As Kieth said, they are re-labeled Shinwa radios and they take a 2402 or 2404 EEprom.. The
programer can built with several "Off the Web" EEprom programmers.. Pony-Prg is the most popular one.
I've written a prg. to read the binary image file from the EEprom programmer.. My Prog., SHINSCXP, takes
takes that image file and creates a Ascii / Txt file that is comma delimited and can be edited with any
Txt Editor or spreadsheet program.. Process the ascii/txt file back in to the new Binary image file.. The
program only allows Ham Freq's..
