Both are available with either a fistmike or telephone handset, and offer the same features including channel scan, channel memory, dual watch etc. The details in this owner ’s manual apply to both models. The RT1400 model features an additional watchkeeping receiver, allowing it to use the Digital Selective Calling (DSC) system for routine and distress calling on VHF channel 70. For this the RT1400 will need to be linked to the Simrad DSC control unit DSC1400(DSC Class D). DSC com- patibility is not available with the RT1200 model. This manual describes all operating features available to the RT1200 and RT1400 models, includ- ing channel scan, which is not permitted in certain countries. Therefore this feature may not be available on the set supplied if it was purchased or configured for one of these countries. 1.3 Technical Specification Power Supply12v DC (10.8v - 15.5v DC) Channel Capability55 international channels 1-28, 60-88 simplex & semi-duplex UK : includes M (previously 37) and M2 USA : includes 0, 29, 89, 75, 76, Wx1-10 receive only.

Circuit Description - AXIS RT1200/1400 Introduction. The AXIS RT1200 consists of two PCB assemblies. The main RF PCB assembly , Navico part No. E02957, contains all the transmitter and receiver circuitry, including the synthesiser, modulator and audio power amplifiers. The control PCB assembly, Navico part No. E02960, contains the microprocessor, user controls, the LCD display and external interfaces. The AXIS RT1400 has an additional Channel 70 watchkeeping receiver, Navico part No. E03211, fitted to the main Rx/Tx assembly. There are no differences to the front panel assembly in this version. E02957 Rx/Tx PCB Assembly. The circuitry on this assembly is shown on drawing No. E02955. Receiver. RF from the antenna socket passes through the low pass PA filter to a quarter wave match/switch L5, L6 and pin diode D1. In transmit D1 is on to protect the receiver. There then follows an optional attenuator and power splitter, not used on the RT1200. In this model C214 is a 1nF coupling capacitor. L7, L8 and the associated capacitors form a bandpass filter before the R.F. pre-amp, TR1. L9 and L11 form a further bandpass section before the mixer. The RF signal is fed to the source of TR2 and the local oscillator fed to Gate 1. Low side injection is used, i.e. the LO is 21.4 MHz below the receive frequency. L13 forms the drain load before matching through C25 and C26 to the 4 pole crystal filter, XTAL1 and XTAL2. The output of the filter is coupled by L14, C28 and C29 to the integrated IF amplifier/demodulator IC1. This uses a second local oscillator at 21.855MHz giving a second IF of 455kHz. XTAL4 is a 6 pole ceramic filter completing the necessary bandwidth definition. Quadrature coil L16 provides the demodulation. Audio from pin 9 of IC1 is de-emphasised by R20 and C43, buffered by TR120 before distribution to the various audio stages on the control PCB. The audio from pin 9 is also passed through a very high gain amplifier, within IC1, configured as a band pass filter to detector D2 to provide a voltage proportional to the received signal strength. This level also goes to the control panel to provide squelch control. The AF signal is returned from the control panel after the volume and squelch controls to two audio power amplifiers in Bridge mode. The speaker output is switched at the external speaker socket to mute the internal speaker when an external speaker is connected. Transmitter. From the LO switch/buffer TR102, the transmit signal is amplified by controlled transistors TR101 and TR100, to drive the hybrid PA module IC100. This device is capable of generating the required 25Watts. The output is switched through PIN diode D100 before passing through the PA filter L1 to L4. L4 of this filter, with diodes D101 and D102 forms a simple forward and reverse power detector to provide power control and transmitter status indication on the front panel display. The power control signal is fed to differential amplifier IC101 along with the reference power signal from VR100 and VR101, used to set the hi and low powers. The output of this amplifier forms a regulated supply with TR113 and TR114 to supply the PA drivers TR100 and TR101. Note that the reference input and supply for TR114 is fed from TR111 which is only turned on after the synthesiser is in lock. Local Oscillator / Synthesiser . The main LO consists of TR105 connected as a Colpitts oscillator. Tuning is by L113 and varactor VC102. Band switching between Rx and Tx is by PIN diode D103. The output of this oscillator is buffered by a cascade pair formed by TR104 and TR103 in receive, and TR102 and TR104 in Transmit, the supply to TR102 and TR103 being switched between the two modes. The output is also buffered by TR118 to the input of the synthesiser, IC105. The reference frequency at 9.6MHz is generated by TR119 and controlled by XTAL101. C200, C115 and R157 form the main loop filter with additional suppression of the reference frequency given by R179 and C204. The synthesiser is controlled from the control panel via a 3 wire serial interface. Modulator. Audio from the control panel is amplified by IC104b. The gain of this stage is configured by R169, R173 and C169 to give the signal pre- emphasis. The output of this stage is peak detected by D3 and detector TR116 to provide a gain control signal to TR117, to provide limiting of high level input signals. Temperature compensation of the limiter is provided by thermistor TH1. IC104a forms a high pass filter to meet the 14db/octave roll-off above 6kHz. The final output is fed to the modulation diode VC101 via gain control VR102, which is set to a maximum of 5kHz deviation. Power Regulation and Switching. The 12Volt supply is switched on the front panel then feeds the audio amplifiers and regulators. The R.F. power module takes power before the switch to minimise voltage drops. Reverse polarity protection is provided by D104 and D105. A regulated 8V supply is provided by IC103 and 5V from IC107. The supply for receive and transmit circuits are switched by TR106 and TR110, controlled from the synthesiser via TR107 to TR109. IC105 controls the switching of PIN diode D103, ensuring that there a suitably high reverse bias across it in the OFF condition. 21.4MHz VCO &Buffers S y nth LockDetect IF Chip Pre-emphasis,Limiting & HPF - + D1,D100 TR2 TR1 XTAL3 XTAL1,2 D101 , 102 IC101,TR113,114 TR102-105,VC101,102,D103 IC104, D3,TR116,117 VR100 VR101 TR112 XTAL4 D2 IC1 TR120 IC105 TR119 TR101 TR100 IC2 IC3 TR115,111 IC100 XTAL101 Osc NoiseVolta g e Rx AF Out ClockDataEnable 1 Tx AF In Rx AF In 1W/25W E02955 Rx - Tx Circuitry Block Diagram To 2nd Rx L10, C214, C215 E03211 Second Receiver PCB Assembly (AXIS RT1400 only) The circuitry on this assembly is shown on drawing number E03209.
