Matt, if you are editing the EEproms by hand, here's a link to Mijo S51KQ's TK/R-720 web page.. I helped him with creating the EEprom (93C46) images.. See: http://lea.hamradio.si/~s51kq/temp/_projects_/TKR720_modification/
On the TKR/B radios, the file saved by KPG21D contains the data for the Freq. and CTCSS EEprom.. The 1st half of the file is the image for the Freq. EEprom and the 2nd half of the KPG21D file is the Image of the CTCSS EEprom file.. I realize binary file editing to not for everyone, but it's not as hard as everyone makes it out to be either.. I also want to create a 'EZ-Prog' type exe that will create the various file images, (TKb/r freq. & CTCSS, TK620/720/820/710/810 mobiles with and without the scan board (TK-x20's only)), from the file saved by KPG21D.. -73, Pete N2MCI --- In [email protected], DCFluX <[EMAIL PROTECTED]> wrote: > > Hello All, > > I am in the process of brute force hacking a Kenwood TKR-820 into the ham > bands.
