“The new MTR3b with the LCD display is a major upgrade for the Mountain Topper. The display provides frequency readout, clock with battery backup, keyer speed and battery voltage while reducing the very low current draw from 35 mA to only 15 mA. The new LCD frequency readout makes the new Mountain Topper much easier to tune. The Mountain Topper is a great “purist” radio for SOTA and other outdoor activities.” -W3DX
