As there are now a few areas in the UK which have listening squawks (i.e. if you're in a Class G sector where a LARs is available but you choose not to talk to them, you can listen to their freq and disply their listening squawks, and they'll kno wyou're listening in case they need to contact you for whatever reason), it woul dbe very useful to have them displayed.

Maybe in the "Nearby ATS" section, have the names of the station together with the squawk like this:

Solent Radar (Listening Squawk 0011) 120.225
