| The system has needed a major upgrade for a couple of decades or more. What often happens with Amateur Radio, is what was temporary becomes permanent. The VK6 WIA news link system grew and adapted to doing more and more, and due to these changes was based on the original "design" that was not meant to do what it does today. |
| The VK6WIA news originates on 2M FM and is
transmitted to VK6RAP 2M on 146.100 MHz and outputs the news on 146.700
MHz. This repeater also provides feeds to... VK6RAP UHF VK6RAP 6 metres RF feed on 146.300 MHz to Mt.William RF feed on 438.525 MHz to Mt.Saddleback Time out inhibit and CW identification is also removed from all these repeater systems during the news broadcast. The news interface box shown below in gray is the control unit that takes the received signal from VK6RAP 2 metres and inhibits time outs and cw idents on all other repeaters transmitting the broadcast from Roleystone. Some of the circuits below require re-drawing, as there is duplication that adds confusion to the understanding of how the WIA news system works. This is being done. |

| The Circuit above shows the connection
between the equipment that makes up the VK6 WIA news system at
Roleystone. VK6BBR is included as it has (had) a re-boot facility from
the DTMF Decoder but is not of course part of the VK6 WIA news
broadcast facility. The news is received on VK6RAP 2 metres on 146.100 MHz, just as a normal OSQ. What makes it different is CTCSS tone encoded on the news transmission into VK6RAP 2 metres that tells the news interface circuit that it is a news broadcast. The CTCSS tone does many things.
