I just did the upgrade to my P3 with the SVGA card, without any issues. PC with a "real" RS-232 port, Windows7 64-bit, P3 Utility 1.12.4.26
First I did the upgrade to 1.20, then to the 1.24 Beta. No problems - maybe an idea to downgrade the P3 utility? _____________________ 73 de LA8AW - Odd-Egil _____________________ On Sun, Jan 20, 2013 at 1:56 AM, Bill K9YEQ <[email protected]> wrote: > Paul, Perhaps the downloaded firmware failed.
