YBBN : feed covers Brisbane controlled airspace. From clearance & tower to departures & centre. Here is a couple of pics of the simple setup providing the stream.
From the 3.5m dipole on the roof signal is fed to the ICOMA6 tranceiver that is set in scan mode. Then the signal is sent through a compressor/limiter to keep the different signal strengths and levels about the same, then the signal is equalised to optomise the 11kHz stream. From there is is sent across to a spare PC.
The PC is a spare on the network runing WinXP. Always up with an ADSL2 connection. Signal is fed to the PC running the OddATC client that feeds audio to LiveATC at 11kHz using a MP3 compression consuming only 16bps.
Not a lot to it and it seems to function efficently ...
