Hi folks and Happy New Year!

Location: RH13 9BG, Transmitter: Midhurst. Rooftop aerial (C/D). Setup has been working fine for years. Aerial seems to still point the right way, booster amp in loft appears to be working.

We experience Freeview issues since just before Christmas. Reception is good for most channels (incl HD) and fair on ARQB (CH50) and ARQA (CH59), but ... in sunshine only! As soon as it gets dark or even just cloudy, usually strong channels pixellate and have chopped sound and weaker ones show 'no reception or scrambled signal'. My Humax (HDR FOX T2) shows signal strengths around 30% and quality around 10% (watchable threshold is above 40% quality) on channels 50, 54, 55, 56, 58 and 59.
In sunshine, signal strength exceeds 50% & quality is typically above 70%. Similar results seen on Sony and Samsung TVs' internal tuners.

Any/all suggestions for diagnosis or fix welcome.

Many thanks in anticipation.

Thank you for your speedy reply. Sorry I missed it initially, the "Email me Updates" setting appears inoperative.

I've managed to fix the issues after some research (via Google) about "Signal vs Quality". Turns out that our Signal is pretty much steady but Quality varies unpredictably. Given that it is predominantly Quality that counts (the receiver's ability to 'read' the encoded data stream from within a given signal), I viewed the booster/splitter amp in loft with renewed suspicion. If that rather antiquated beastie is introducing more noise than expected, the quality would be poor. I secured a replacement device, which also included a 4G filter as a bonus. Installation meant switching the cable-ends to F-plugs. As none of the Midhurst channels fall into the 800MHz range, I figure the 4G filter isn't (yet) needed, so I guess the old amp had just failed in some way.

In any case, after a re-tune, the Humax now reports Quality readings at 100% for all channels.

Thanks again for taking time to reply.
