receiver will appear to be desensitized and weaker signals will be missed.
WFM – Wide Band Frequency Modulation
Used by VHF and UHF broadcast stations as 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 extensively used by Radio Amateurs on frequencies below 10MHz.
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.
ISB – Independent Side Band
Similar to SSB, however, 2 independent SSB signals are transmitted on the same frequency.
Decoded signals can be heard separately from the headphone jack on the front panel.
CW - Continuous Wave
Also referred as Carrier Wave or Morse Code.
Commonly used on the short wave 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.
AIQ – Analog IQ for DRM
New digital communication format for SW (Shortwave) broadcast.
Proper software and external hardware are required to decode DRM (not included).
3-6-1 AUTO MODE SELECTION
When in auto mode, the receive mode and tuning step size are automatically selected for you by the
AR6000 microprocessor.
