Power is provided from a regulated +9.5 Vdc supply and draws typically less than 4.0 mA in sleep mode. 1.2 Printed Circuit Board Numbering Convention To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a printed circuit board (PCB) numbering convention in which the last two digits of the circuit board number represent the circuit board version. For example: • PCB number 43-9120 10 indicates circuit board version 1.0. • PCB number 50002- 02 indicates circuit board version 2.0. All PCB's manufactured by Daniels Electronics are identified by one of the above conventions. 1.3 Performance Specifications Temperature Range:-30°C to +60°C. (Optional -40°C to +60°C) Supply Voltage:+9.5 Vdc, Supply Current:less 35 mA less 4.0 mA standby mode. DE DANIELS ELECTRONICS 1-2Frequency Select Handle Instruction Manual This Page Intentionally Left Blank DE DANI EL S ELECTRONICS Frequency Select Handle Instruction Manual2-1 2 THEORY OF OPERATION 2.1 General The user interface consists of an 8 digit display and 3 pushbuttons, frequency increase Ø, frequency decrease Œ, and options ̧ ̧ ̧ ̧ . On power up or key press, the synthesizer is interrogated for the current channel number and channel frequency. This information is used to generate the display, and update the synthesizer itself. The Frequency Select Handle communicates with the synthesizer using a standard 2 wire serial interface (9600 Baud, 8 bits, no parity, 1 stop bit). The command protocols are simple ASCII, both to and from the synthesizer. Another dedicated line allows the handle to temporarily wake up the synthesizer if it has been powered down. (This is currently only used on the transmitters) The Frequency Select Handle is built around a PIC microcontroller and is powered from regulated 9.5 Vdc. 2.2 Handle Operation. 1) On Power Up the following front panel indications will occur: (in order) • Daniels Banner ("Daniels Electronics Ltd") will scroll by. • The current Channel Number will be displayed (for about 2 sec). • The current Operating Frequency will be displayed ( for about 2 sec) • The display then does to sleep. 2) To display the Current Frequency: a) Press either the Ø (Frequency increase) or Œ (Frequency decrease) buttons This will display the current Channel Number (for about 2 sec), then the current frequency (for about 3 sec) The display will then go back to sleep. b) To keep the display awake, jus…

Both MT-3 systems are characterized by dependable low maintenance performance under the most severe environmental conditions. All performance measurements comply with Industry Canada (IC) Standard Specification RSS 119 and 140, as well as the Federal Communications Commission Part 87 for AM equipment. In addition, all units are burnt-in for 24 hours and are accompanied by a complete test report. The VT-3A130 Transmitter operates in the 118 - 138 MHz aviation band. The transmitter's frequency stability is controlled by an OST-3A128 Synthesizer. The synthesizer module can be programmed to have up to 16 channels. A channel programmer can preprogram the first 15 channels; channel 16 can be programmed from the front panel and channel 1 can be programmed by the four BCD switches located on the MT-3 AM Transmitter Main Board. 1.2 Manual Organization The organization of this manual reflects the modular makeup of the VT-3 product line. Each module is fully described within its respective submanual, all of which are contained within this document. In general, each submanual contains: 1. A functional description and specification summary. 2. A detailed technical description (Theory of Operation). 3. Assembly, setup and alignment procedures relevant to that particular module. * Note * Material presented in a given "sub-manual" may include information related to other module versions not directly applicable to the VT-3A130 transmitter family. The OS-3H synthesizer module is a prime example, having family members covering from 29 to 512 MHz.
