A typical incoming serial tone signal will cause an increase in radio line out by 25db regardless of
actual S meter reading for an audible by ear signal. The capture below depicts an MS110A
300bps signal from a Micom transceiver using its 3kHz data filter (into a dummy load), while the
FT-890 receiver output displayed is -55db. The actual S meter reading from the MS110A signal
transmitted at a power level to cause and audible signal registering around S0 and MS110A
signal transmitted at power levels to reach an S9 had no effect on the amplitude of the receivers
fixed port output displayed. As can be seen, 3kHz on transmit using the 1800Hz PSK Carrier is
out of band.
