Fm Bandwidth & Mic Gain Control; Microprocessor Resetting; Set Mode Resetting - Yaesu FT-1500M Operating Manual

2. Press the [MHz] key, then rotate the Main Dial knob to select the desired speed
(50/250/450/750/1000 ms).
3. Press and hold in the [MHz] key for one second to save the new setting and exit to the normal
operation.
Interface of Packet TNCs & Reset
The FT-1500M provides a convenient rear-panel DATA jack for easy TNC interconnections, Refer to
the graphic and table for pin-out connections.
Data rate selection (1200/9600 bps) can be selected via Menu "P RATE."
Normally, the microphone will be cut off during packet transmission, so as to avoid interference to the
data stream by voice input. However, this protection feature can be disabled, if you have some reason
to want the microphone to be active during packet transmission.
To re-activate the microphone during packet transmission:
1. Press and hold in the [MHz] key for one second, then rotate the Main Dial knob to select
"PCKT."
2. Press the [MHz] key, then rotate the Main Dial knob to select "MIC ON."
3. Press and hold in the [MHz] key for one second to save the new setting and exit to normal
operation.
To disable the microphone during packet transmission (the typical configuration), select "MIC OFF"
in step 2 above.
Packet operating procedures are governed by the software used by your computer and TNC. Consult
the documentation accompanying the software for details on packet operation.
FM Bandwidth & Mic Gain Control
You can reduce the microphone input level and transmitter bandwidth when operating on tightly-
clustered frequencies (channel spacing of 12.5- or 15-kHz). This will reduce the transmitter deviation,
thus minimizing interference to other users.
To reduce the microphone input level:
1. Press and hold in the [MHz] key for one second, then rotate the Main Dial knob to select "W/N
DV."
2. Press the [MHz] key, then rotate the Main Dial knob to change the display to "NARROW."
3. Press and hold in the [MHz] key for one second to save the new setting and exit to normal
operation.
To restore the normal (higher) microphone input level and normal (15 kHz) receiver bandwidth, select
"WIDE" in step 2 above.

Microprocessor Resetting

To perform a CPU master reset for all memories and Menu settings, press the [LOW], and [D/MR]
keys while turning the transceiver on.

Set Mode Resetting

To reset all Menu settings to their factory defaults, press the [REV] key and [D/MR] buttons while
turning the transceiver on.
Cloning
You can transfer all data stored in one transceiver to another set by utilizing the handy "Cloning"
feature. This requires a user-constructed cloning cable which connects the MIC jacks on the two
transceivers as shown below.
To clone from one transceiver to another, use the following procedure:
1. Insert the Clone Cable into the MIC jack of each transceiver.
2. Turn both transceivers off, then press and hold in the [LOW] key on each radio while turning the
power on again. The "CLN" notation will appear on the display.
3. On the "destination" radio, press the [D/MR] button.
4. Now, on the "source" radio, press the [MHz] key.
