Simon: Just out of interest, what do you mean by "reduced quality"?

I am now having some difficulty in receiving the group of services on channel 67, Sky News etc. The reception of this group was perfect until around a month ago, I have retuned and checked the aerial and all connections and everything is OK. All the other channels are still perfect. I only live around 8 to 10 miles as the crow flies from Sandy Heath, Post Code PE19 5LF. The aerial is wide band and medium gain. Any ideas please.

Briantist,
Thank you for the response. However nothing has changed in my home set up, all the equipment has been sitting there since the last re-tune, at which all channels were received without problems for quite some time. Until about a month or so ago the services on channel 67 all come up with low or no signal, I cannot see how this can be single channel interference.

Pete: OK, given that C67 previously had ArqB and since 14th September 2011 has had ArqA, it would be quite important that you did this My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice to reset the box.

My mother lives in Toft, Cambridgeshire CB23.
We are getting signal from Sandy Heath.
We can pick up Dave on Channel 67 - all OK.
However, when the box decides to check for new channels, it detects a "better" Dave on channel 52 (which I understand it it moving to at end of November). Any ideas why her box thinks it has already moved?
