Digital Mobile Radio (DMR) – The Basics

Presented by Jon Andrews, K1IMD

What is this new mode sweeping the VHF & UHF repeater spectrum all over the world?
Oh man… I was listening to a local repeater frequency and there was this horrible buzzy sound on the channel what the heck is that all about?  We will discuss some of the “buzz” and “tech talk” so you will better understand the terminology used in this new mode of operation. Radio is radio but DMR is different than radio operation most hams are used to.  We will discuss primarily the DMR-MARC network and some of the facilities associated with it.
