John from Woodbine lamented on one of the forums as to what happened to those "Golf" callsigns that disappeared off 507Mhz some time back

I think I have found them or similar - "green" call welfare checks every hour during non-business hours

Callsigns:
Control
Charlie 2,10
Golf 3,5,6,7,8,9,10,11,15,16,16A,17,17A,19,21,25

Charlie callsigns appear to be mobile supervisors
Golf appears to be Security Guards, some static, some mobile

Incidental Conversations would go like this:

This is Golf 21 - off at (location) Lima 14
This is Charlie 2 - off at (location) Golf 3 (assuming Golf 3 is a static guard)

With Security firms I enjoy the challenge of listening to and decoding all the code that they attempt to use in masking who, what and where

For further information on monitoring security see my short net article at

Lots of security frequencies listed there (heaps more to find too)

Hi Grant,
I had 486.700 listed,they were doing radio checks at 9pm with golf callsigns,it was unusual that the 507mhz frequencies went dead.
The only other one that is very active every night in Sydney is Nycon on 470.875 (st 162.2).
Otherwise I have been monitoring the security companies on 800mhz trunking off GPT,Suncorp tower & Horlsey Park.
Regards, John.
