I am missing a transmission multiplex?

^{Brian Butterworth published on UK Free TV 2nd October 2014 at 12:18}

If you are missing a single multiplex on a single frequency, it may be that you have a local source of interference - such as a VCR, games console or Sky Digibox - causing the problem rather than a poor signal from the aerial.

Try eliminating any such devices, and if one does appear to cause the problem, change it's RF output channel to a new value.

Hi Chris. Com4 and U&Dave went off again tonight at around 9pm. However, they came back on at around 9.30 with strength at about 90% but at 35-50%. Signal strength and quality have since gone back up to roughly what they were late last night and early this morning. I just wish I knew what was causing this dropout.

I also have the search box issue, so it's the site!

The last set of figures you posted are excellent. I think that proves beyond doubt that mobile cell is a primary problem here.

is currently on Planned , so there can be other variations in , so some of the "drop-outs" may be just that. U&Dave is on COM5/ArtqA.
It's encouraging signal returned at about 9.30. I think as you have now got some good figures, it's a case of watching what happens for a while.
Post the figures when you get any noticeable changes that persist for longer periods.
