\n I am going through the very same thing at the moment.

\n Unfortunately the controller board you have, a 628G3, is a\n 900 MHz only controller and all the ones I have seen are\n flashed with 900 MHz GE-Net firmware, even though the\n radio model # says it's EDACS (according to the Hall\n Electronics GE Tech web page.)
\n
\n You can check this with the blue button on power-up, if it\n says IO900M 12 that is GE-Net firmware. Also, if you\n connect your programming cable, the GE-Net brings up PC\n PROG in the display while the EDACS one will say URP 9600.
\n
\n Thus, it seems you will need a new front section or at\n least a new controller board which can be flashed with\n EDACS firmware. The problem with the 628G3 controller is\n that it can not be flashed with conventional firmware as\n the baud rate is not 9600 without rather tedious hardware\n modifications. That's my understanding.
\n
\n Once you get a new board or front, it is then flashed with\n the right version EDACS firmware (see Mark Cobbedick's\n instruction sheets on 900 MPA conversions) and then you\n use the modified EDACS1 DOS software to write a\n personality file with 900 ham channels. You also have to\n reset the tracking data. Thus what we need to do is 1)\n change front to other-band EDACS front or at least the\n controller board to flash-able type 2) Flash controller\n board with EDACS firmware 3) program with modified EDACS1\n and re-do tracking data.
\n
\n I am not mentioning Hamflash because it doesn't do the\n 902/927 split, which is all that we use where I am,\n doesn't do DCG (DPL,) and a few other limitations.
\n
\n The above is what I have put together after pestering Doug\n Bade and Mark Cobbeldick from this list with what sounds\n like the exact problem you have! If I am off base one or\n the other will probably chime in.

I have reviewed some of the documentation but I\n am a little confused.And what software is used as I know\n it's not Programmer or the MPA V12 software. Is it the old\n DOS EDACS software if so how do you modify it
