From the (allegedly) offending airfield's website:
FizzydrinkMeat Radio is frequency is 1**.*** and is an Air Ground Communication Service (AGCS) and as such is NOT Air Traffic "Control". However, the generic term "ATC" is widely used as everyone seems to understand this abbreviation! Even XXX Radar, YYYYYYY, ZZZZZZZ, TTTTTTTT, PPPPPPP, etc., still call us on the phone and ask for "ATC"! Perhaps we should just use "AT"! We get numerous calls asking for us to correct the "C" part so before you write in again the answer is the same - all we can do is repeat the above!
