P25 VHF Conventional and Trunking
The IC-F9511 series has P25 conventional and trunking capabilities as standard. You can assign individual channels to analog conventional, P25 conventional or P25 trunking, all within one radio.
Interoperability
The IC-F9511 series conforms to the standard specifications for TIA/EIA TSB-102, CAAB, Digital C4FM Transceiver Performance Recommendations and provides interoperability with other brand P25 equipment for public safety applications.
Digital/Analog Mixed Mode Operation
The mixed mode operation allows you to detect and receive both analog FM and P25 digital modes and to transmit either mode depending on programming.
Individual ID and Talkgroup ID
The IC-F9511 series has a 100 individual ID and 250 talkgroup ID memories. Use the display to visually select the person or group you’re going to call.
Optional AES/DES Encryption
The IC-F9511 series provides AES and/or DES encryption for secure conversation with the optional UT-125 AES/DES encryption unit or UT-128 DES encryption unit.
OTAR (Over-the-Air-Rekeying)
The IC-F9511 series supports P25 OTAR and trunked OTAR for changing encryption keys over the air.
Enhanced Vocoder Ready
With the optional remote control kit, RMK-2 and separation cable, the front panel controller of the radio can be detached from the main unit. It allows flexible installation in limited vehicle space. Separation cable length is selectable from 1.9m (6.2ft), 3m (9.8ft), 5m(16.4ft) and 8m (26.2ft).
Detachable Controller (Front Panel)
With the optional remote control kit, RMK-2 and separation cable, the front panel controller of the radio can be detached from the main unit. It allows flexible installation in limited vehicle space. Separation cable length is selectable from 1.9m (6.2ft), 3m (9.8ft), 5m(16.4ft) and 8m (26.2ft).
Dot Matrix, Multi-Function LCD
With a high contrast dot matrix display, upper and lower case characters can be easily distinguished. The display shows 12 characters by 2 lines. LCD backlight is standard.
IP54 Dust-Protection and Splash Resistance (Controller Only)
The rugged front controller panel is resistant to shock and vibration. When used with the optional separation kit, RMK-2, the controller head has dust-protection and splash resistance, equivalent to IP54.
Built-in CTCSS and DTCS Signaling
Use the built-in CTCSS and DTCS encoder and decoder capabilities* to set up your own talk groups, and have your radio stand-by quietly when other groups are talking. You can also set up selective calls to individuals or control a repeater.
* Analog mode only.
512 Memory Channels, 128 Zones
Up to 512 memory channels can be divided into 128 memory zones, allowing you flexible channel and communication group management.
Tactical Group Function
The tactical group function allows you to copy memory channels to the tactical zone and temporarily regroup memory channels. Using the optional zone copy cable, memory channels in the tactical zone can be transferred from a master radio to other radios.
Abundant Scanning Functions
The dual priority scan monitors two primary channels alternately, while scanning other channels. The mode dependent scan function automatically changes the scan list according to the operating channel setting. The talk back function with timer beep, TX channel and cancel channel settings allow you to preset the transmission channel when you push the PTT button during a scanning operation or cancel the scanning.
22W amp for Public Address (PA) and RX Speaker Functions
The IC-F9511 series has a built-in 22W BTL audio amplifier. When an external loud speaker is connected to the radio, you can speak through the radio’s microphone. The RX speaker function allows you to relay the received audio over the loud speaker.
Programmable Accessory Connector

The IC-F9511 series has a D-SUB 25-pin ACC connector for connecting external devices.
It has reserved pins for programming to input operating channels, turn on/off functions and output received audio or honk a horn, etc. In addition, an ignition sensing line allows you to control the radio power from the engine ignition switch.
Radio Stun/Kill and Power-on Password Function
The radio stun/kill function* disables a lost or stolen radio over the air, eliminating security threats from undesired listeners. The power-on password prevents unauthorized people from turning on the radio.
* P25 digital mode only.
Optional Active Noise Canceling Microphone
The optional active noise canceling microphone HM-211 can automatically reduce noise in extremely noisy environments and assist in transmitting clear and accurate audio.

Ingress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.


Degrees of Solid Particle Protection – 1st Digit
IP6x | No ingress of dust; complete protection against contact. (Dust tight) |
---|---|
IP5x | Protected from the amount of dust that would interfere with normal operation. (Dust protected) |
Degrees of Liquid Ingress Protection – 2nd Digit
IPx8 | Protected against continuous immersion in water. Depth and duration specified by model. |
---|---|
IPx7 | Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes |
IPx6 | Protected against water projected by powerful jets from any direction. 100 L per minute by a powerful jets (12.5 mm) for 3 minutes. |
IPx5 | Protected against water projected by jets from any direction. 12.5 L per minute by a nozzle (6.3 mm) for 3 minutes. |
IPx4 | Protected against water splashed against the equipment from any direction |
