There is a problem developing with regard to chatter over the radio. 118.75 must be used for YMMB ATC/CTAF(R), 118.20 is a Multicom to be used when outside YMMB Zone, 123.45 MUST BE USED FOR CHAT.

It is also a problem that members are joining with less than adequate voice comms. 3.600 Kbps sound must be selected and a suitable microphone/headset should be used. Please ask for a radio check on joining the session. If you need help, use the briefing room. If you are instructed to stop using your radio, please do and obtain a radio check again after altering configurations.
