TS440S

     These Instructions are TS-440 specific, but the basics also apply
to the TS-940, TS-811 and TS-711.

     It is possible to save yourself a few dollars and lose nothing in
quality by buying the parts to upgrade your Kenwood radio for computer
control. Just purchase the parts were you find them and install them
using the instructions in the Radio's Manual.

     IC 54 is a uPD-8251-AC   Serial Communications Interface.
                Commonly called an 8251A    ($1.89 Mail Order)
     IC 55 is a TC-4040-BP    12 Stage CMOS Divider.
                Commonly called a 4040      ($0.69 Mail Order)

     The IC-10 Interface Kit from Kenwood Contains ONLY these two parts
and less instructions than are in this file.  The only thing you are
going to miss, is the $22+ price tag on the IC-10 Kit.

 Signals are    TTL levels  (NOT RS-232)
Baud rate is    4800 (1200 Opt.)
   Format is    ASCII Serial;  1 Start, 8 Data, 2 Stops
   The Baud rate may be changed to 1200 Baud by removing jumper W50 and
installing a jumper from the left pad to the center pad as viewed from
the front of the radio.  This will become obvious once you have the
radio opened up.  Many other Baud rates are possible, just look at the
schematic.
