I was trying to gather some information on the Naval Support and Carlisle Barracks Astro systems in Mechanicsburg. I found three control channels but was unable to get Unitrunker to decode any of them. I tested the operation of my setup by decoding the Carlisle Borough and Lower Allen Type II systems. I tried inversion both ways but didn't have any luck. I will try to post wav recordings of the control channel for everyone to listen to. Thanks for any help in advance.
