frequency sublevel is used to control Have Quick time, to control SINCGARS coldstart, to manually
load Have Quick fill, and to control Have Quick and SINCGARS zeroize.
The TIME RSTRT option is used to restart the radio clock. To prevent inadvertent selection, this
option requires a double selection to start the radio clock. Touching TIME RSTRT option changes the
touch option/display to RSTRT ENABLE. Touching the RSTRT ENABLE option starts the radio
clock and returns the display to TIME RSTRT. If any option other than RSTRT ENABLE is touched
after touching TIME RSTRT the radio clock is not started and the display returns to TIME RSTRT.
The LOAD DAY option is used to load the Have Quick calendar day. Touching the LOAD DAY
touch option/display border highlights the option and enables calendar day entry by touching the
desired numbers on the keypad options (01 thru 31), verifying the new calendar day in the scratchpad,
and touching ENT. When the calendar day is entered into the radio a tone sounds in the head set.
Touching any other touch option/display removes the border highlight from the LOAD DAY option
and data entry is no longer available.

The ZERO option is used to erase the stored Have Quick word-of-day (WOD) and SINCGARS
transec data. To prevent inadvertent selection, this option requires a double selection to zero radio
data. Touching ZERO option changes the touch option/display to ZERO ENABLE. Touching the
ZERO ENABLE option zeroizes both (COMM 1 and 2) radios. The ZERO ENABLE option is border
highlighted for 2 seconds and the display returns to ZERO. If any option other than ZERO ENABLE
is touched after touching ZERO the radios are not zeroized and the display returns to ZERO.
The RTN option is used to return to the fixed frequency COMM sublevel.
23.3 HAVE QUICK SYSTEM
Have Quick is a slow hopping, UHF, AM line-of-sight jam-resistant voice communication system.
The operation involves coordinating and establishing communications nets. These nets have multiple
users that have the same ECCM information and are time synchronized. The nets are established and
operate with information for a specific word-of-day. The WOD is used to define the frequency hopping
pattern for that day. In conjunction with the WOD, a precise time-of-day (TOD), which is effectively
the net time synchronizer, is also required. The net number and type can be entered using the keypad
options. The three digits to the left of the decimal point are the net number and range from 000 to 999.
The three digits to the right of the decimal point represent type: .025 = HQII (NATO), and .050 = HQII
(non-NATO).
NOTE
The radios do not contain a clock. Time must be set during aircraft
preflight.
The principle functions available for Have Quick control are:
1. Anti-jam (AJ) mode and net selection,
2. Time synchronization including either the reception or the transmission of the TOD,
3. WOD verification and manual entry,
4. Zeroing WOD,
5. Training net control and manual entry.
23.3.1 Have Quick Menu From AJ Menu Fixed Frequency COMM Sublevel. Touching the HQ
MENU touch option/display while on the AJ COMM sublevel with a fixed frequency selects the Have
Quick fixed frequency sublevel (see figure 23-7). This sublevel initializes with no options selected and
displays a 1: (selected radio) in the scratchpad. This sublevel is used for manual fill operation.
The HQ TIME option is used to transmit or receive Have Quick time. Touching the HQ TIME touch
option/display border highlights the option and enables the use of the RCV and XMIT options. With
HQ TIME selected, touching the RCV touch option/display border highlights the RCV option until
time is received, or until 60 seconds has elapsed. With HQ TIME selected, touching the XMIT touch
option/display border highlights the XMIT option for 2 seconds and time is transmitted. The XMIT
option is not displayed if ADF is enabled (for the selected radio). The HQ TIME option remains border
highlighted until HQ VDAY, HQ WOD or HQ TNET is selected.

The HQ VDAY option is used to verify that a Have Quick word-of-day is loaded for a particular day
(see figure 23-8). Touching the HQ VDAY touch option/display border highlights the option and
enables calendar day data entry by touching the desired numbers on the keypad options (01 thru 31),
verifying the new calendar day data entry and then touching ENT. If there is a stored word of day for
the entered calendar day a tone sounds in the head set. The HQ VDAY option remains border
highlighted until HQ TIME, HQ WOD or HQ TNET is selected.
The HQ WOD option is used to manually enter the Have Quick word of day. Touching the HQ WOD
