MODIFYING TS430S FOR AMTOR/PACKET ================================= "IF Board" 1) Change C164 from 0.22uF to 0.01uF. 2) Change C60 from 10uF to 4.7uF. 3) Change C57 from 0.47uF to 0.1uF. 4) Remove C58. 5) Remove R97 and replace with wire link. 6) Change R96 from 100k to 47k. 7) Locate 3 spare switch terminals on the 1MHz band switch. 8) Connect middle contact to earth. 9) Lift earthy end of C159 and connect to N/C contact with length of wire. 10) Connect lenght of wire from N/O contact to cathode of D45. 11) This switch when pushed in speeds up the AGC for Amtor/Packet use. 12) If you are useing a CW or SSB filter add 10uF across C10 or C8 depending on what filter in use, this removes switching clicks.
