I heard Sonic over the radio across town years ago. They really had a good signal. I could not believe how well their bubble pack radios signal traveled. They had a grand opening and they were using GMRS to direct cars. I drove over and ordered a hamburger. While eating I explained to the manager that what was going on was not a good idea. FCC rules, etc. He was also unaware of the ramifications. They had just purchased the radios for the opening, I suggested that he have his staff change over to one of the FRS only channels. I showed him how and explained that 0.5 watts would work well in the parking lot. There was no need to paint the entire city with parking lot activity. It worked out well. I never heard them on the air again. I visited often for a meal every now and then. LPS
