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.

Jodie: The fact of you having said that others around you are also experiencing problems, plus reports of poor, or no reception from other viewers located around the areas referred to in my previous posting and yet signals from the Sandy transmitter are being received perfectly OK further afield, is a positive indication that reception in the areas of complaint "are" being affected by conditions relating to high pressure, something no one can do anything about except to wait until it clears.
This being one of the pitfalls of terrestrial digital reception, as in analogue days the effects of interference from distant stations generally resulted in a range of visual disturbances, for example, ghostly negative images sweeping across the picture from left to right, wavy lines etc across same, and only in cases of severe interference would the picture become non-viewable, whereas in the case of digital reception interference from distant stations, even if only of a relatively mild / low level nature usually results in picture glitching problems, the quality of the signal frequently being observed to dive down to near zero, any increase in the strength of the interference completely corrupting the digital signal entering the decoder thereby killing reception, this being the type of thing that can give some viewers the impression that the transmitter must be faulty, which in Sandy's case it isn't!

Rushden is one of the areas served by Sandy Heath transmitter that has a history pof poor or intermittent reception when the weather is good or warm/hot - as we have mostly experienced in the last few weeks. So I would suspect that your reception problems may well be due to a known weather-related phenomemn about which no one can do anything (unless you believe in a helpful deity that is).

Daniel: Use of Waltham, or in some places, Sutton Coldfield on a second TV or Freeview box might give a more reliable signal for the PSB channels in some parts of Northamptonshire.
