    Has anyone tried programming a 5100 series with a true EFJ USB cable? (that's one made and sold by EFJ) I am using PCC 1.28.0.8 and I am able to read the radio, but if I try to save the file I receive an error "Unable to retrieve ESN from Radio" I forget the excact verbage. The 5100 has 1.18.15 installed.

    I program my 5100s using the official EFJ USB cable and have no issues. That said my firmware is 4.x. You may need a serial cable to program a 1.x firmware radio. Its been so long since I programmed a non 4.x radio that I cannot remember which cable I used.
