WARNING
Contact with the antenna or exposure directly in front of the antenna during
DAMA SATCOM transmissions may cause injury to personnel. In DAMA
SATCOM operation, the AN/PRC-117F interacts automatically with the channel
controller, transmitting and receiving as needed. This automatic transmission
may not be apparent to the operator; therefore, all personnel should avoid
contact with the antenna or exposure directly in front of the antenna.
i.
The 25-kHz DAMA UHF SATCOM is operated in either AC or DC. The
AN/PRC-117F uses the following types of DAMA presets to manage operating
parameters. These presets allow for quick configuration changes to any type of
operation.
(1) DAMA net presets, 10 each—0 to 9.
(2) DAMA port configuration presets, 10 each—0 to 9.
(3) DAMA destination presets, 50 each—00 to 49.
j.
Verify that the SATCOM antenna is oriented correctly using a magnetic compass
to point it on the proper azimuth, as determined from pointing slide rule graphs or
software applications. Make an approximate adjustment in the elevation angle as
needed. SATCOM RSSI test cannot be used in DAMA operation.
k. Initial operation calls may be either normal DAMA circuit service calls or DASA
dedicated calls. See Table C-9. Perform the following procedure for initial operation:
(1) Rotate function switch to CT.
(2) At the OPERATIONAL MODE prompt, select DAMA; press ENT.
(3) Select the desired DAMA net preset by pressing the left/right arrow keys on
the KDU to scroll to the NET preset number and use the KDU numeral keys to enter
the desired net preset number.
Note: In DAMA mode, the PRE + / - key on the KDU is disabled to prevent
inadvertently changing the net preset while in a net connected state.
C-18
(4) Press the circular change key to see that the proper DAMA port configuration
preset is selected for the intended DAMA service request. If a different DAMA port
configuration preset is desired, use the left/right arrow keys on the KDU to scroll to the
preset number. Enter the required preset number and press ENT.
(5) Begin radio operation. View main screen for network status changes in the
order listed:
(a) ACQUIRING.
(b) RANGING (active ranging method only).
(c) LOGGING IN (5-kHz only).
(d) CONNECTED.
(6) Network status of CONNECTED indicates the terminal is ready to request or
receive services in the DAMA network. If terminal does not become connected, check
antenna pointing, loading, and programming assignment of the proper EOW TSK and
TBA. ERROR network status indicates that no DAMA EOW TSK is loaded.
l.
The 25-kHz DAMA has two modes of operation: AC or DC. The channel
controller determines the frame format of the channel and the radio operates
accordingly.
m. Calls in 25-kHz AC DAMA may be made from one to five terminal or network
addresses. A network address is a predetermined group of terminals operated together
as a network. Determine the following before making a call request:
(1) Type of Service. Before placing the call, use the proper DAMA port
configuration preset for the service needed from the service state display screen. On
changing the port configuration preset with a connected terminal, the radio sends a
status report B RCCOW to the channel controller for notification of the new
configuration. For DASA dedicated calls in 25-kHz AC DAMA, a port configuration
preset with a configuration code to signify DASA must be used. Refer to current
configuration codes.
(2) Station(s) to be Called. DAMA destination presets are used in call menus to
select station(s) to be called. TBAs associated with this destination preset are shown on
the line below the DAMA destination preset name.
(3) Precedence of the Call. Use the proper precedence for the importance of the
required service. If a higher precedence than authorized is used, the call is denied. Not
all terminals have access to every precedence level. Check with organization DAMA
planners and authorization documents. At certain times, the channel controller can
place precedence restrictions. The AN/PRC-117F does not allow calls below this
precedence during these times.
(4) Duration of the Call. Request enough time to complete the required
communications; service is terminated automatically at the end of this time. See Figure
C-9. Perform the following procedure to place a call using 25-kHz AC DAMA:
(a) Press CALL key to bring up SELECT REQUEST TYPE.
(b) Select PLACE A CALL and press ENT.
C-19
(c) Select the destination to be called. Use the left/right arrow keys to select
the DAMA destination preset number field, then enter the preset number needed. As
an alternative, select the destination name field or scroll through the DAMA destination
presets names with the up/down arrow keys. Press ENT when proper destination
preset number or name is in view. The TBAs associated with this destination preset are
shown at the bottom of the display.
(d) At the next display screen, choose the precedence of the CALL and press
ENT.
Note: When the channel controller places system restrictions, it sets the
minimum precedence required to place a call on the DAMA channel.
