I un-mothballed a number of my old trusty-rusty Radio Shack PRO-2052 scanners for monitoring aircraft operations here in the valley.

With the new VHF/UHF multireceiver antenna setup, it’s very easy to have a number of scanners all running in parallel so that I don’t miss as many conversations and handoffs.

Here’s the stack of scanners: the top is ZAB (Albuquerque Center); the middle is Phoenix area TRACON; the bottom has both KSDL (Scottsdale airport) and KPHX (Phoenix Sky Harbor airport) in there so that I can monitor either or both.

I put different color LEDs for the display backlights. Yellow is top; orange is middle; red is bottom.
