Because the UV-5RA is simply too powerful (even on the low transmission setting) for use on many FRS channels -and those are removed from this setup file. Because the FCC has determined that you now need to transmit more “narrow” on some channels than you used to -and that is “enforced” in this file 2. Disconnect and you're done! So why are these seemingly simple instructions even posted? 1. Copy and paste stations from setup file instead 5. Load stations from radio -and delete them. Download setup file (GMRS-MURS-FRS1-7-and-1-COP.img) from this site 4. Buy USB cable for it (I found mine on ebay) and install using driver from Miklor or the CD. Using Chirp (Daily build) for setting up the Baofeng UV-5RA VHF/UHF tranceiver (hopefully)legally for GMRS license holders who wants to use the FRS, GMRS and MURS channels without getting in trouble with the FCC.