When this happens, the call precedence not authorized is no longer
showm on AN/PRC-117F call menus.
(e) Enter the required call duration in number of seconds, minutes, hours or
days (or input 0000 for indefinite). Use the left/right arrow keys to select between
either the unit digits field or the units. Press ENT when correct time and units are
selected.
(f) The display returns to the main operational display. Service state
changes to PENDING. Wait for the radio to send the request to the channel controller.
(g) Observe the following service states:
• PENDING—Radio terminal is negotiating the sending of the call
request and action on it from the channel controller. Wait until it becomes active or a
system message is received concerning the request.
• ACTIVE—Service request has been granted, the normal indication to
commence operation with the requested service.
• QUEUED—Service request is being held and is granted when channel
resources are free. Wait until the service is granted or terminate the call and try again
later.
• DEDICATED—Indicates that DASA operation has been granted.
Operation in DASA is ruled by MIL-STD 188-181A covering 5-kHz and 25-kHz
dedicated UHF SATCOM.
• IDLE—The radio is not active or is setting up a service.
n. Terminate a 25-kHz AC DAMA call on completion. The user should terminate
the timed or indefinite call so the channel controller can reassign that channel to
another terminal user in the network.
o. The 25-kHz DAMA has two modes of operation: AC or DC. The channel
controller determines the frame format of the channel and the radio operates
accordingly.
p. Calls in 25-kHz AC DAMA can be made from one to five terminal or network
addresses. A network address is a predetermined group of terminals operated together
as a network. Determine the following before making a call request:
C-20
(1) Type of Service. Before placing the call, use the proper DAMA port
configuration preset (from the service state display screen) for the service needed. On
changing the port configuration preset with a connected terminal, the radio sends a
status report B RCCOW to the notify channel controller of the new configuration. For
DASA dedicated calls in 25-kHz AC DAMA, use a port configuration preset with a
configuration code to signify DASA. Refer to current configuration codes.
(2) Station(s) to be Called. DAMA destination presets are used in call menus to
select station(s) to be called. TBAs associated with this destination preset are shown on
the line below the DAMA destination preset name.
(3) Precedence of the Call. Use the proper precedence for the importance of the
required service. If a higher precedence than authorized is used, the call is denied. Not
all terminals have access to every precedence level. Check with organization DAMA
planners and authorization documents. At certain times, the channel controller can
place precedence restrictions. The AN/PRC-117F does not allow calls below this
precedence during restricted times.
(4) Duration of the Call. Request enough time to complete the required
communications; service is terminated automatically at the end of this time. See Figure
C-9. Perform the following procedure to place a call using 25-kHz AC DAMA:
(a) Press CALL key to bring up SELECT REQUEST TYPE.
(b) Select PLACE A CALL and press ENT.
(c) Select the destination to be called. Use the left/right arrow keys to
select the DAMA destination preset number field, then enter the preset number needed.
As an alternative, select the destination name field or scroll through the DAMA
destination presets names with the up/down arrow keys. Press ENT when proper
destination preset number or name is in view. The TBAs associated with this
destination preset are shown at the bottom of the display.
(d) At the next display screen, choose the precedence of the call and press
ENT.
Note: When the channel controller places system restrictions, it sets the
minimum precedence required to place a call on the DAMA channel. The
call precedence not authorized is no longer shown on AN/PRC-117F call
menus.
(e) Enter the required call duration in number of seconds, minutes, hours,
or days (or input 0000 for indefinite). Use the left/right arrow keys to select either the
unit digits field or the units field. Press ENT when correct time and units are selected.
(f) The display returns to the main operational display. Service state
changes to PENDING. Wait for the radio to send the request to the channel controller.

C-23
q. Terminate 25-kHz AC DAMA calls on completion. The user should terminate a
timed or indefinite call so the channel controller can reassign that channel to another
terminal in the network. Perform the following procedures to terminate a call:
(1) From a service state display indicating ACTIVE and time remaining, press
CALL.
(2) From SELECT REQUEST TYPE display, select TERMINATE CALL with the
up/down arrow keys; press ENT.
(3) The TERMINATE CALL request is sent to the channel controller. The
channel controller tearsdown the service and the service state of the terminal returns to
one of the service states (IDLE, PENDING, or QUEUED), depending on other ongoing
requests.
r. Send a 25-kHz AC DAMA out-of-service request to the channel controller instead
of logging out as in 5-kHz DAMA. In these requests, the duration for being out of
service, precedence, and reason code is transmitted. If another station attempts to call
the terminal during the out-of-service period, the channel controller can report the
reason code and time to be out of service to that user. Perform the following procedures
to send an out-of-service request:
(1) Press CALL key to bring up SELECT REQUEST TYPE display.
