Mr Redington: Firstly, language such as that used in your post is completely inappropriate for this website, which is independent of any broadcaster or transmitter company. Without knowing where you are (please provide a full postcode) we don't know which transmitters serve your location or what your signal strength should be.

StevensOnln1: Why doesn't Briantist filter out comments like Mr Redington's, which clearly breach his rules for posting on this site?

I'd been having intermittent audio drop-outs for some time, particularly on HD channels. Then I got a fancy new Freeview HD tuner device that provides TV channels over my home LAN! Joy! Until I realised that it was *much* more sensitive to the interference that had previously just caused audio dropouts.

On the new box, I get *severe* image interference intermittently. It's *much* worse between around 7pm and 9pm each evening.

After reading up on what could be causing this, I've a strong suspicion that it's a local Business Radio transmitter - see this article http://www.erodocdb.dk/do….pdf for details on how it can interfere with Freeview Ch 21 when you're on the edge of the Freeview transmitter area (as I am).

Anyone know where I can find a register of local Business Radio licensees?

Not fine for me ... I'm getting regular dropouts between 7pm and 9pm. Still strongly suggest local business radio (taxi, walkie/talkie or TETRA) interference.

Just invested in an SDR dongle so I'm aiming to investigate tonight.

I used to visit Saffron Walden regularly in the 80.s and I became familiar with the name of this transmitter due to the loss of tv reception on all channels.Ross Close was where I used stay with friends and the locals used be complaing about Sandy Heath being out of action.
