It shouldn't be prohibitively hard to find someone with a laptop and a wireless network if you don't have one.
It would be nice though if there were an option to save the firmware's on the PC for later use. Even if they were .SCN files used with the old 2.0.0.7 updater. Its just nice to be self sufficient and not have to have Uniden in the loop to switch forward and back with firmware files as we see fit.
I tried the new 996XT firmware and it acts just like the 396XT update did. Higher errors on our Motorola Astro Digital system, along with digital sneezing at the beginning of receptions. I've reverted back to the old firmware versions that UPMAN has so graciously made availalble in the BC VUP updater. It'll be nice if they're always available on Uniden's system. Would like to be able to save them off locally though.