(2) Select OUT OF SERVICE and press ENT.
(3) Select precedence for out-of-service request and press ENT.
(4) Enter two-digit numerical out-of-service code.
(5) Enter duration for the out of service period; use 0000 if it is to be indefinite.
Press ENT.
(6) The out-of-service request is sent to the channel controller. Watch the
display for acknowledgement from the channel controller.
s. To return to service in 25-kHz AC DAMA operation, send a status report B
RCCOW (menu item RETURN TO SERVICE) to the channel controller. This informs
the channel controller that the operator has returned. When an operational radio is
unmanned, it is not necessary to use this menu item when turning on after a power off.
The RCCOW sent to the channel controller when connected notifies the channel
controller of return to service. Perform the following procedure to return to service:
(1) Press CALL key to bring up SELECT REQUEST TYPE display.
(2) Select RETURN TO SERVICE and press ENT.
(3) A Status report B RCCOW is sent to the channel controller.
t. In 25-kHz UHF AC DAMA, an AN/PRC-117F terminal user can page up to three
other terminals. Paging is available only in 25-kHz AC DAMA. Using organization
network planners, determine the procedures on responding to pages. See Figure C-10.
Perform the following procedure to page:
(1) Press CALL key to bring up service request screen of SELECT REQUEST
TYPE.
(2) Select PAGE and press ENT.
C-24
(3) Use KDU number keys to type in the first address to page; press ENT to
accept number.
(4) Repeat step 3above for the second and third addresses. (If no more addresses
need to be paged, type 0000 and press ENT.)
(5) The radio sends the page request to the channel controller. The paged
station should respond as unit procedure dictates.
Figure C-10. Twenty-five-kHz AC Paging and Link Test
u. To alleviate problems in 25-kHz AC DAMA operation, the channel controller can
send an information request code to request information (INFO Report, see Figure C-
10). from the terminal operator. The terminal operator must respond to the request
with an information report code to continue operation in DAMA. Perform the following
procedure to send an information report code at any other time:
(1) Press CALL to bring up SELECT REQUEST TYPE display.
(2) Select INFO REPORT from menu and press ENT.
(3) Enter the desired information report response code to send to the channel
controller and press ENT. The radio sends the code to the channel controller.
v. The 25-kHz DAMA has start-link test built into its frame format. Link testing
determines suitability for data operations using more robust frame formats that support
higher burst data rates. It does not reduce channel overhead allotted to supporting
C-25
communications. Slower data rate link tests require more time to complete. Refer to
Table C-13. Perform the following procedure to conduct a link test:
(1) Press CALL key to bring up SELECT REQUEST TYPE display.
(2) Select START LINK TEST and press ENT.
Note: This sends a link test request to the channel controller. When the link
test slot becomes available, the channel controller commands the radio to
begin the link test. On completion of the link test, the radio displays the
results in number of bit errors and missed acquisitions during the test.
Results are recorded automatically by the channel controller and used to
determine data burst rates. Terminals that show good results in link
tests are assigned frame formats supporting more robust burst data rates,
thereby increasing overall data throughput.

w. Abort link test (25-kHz AC or DC DAMA ) and use the radio for another purpose,
perform the following procedure:
(1) Press the CALL key to bring up the SELECT REQUEST TYPE display.
(2) Select ABORT LINK TEST and press ENT. The radio aborts the link test
process and terminates the link test.
x. View network status messages (all DAMA modes). The AN/PRC-117F displays
operational status messages that pop up on the display and are then placed into a
message database while DAMA operation continues. To determine the steps in an
operation while using DAMA, refer to the technical manual for a list of the messages
and their explanation. There are two methods that may be used to view messages while
operating in UHF DAMA SATCOM: message indicator method and options menu
method.
y. Perform the following procedure for the message indicator method:
(1) Press the left/right keys to scroll over to the envelope icon on the operational
display and press ENT.
(2) Use the up/down arrow keys to scroll through the message database.
(3) Press CLR to return to operational screens.
Note: When operations on a current DAMA net terminate, all the DAMA status
messages erase. Some pop-up messages require operator intervention to
continue.
