Thanks for sharing! There´s probably also a code for this radio to operate in the 220MHz band as it has a 144/240MHz. version. I could "open" mine to work on 220 but with Chirp Software and now it works as tri-band.
I have no idea, I'm not a technician for this radio. This was just an informational video showing how to open it up to transmit beyond GMRS frequencies. I don't know, and don't offer any other information on this radio. Please stop asking.
