RCVRg
BANDg  Access Band screen for this radio.
SQUELCHs  Toggles squelch ON or OFF.
RTNg  Returns to previous screen without changing settings.
3.7.2.4 HVQK Setup Screen. The HVQK Setup screen allows control of frequency hopping modes.
SOFT KEY  FUNCTION
gHVQK -Title of screen.
SETUP

Fill Status Line  Gives .ll status of IN-PROG WOD load in progress. COMPLT WOD load complete. INVALID No WOD in memory.
gEMERG Starts radio with internal clock, and START sets the radio to HVQK I mode.
gGPS-TOD  Synchronizes internal clock with
SYNC  GPS, and sets the radio to HVQK I mode.
gRCV -TOD  Commands radio to receive external TOD.
gSND -TOD  Commands radio to transmit TOD.
SOFT KEY  FUNCTION
VERIFYg  Initiates a MWOD verify for the day information entered. If a valid MWOD is in the radio, the radio will respond with an audio tone.
LOAD WODSg  Starts a WODS load from CDU data base mission memory to the radio. When loading is complete, erases MWOD data from data base mission memory, and sounds a con.rming tone in the headset.
3.7.3 HAVE QUICK (HQ) System.
a. The HQ system provides a jam resistant capability through a frequency hopping technique. Frequency hopping is a technique in which the frequency being used for a given channel is automatically changed at some rate com-mon to the transmitter and receiver. This is referred to as the normal mode, while frequency hopping operation is called the anti-jam (AJ) mode. Several ingredients are nec-essary for successful system operations. These are:
(1)
Common frequency.

(2)
Time synchronization.

(3)
Common hopping pattern and rate.

(4)
Common net number.

b.
The common frequencies have been programmed into all HQ radios. Time synchronization is provided via UHF radio and/or hardware by external time distribution system. A time-of-day (TOD) signal must be received from the time distribution system for each time the system is powered up. GPS may be used for TOD, but needs to be updated upon power up, after the GPS initializes itself. The hopping pat-tern and hopping rate are determined by the operator in-serted word-of-day (WOD). The WOD is a multi-digit code, common worldwide to all HAVE QUICK users. In the AJ mode, a communications channel is de.ned by a net number instead of a signal frequency as in the normal mode. Before operating in the AJ mode, the radio must be primed. This consists of setting the WOD, TOD, and net number. The anti jamming mode is a function of the band setting.

3.7.3.1 Time Of Day (TOD) Transmission. The TOD entry is normally entered before .ight, but it is possible to enter it in .ight. Use the HVQK -SETUP screen to re-ceive and transmit TOD information.
3.7.4 Modes of Operation. The radio set can be used for these modes of operations:
3.7.4.1 UHF AM Clear Voice. UHF AM uncoded voice transmission and reception.
3.7.4.2 UHF AM Secure Voice. UHF AM encrypted voice transmission and reception through the attached KY-
58.
3.7.4.3 HAVEQUICK anti jamming frequency hop-ping. Frequency hopping may be done in three submodes, HAVEQUICK I, HAVEQUICK II, and non NATO HAVEQUICK.
3.7.5 Normal Operation.
3.7.5.1 UHF AM Mode.
NOTE
Initial battery power on and/or initial APU ac power on may cause Com 2 AN/ARC-164togo to CT mode -Via CDU Com 2 soft key, select PT mode.
1.  
COM .xed function key -Press, to access COM SUM screen.

2.
SK 2 soft key -Press, to edit frequency or pre-set.

NOTE
If the radio is already in the desired band, and its preset and/or frequency desired is known, it may be edited on the COM SUM screen, and steps 4 thru 7 will be unneces-sary. To edit preset or frequency, ensure that preset or frequency has edit box around it. Enter new number in scratchpad, then ENT -Press.
