Hello Engineering, We Are suffering degrading TV with unwatchable reception here at PL68AW. Picture and voice transmission is continually breaking up and ibecomes unwatchable. Can you identify why this has occurred over last 48hrs. We never had this previously.
Look to your soonest reply.
Regards, KK

Kevin Kelley: This website is independant, no one on here has anything to do with transmitter engineering (those are automated posts of engineering notices provided by the BBC). The most likely explanation for your degrading reception is that something is wrong with your aerial system, such as a loose connection or water has gotten in to the cables. Start at the back of the TV and check all cables and connections are in securely and that there are no signs of damage, then work your way back as far as you can safely access towards the aerial.

bourchier:
To offer and advice we need a full post code so that we can examine the reception conditions at your location as it varies across the served area due to terrain and buildings.
It is just possible that the recent high pressure has created a natural effect often called tropospheric lift, or just 'lift, whereby the signals become temporarily variable and unreliable. That would give the effect you are describing.
Please check your signal strengths, they should be between 50% and 85% for SD channels and between 60% and 85% for HD channels. If you have less then you need to examine your aerial system for poor connections, etc. If they are over 85% then you have too much signal and need to fit an inexpensive attenuator.

bourchier: There are no faults showing for either Plympton or Caradon Hill (both transmitters show good coverage for your location). Start by checking all the cables and connectors behind the TV for anything that become loose or damaged, then work your way back towards the aerial as far as you can safely access.
