PC programmable UHF trunked radio.
Many of today's Community Repeater and
Specialized Mobile Radio (SMR) operators are considering the emerging
business opportunities in UHF trunking. Also, the new Enhanced
Specialized Mobile Radio (ESMR) network solutions are and effective
strategy for the traditional dispatch market now being attacked by PCS
and Cellular phone competition. The Icom IC-F4TR is the perfect
subscriber unit for this strong and viable market. Conventional
operation, basic LTR® and PassPort® are all built-in offering you a
complete upgrade path as your system grows. Flash memory will enable the
easy addition of future system enhancements as they are developed. Icom
radios are known for their rugged MIL spec, reliability and solid
performance, and so is the
IC-F4TR, a strict requirement for a problem-free fleet radio. 
Multiple modes
Conventional, basic LTR® and PassPort® are built-in. Conventional
operation and talk-around are both available from the front panel during
LTR® and PassPort® operation. Flash memory enables future system
upgrades and future compatibility with other protocols.
Conventional features
250 channels either 12.5 kHz or 25kHz, CTCSS, DTCS and alpha names.
LTR® features
50 systems with up to 100 groups per system. All basic LTR® system
features.
PassPort® features
60,000 useable ID's, individual mobile ID's and roamer ID's wide area
dispatch, selective calling, ESN (Electrical Serial Number) check,
message trunking, OTAR (Over the Air Re-programming), automatic
registration, call forwarding and voice mail.
Advanced trunking
performance
Our new Fractional-N system for ultra high-speed PLL lock-up provides
faster acquisition times and efficient trunking performance. The
built-in receive signal strength indicator (RSSI) enables seamless
roaming under the PassPort protocol, as the IC-D4TR automatically
registers with the nearest site (does not rely on BER calculations
which slow down the registration process).
Simple and keypad
versions
Select which is right for you, the keypad version with full interconnect
capability or the simple dispatch subscriber unit without keypad.
Entire UHF bandwidth
usable
Three bandwidth versions (400-430 mHz, 450-490 MHz, and 480-512 MHz) all
have switch able 12.5/25 kHz width by channel, and 5/6.25 kHz frequency
pitch making all the new UHF channels available for trunking, even if
your channels aren't right next to each other.
Alphanumeric display
The 8 digit LCD display has 18 icons that indicate system status and
operational selections, including battery condition. The new 11 segment
character set may be toggled from the control panel between system/group
numbers or PC pre-programmed alpha names.
Programmable keys
Each version ha 7 PC programmable keys, which may be assigned functions
to customize operations for end user, System Group, Home System,
Scan/Scan clear, Talk around, Auto dialer, and keypad lock are some
assignment examples.
Advanced PC programming
You may assign mode (conventional, LTR® or PassPort®
) by system, default talk group for home button, power-on home or
previous group, over the air programming for PassPort® network
roaming, 5/3 MHz offset by channel and area bit by system, Tx and Rx ID,
and UID for PassPort® .
MIL grade durability
Durable design features a one-piece aluminum die-cast chassis,
polycarbonate front panel and screw type antenna. The IC-F4TR meets MIL
spec, C, D and E.
Multiple scan mode
Conventional, system and group scan enable continuous contact under
multi-system operation without any action by the end-user.
Other features
- Powerful 4 W output with the
standard battery.
- 1050 mAh Ni-Cd battery pack.
- CTCSS, DTCS and DTMF encoder/decoder
built-in.
- Scanning, Time out timer functions
available.
- IBM/PC Widows programming
capabilities.
- DTMF encoder/decoder, selective
call, ANI and stun/kill.
- CTCSS, DTCS encoder/decoder and
reverse burst.
