Anybody have any idea who is on 150.200 - Units go by "Defender" with a number - also after each transmission ends the word "BLACK" is sent in morse code - my only guess is maybe the Army Air National Guard out at the Stead Airfield or maybe the Air National Guard here at Reno Tahoe International but they usualy identify with "RYAN" as they are also on our channels on the Washoe EDACS System
