Thanks for feedback. Transmitter engineering notes appear to indicate TV digital working normally but analogue liable to interruption. Am I msiing something re freeview (digital?)?

I live in HP21 area and the Mux A channels have been unwatchable for the last few days. I'm not going to re-tune or do anything until the switchover has finished. Just thought I'd post this so others can see they are not alone in losing channels at the moment.

andrzej: Indoor aerials are poor for Freeview reception, and in an ideal world you should switch to using a rooftop aerial.
However, as switchover on the Oxford transmitter starts on Wednesday, you might want to wait.

Briantist. My postcode is HP21 9TZ. It's mainly ITV3 which is unwatchable and even sometimes shows no signal at all. It used to be fine so I have to assume it's something to do with the switchover as all my other channels are ok. I've got a new aerial, leads etc. I'll wait until the switchover is finished before I try anything else. Thanks for your response.

John J: Looking back across your old posts I think you may have gone overboard on the aerial, and something's overloading. If you have a booster, take it out. Try adding an attenuator.
If this *is* your problem it's about to get a whole lot worse, starting with Wednesday's power-up of the BBC multiplex.
Do also check that your box hasn't selected Sandy Heath on C31 rather than Oxford C51. Some boxes have an automatic overnight retune feature that happily overwrites a careful manual tuning of the correct channels!

Hello Brian,
You used to show potential conflicts for co-channel interference, but this has now gone. I am in a multi-transmitter area and have two wideband aerials, one pointing towards Oxford, and the other to Sandy Heath. When Oxford switches tomorrow and later this month, I can see several conflicts as follows (some are existing, which already block signals from both the relevant transmitters):
14th September:
ch29: ArqB Oxford / D London
ch31: SDN Sandy / HD London
ch34: BBCA Oxford / C London
ch48: ArqA Oxford / ArqB Sandy
ch68: 2 Oxford / A Hemel
28th September:
ch55: ArqB Oxford / 2 Hemel
ch59: ArqA Oxford / B Hemel / D3+4 Luton
ch62: SDN Oxford / C Hemel
Could you please restore this facility, as it's really useful to see which signal is the strongest; for example both the Hemel and London signals are strong enough to cancel out Oxford at the moment, even though I have no aerial for London.
Talking of signal strength, both the London and Sandy signals are strong enough on BBCA / 1 and D3+4 / 2 to be picked up on the Oxford aerial, without signal break up!
Regards,
Nicholas
