Here is a quick a simple little drill for improving our knowledge of our portable radios, without even picking one up. Needed for the drill: Piece of blank paper for each member, a pencil, and hopefully, the memory is up to the test.
Every member gets to draw a rough picture of the portable they carry, including all pertinent buttons, knobs, bands, and explain all. When everyone is done, get a radio and compare how the crew has done.
Each members keep the drawing, for review at a later day. Simple and easy, the end results are interesting and a review we all need from time to time.
