Dave Lindsay: Thanks for your idea. I've replaced every cable between wall socket and TV, and also swapped out signal booster for another one just in case - same result.
It will have to wait until tomorrow before I can get in to the loft to see if there's any cable to replace there - my digital aerial goes into a multi-switch to distribute satellite and freeview to multiple rooms. I've powered that multi-switch off/on but that's not made any difference.
Given no one else here has stated issues with Midhurst transmitter, it's clear it's something on my end. But what, I'm not too sure....
Problem is I need the signal boosters on C54, C59 and C50 as without them I don't get sufficient signal to watch TV normally anyway. Only the more powerful transmissions get through without the booster (and indeed signal strength doesn't increase with booster in line for C56 for example).
Thanks anyway - I'll keep trying to diagnose the local issue, but when it's daylight again !

Dirk Gently: Woke up to find Midhurst is now all working again. No changes made on my equipment after my last post yesterday, but C54, C59 and C50 are now all watch-able again.

Midhurst - all transmissions on 10,000W muxes not receivable. Those on 20,000W muxes mostly okay, with C55 the only mux that's got no issues. Seemed to go off overnight, perhaps due to storms or perhaps around time when engineering work was going on with DAB.
Full reset of all kit and re-tune hasn't helped. Checked aerial and all looks okay.
Plugged in DVBT card to computer to see what it thinks about mux output.
C55 (746.0MHz) 20,000W - all channels fine. No uncorrectable errors in transmission. Quality 58 out of 60
C56 (754.0MHz) 20,000W - all channels fine. 1 to 3 correctable errors per 5 seconds. 1 or 2 uncorrectable errors per 10 seconds. Quality 55 out of 60
C58 (770.0MHz) 20,000W - can't comment as don't have DVB-T2
C54 (738.0MHz) 10,000W - can't view any channels, 1000's of errors per second. Quality 23 out of 60
C59 (778.0MHz) 10,000W - can't tune to - Quality 12 out of 60
C50 (705.0MHz) 10,000W - can't view any channels, 1000's of errors per second. Quality 24 out of 60
Either I've a local issue, or there's a genuine fault with the Midhurst transmitter since they finished the engineering works on DAB last night.
