EXHIBIT A
BASE STATION RADIO EQUIPMENT SPECIFICATIONS/REQUIREMENTS
RFB/EVENT #R2901-2000004167 (REBID)
1. Overview
A Daniels 60-110W W VHF P25 Base Station is being specified as listed on the Price Schedule, Exhibit
B, but responders can submit responses with substitute equipment that meet the
specification/requirement criteria detailed in Exhibit A, below and are deemed approved equal by the
State as detailed in the Special Terms and Conditions, Item No. 7.
The radio system shall consist of modular transmitters and receivers that employ an efficient low power
consumption design. The system shall be capable of continuous 100% duty cycle over a wide
temperature range. Interconnection between transmitter and receiver modules, as well as control and
monitor modules, will be through a main motherboard using printed circuit board techniques, with no
discreet wiring for all analog signaling. Digital interconnection will be accomplished via a front panel data
bus to allow for ease of upgrade and configuration changes. These modules must be interchangeable
with various standard motherboards that are capable of operation as standalone base stations, redundant
stations, repeater stations, receiver only stations, transmitter only stations. This requirement will reduce
the need for spare modules.
2. Modularity
The radio system shall comprise of a number of labeled plug-in modules so that interchanging for test and
repair is facilitated. The system shall be marked to show the location of all included modules. Modules
shall incorporate a device which secures them in position. Any unused module positions shall be
equipped with covers. Transmitter and receiver modules must be hot-swappable and capable of individual
field replacement. Transmitters will incorporate internal separate removable RF amplifier assemblies and
plug in synthesizer assemblies. Receivers will incorporate internal separate removable RF pre-amplifier
assemblies and plug in synthesizer assemblies.

Local test controls are to provide for local operation of the transmitter and receiver for test purposes.
Local test controls shall be provided on all equipment where local operation controls are not provided.
Provision for local test controls shall not preclude or degrade operation of the equipment by any primary
controls otherwise provided.
4. Speaker

receivers that have audio on the control lines. A speaker and speaker volume control shall be provided.
Audio output for local test shall not be less than 0.5 Watts.
5. Programming
Radio system must be field programmable. Channel selection shall be in 2.5 / 5.0 / 6.25 kHz increments
for VHF and 6.25 / 12.5 kHz increments for UHF. Channels must be programmed through software
changes. General operation of system will be selected through internal jumpers and control programming
software. All supplied radio systems must include the required programming interface hardware.
Programming software must have a built in update checker to allow user to check for new upgrade
availability on the internet (internet access required for this feature).
Additional features that must be programmed via the programming software include:


Adjustment of power and audio levels
Selection of status tone operation for receiver voting
NAC and TGID settings for P25 operation
6. Upgrade Capabilities
Radio system must be capable of receiving firmware upgrades in the field via the USB port on the front of
each radio module. Firmware updates must be available from the vendor’s website for download and
deployment. The radio system must be capable of being upgraded in the field from analog operation to
full P25 digital operation via a purchased firmware upgrade. P25 upgrade must require no additional
hardware to be added to the Transmitter or Receiver modules (not including encryption).
7. Continuous Duty over Temperature
Radio system must be capable of continuous duty (100%) over the entire temperature range of -30º to
60º Celsius. No reduction in duty cycle is acceptable.
8. Interoperability
Radio equipment must be compatible with current P25 standards to allow users from different agencies or
areas to communicate directly with each other. This will allow agencies on the federal, state or local level
(or any other agency) to communicate more effectively with each other when required. Analog, Digital or
Mixed mode shall capable on a channel by channel basis.
9. Modulation
In compliance with the P25 standard, radio equipment must not only provide a 12.5 kHz C4FM digital
channel, but must also be backwards compatible with existing analog 12.5 kHz channels and equipment.
10. Encryption
The P25 standard includes a requirement for protecting digital communications (voice and data) with
encryption capability. The encryption used in P25 is optional, allowing the user to select either clear (unencrypted) or secure (encrypted) digital communication methods. All Transmitter and Receiver modules
must have the capability to add encryption modules for secure communications when used in a base
station configuration. Encryption modules must be capable of AES or DES-OFB encryption methods.
Encryption modules must be field installable.
11. Over the Air Rekeying (OTAR)
The repeater must be capable of passing P25 OTAR signals without distortion.

12. Documentation
Radio system must include documentation that defines the configuration of the system as shipped.
Generic product information is not acceptable.
Configuration documentation must include:
 functional block diagram of system operation when applicable
 Jumper lists for controlling control hardware
 Detailed wiring diagrams for all included external devices
13. Maintenance
A. Test Points
Test points shall be provided for routine checks and alignment of the transmitter and receiver. These
test points shall be readily accessible and marked for ease of servicing. It shall be possible to make
measurements using conventional test instruments. If a card extender is necessary for in-service
tests and adjustments, one shall be included with each station.
B. Upgradeability
The radio system must allow for the upgrading of modules such as the Transmitter, Receiver and
control cards without requiring removal of the entire system. This will allow for both functional
upgrades as well as replacements in the event of failure.
C. Industry Standards
All proposed radio systems shall meet or exceed all appropriate and current Telecommunications
