There are so many websites out there 'how to program Kenwood TK-240'. All of the ones I have seen have incorrect or incomplete info and dont work. I have been trying to program my TK-240's for literally months, so I've seen nearly every TK 240 page on the web. The data on this page has been used to program my 240's and it should work on your radio too... Please let me know if it doesn't work on your radio (click the contact link above).
** IMPORTANT NOTE: I have found some possible errors in this data, Please ONLY follow the SELF PROGRAMMING info at the moment (as this is confirmed correct) **
The Kenwood TK-240 can be programmed either by plugging it into a computer and writing the programming data to the eprom, or it can be 'self programmed' without the need for a computer. I have never been successful in getting the radio to communicate with the computer, but thats not really an issue, as in 'self programming' mode all of the radio's 16 channels can be programmed with RX frequency, RX CTCSS, TX frequency and TX CTCSS which will suffice for most uses.
You can also put the radio into 'Dealer Settings' mode, Where you can set up many other things (when I have worked out what all the dealer mode settings do, I will list them here). Be very carefull what you mess with in dealer settings mode as you can easily make the radio unuseable if you mess up the settings.
First, I will discuss the availible programming modes, and then I will tell you how to get the radio into each mode. This info will also work on the Kenwood TK-340 (UHF version) as the CPU board is the same in both radio's
All of the info on this page is copyright to me as I have spent hours working it out and piecing it together from little bits of correct info from several different sources. Please link to this page rather than copying my info to other websites.
