2, 3, 4, (fed from Wenvoe) BBC Bristol and Heart (both fed from Dundry)

I suspect there was (is) a fault with one of those transposers

I have always wondered: is the quality from a relay transmitter not
quite as good as a main transmitter?

It can't be better, or exactly the same, but it can be pretty close (for
FM relays).
I've compared the output of my local relay with its parent, Oxford, and
can't really detect a difference. By the way, Oxford itself is off air
fed from Sutton Coldfield !

Different kettle of fish of course with DTT etc. Just a case of
_exactly_ the same 1s and 0s !

Is it also true that Wrotham is better than any other transmitter, or
was this entirely historic?

All the main transmitters are fed 'digitally', so the output quality of
Wrotham should be identical to, Black Hill and Meldrum

It used to have a dedicated microwave link input feed, where eveywhere else
had 8kc/s GPO lines, but once the 13 channel PCM feed came into service,
all were theb same - including Wrotham.

I don't what is used now but previous ones were notorious for not muting

Perhaps the noise should be on R3? They have always liked their experimental

Probably a lack of lock on a digital input. Too much of the wrong kind of

Memories of the Shagbut, Minnikin and Flemish Clacket.

If you think R3 was odd, you should have heard some of the programmes on
Resonance F.M. My programme, where I D.J.ed 78s. barrel pianos and wax
cylinders, in the manner of a 1950s BBC announcer, was positively
mainstream by comparison.

Search for "Life Before Vinyl". I believe you can still download the
programmes from Resonance F.M. but if you can't, follow this link...

http://www.poppyrecords.co.uk/lifebeforevinyl/P01.htm

Directly underneath where it says :Programme 1" is a dot, click on that
for an MP3 download. Similarly on all the other programme pages.

P.S. I was using my previous name in those days.

radio@arqiva.com

They usually take sensible complaints seriously..

Be a waste of time contacting the BBC :-(

In the past some crummy feed of radio 4 was broadcast if the input failed,
not just noise.
