While testing an IQ upconverter chip, I discovered I've got several
tens of millivolts of Virgin AM on 1215kHz coming out of my PC's audio
output. There is enough signal to see it on a frequency counter and
view the AM on a scope.
There is presumably a transmitter nearby, and/or some curious
resonance in the house wiring that accentuates pick up of this signal.
Its not the LF antenna picking up the signal, so I'm wondering if the
ring-main is forming a resonant loop :-)
Does anyone know where the transmitter site for this station is located?

Hello Andy,
I think you're near Southampton?
Best guess (you're a bit out of my area) is Fareham, 1KW (low power
filler - HI!)
Found this listing too

Any help?
