Isolated: 

Isolated keying outputs are   also 

provided by two relays K1, and K2. The  
relays are operated by the collectors  of 
transistors Q1 and Q2                                                                                      

 

          Baseband Output: 

 

 

          This output may be used  to   binary 

frequency shift and RF transmitter if pro- 
vision is made in the radio  to directly  FM 
the crystal oscillator. Output is 
adjustable

 

over the range of -8 V to +8V. 

The output offset can be adjusted 
over the same range. 

     Baseband Bit Rate: 

Programmable from 10 to 300 bps 

with accuracy of 0.1% or  0.1 bps, 
whichever is  greater.
