Channel Counter Operation - Yaesu VX-8DE 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-
8DR/DE close to the transceiver which is transmitting.
The VX-8DR/DE performs a high-speed search within a ±5 MHz range from the fre-
quency displayed on the LCD. When the strongest signal in that range is identified, the
VX-8DR/DE displays the frequency of that (strongest) signal, and writes it into the spe-
cial "Channel Counter" memory.
Note: This Channel Counter is designed to provide an
quency of the incoming signal, one that is close enough to allow the user 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.
The Channel Counter feature can only be activated while the VX-8DR/DE is
operating in the "A-Band".
1. Set the "A-Band" to the VFO mode in the predicted frequency range for the transmit-
ter to be measured, then set the "A-Band" to the "Operating" band (indicated in large
characters).
2. Bring the VX-8DR/DE into close proximity to the transmitter to be measured.
3. Rotate the DIAL knob, while pressing and holding in the
key, to select the "CH COUNTER" mode.
4. Release the
quency of the nearby station will be displayed. When the
channel counter is active, a 50 dB receiver front-end at-
tenuator 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
"- - - NO - - -" notation appears for two seconds, then the
transceiver will return to the frequency on which you were
operating when you started Channel Counter operation.
6. When you are finished, press the
operation.
