KENCON-1.EXE COM1 version 1.1b compiled basic
KENCON-2.EXE COM2 version 1.1b compiled basic
KENCON.EXE COM1-COM4 version 1.1c rewritten in Microsoft C
KENCON.doc this file
No hardware modification is required to use KENCON-1 or KENCON-2 but to use
KENCON.EXE you must jumper RS232 pins 20 & 6. This can be done either
inside the IF232-c or within the cable connectors. KENCON will NOT work
without this simple modification.
KENCON-x.EXE is a stand alone compiled basic program designed to control
the KENWOOD 440s from the keyboard of an IBM-PC computer through
serial ports COM1 or COM2. It is designed to run from a single command
line or through the menus provided in the program itself.
KENCON.EXE was written in C because it seems to cause less disturbance
with other COM ports when run. Since one program will drive com ports
1 through 4 an additional command is requested to identify which port
is connected to the radio. It is not recursive like the Basic version
but that will be fixed in a later release.
By entering all KENCON-x commands from the command line the program can be
used with the new "!" DOS shell command in CPBBS software.
EXAMPLE of a typical command used in the FWD.MB file:
!b0023 <DOS shell command for port B of the CPBBS
KENCON-2 26 5 <KENCON-2.EXE command string (COM2:)
*** EOF <END of dos shell
GB0023F KB3MY <Beginning of next forward list
KB3MY
*** EOF
In the above example the "KENCON-2" runs the KENCON-2.EXE program then
picks option "26" (SELECT MEMORY CHANNEL) and finally "5" which
selects channel 5. This same kind of command sequence could be used
in the autoexec file to initialize the radio on startup. By entering
the frequency as a negative number (-14111.510) the program will
send the TUNE ANTENNA command following the frequency change. In
addition I have added a separate TUNE ANTENNA function as option 36.
For the KENCON version the above command line would be as follows:
KENCON 2 26 5
As you will see there is room for 9 additional functions in the menu
so if anyone has a wish list just let me know. I will not be adding
any functions that read information FROM the radio so don't ask for
them.
KENCON.EXE was written in C because it seems to cause less disturbance
with other COM ports when run. One program will also work with com ports
1 through 4. It is not recursive like the Basic version but that will
be fixed in a later release.
These programs were written to allow a handicapped ham control his
radio from the keyboard of his PC.
If any of you have any comments or suggested additions to the program
please let me know.
COMMENT:
One of the considerations for purchasing the 440 was its ability
to be controlled from the keyboard. Since it has a built in auto tuner,
I and many others assumed we could activate the tuner form the computer,
NOT TRUE for the 440. It seems to me that the ability to change frequencies
with the tuner is nearly useless. I have contacted Kenwood and they indicated
that I was the first to complain. If they were to receive "enough" complaints
they would consider a modification to offer tuning from the keyboard. In
my particular case I use the 440 on our Navy MARS packet net. This requires
several off the wall frequencies and tuning is a must on several of them.
For a handicapped operator this capability might mean the difference between
total enjoyment of the ham experience vs. added frustration. If you agree
that auto tuning is a much needed 440 capability, please call or write Kenwood
in California and ask them to design a modifications for us. Thanks!
