The KS-960 is a Half-Duplex UHF Transceiver with crystals controlling the Transmit and Receives Frequencies. Half-Duplex indicates that th

In many Modems, the Data Out Signal used to Modulate the KS-960 is a fixed level. To allow for proper modulation of the KS-960 a level or deviation c

A Microampmeter may be connected directly to Pin 8 to indicate the relative strength of the received signal. The circuit has a dynamic range of about

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.

All of the receiver stages are supplied with a constant +B voltage from the regulator transistor Q10. This voltage can be checked at

The base voltage of Q8 is held constant by the Zener Diode D9. The emitter voltage of Q8 is then a constant value around 5 volts. This 5
