The LDG M-7600 provides a lavish 4 ½” meter for the IC-7600. It will display S-meter on receive, or power out, SWR, ALC level or supply voltages, all selectable from the rig’s setup menu. What’s more, the M-7600 and the virtual meter on your radio can work together; for example, you can display SWR on the radio’s meter and power output on the M-7600.
The meter face is backlit in cool LED blue, powered by any 12 volt, 250ma source; there’s a brightness control on the case back. The meter itself is passive; it doesn’t require the 12 volt supply. You don’t have to power the backlight, but you’ll be missing out on a great feature if you don‘t. Calibration adjustments are accessible from the back of the M-7600; you don’t have to take the meter apart if you ever need to cal.
