There's a post by Simon Pryce at Does your Freeview EPG have nothing in it? | Knowledge base | free and easy I thought I'd link here in case you don't see it and is of interest.

Simon Pryce:
As you've put your post on a Freeview page, I've put a link to it at All of the free TV channels on PGSTART1500 in the UK | free and easy as there's often a few posts about satellite over there, and a couple of posters that post there occasionally might be interested or have something they can add.

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.

Mr Philip Black:
The Freeview Coverage Checker suggests you should get very good reception of all the multiplexes. The Horor Channel 68 is carried on the SDN multiplex, so you ought to have problems with other channels on that multiplex if it were a reception/interference or cable/connection problem.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.
Apart from following the suggestions already given by StevensOnln1, also check you don't have any HDMI cables runn9ing close to your aerial or flyleads, as HDMI has been known to cause interference.

C Fraser :
Can't find any reports of problems at the Black Hill transmitter by Freeview or the BBC, nor is any Planned Engineering listed, assuming that's the transmitter you are receiving. You might be receiving a Relay or another Main transmitter, in which case a full postcode and which way your aerial is pointing would be needed to offer further advice if the problem is still continuing.
Check you are correctly tuned to the Black Hill UHF channels, see Black Hill (North Lanarkshire, Scotland) Full Freeview transmitter | free and easy

Brian :
If it's an omni-directional aerial then it doesn't need "pointing". Does the aerial have clear line-of-sight in all directions or is it obscure by buildings or trees in any particular direction?
One predictor suggests you would have only "fair" reception of BBC Radio Nottingham, whereas the BBC one suggests you should have good reception.
There are four nearest transmitters to you, and one further away, not all carry all multiplexes.
The transmitters carrying the Local multiplex with BBC Radio Nottingham which is on Block 12C: 227.360 MHz, from you they are to the NE (Fishpond Hill) and SE (Nottingham but also further away slightly more to the E of SE is Mapperley Ridge). Whilst you are just within the service area according to Arqiva, some locations around you could be patchy.
The transmitters carrying the Local multiplex with BBC Radio Derby which is on Block 10B: 211.648 MHz, from you is to the WNW (Bolehill) and SW (Quarndon). I'm guessing that the Smooth "Leicestershire" you are getting is on this block - one list says Smooth East Midlands (seems to be for Leicestershire and Derbyshire).
If you are getting stations such as Absolute 80s and 90s, Boom, Jazz FM, Scala, Talk radio, Union Jack etc. these are on the SDL multiplex Block 11A: 216.928 MHz (some are DAB+) this multiplex is only broadcast from Mapperley Ridge.
The Local multiplexes generally can be lower power than the main ones, try manual tuning for the various blocks, auto-tuning can sometimes miss weaker ones.
Whilst your aerial will have no gain (being presumably a dipole) and theoretically no directional properties, the way it's mounted on a pole could affect that. Apart from making sure it has line of sight in the required directions and is reasonably high, if the pole is behind the whole length of the aerial it might act as a reflector giving direction properties in the opposite direction, so you might need a bit of experimentation if this is the situation and can't get the multiplexes by manual tuning. Other aerials very close could also have an effect.

Tony Ling:
And presumably now just called Capital South with opt-outs for Brighton and Hove.
The site owner hasn't has time to do many of the changes that have taken place in recent years.

Tony Ling:
To add to which, I guess it's no longer on the trial multiplex on Block 9A: 202.928 MHz and is now on a Sussex Local multiplex on Block 10B: 211.648 MHz maybe still calling itself Capital Brighton when it has opt-outs?

Russell Cobban:
Can't find any reports of faults listed by Freeview or the BBC, and the transmitter isn't currently listed for Planned Engineering.
Check that you are correctly tuned to the UHF channels for this transmitter (as listed above). Check all your connections and that the aerial is pointing the correct way (also vertical polarisation). There is another Relay transmitter close by - Dunkeld Town which is even lower power - UHF channels C23, C30, C26 for PSBs1-3 and in a different direction.
Post back with a full postcode and which way your aerial is pointing if problems continue.

James Bolon:
You've posted on the DAB transmitter page rather than Freeview, but not to worry.
The Sony Channel is carried on a Local multiplex and there is no Local multiplex transmitted from the Heathfield transmitter.
See Channel listings for Industry Professionals | Freeview for which channels are on which multiplex.
As you haven't given a full postcode, I can't advise which transmitter(s) you might be able to receive which may/may not have a Local Multiplex, or which way the aerial should be pointing for best reception.
