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-
6E close to the transceiver which is transmitting.
The VX-6E 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-6E
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-6E into close proximity to the transmitter to be measured.
3. Press and hold in the [
MODE
(
SP S
)
SQ TYP
] key for one second, and rotate the
DIAL knob while holding in the [ MODE
(
SP S
)
SQ TYP
] key
to that “
CH CNT CH CNT CH CNT CH CNT CH CNT
” indication appears on the display: this acti-
vates the Channel Counter feature.
4. Release the [
MODE
(
SP S
)
SQ TYP
] key to begin the Channel
Counter; the frequency of the nearby station will be displayed.
When the channel counter is active, a 50 dB receiver front-end
attenuator will be engaged. Therefore, only stations in close prox-
imity 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
(
SP S
)
SQ TYP
] key. The radio will
exit from Channel Counter operation.
