I don't recall any of my boxes quoting a total number of channels at all!

Doug B: The problem for you is that Crystal Palace's early HD service is also using C31. CP is closer and this multiplex is transmitting at half the power of Sandy Heath SDN. The problem is expected to go away on 18 April 2012, when Crystal Palace completes DSO.
The Sandy Heath SDN retune to C51, mode change to 8K mode, and power up to final power level, is scheduled for 9 May 2012.

With reference to Doug B 's problems with C31, I also live in Harlow CM18 area and have good reception.
71% Signal Strength & 96% Good Signal Quality.
Just shows how hit and miss this Freeview reception is!

Main thing I noticed after the latest re-tune was the reduction in number of stations received, down from 173 to 103.

Re Lelpep: Best I got was 103 channels but as Briantist points out there is no standard for the way boxes report the number of Channels. My set tells me I am now down to 79, not going to count them though!
| link to this comment |
Lelpep: I count 99 listed at the top of the page, so add on Sky Sports 1, Sky Sports 2, ESPN and G.O.L.D and that's 103.
If you had a larger number before it was probably because you had not cleared your list before you scanned and "old duplicates" were being listed.

Lelpep: Worthwhile removing your aerial connection & scanning occaisionally. If you still have channels at the end of the scan you need to clear the list. Your manual will normally tell you how.

Doug B - There is usually a clear choice between scanning for additional new channels and scanning to replace the existing channels from scratch.
But the terms used for the choice vary a lot!

I have a satelite dish but no longer subscribe to Sky apart from the £20 (I think) I paid for Free View when the chap came around to change over my channels a few months ago. Now my 5 USA channels are not viewable, they are not stable. You simply cannot decifer them. What is happening?
