Transmitter engineering: I have had rubbish Freeview TV reception from the Plympton relay transmitter for several days now, probably from about the time of the latest lot of engineering work, particularly on BBC channels. Is it possible something wasn't "plugged back in" or "switched back up" after this work?

Alex Hutchinson:

I'm not sure what's given you the impression that there's engineering work going on at present. There's none listed for Plympton or Caradon Hill. The BBC aren't currently listing any faults, but if a new one has recently developed, there may be a reporting delay because of the current covid-19 situation.
There was some Tropospheric Ducting around several days ago which may have caused reception interference, but that cleared up a couple of days ago.

In the meantime, I would check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the multiplexes shown in your TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

If you've done those checks and the problem remains on Monday morning, I'd give BBC Engineering a call on 03700-100123.

Hopefully you will have all your signals and programmes back now. The BBC have reported several issues at the transmitter throughout the day with a fault and essential engineering causing it to be off-air or on reduced power.
If you retuned at all when you had no signal, and haven't retuned since, you will need to retune again.
Retuning when there is no signal usually just clears all correct tuning resulting in the need for a further retune.
