Faye: In the hundred years or so that radio signals have been used by humanity, no one has ever been harmed by them.
If you could, perhaps, provide a postcode of the location it would be easier to be more specific.

John Taylor: 868MHz *WAS* allocated to "PMSE" (programme making and special events). This frequency was cleared and has now been sold to O2 for 4G operations.
Assuming you don't mean on a closed (CCTV) system, use of this frequency for another purpose would constitute an illegal broadcast, and must cease forthwith.

Sara brown: See UKTV's Drama to be on Freeview 20 | Freeview news | ukfree.tv - 10 years of independent, free digital TV advice please.
UKTV needed to put something in their slot until they could get Drama ready.

It's worth noting that for digital transmission, the way of measuring the quality of the signal is the "bit error rate".
A BER of 1:10,000 (for example) means that one unrecoverable error happened in every 10,000.
The actual signal strength doesn't matter, and is a bit of a misnomer.
If you are seeing a "percentage" bar for signal quality on equipment X, it won't relate to that on equipment Y.
The COFDM system (which DAB uses) pushes multiple copies of the signal over different frequencies (digital subcarriers) - everything on DAB is transmitted twice, in effect.
So, it's only when the receiver is unable to recover a bit from the multiple transmissions is a "bit error" detected.

mendenhall: If you don't get the channels when you take out the card, try Method 1 on the What can I do when my Sky Digibox says 'No Signal' or 'Technical fault'? | ukfree.tv - 10 years of independent, free digital TV advice page, and if that doesn't work Method 3.

Pete Marshall: It's worth noting, as per the table above, that the BBC stations are all carried together in a single transmission, the "BBC National DAB".
If one of these station is affected, they all will be.

n holborow: why not call the national number... It's their job to deal with faults.
