KAFW / 52F revised feed setup
« on: November 23, 2014, 01:58:20 UTC »
Moved KAFW feed from my home 8.5 miles from the field to a friend's home overlooking the airfield.  Also switched over to a Raspberry Pi with two Griffin iMics sent fully configured (thanks, Dave!).

Revised setup has a stereo feed with KAFW tower in the left ear/speaker and Regional Approach/Departure in the right ear/speaker, as well as independent mono feeds of each (thanks to some scripting magic on the LiveATC server side).

Clearance Delivery and Ground are also covered.

Also hosted from this location is a discreet 52F (Northwest Regional) frequency.  52F is just outside the class D to the Northeast of KAFW, and is a very busy general aviation field under the DFW Class B shelf.  Traffic departing / arriving 52F often contacts KAFW's tower for transit of the Class D.

Oh, nice. Are all 4 scanners sharing the same antenna ? How is this done?

Thanks! Kai

They are using a 4-way RF power splitter from Mini-Circuits.  Similar or identical to this one:
