I see that you are in the UK, but your post seems very confused, referring as you do to "Radio Littleham" ("Littleham Radio"?) and then giving an example with the callsign "Littleham Ground" which is an ATC callsign. And you were giving a lecture on the "correct use of radio"!
The sooner the the CAA gets its act together in addressing the AGCS issue, the better, preferably either getting rid of A/G stations and making them either Safetycom or obliging them to upgrade to FIS.
