The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Up until today (yes I have retuned today from factory resets!) I got good signal on most channels, even all the HD ones. This morning 08.40am all BBC TV and Radio channels are breaking up badly on two different Freeview devices. The same applies to most commercial channels. Odd. Is Rowridge at low transmitter power temporarily after final step? If so, hopefully they will boost up to full power.

Anyone else got problems?

Signal level seems as usual here (Holton Heath, horizontal aerial), but we've lost SDN/COM4. Have tried retuning, including manually on C25. Anyone else having problems?

Just done the retune for Rowridge. Lost programs associated with Com5 on internal aerial. Move the aerial to vertical and hey presto all signals coming in with no variation as people move in front of the aerial. Excellent.
No problems with loft aerial but will move to vertical soon.

My channels appear to be OK so far after the final change, but I have got less than full signal on some of the COM channels. Here's my enquiry I sent to Digital UK on 7th April:

I note from your reception predictor that my probability of receiving the 6 muxes are currently 99,99,99,99,77,84 (and working well). But after the re-tune on April 18th this will reduce to 99,99,99,21,20,21. Are these figures correct? If so could you please explain why the figures are so much lower after the re-tune? Will I need to have my aerial turned to VP orientation to reliably receive the COM muxes after April 18th? Even with VP, your site still predicts lower than now. Thanks.

And their reply:

Thank you for your email dated 7 April regarding Switchover in Meridian.

Your postcode is PO8 9xx which means you are likely to receive your TV signal from the Rowridge transmitter which switched on 21 March 2012.

Our postcode checker predicts that there may be a less reliable digital signal for your postcode after the retune event because in some cases this can be due to interference from nearby transmitters, both in the UK and in neighbouring countries.

The mux reception on 18 April is only a prediction of variable reception on those three muxes. I would therefore strongly recommend you wait until after switchover to see if your home will actually be affected to avoid having unnecessary work done, i.e. realignment for Rowridge VP transmitter.

You would need to consult a reputable local aerial installer for advice on this option and that of course might incur a cost. If this is your preferred route, I would recommend that you use a Registered Digital Installer (RDI) identified by the 'digital tick' logo. To find a RDI in your area please visit:

If you have any further enquiries regarding the digital switchover please visit our website at or call us on 08456 50 50 50.

...So it seems to me that they've kept the power levels the same, but expect interference from France on the new channels. Now we see why they felt the need to introduce VP - they've given the clear channels to London!

Derek Green: Hi Derek...I'm way across the country from you in Haslemere, Surrey. I seem to have the same problems apart from Channel 27..ITV. I've lost 21,24 and the new 3 allocated COMS. The signals have been coming and going all morning since about 7:30 on all 5 freeview devices in my house. The signal strength is either 0 or 87%.(And in a few instances "Too strong" on channel 22) I am assuming that all is not going to plan at Rowridge. It's really frustrating that the weather is so bad today as well..difficult to assess whether it's Rowridge, weather or what!
