Jules: Could just be that Sandy Heath has upped its power level a little, and its flipping out that particular mux. Whats the signal strength on BBC1?

I'm at mk16 8 and am getting big interference on c27 (bbc 1 etc). Is there another transmitter somewhere that's just been turned up? I've been away for 3 weeks and it was fine before I left (I think). I am an antenna engineer and have a promax signal tester, the strength is fine on this mux and all other muxes seem ok, just c27 has crazy high vbers. Have tried a different aerial and result is the same. Anyone know what's going on?

Jodie: If you put your postcode into the site, you can click on the Digital UK link Coverage Checker - Detailed View Your 45km from Sandy Heath, and apparently with a decent signal. Check that your actually tuned to Sandy Heath - your TV might have picked up Crystal Palace during a retune and obviously thats a less powerful signal. If not, then it looks like your system - perhaps a corroded connection, frayed cable, etc. Always check your aerial lead - it might be loose or broken.

Jodie: Northamptonshire, including areas to the South of stretching right across to the East of England are notorious for suffering from reception problems at around this time of the year, basically because most (but not all) of them do "not" (including yourself) have a line-of-sight to the Sandy transmitter, the result of this being that the signal from Sandy is prone to reacting to interference from distant stations, including in some instances ones from outside of the UK.
In most cases nothing can really be done about the problem, that is except to wait until conditions turn more favourable.
