Figure 4 – The PABM1 Passive Air Band Monitor
The PAMB1 is powered from one 9V battery. Please use a 9V
alkaline
battery. Mount it as shown in
Figure 4,
making sure that you install it with the correct polarity
.
WARNING!
The PABM1 is not protected against reverse polarity! Always take care to insert the batter correctly
according to the designation of polarity (
⊕
and
⊖
) on the battery and the battery holder. A battery
which is placed in reverse will cause damage to the device.
Next, connect a pair of stereo headphones to the jack labeled “headphones.” Do not force the plug so as
not to unsolder the jack from the circuit board.
Turn ON the PABM1 by sliding the power switch towards the ON position. The green LED indicator should
turn on.
Adjust the VOLUME potentiometer to a comfortable level. At this point it is possible that you will hear
communications and ACARS bursts from aircraft in the vicinity. Since by its nature the PABM1 is a very
wideband receiver, you may hear nearby FM stations. If you are indoors, you may also hear powerline
hum and signals radiated by nearby digital devices.
