Ramsey ABM1 Aircraft Monitor
Monitor the entire 118-137 MHz civilian aircraft band at once, and there’s no oscil-
lator that could cause navigational interference on an aircraft! High sensitivity brings in all
VHF aircraft signals within miles with no visible antenna (the ear bud cord is its antenna)!
Adjust the volume to comfortable listening; set the squelch to limit distance; wear the
inconspicuous monitor on a belt or in your pocket. Ideal
for air shows, airline trips, air traffic monitoring.
Measuring only 2-1/2” x 4-1/2”, the Ramsey
ABM1 Aircraft Monitor runs off a 9-volt battery (not
included); full operational/technical manual and privacy
ear buds are supplied.
