Description
CTR2-Quad includes a touchscreen display that doubles as a control surface offering virtual Dials and Buttons that allows you to easily change the frequency and settings on your radio. The Dashboard page brings all of the controls to a compact, easy to navigate control page.
CTR2-Flex firmware has a built-in keyer and sidetone. All models support CW paddle input so you can connect your CW paddle to operate CW over your network connection. CTR2-Quad has a separate 3.5mm (1/8″) stereo jack to connect your straight-key (or external keyer) and a PTT switch.
The three small knobs on CTR2-Quad are detent (bumpy) type because these knobs are typically used for volume, squelch, RIT, and DSP control. The large knob is a no-detent (smooth) encoder because it’s typically used for VFO control. Turn and push-and-turn actions on each knob can be assigned two of the Dial functions. The build-in pushbuttons on each of the knob can also be assigned to two Button functions when using short and long-press button actions.
CTR2-Quad is only available in a 3D printed enclosure.
NOTE: The M5Dial has a built-in 12-detent encoder that is not counted in the knob count but it can be assigned a to dial function.
* This unit ships with CTR2-Flex v2 firmware. This firmware can boot into CTR2-Flex or CTR2-Dial. The firmware boot option can be selected in the Settings menu.
