On my 5000T, a couple of days ago I watched a BBC4 recording from last weekend, which, about a third of the way through, started to exhibit the same problems I had with the FoxT2. Freezing then skipping and restarting.
Thankfully my attenuator arrived today and I've duly set it up. Surprising results.
I first filtered via BBC A and it took more turns than I expected to get it down to 93%-95%. Switched to a couple of others and they seemed okay. Then I tuned to a channel on ARQ B (yes the shopping channel - I'd tune it out altogether, only it carries Yesterday, Drama and Classic FM) that blasted out at over 100% still, so I turned it way way down. Finally COM7 HD - again still over 100% so I turned the wheel again.
I've now got a range of 80% to 95% - thing is I'm about 12-15 miles from Crystal Palace (and yes not picking up any other transmitters)
So they must have really increased the signal this early autumn, when my FoxT2 went on the blink....
Will check future recordings, expecially from COM7, and will duly report back. Annoying thing is the use of the OK button to switch to HD - which often happens accidentally - was also an issue with the T2 also so not new..
