I have a couple of Standard/Horizon HX370 handhelds. These were combination Marine and VHF Land Mobile (LMR) radios - production ceased a couple years ago. The LMR side was computer programmable, and I put a bunch of 2-meter ham (and MURS) frequencies in them. Narrow/wide selectable, repeater and PL compatible, and true 5 watt output...nice radios! And the LMR channels were right alongside the marine ones, so no need to change modes or personalities to switch from one service to the other. But without UHF they were obviously NOT GMRS, sadly.
