Yep, you're right on both counts. THe shacks couldn't be expanded, and
icoms could. As I recall, that was one of the specific design changes
radio shack insisted on. I sold commercial two way back in those days,
and you're absolutely right as far as the selector knob. BTW, they also
made a verson for air craft band which was a cool radio with some
additional navigation stuff.
