General Mobile Radio Service (GMRS) was created decades ago, but recent FCC rule changes, licensing, and a multitude of GMRS radios make it easy to jump in the GMRS radio communication. GMRS requires a license without having to take a test, thus opening up anyone to get into radio communications. For amateur radio (HAM) enthusiasts, GMRS provides a radio communication solution for family members that don't have a HAM license. Since GMRS and HAM radios and frequencies are similar, the path to amateur radio from GMRS is an inexpensive way to jump into the hobby. Technical Guide to GMRS covers all the basics of GMRS, tools, and resources to get started.
