Sorry, I do not know enough about electronics to answer those
questions....however, I CAN tell you that when I key in on CH 19, and
ask for a radio check, someone must hear me, because my needle swings
over pretty far after a few seconds. I get sound from an external
speaker plugged into PA spker, and EXT spker for weather band, just
not CB.
