- Fog 17 data terminal and peripheral circuits 7
- Pr1 is the 1200bps data communications reception out put it outputs the fm detection circuit output through an af filter ic251 output is controlled with the mute switch q252 according to whether squelch is open or closed see fig 17 7
- Pr9 is the 9600bps data communications reception out put it outputs the fm detection circuit output through an af filter ic251 these signals are always output whether the squelch is open or closed 7
- Reception signals 7
- Squelch signal output circuit 7
- The squelch circuits is input to the tnc to prevents con flicts from occurring between simultaneous receive mode and transmit mode traffic during packet communications only during 1200bps the signal is output from pin 29 of ic101 to the data terminal the logic is as shown in the table below 7
- Transmission modulation signals enter from pkd of the data terminal cn2 the path to the modulation depends on whether communications are 1200bps or 9600bps mode for 1200bps mode the transmission modulation signals from single analog switch ic204 pass through mic amplifier ic201 202 and summing amplifier ic203 and go to vco x401 through d a converter ic161 for 9600bps mode the transmission modulation signals from single analog switch ic205 pass through summing amplifier ic303 go to tcxo x401 and vco through d a converter ic161 see fig 17 7
