UL-800 with External VDR
The VHF VOICE page is used to enable/disable VHF voice mode.
LSKs [1R] and [2R] allow selection of the MODE as either DATA or
VOICE respectively (an asterisk <*> indicates the selected mode).
DATA Mode - UniLink data communication; no voice communications.
UniLink will tune to the appropriate datalink frequencies only.
VOICE Mode - UniLink no longer communicates via VHF to support
datalink communications. The external VDR is used for voice and
voice frequencies are tuned via VOICE FREQ, LSK [3L].
VHF voice frequency can be tuned from this page if Voice Frequency
Control enabled in configuration. Valid frequency range is:
• If configured for frequency spacing of 25KHz - 118.000 to
136.950
• If configured for frequency spacing of 25KHz/8.33KHz -
118.000 to 136.965 and 136.980 to 136.990
NOTE: The frequency 136.975 is a reserved frequency.
