Well, it's a wee bit off with the GMRS radio. Measured 462.659177Mhz vs the assigned 462.6625Mhz frequency using the prescaler plugin. Considering this is an FM band that has 25Khz channel separation, it's in the ballpark. Still, I cant complain that a frequency counter more than 50 years old still works that well.
