Sb: DR-1200/9600 MOD
Alinco mods to use mic connector for 9600 baud data
TRANSMITTER
Remove R31
Remove C40 and replace with one end free and other end
reconnected to pin 7 of the VCO board. Connect a jumper between
the now free end of C40 and the hot end of C35. The Mic input is
now connected directly to the VCO.
RECEIVER
Disconnect the pink wire that goes to data output on the
mic connector from the PCB and reconnect it to pin 2 of the IF
board connector. This eliminates the low pass filtering on the
discriminator.
