Been listening to pulse 2 and radio Leeds on my dab radios for many years and suddenly on Sunday 28th I lost them both on 4 of my radios and cannot get them back despite rescanning. Anyone got any idea why I should suddenly lose these stations

On the D1 National multiplex (Roberts Stream 94i radio on DAB, 222.064 MHz) on Classic FM I am getting odd background noises. Sometimes it sounds like high speed skating, sometimes like a slightly delayed double speed version of the music breaking through, sometimes like a high frequency mechanical resonance or buzz with the occasional high frequency twang even at 5 of 5 bars or 90%+ signal. It doesn't occur during speech or singing. When the music is relatively quiet then there's far less chance of background noise. I got this on Friday 14th May and the next day. Similar music on BBC Radio 3 on BBC National DAB does not have this problem. Scala Radio on SDL National however has the same problem. The background sound seems to be largely in the stereo difference signal and appears on Joint Stereo radio channels and not on full stereo (e.g. Radio 3) channels. Re-scanning does not help. The problem is far less pronounced on my older Robert EcoLogic 5 DAB radio. Internet Radio just does not have these problems.
Is there anything that can be done about this?

John Yeadon:
My initial thought was weak signal, often some of those sorts of noises occur more when it's a DAB station rather than DAB+ and both Classic FM and Scala are DAB. In my experience the noises are much more pronounced when the signal is right on the "cliff-edge". Try moving your radio to a spot which has a clearer line of sight to the transmitter when you are experiencing this and see if it changes.
There aren't that many transmitters that transmit the SDL multiplex, AFAIK in your general area it's only Emley Moor but there may be a number of other transmitters that you can get the D1 and BBC multiplexes from, maybe even a Local multiplex, but can't comment on that without a full postcode.
There aren't any reports I can find, that show any faults affecting multiplexes carrying BBC stations, the BBC don't report on the purely commercial multiplexes and I've yet to find any page from Arqiva giving details of faults or transmitter maintenance!
Your problem is likely to be due to engineering by Arqiva with the transmitter on reduced power.
I wasn't aware that R3 can also use joint stereo until I went looking but it most likely does this when R4Extra and R5Extra are on air. How the difference in compression might change the noise when the signal is weak, I don't know.
If the problem persists try emailing radio@arqiva.com and see if they can tell you what is going on.
