How are linked GMRS repeaters less cumbersome than ham radio?
With eight repeater channels in total, and untrained users operating in panic mode on both the repeaters and on the eight simplex channels that share frequencies with those repeaters, linking GMRS repeaters, except on a prearranged published schedule like an amateur radio sked or net, could be useless. You're better off using personal services for proximate communications and get your news from battery powered receivers capable of tuning HF and the broadcast bands.
