I looked at Pennsylvania's bill, and see that the exemption for Amateur radio was removed, so it applies, as written, to all mobile radios.
However, this part may actually be interpreted such that a mobile radio is allowable, provided you aren't switching channels and are simply talking using a hand held mic, pushing only one button. So it may be okay. I will take it as such. This wasn't in the earlier iteration of the bill. It has passed and has been signed by the governor.
"
Defines the use of an interactive mobile device as using at least one hand to hold, or supporting with another part of the body, an interactive mobile device, dialing or answering an interactive mobile device by pressing more than a single button, or reaching for an interactive mobile device that requires a driver to maneuver so that the driver is no longer in a seated driving position, restrained by a seat belt."
