Programming Kenwood TK-941 by W7UVH

Program the radio using the Kenwood program, KPG25D and KPG4 programming cable 
with all of the ctcss tones you desire and all other functions. Use FCC channel
number 200 in all systems. This will indicate frequency 937.5000. Save this 
file and exit program.  Run the program, Kenwood3.EXE.  Select the TK-941. 
Enter the frequency of the FCC channel 200, which you used in the programming. 
That frequency is 937.5000. Entered, you will see the binary code is 08 9B. 
Enter "Y" for another frequency then enter a frequency you desire. Write down 
the 4 digit binary code and continue until you have all of the codes you 
require for the number of  "FCC 200's" you entered in the programming program.
Run your Hex Edit program and load the file ***.910 you created when you 
programmed the TK-941. In lines 20, 120, 220, 320, 420 and every 100 on, you 
will see the FCC number 200, 937.500, binary number, 08 9B, every where you 
enter "200". If you have entered 200 as several groups in a system, you 
will  see them in the same line. Now you may start replacing those binary with 
the one you have written down as the frequencies you want. When complete save 
as the same name or change as you wish. Exit and reload the Kenwood program and
load the program you just saved. Check each system and group to make sure you 
have the frequency you want.  DO NOT attempt to edit the FCC number 
selection. The result will be that it goes away....and you will have to edit 
the file again..  Remember that the Frequency you enter will be the 
Receive frequency and the Transmit will be 39 mhz below that frequency. Not 
Good! Remember to use T\A in the original programming.  You will transmit 
and receive on the same frequency. All of the transmit frequencies should be 
programmed into one system, each receive frequency will be an individual 
systems. Select "Last Used" in the program. Select the transmit system and the
repeater input you want, turn on the scan and you are ready to transmit. Let 
up on PTT and the radio scans to the repeater output. DO NOT transmit while 
receiving or you will be moved to that frequency. Wait for the repeater to 
drop and resume scan before transmitting.  I have come up with a way to 
keep from transmitting while receiving but involves pulling the PTT jack, 
drilling out the PTT ground, reinstalling it and adding a 2N2222 to keep 
collector high while receiving.
