This is my third Airline 77
I bought the new Samson Airline 77 wireless mike to replace a well-used 7 year old Airline 77. I really appreciate the BANDH associate explaining the new frequencies - the existing ones will no longer be used for consumer wireless microphones in about 3 years. He also told me where to get the supporting FCC information. The first Airline 77 became obsolete in about 2010 when FCC no longer allowed these mikes to operate on the current frequencies. The Airline 77 headset mikes are rugged and have never failed me - and and have served me well. BANDH has been my go-to source for camera and electronic equipment for many years and will remain so.
