Many of the military services worldwide have been consolidating their HF communications services into joint systems. Here in the U.S. DoD consolidated many JCS HF nets (i.e. Navy HICOM etc) into the HF-GCS network. In the UK several older networks have now been combined into the RAF TASCOMM.Now we have another national military service net which has consolidated several service nets into one. The Australian and New Zealand military services now have one network known as the Australia Defense Force (ADF) High Frequency Communications System (HFCS) with the main station located at Canberra. They have seven main HF voice frequencies that carry the bulk of their voice comms listed below.
ADF-HFCS Voice Contact Nets (VCN) "Australia Control"
3700.0 kHz / 0900-2100Z / VCN-1
5878.0 kHz / 0900-2100Z / VCN-2
9340.0 kHz / H24
10212.0 kHz / H24 / VCN-4
12172.0 kHz / H24 / VCN-5
20632.0 kHz / 2100-0900Z / VCN-2
22868.0 kHz / 2100-0900Z / VCN-1
They also have an extensive list of HF discrete frequencies. You can learn more about this system (including their registered discretes) on the Shortwave Listeners Delight website at
