Upon opening the top cover it's
clear
there are only three connections.
- Black = ground
- Red = positive voltage
- Green = Output Voltage
When a lab power supply (Agilent
E3617A)
is
used to slowly increase the voltage while watching the airwaves
for a
signal using a small antenna a signal appears when the input is at
about 3 volts and the ME-400 is drawing a milliamp or so. By
4.88
V the output frequency is at a minimum and increases slightly by
the
time the voltage is 5.0. There does not appear to be much
signal
strength change from 3 to 5 V so this box is probably designed to
run
from +5 V.
The operating frequency is in the neighborhood of 328 MHz but
varies
tens of kHz depending on what's near the ME-400 antenna.
