Keith Farrington: Since it sounds exactly like single source interference, why would you reject that possibility?
In the meantime, at least check all your cables - if they are poorly shielded, etc, then that will make the problem much worse.

June Huertas: What do you actually mean by 'interference'? You might want to check which transmitter you are actually on, and we need to know what your postcode is.

Keith Farrington: If you have a look on the webpage for 'single source interference', someone had the idea of using an radio to track down the problem.
See if that can help, because if you at least know what direction the problem is, then you are closer to tracking it down. And if its external, at least you can ask neighbours, etc.

mick: 23km from the transmitter? It sounds like a problem with the aerial system. Check signal strength, and note when there is a big change in signal strength either way. A sudden lose of signal could be due to interference, or water getting into the system after heavy rain.

John: Why are your blaming individual problems with reception, which is quite likely to be caused by faults within your own system, on Freeview?
If your getting a weak signal, check your system, because thats the most likely cause - your system.
The location of transmitters, geography and the basic physics of how a signal gets to the household has not changed one jot from analogue, and the power output is roughly the same.

peter rance: Check your signal strength. Humax have sensitive tuners, and so if your getting too strong a signal (80% plus), then you will get breakup. Thats easily sorted.
If its too weak, then at least you can narrow down the possible causes.

peter rance: 81% is too high, as you can see if you look at the page 'too much of a good thing'.
Thats why you have a problem - every so often the tuner is being overwhelmed by the signal strength and breaking up. Its not a fault with the PVR (and anyway, its only Panasonic and Humax that really supply PVR's these days) but simply a need to damped down the signal a little.
I use fixed strength attenuators which I bought off Amazon, which can be fitted together to cut the strength by a varying amount.

Ron lake: I couldn't tell you about the sound (how are you outputting it?), but since your just 18km from the transmitter, I'd suggest looking at the 'too much of a good thing' page, because thats exactly the symptoms of too much signal strength.

Paul: Are you tuned to the correct transmitter? I'm on Waltham, and they seem fine. And no, there has been no change in power.

nick horrex: Can you really imagine the commercial broadcasters wanting to put their full range of services on a transmitter that serves less than 10k households?
Freesat, methinks.
