installing and benefits of newest radio

Radios are always a YMMV... Most of the time to 90% of the people the newest is the greatest but occasionally there is the crowd that says some of the older radios work better in their area of the world. Just depends I guess on your device and the quality of radio signal in your area.
 
i tried to flash the radio zip and the installation said it was a bad file and aborted the install...is there a mirror site for the downloads....actually downloaded and flashed a few times...still bad file
