Channel Counter Operation
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-7R close to the transceiver which is transmitting.
The VX-7R performs a high-speed search within a ±50 MHz range from the
frequency displayed on the LCD. When the strongest signal in that range is identified,
the VX-7R 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
frequency 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.
1.
Set the radio to the VFO mode in the predication frequency for the transmitter to
be measured.
2.
Bring the VX-7R into close proximity to the transmitter to be measured.
3.
Press the [MON/F] key, then press the [7(CH.CNT)] key to activate the Channel
Counter, then frequency of the nearby station will be displayed. When the channel
counter is active, engage the 50 dB receiver front-end attenuator. Therefore, only
stations in close proximity may have their frequencies measured using this feature.
4.
When it isn’t possible to determine the signal’s frequency, the transceiver will
return to stating frequency of the channel counter operation.
5.
Press the [V/M] key. The radio will exit from Channel Counter operation.
Setting the Channel Counter Sweep Width
You may change the bandwidth of the Channel Counter. Available selections are ±5,
±10, ±50, and ±100 MHz (default: ±50 MHz).
Here is the procedure for selecting the Channel Counter Bandwidth:
1.
Press the [MON/F] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL to select Menu Item (Scan Modes #1: CH COUNTER).
3.
Press the [MAIN] or [SUB] key to select the desired bandwidth.
