64 FT-1802M OPERATING MANUAL
FM BANDWIDTH & TX DEVIATION LEVEL
You can reduce the receiver bandwidth and microphone deviation level when operating on
tightly-clustered frequencies (channel spacing of 12.5 or 15 kHz). This will reduce the trans-
mitter deviation, thus minimizing interference to other users.
To configure for the narrower bandwidth, use the following procedure:
1. Press and hold in the
[
MHz
(
SET
)]
key for one second, then
rotate the DIAL knob to select “59 W/N DV.”
2. Press the
[
MHz
(
SET
)]
key, then rotate the DIAL knob to
change the display to “NARROW (±2.5 kHz Deviation, 6
kHz Bandwidth)”.
3. Press and hold in the
[
MHz
(
SET
)]
key for one second to save the new setting and exit to
normal operation.
4. To return to wide bandwidth and deviation, repeat the above procedure, selecting “WIDE
(±5 kHz Deviation, 15 kHz Bandwidth)” in step 2 above.
MIC GAIN SETTING
At the factory, a microphone gain has been programmed that should be satisfactory for the
supplied MH-48A6J Microphone. If you use an after-market microphone or connect a TNC,
you may wish to set a different Mic Gain level, using Set Mode item “27 MCGAIN.”
1. Press and hold in the
[
MHz
(
SET
)]
key for one second, then
rotate the DIAL knob to select “27 MCGAIN.”
2. Press the
[
MHz
(
SET
)]
key, then rotate the DIAL knob to
set the desired level (Default: LVL 5).
3. Press and hold in the
[
MHz
(
SET
)]
key for one second to save the new setting and exit to
normal operation.
Remember to readjust the default microphone input level to “LVL 5” when using the sup-
plied MH-48A6J Microphone.
