Channel Counter Operation - Yaesu VX-3E Operating Manual

C C
HANNEL
The Channel Counter allows measuring of the frequency of a nearby transmitter, without
knowing that frequency in advance. The frequency can be measured by bringing the VX-
3R/E close to the transceiver which is transmitting.
The VX-3R/E performs a high-speed search within a ±5 MHz range from the frequency
displayed on the LCD. When the strongest signal in that range is identified, the VX-3R/E
displays the frequency of that (strongest) signal, and writes it into the special "Channel
Counter" memory.
Note: This Channel Counter is designed to provide an indication of the operating fre-
quency of the incoming signal, one that is close enough to allow the user, thereafter, to tune
precisely to the other station's frequency. This feature is not, however, designed to provide
a precise determination of the other station's frequency.
1. Set the radio to the VFO mode in the predicted frequency range
for the transmitter to be measured.
2. Bring the VX-3R/E into close proximity to the transmitter to be
measured.
3. Rotate the DIAL, while pressing and holding in the [ MODE ]
key, to select the "CH CNT (Channel Counter) mode."
Note: Do not forget to pull the DIAL knob to rotate the DIAL
knob.
4. Release the [ MODE ] key to begin the Channel Counter; the fre-
quency of the nearby station will be displayed. When the chan-
nel counter is active, a 50 dB receiver front-end attenuator will
be engaged. Therefore, only stations in close proximity may have
their frequencies measured using this feature.
5. If it isn't possible to determine the signal's frequency, the trans-
ceiver will return to the frequency on which you were operating
when you started Channel Counter operation.
6. When you are finished, just press the [ MODE ] key. The radio will exit from Channel
Counter operation.