C-26
z. In 5-kHz DAMA, calls can be made to a single terminal address for a point-to-
point capability or to a sub-net address giving network capability. The nine-second
frame format creates long delays for voice users. The 5-kHz DAMA network operation
was designed and, therefore, more suited for DATA operations. DASA dedicated service
requests are used to handle service requests greater than the DAMA channel can
handle. On entry into DAMA mode using a properly configured DAMA net preset, the
AN/PRC-117F automatically acquires, ranges, and logs in with the channel controller.
Network status shows CONNECTED, if successful. DASA call requests are placed with
precedence of the call and the desired duration. Service request can be granted, placed
in queue, or denied. Calls made with a precedence higher than authorized are denied.
The 5-kHz DAMA has two basic modes of operation of circuit or message service. The
AN/PRC-117F is placed in each mode by changing it on the display. The mode of
operation is selected prior to operation in that mode. If a service message is received
while in circuit mode, the radio is switched to message mode to download the message.
(1) Circuit service provides half-duplex encrypted voice or data service to a single
destination or to a network, or terminals grouped under a sub-network address.
(2) Message service is a specialized data mode that provides packet transmission
and reception of data messages up to 14 kilobytes. This requires an external data device
to input the message to the AN/PRC-117F.
aa. Place a call (5-kHz circuit service or dedicated call). (See Figure C-11.) Requests
for circuit service and dedicated calls are essentially the same. Dedicated service gives
a channel unhindered by the delay the long 5-kHz DAMA frame format. Not all users
have authorized use of dedicated service. Dedicated service is used to support data
rates and message lengths not adequately supported by circuit service. Consider the
following items before placing a call:
(1) Type of service. Use the proper DAMA port configuration preset for the
service needed. Select this preset from the service state display screen before placing
the call.
(2) Station(s) to be called. DAMA destination presets are used in call menus to
select station(s) to be called. TBAs associated with this destination preset are displayed
on the line below the DAMA destination preset name.
(3) Precedence of the call. Use the proper precedence for the importance of the
required service. If a higher precedence than authorized is used, the call is denied. Not
all terminals have access to every precedence level. Check with organization DAMA
planners and authorization documents.
(4) Duration of the call (DASA only). Request enough time to complete the
required communications. Service is terminated automatically at the end of this time.
Additionally, when making DASA calls, select either 5-kHz NB or 25-kHz WB channels.
Perform the following procedure to place a call using 5-kHz DAMA:
(a) Rotate function switch to CT.
(b) After the radio initializes, press MODE.
(c) At the OPERATIONAL MODE prompt, select DAMA; press ENT.

show on the bottom line of the display.
(k) At next display screen, choose the precedence of the call and press ENT.
(l) At DASA REQUEST? prompt, select YES for dedicated service and NO
for regular DAMA circuit service.
(m) Enter the required DASA call duration in numerical units of seconds,
minutes, hours, or days (or use 0000 for indefinite). Press ENT when proper time and
units are selected. Time is not entered for normal DAMA calls.
(n) For DASA dedicated calls, channel type (5-kHz or 25-kHz) is also
requested in the call request. This menu option is not shown when making a normal
DAMA circuit service call.
(o) The display returns to the main operational display. Service state
changes to PENDING. Wait for the radio to send the request to the channel controller.
(p) Observe the service state display for the following indications:
• PENDING—Radio terminal is negotiating the sending of the call
request and action on it from the channel controller. Wait until it becomes active or a
system message appears concerning the request.
• ACTIVE—Service request is granted. This is the normal indication to
commence operation with the requested service.
C-28
• PREEMPTED—An active service is preempted by a higher priority
service. Wait for the service to become active again.
• DEDICATED—Indicates that DASA operation is granted. Operation in
DASA is ruled by MIL-STD 188-181B covering 5-kHz and 25-kHz dedicated UHF
SATCOM. Use the appropriate DAMA port configuration preset needed for the DASA
service.
• IDLE—The radio is inactive or setting up a service.

should be terminated. Perform the following procedure to terminate a dedicated call:
(1) At the end of using DASA dedicated service, press CALL button on KDU.
(2) Use up/down arrow keys to scroll to TERMINATE CALL.
(3) Press ENT to terminate call.
(4) Service state goes to IDLE after reacquiring the network home channel.
dd. Send a message using 5-kHz DAMA message service. DATA messages of less
than 14 kilobytes are uploaded to radio and the packet is sent to the destination
address. The terminal prompts a message upload to the radio. Perform the following
procedure to send a message:
(1) Ensure the DATA device is connected to the J1 ADF connector or J3 data
connector and is ready for operation with a message to be transmitted.
