I got mind off Amazon, bought the 3 pack. For whatever reason, the software will not read from the radios, so if you want to program them differently, you'll need to save the file for each and then write over the current config. I got my firmware off the Retevis site: https://www.retevis.com/Retevis-RT76P-GMRS-Radio-Portable-Walkie-Talkies/#A9180BX1-C9034AX1 As for NOAA, even when I manually enter them in frequency mode, it still doesn't receive. Hopefully they release another firmware update soon to fix it.
