KMX-T VHF/UHF trunked mobile radios The KMX-T trunked mobile radio series packs an amazing array of features into its ultra compact casing. Available in frequency bands ranging from 66 MHz to 960 MHz, it is designed for use in advanced trunking systems (MPT 1327) which may make use of both speech and data modes. This means they are the ideal choice for applications where functions such as vehicle location and monitoring are essential. KMX-T radios have been designed to be simple and user friendly, with familiar tones, straightforward controls and a clear 3-digit LED display with indicators for TX, Stack, Status and Service. The display shows the incoming call identity, call timer and status received, and if the user is away from the radio it will store details of up to 20 calls received in absence. Special selector buttons on the speaker/microphone ensure fast dialling. There are up to 999 selectable addresses and up to 99 pre-set addresses including a wide range of call types: normal, group, broadcast, priority, emergency, divert, cancel divert, status, 4 and 9 digit PABX, 20 digit PSTN and open channel non-trunked. An integral 1200 baud modem allows full data capability including SDMI, SDM2 and NPD. Enhanced data protocols enable fast, efficient and reliable data messages of up to 2048 bytes per transaction, or repeated transactions up to the maximum call time. Features Compact - complete with speaker/microphone RF power output up to 25W, programmable Choice of MPT 1343 or other numbering systems Programmable 'call request' mode routes calls to unanswered call stack Mobile status interrogation RS232 program/data serial port operating at 4800 baud RS232 chassis mounted connector Full control of radio operation via RS232 port for enhanced dispatcher operation including temporary or permanent dynamic regrouping and full control of data transactions External panic button connection for emergency calls Up to 1024 channels Open channel non-trunked operation Installation kit includes compact reversible mounting bracket Speech and data calls Individual, group and broadcast calls, PABX and PSTN calls Priority, emergency and conference calls Call diversion Unattended call-back mode Dynamic on-air regrouping KMX-T series specifications Frequency Range 80 MHz Band 08A:66-88 MHz 150 MHz Band 15A:136-162 MHz 15B:146-174MHz 200 MHz Band 20A:176-208 MHz 400 MHz Band 40C:400-440 MHz 40D:440-480 MHz Number of channels Up to 1024 Number of addresses Up to 999 selectable, up to 99 pre-set including call types: normal, group, broadcast, priority, emergency, divert, cancel divert, status, 4 and 9 digit PABX, 20 digit PSTN and open channel non-trunked Channel spacing 12.5 or 25 kHz available Dimensions 120mm Wide x 45mm High x 180mm Deep Specifications ETS 300-086, ETS 300 1 13, ETS 300 279 Signalling options MPT 1343 or MPT 1327 compatibility, open channel non-trunked operation with CTCSS as an option, MPTI 327/1343 trunking Data capabilities SDMl, SDM2, NPD; integral 1200 baud modem; RS232 program/data serial port operating at 4800 baud Transmitter RF power output High/Low 25/6 Watts Maximum frequency deviation 12.5kHz spacing: ± 2.5 kHz 25kHz spacing: ± 5 kHz Frequency stability ± 3ppm Frequency response Within ±3dB of 6dB/octave pre-emphasis from 0.3 to 3 kHz, 1 kHz reference Signal to Noise Ratio More than 40dB at 1 kHz 60% modulation Modulation distortion less than 3% at 1 kHz 60% modulation Other parameters As ETS 300 113 Receiver Intermediate Frequencies 1st IF: 45 MHz 2nd IF: 455 kHz Sensitivity less than 0.4NV pd for 20 dB noise quieting less than 0.3NV pd for 12dB SINAD Squelch sensitivity Less than 0.25NV AF response Within ±3dB of 6dB/octave de-emphasis from 0.3 to 3 kHz, 1 kHz reference AF distortion Less than 5°/ at 1 kHz 60% modulation Signal to noise ratio More than 40dB at 1 kHz 60% modulation Other parameters As ETS 300 113 These typical specifications have been prepared for world-wide markets and cover different models within the KMX-T series. Due to constant technological developments and changes, Key Radio Systems Ltd reserves the right to vary these specifications without notice. Please contact Glanford Electronics Limited for further details. The KME series of mobiles includes versions for all applications - conventional PMR and MPT1327 trunked systems - in all frequency bands from 66520MHz. This range of models from Key Radio Systems Ltd of Aldermaston (UK), has outstanding reliability and a rugged metal casing. It is available in a wide range of frequency bands and channel spacing. MPT1327 trunked models all have full data capability as standard (SDM1, SDM2, non-prescribed data) without any additional modem, together with full control by serial data for Computer Aided Dispatch applications. Mobiles are available in three standard control head versions to cover different applications: Simple operation with 16 shortcode numbers selected by rotary switch. Each can be programmed for radio, status, PABX or PSTN telephone calls. Multiaddress operation with 3-digit display and up/down buttons to give 999 selections including short codes and MPT 1343 fleet numbers. Keypad microphone for full freeform dialling, and alphanumeric display (2 lines of 24 characters) to show text for data or message paging, and full supervisory information. Our engineering teams can offer designs to meet customer specific requirements, for example data only models and custom interfaces, or alternative man-machine interfacing with different core software where necessary. The software techniques have resulted from many years experience in the research, development and manufacture of sophisticated MPT1327 equipment and systems. This ensures a very high standard of equipment performance under a wide range of conditions, on our own infrastructure or that from other sources.
