[TheList] Auckland air Traffic control

Mon Apr 12 15:38:42 AEST 2010

Thanks Neil..  I have plenty of scanners but outside Auckland Area.  I live in Dunedin and not much traffic down this way so I thought it maybe easy with a dish and receiver.  Never mind I will keep listening to atclive.net on my Itouch.  I wish someone in Auckland would put Auckland ATC on atclive.  Not sure what the legal ramifications are.  Someone in ChCh had Chch on for a while but no longer bugger
Thanks again

You connect a scanning receiver to the port on the splitter that is DC isolated to prevent the power to the LNB damaging your scanner.

You will need to find out what frequency the Local Oscillator actually is to calculate what frequency your scanner needs to tune to. Then again it's going to be changing with temperature drift etc.
