Glen: Pop is carried on the local TV multiplex, which is not broadcast from Sandy Heath but is broadcast from the Madingley transmitter which is in the same direct as Sandy Heath for viewers in Cambridge. If you can receive a local TV station on Freeview channel 7 or 8 then you should also receive Pop on 206, Tiny Pop on 207 and Pop Max on 208.

Glen:
With the changes on July 19th, all 3 Pop channels are now carried on the Local multiplex as mentioned by StevensOnln1.
The Local multiplex is beamed in an easterly direction from the Madingley transmitter (towards Cambridge). Unless you fall within that area you won't receive them unless you are quite close to the transmitter. Try a manual tune on UHF channel C35 for the Madingley Local mux as autotunes can sometimes miss weaker signals.
There is a Pop Player which moved with the changes to LCN212 and is carried on the SDN multiplex but it's a streamed service, so you need a Smart TV. Before it moved you could choose a selection of Pop shows, but LCN212 now seems to be "Pop Kids" (unless it changes at different times of day.
However, the Pop Player accessible via LCN100 on Freeview Play (Smart) TVs gives you a whole variety of choices but your "smart" device needs HbbTV functionality to access LCN100 (if your set has it make sure it's turned on in the TV settings).
Now you may also be able to access this Pop Player via you set's App menu - via "Explore Freeview Play" and it doesn't need HbbTV! or even load the App separately from your set's App store.

sandy heath com5/c36 seems particular pixelated unwatchable 13/08/23.(12th too)
are there no details on what specific engineering work is happening on Sandy Heath (per previous post) or how long this will last.
Atmosphere problems can obviously impact reception too, so detailed information would help customers identify cause.
just seems unprofessional not to provide/link details

paul :
Just to add, Arqiva & Freeview never provide details of what the work entails or how long it will last (some of which may be weather dependant).
It looks as though Sandy heath will still be listed next week as well.
(PS. I tend to agree with about the lack of some further detail).
