UHF Radio Control Panel

The aircraft communications system consists of a Have Quick UHF radio, a VHF radio, a secure voice control panel and an intercom set. Using the UHF radio control the frequencies (225.00-399.975mHz) are selected, if not done via ICP and DED. Many pre-selected frequencies can be selected via a channel selector, as well as the GD (Guard Frequency 243.00mHz). The panel is only active, if the CNI switch (CNI=Communication, Navigation, IFF) on the Auxiliary Control Panel is at the BACKUP position. The UHF Radio Control Panel is located on the left console.

Preset ChannelRotary1 - 20Permits the selection of 1 of 14 preset frequencies (channel 1-14) with the mode knob at PRESET and the A-3-2-T knob in A and the mode knob in 2 or 3. With the A-3-2-T knob in A and the mode knob at PRESET, the preset channel knob permits the selection of one of six preset WOD (Word-of-Day) frequencies (channel 15-20)

TONEButton Depressing in normal or AJ (antijamming) mode will interrupt reception and transmit a tone signal and TOD for HQ (Have Quick) on the selected frequency. Simultaneously pressing the TONE button in conjunction with the A-3-2-T knob in T position starts the emergency startup of the TOD clock.

Button-Set WOD (Word-of-Day) in flight. For a new WOD frequency entry, start at channel 20 and use the same method as in entering preset frequencies in the normal mode. The WOD frequency is set with the manual frequency knobs and the PRESET button. After a brief pause, a single or double beep tone is heard in the headset indicating that channel 20 is entered into preset memory. Channels 19-15 are selected in that order for preset frequency entry.
