KW900EZP   EZ' Program by N2MCI
 
                              In early 2000, I found that the Kenwood 900mhz commercial radios store the Freq.
                          data in the file saved by the KPGxxD program. By editing that file with a binary editor
                          and changing the values, you can move the radio into the 900mhz Ham Band very easily.                                                            
                      
                             Although, it is simple enough to edit the file and the are programs to calculate the
                          what the data should be for a given frequency, KW900EZP ,  automates the process
                          by having you program in specific FCC Channels and then later converts them to Ham
                          Freq's... The new FCC Ch. Number Vs Ham Freq. Chart will provide you a list of
                          what Channel numbers need to be programmed in prior to running KW900EZP.
                          KW900EZP currently supports all the 900mhz Kenwood radios, but this is a work in
                          progress and enhancements are always being made as time permits.
                                 
                              For the older KW's (TK431/TK931/TK941) there is only one spot in the saved file
                          to change the freq. data and the rptr. split of 39mhz is fixed in the radio's firmware. This
                          is true even if you edit the data manually. These radio's require you to use 2 systems aka
                          banks to store the Xmit freq. & Rec. freq. separately. When using KW900EZP, program
                          the rec. freq's and also select Transmit Inhibit = Y, the normal defaults for rptr. xmit, and
                          simplex select Talk Around = Y. After you run the saved file through 'EZP, the freq's will
                          now display the correctly and the repeater input freq's have TA enabled in order to allow
                          the freq's to display properly. There is one exception, in that the TK-931 (KPG5D) repeater
                          input freq's will not be in TA mode and will display 39mhz above the input freq.. This is due
                          to the range of the VCO.  To toggle between the 2 systems, SCAN will have to be used..
                          The SCAN option is 'Last Used' and the scan dwell needs to be set to '0'..  I know its
                          not perfect, but it the best I could think of at the time.
                              
                              The newer KW's (TK-481/TK-981) will work as a normal radio should as it has a
                          separate entree for Xmit & Rec. in the saved file. The only problem will be the new Ham  freq.
                          will not display properly  for the TK-481 ver. 1 (KPG35D).  There is a mod. to the  KPG35D
                          program , which I do not have , to allow you  to directly program up the TK-481 Ver 1.
                          without the need to change the freq. data in the saved file..

                              To start in the conversion process:
 
                          _   Run the software (KPGxxD)  for the radio you have.. Program in all the FCC ch. numbers from
                              the KW900EZP freq. chart, save your work when you are completed and exit out of the KPGxxD
                              Program.
                          
                          _  From a dos, display the complete file name you just saved.

                          _  Run KW900EZP and when prompted, enter the full name of the file saved by KPGxxD. KW900EZP
                             will determine what type of program  the file was saved with and will make the changes accordingly.
                             KW900EZP will also only make changes to normal Commercial freq. data and will leave any data it
                             does not understand or any data already changed to ham freq's in prior runs.

                          _  Now run the KPGxxD for your radio and read  file back in and you should see the freq. display on the
                             bottom of window when you  select a group aka Channel. There are two exceptions to this, which I
                             addressed above.
                      
                              All of the fields on the KPGxxD program can be updated at any time,  i.e. PL, DPL, Names,
                          TA, ..., with the exception of the FCC Ch. number. If changes are made there, you will have to
                          rerun KW900EZP to get the Ham freq. back.
                       
                              At the Current time, 'EZP does not make any changes to the 'TEST' Freq's. There maybe a future
                          enhancement to change this. Any changes are posted in the AR902Mhz and 900mhz yahoo groups.
