First, let me give props to the author of the 6.5536 in a toaster. Still have a couple of those around from 1995. That being said, I'm much better with phones than radios. I live in a hurricane prone zone and have been considering a radio. I figure it also might also be fun to mess with the drive thru. I've seen these radios from 120.00 for a vx-150, or 170.00 modded, then the vx1, 3, 5, and 7. Simply put, I see the obvious of several including additional bands and wattage, but am simply unfamiliar with many of the other terms. Are the models below vx5 simply incapable of drive thru fun, or just inappropriate?
