What about when you try and follow the SOP's and not use the MFS allocated number (8624, 2912 etc) but you use your CFS callsign "nuff nuff 24 Pumper mobile to ....", then the MFS comcen dude calls you back with "roger 8624 you're K1".
Not to mention that nuff nuff 24 Pumper should actually be 861 (first Pump) and when nuff nuff 24 responds as well - MFS still call it "nuff nuff 8624" so all of sudden MFS have two 8624 appliances going to different jobs - yes it is as confusing as what I have just said.. If you have ever heard Seford call up on the radio they always say "Adelaide Fire this isSeafood 24 Pumper mobile to ......" then MFS call them back with "Roger 8334 you're K1". Well Seaford don't even have a 34, MFS just don't get it.
I think they play games with us, either we should all use MFS appliance number (2919, 9219, 9119, 9419, 8334, etc) or no one uses them, and the MFS comms guys acknowledge that we aren't using them and just respond to us with our standard CFS callsigns, rather than responding to us on the radio with the MFS appliance nubmers.
