RF Radiation Hazard
Transmitting Automatically
AN/PRC-117F Safety Warnings
RF Radiation Hazard: Avoid contact and prolonged close proximity exposure to
transmitting antennas.
UHF DAMA SATCOM and High Performance Waveform (HPW) SATCOM and
Line-of-Site (LOS) data operation causes the radio set to transmit automatically
without operator intervention. ARQ Data System Reception also causes the
radio to transmit its acknowledgments. Avoid contact with all antennas or
exposure directly in front of the SATCOM antenna.

Battery Safety Warnings
Do not charge, short circuit, incinerate, or mutilate the BA-5590/U Lithium
Battery.
• If the battery becomes hot, a hissing sound is heard, or venting occurs, move
personnel and equipment to a well ventilated area.
• Do not dispose of lithium batteries in uncontrolled trash.
– Local regulations will apply.
• The radio will operate using mixed battery types by auto regulating voltage.
– When operating the radio with mixed battery types, ensure that only
rechargeable batteries are put on a re-charging unit.

Cautions
• Unauthorized frequencies
• Antenna and connector damage
• Controlled Cryptographic Item (CCI)
Do not operate the AN/PRC-117F on unauthorized frequencies. The AN/PRC-
117F frequency band coverage does not constitute authorization for
indiscriminate use of any frequency.
• Turning the Antenna Adapter Body or VHF Blade Antenna can damage the
Radio Frequency Antenna connector on the radio and damage the antenna itself.
• The AN/PRC-117F radio is a Controlled Cryptographic Item (CCI). Use
appropriate security measures to protect it as dictated by your security manager
or service regulations.
– Double barrier locked storage devices for un-keyed storage
– Store radio with function switch set to CLR
– Filled radio takes on same classification as loaded keys

AN/PRC-117F Features (1)
LOS fixed frequency operation from 30 MHz to 511.99999 MHz
• Dedicated UHF SATCOM using 5 kHz Narrowband (NB) or 25 kHz Wideband
(WB) Channels
- Digital squelch
- Auto selecting Mixed Excitation Linear Prediction (MELP) or Linear
Predictive Coding (LPC-10) digitized voice.
• DAMA UHF SATCOM 25 kHz or 5 kHz
• Single Channel Ground and Airborne Radio System (SINCGARS)
- ASIP and ESIP compatible
• HAVEQUICK I & II Compatibility

• High Performance Waveform (HPW) option
• Embedded US Type-1 COMSEC:
• VINSON (KY-57/58)
• Advanced Narrow Band Digital Voice
Terminal (ANDVT)
•KYV5
• Fascinator
•KG-84C
• Replaceable Hold-Up battery (HUB)
AN/PRC-117F Features (2)
High Performance Waveform can pass data up to 64 kbps
• Embedded COMSEC:
- VINSON COMSEC is based on the SAVILLE encryption algorithm and 16
kbps CVSD audio compression. Data can also be passed up to 16 kbps.
- Advanced Narrow Band Digital Voice Terminal (ANDVT) uses LPC-10 or
MELP voice encoding at 2.4 kbps
- KYV5 (SINCGARS ESIP) uses VINSON COMSEC keys and allows
Enhanced Data Mode data rates
- Fascinator encryption is similar to VINSON but at 12 kbps, uses VINSON
COMSEC keys.
- KG-84C is primarily data encryption. However, it can be used for voice on
dedicated SATCOM channels, 2.4 kbps for voice, up to 64 kbps for data.
The replaceable Hold-Up battery retains programming and COMSEC when the
function switch is in the off position.
10
• 100 programmable net presets
• 10 DAMA net presets
• Program presets via computer
• Radio Firmware is upgradable
• Civilian PT LOS System Interoperability
–CDCSS
–CTCSS
– Narrowband AM Support
AN/PRC-117F Features (3)
• The 100 programmable net presets are for the following: LOS, SATCOM, or
HOPPING (SINCGARS or HAVEQUICK)
• The 10 programmable DAMA net presets are separate from the other 100
presets.
• Harris offers a Radio Program Application that allows the operator to program
the radio via computer. The program is free but requires a 9-pin serial to 27-
pin cable. The cable connects to J3 or J6 front panel.
• The radio Firmware is upgradeable to allow for new features and
improvements without changing hardware.
• Civilian Plain Text LOS System Interoperability
- CDCSS (Continuous Digital Controlled Squelch System) with 83 EIA codes
- CTCSS (Continuous Tone Controlled Squelch System) with 41 EIA tones
- NB AM Support with 8.33 KHz and 12.5 KHz channel spacing in addition to
normal 25 KHz spacing.

Other Capabilities (1)
• BIT(Built-in-Test)
• Scan Mode
• Remotely Controlled
• OTAR/OTAT capable
• Emergency Beacon Mode
• The Built-in-Test allows the operator to self-test the radio; check the firmware
& hardware versions; check the battery voltages & type; check how long the
radio has been in operation with the Elapsed Time Indicator (ETI); and check
the radio’s serial number.
• In scan mode, the radio can scan between 2 and 10 LOS voice and SATCOM
voice nets in either Cipher Text or Plain Text. The radio cannot scan Hopping
or DAMA nets.
• The radio can be controlled remotely from a PC on J3, J6, or J9 ports. These
ports must be configured for remote control first.
• It is capable of Over-the-Air- Rekeying (OTAR) and Over-the-Air-Transfer
(OTAT). This is where a distant radio can be rekeyed or a key can be
transferred to a fill device attached to the distant radio.
• It is capable of transmitting a user programmed emergency locator beacon.
12
• Retransmit capable
• Clone Mode
• Automatic whisper microphone
• Custom SATCOM Frequency Code Table
• External GPS Interface
Other Capabilities (2)
• Capable of Retransmission to extend its range. Can retransmit across
modulations & net types
• Can Clone its programming to another radio. Only the programming data can
be cloned; NSA does not allow transfer of COMSEC and Hopping data
between radios
• Automatically boosts low audio input signals
• There is a Custom SATCOM Frequency Code Table built into the radio. The
codes will configure the radios’ frequencies, bandwidth, modulation mode and
other important configurations.
• The external GPS interface can be used with the AN/PSN-11 PLGR, Rockwell
Collins PLGR-II, DAGR, and civilian NMEA compliant GPS receivers.
- Position and navigational data can be displayed on the radio
- Can be used for Situational Awareness