(2) Select a DAMA port configuration preset that properly interfaces the data
device to the radio using KG-84C encryption.
(3) Press the circular arrow keys to move display screens to service state screen
to place radio in MSG mode. If radio is in CKT mode, use the left/right arrow keys to
scroll to MODE and change to MSG mode with the up/down arrow keys, then press
ENT.
(4) Press CALL key to bring up display for SELECT REQUEST TYPE. See
Figure C-12.
(5) Select SEND A MESSAGE and press ENT.
(6) Select DAMA destination preset to which the message is sent and press ENT.
TBAs associated with this preset are shown across the bottom line of the display.
(7) The next display is SELECT PRECEDENCE. The display shows the
precedence last used to call the selected destination. Press ENT to keep that precedence,
or scroll and select an alternate message precedence.
(8) After a brief configuring screen, the terminal prompts the user to ENTER
MESSAGE to the radio. Send the message on the data device to upload it into the
radio. Press CLR to abort.
(9) When uploading is complete, the service state indicates IDLE with a message
status of one (1) for outgoing. After the message is transmitted, the outgoing message
indicator number decreases.
C-30
ee. Receive a data message using 5-kHz DAMA message service. Depending on
operation of the particular data device, the radio is programmed to either automatically
download a received message from the radio buffer to the data device, or manually
download a received message after the data device is ready to accept it from the radio.
When using manual message release, remember to download messages so additional
messages are received without losing important data. When using 5-kHz message
service, the AN/PRC-117F is operated with a network state of CONNECTED and a
service state of IDLE. When a sender initiates sending a data message to the terminal,
the channel controller looks for the presence of the destination terminal and sets up a
service between the two terminals. On successful transmission, the AN/PRC-117F
indicates (in its message buffer) that it is holding a message for downloading. If the 5-
kHz MSG mode is set to AUTO instead of MANUAL, it sends the message immediately
to the interfaced output data device. Perform the following procedure to download a
message using 5-kHz message service with manual message mode:
(1) Verify there is a buffered message in the radio and the radio is in MSG mode.
(2) Connect the data device to either the J1 ADF connector or J3 data port, as
applicable, and ensure it (connector or port) is ready to receive the message.
(3) Press the CALL key and bring up SELECT REQUEST TYPE display.
(4) Select DOWNLOAD MESSAGE and press ENT.
(5) The service state changes to DOWNLOAD and the message is sent to the
data device. When complete, the service state changes back to IDLE.
(6) Check the data device for proper reception of the message. The incoming
message number is decremented.
C-31

ff. Log out of 5-kHz DAMA. To leave the 5-kHz DAMA channel, the terminal must
log out with the channel controller. Also, this is required if shutting the radio off for
any reason (such as changing the batteries or adjusting the antenna). Perform the
following procedure to log out of a 5-kHz DAMA net:
Note: If the radio goes off the net without logging out, the channel controller
automatically logs it out after it missed 200 ROWs (approximately 30
minutes). Until it logs out, the channel controller considers the terminal
logged in. If the terminal attempts to log in a second time, the channel
controller may reject the second log in attempt. If a log in is rejected, go
into net preset programming (Figure C-6) and change log in type to
preassigned. The terminal is connected again. Return setting to over-
the-air after the net connects again.
(1) Press the CALL key to bring up the SELECT REQUEST TYPE display
screen.

(2) Use the up/down arrow keys to select LOG OUT; press ENT to log out.
Note: The service state and network state switch to DISABLED after the
channel controller acknowledges the log out request. The radio is
switched to another DAMA net preset, or turned off. Figure C-13, Figure
C-14, and Figure C-15 provide screen displays and descriptions for the
radio.

b. To ensure the terminal receives communications from a terminal, place that
network address (common guard, private guard, or subnet) in the guard list (do not enter
the terminal address). To add to (or change) the guard list, follow the procedure below.
Note: The guard list is a set of addresses for which a terminal receives services.
The guard number is the address of a single terminal or network. Terminal
addresses from which communications need to be received by a specific
terminal are placed in the guard list. When a terminal address is placed in
the guard list, the control station logs that address into the network.
The guard list procedure is not recommended for 5-kHz DAMA. If a guard
list is used for a 5-kHz terminal, ensure the terminal addresses placed in the
guard list are not used by another active terminal.
The demarcation point divides addresses between single terminals and
networks. Addresses below the demarcation point (single terminals) should
usually be left off the guard list.
(1) Press ESC until the main menu is displayed.
(2) Press 2 (database options).
(3) Press 2 (guard list).
