Busy Channel Lock-Out (Bclo); Changing The Tx Deviation Level - Yaesu VX-8GR/GE Operating Manual

M
ISCELLANEOUS
The BCLO feature prevents the radio's transmitter from being activated if a signal strong
enough to break through the "noise" squelch is present. On a frequency where stations
using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting
their communications accidentally (because your radio may be muted by its own Tone
Decoder). The default setting for the BCLO is OFF, and here is how to change that setting:
1. Press and hold the m key for one second to enter the Set Mode.
2. Rotate the DIAL knob to select Set Mode Item 7: BCLO.
3. Press the m key briefly to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to set this Set Mode Item to "ON"
(thus activating the BCLO feature).
5. When you have completed your selection, press the PTT
switch to save the new setting and exit to normal operation.
To disable the BCLO feature, just repeat the above procedure,
rotating the DIAL knob to select "OFF" in step 4 above.
In many areas of the world, channel congestion has required that operating channels be
closely spaced. In such operating environments, it is often required that operators use
reduced deviation levels, to reduce the potential for interference to users on adjacent chan-
nels. The VX-8GR/GE includes a simple method of accomplishing this:
1. Press and hold the m key for one second to enter the Set Mode.
2. Rotate the DIAL knob to select Set Mode Item 32: HALF
DEVIATION.
3. Press the m key briefly to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to change this Set Mode Item to "ON".
In this configuration (HALF DEVIATION active), the
transmitter's deviation will be approximately ±2.5 kHz.
5. When you have completed your selection, press the PTT
switch to save the new setting and exit to normal operation.
The "normal" setting for the deviation (when this Set Mode Item is set to "OFF")
is ±5 kHz.
