So, from Broomfield I'm hearing very odd activity on 852.5125, 156.7 PL. It sounds like a fire crew with air masks talking about how to build a "pyramid" with "Leggos" of various colors. Several units mentioned they were "going to rehab", and I'm a hearing a lot of references to the "Charlie side", "Alpha side" and "Bravo side", which is obviously Fire-speak. It's a bit difficult to hear, because someone else is "walking over" this radio channel. I heard the interference myself, and a unit could also be heard complaining about interference. Also, while scanning through all the Federal Interop. channel's I just heard morse code tones on 851.01250/156.7 PL. Anyone know what I might be hearing??
