Ah well - it was just a guess. I get it on 95.8 here (near Edinburgh).

When ever I have that channel on, there is a hum from the speakers


Is there an electrical fault, that could cause it?



I presume that you are using the Wrotham radio 4 transmitter?. It is
possible for a transmitter to have a fault on it for some while
especially if its a relay station out in the sticks, but a transmitter
in earshot of Broadcasting hice isn't likely to be duff for long!.

Are you certain that radio 3 hasn't got the same hum?.

I cant say I've heard of a tuner doing a similar fault like this on
different frequencies.

Mains hum loops are possible, and I've had one here as the aerial in
question is very well earthed for lightning protection, and that set up
a good 'um loop.

Question.. is there any fluorescent lighting close by?.

Other than that difficult to point out the cause, is it possible you can
post up an MP3 sample of the hum and quite bits of R3 and R4?....

And you are using Wrotham, and how far away might you be?...

So perhaps, at around 6-8 miles, your poor old tuner "may" be having
some sort of overload crisis.

Suggest trying a simple "coathanger" or bit of stretched out twisted
flex as a temporary aerial, and see if that cures the problem.

It might be some sort of very odd intermodulation product that's causing
this. At that range even a paper-clip stuffed in the aerial socket
should get a noise free signal!.

Is it the same on mono and stereo?....

House lights are not the only source for such problems. Some years ago a
friend of mine had one of the old Quad FM tuners that used a pair of neon
lamps as tuning indicators. He started getting a 'hum' on R3 which I found
was due to one of the neons singing. Replaced the neons, problem vanished.

Slainte,
