Digital Auto Mode - AOR AR-DV1 Operating Manual

WFM – Wide Band Frequency Modulation
Used by VHF and UHF broadcast stations because of its excellent audio quality,
this is available due to the relatively wide frequency bandwidth employed.
Used only for local services such as VHF band stereo channels.
LSB – Lower Side Band / A form of SSB (Single Side Band).
Not intended for commercial use but used extensively by Radio Amateurs on frequencies below 10 MHz.
This assists in the separation of Commercial and Amateur users on traditionally shared bands and
prevents them from speaking to each other.
SSB is a very efficient method of transmission as the unwanted second sideband and carrier have
been removed. This allows the full transmitter power to be employed in carrying useful information
within the wanted sideband. As a result, greater distances are possible on SSB and a smaller
frequency bandwidth is required than with most other modes.
USB – Upper Side Band
The same comments apply as for LSB. By convention, Radio Amateurs also use USB above 10 MHz.
CW - Continuous Wave
Also referred as Carrier Wave or Morse Code.
Commonly used on the shortwave bands by Radio Amateurs toward the lower end of each band
allocation. Some commercial use is still made by shipping etc. although its use is being phased out due
to the introduction of automated stations.

3-6-1 DIGITAL AUTO MODE

When in auto mode, receive mode is set to FM and the receiver will automatically detect and decode
digital voice transmissions.
(For a worldwide directory of D-STAR repeater frequencies (classified by country and city), you may want
to check the very informative D-Star Repeater Directory site at: http://dstarusers.org/repeaters.php )
To activate auto mode, press the [MODE] key and rotate the dial knob to select "AUTO" in the reverse
contrast on the bottom of the LCD.
