Operators Handbook and Service Manual
TEKK KS-1000
Crystal Controlled Digital Data Radio
This Manual is intended for use by both the Operator and the Service Technician and is
therefore divided into two logical parts. The operation chapter presents all the necessary
information to connect, adjust and place the radio in operation. The service chapter
provides all the necessary information and data to test, align, and repair the radio.

  • Page 2: Performance Specification

    The KS-1000 Series is available in a Low and High Band configuration. The suffix L and H indicate Low and High respectively. The Low Band radio is intended for operation between 430 and 450 MHz. The High Band version for operation between 450 and 470 MHz.

    (RSSI) Carrier Detect Level Voltage, CD Chapter 1 - Operation The KS-1000 is a Half-Duplex UHF Transceiver with crystals controlling the Transmit and Receives Frequencies. Half-Duplex indicates that the radio can transmit on a frequency that is different from the receive frequency but can not RECEIVE and...

    Pin 4, Transmit Data IN In many Modems, the Data Out Signal used to Modulate the KS-1000 is a fixed level. To allow for proper modulation of the KS-1000 a level or deviation control, VR1, has been included. If the Modem used also has a level control It should be set so that the level of...
  • Page 5 Most Modems provide a connection (Closer) to Ground to key the transmitter ON. The KS-1000 PTT line may be stitched to ground via a switch, relay, or an NPN Transistor. There will be approximately +6 Volts DC on the PTT line in the open, key up, state. It is strongly recommended that Pin 2, the minus supply voltage line be used as the ground return for the PTT line.

    The chip also has an internal oscillator and mixer to convert the 21.4 MHz IF to 455KHz, as well as a very high gain IF amplifier and limiter. There are two differences between the KS-1000 and it’s predecessor, the KS-960. The KS-1000 has a 3Watt Amplifier daughterboard, and an microphone amplifier, for a more robust modulator.
  • Page 7 Q5 is a wide band amplifier which provides enough gain to offset the filter loss but is used primarily to match the filter impedance to the input of the IC1 receiver chip. The input, Pin 16, of IC1 is connected directly to the internal mixer. Pins 1 and 2 are the frequency controlling pins of the internal oscillator.
  • Page 8 high impedance counter at TP1. TP2 in the emitter of Q3 provides a means to check for the presence of drive out of the oscillator. All of the receiver stages are supplied with a constant +B voltage from the regulator transistor Q10.

  • Page 10: Receiver Alignment

    Receiver Alignment 1) Connect the KS-1000 to the test jig, power supply, SINAD, linear detector, distortion analyzer, and the signal generator. 2) Adjust the signal generator to receive frequency and set the output level to 1mV. Adjust the modulation to 1000 Hz(*) with a deviation of 3.5 KHz (*) Note: If the distortion analyzer uses a frequency other then 1000 Hz, adjust the modulation to that frequency.

  • Page 11: Transmitter Alignment

    THIS COMPLETES THE RECEIVER ALIGNMENT Transmitter Alignment 1) Connect the KS-1000 to the test jig and to the 20dB directional coupler, notch filter, spectrum analyzer, counter and 50 Ohm power meter. 2) Close the PTT switch and note if transmitter output is indicated.

  • Page 12: Antenna Considerations

    This is natural and to be expected. 12) Connect the KS-1000 via a very short piece of cable to the power meter. Connect the voltmeter to Pin 5 (the red wire) on the 6 pin connector CN1. Set the power supply to deliver 10 Volts as indicated on the Voltmeter.
  • Page 13 covered, simple “Rubber Duck” type antenna are suitable. If it is necessary to operate over greater distances, the antenna used becomes extremely important. In all cases it is advisable to consult your dealer or to contact the factory for assistance in planning and selecting the proper antenna system.
