FT-8100R Cell Mod
First off you will need the Adams-2D software & a Hex editor. 
You will also need to know the Exact Mhz that you wish to 
program into your 8100R radio.Below is what you shoud get when you Hex 
Edit 
your *.rdf file 
  
  

You first need to upload some Mhz, using the 900Mhz range is the 
easiest. 
I am using the following in this example: 

433.0000 
971.7625  =  871.7625 
971.1375  =  871.1375 
972.4000  =  872.4000 
973.0250  =  873.0250 
973.6625  =  873.6625 
974.2875  =  874.2875 
975.5500  =  875.5500 
976.1750  =  876.1750 
977.4375  =  877.4375 
981.2750  =  881.2750 
981.4875  =  881.4875 

After you get the 900Mhz uploaded to the file, then you are ready to Hex 
Edit them into 800Mhz 
as shown on the right. 



In the above picture, look for the first Mhz you entered. I searched for 
9717 
because I was looking for 971.7625 Mhz.  The rest of the frequencies you 
need to change are 
just a few spaces off. Compare the picture below with the Mhz files from 
above. All you need to do is 
change the 9 into an 8. 



You will see all the changes I made in RED.  The second number does not 
get changed, but turns RED 
due to the fact that they are in pairs. Also the Red dots on the far 
right of the pic is automatically changed 
when you chang the number into an 8. 

Upload the file into your 8100R radio & you should have the Frequencies 
in the Cell band in your radio.
