Emergency communications administration specialist Rob Radtke is back to discuss duplex communications and more with us in part 2 of "On the Radio with Rob."

Several members of our Warner family attended the annual Hytera US Dealer Conference in Dallas, Texas last week where they accepted the Platinum Dealer Award.

Rob Radtke gives us a brief history and overview of two-way radio in this first installment in a short series we’re calling “On the Radio with Rob.”
