Информация:

Frequency coverage : 1240 ~ 1300MHz Frequency resolution : IC-1200A 10 or 20kHz (programmable) IC-1200E 12.5 or 25kHz (programmable) Frequency control : CPU based 5kHz (or 6.25kHz) step digital PLL synthesizer Simplex and semi-duplex capability (programmable offset) Memory channels : 21 channels Usable temperature range : —10°C ~+60°C (+14°F ~+140°F) Power Supply requirement : 13.8V DC ±15% (negative ground) AC Power Supply is available for AC operation. Current drain (at 13.8V DC) : Transmit HIGH(10W) Maximum 5.5A LOW (1W) Approx. 2.5A Receive Max. audio output Approx. 900mA Squelched Approx. 600mA Antenna impedance : 50i2 unbalanced Dimensions : 140(140)mm(W) x 40(40)mm(H) x 196(211 )mm(D) Bracketed values include projections. Weight : 1.5kg ■ TRANSMITTER Output power : HIGH 10W LOW 1W Emission mode : F3 (F2 when operating with an optional UT-28) Modulation system : Variable reactance frequency modulation Max. frequency deviation : ±5.0kHz Spurious emission : More than 50dB below carrier with high output power More than 40dB below carrier with low output power Microphone : 600£1 electret condenser with push-to-talk and scanning switches (IC-1200E: 1750Hz tone call switch) ■ RECEIVER Receive system : Triple-conversion superheterodyne Modulation acceptance : FM Intermediate frequencies : 1st 136.6MHz 2nd 17.2MHz 3rd 455kHz Selectivity : More than 15.0kHz at —6dB Less than 30.0kHz at —60dB Sensitivity : Less than 0.22¡jlV for 12dB SINAD Audio output : More than 2.4W at 10% distorition with 8i2 load Audio output impedance : 4 ~ 8£2 • AFC FUNCTION The need to consider frequency drift is over with the IC-1200A/E since the Transceiver incorporates ICOM's AFC (Automatic Frequency Control) function. AFC automatically and conveniently adjusts the frequency the IC-1200A/E receives to the frequency of the transmitting station. • COMPACT AND HIGH Smaller and more compact than many conventional automobile OUTPUT POWER transceivers, the IC-1200A/E still provides 10W of powerful output on any frequency in the 1200MHz band. • SIMPLE PANEL DESIGN Even with so many sophisticated functions available, the Transceiver front panel layout is extremely simple, making the IC-1200A/E a mobile unit that is both versatile in performance and safe to use while driving. •AUTOMATIC DIMMER A built-in light sensor automatically adjusts a dimmer circuit to CIRCUIT control the backlighting of the LCD READOUT. This feature is convenient for reducing eye fatigue during night operation. • 21 MEMORY CHANNELS The IC-1200A/E introduces a large capacity memory with 21 fully programmable memory channels, placing a variety of communications functions at the fingertips of the driver. • DUAL SCANNING • FREQUENCY SCAN: FUNCTIONS Searches the entire band continuously with frequency increments specified by the operator. • MEMORY SCAN: Continuously checks all memory channels. •SUBAUDIBLE TONE The IC-1200A/E incorporates 38 different subaudible tones, ensur- ENCODER ing maximum communications coverage by allowing full access to all local repeaters. •SQUELCH OPTIONS The UT-28 and UT-29 are two new optional units specially designed for the IC-1200A/E and are ideal for handling the crowded band conditions found in many locations. • UT-28 DIGITAL CODE SQUELCH UNIT: The UT-28 incorportates a system of digital coding and decoding, that allows a “personalized” squelch to be programmed using 1 of 100,000 different code numbers. • UT-29 TONE SQUELCH UNIT: The UT-29 is a subaudible tone encoder/decoder that can be installed as an alternative to the UT-28 Digital Code Squelch Unit.
