Description
Unlike CTR2-Dial firmware or CTR2-MIDI which are one-way MIDI controllers, CTR2-Duo, running CTR2-Flex firmware connects directly to your Flex radio using the Flex API over WiFi and works with all Windows, Mac, and iOS versions of SmartSDR. In fact, it can even work along side other CTR2-Uno, CTR2-Duo, or CTR2-Quad units connected to your radio with each controlling a different slice.
CTR2-Flex firmware does not support SmartLink. For remote operation with SmartLink you can boot it into CTR2-Dial firmware* and use it as a MIDI controller with SmartSDR for iOS/MacOS.
CTR2-Duo 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. The CW paddle input jack can also be used for a straight-key (or external keyer) and a PTT switch.
The knobs on CTR2-Duo are detent (bumpy) type because these knobs are typically used for volume, squelch, RIT, and DSP control. Turn and push-and-turn actions on the knobs can be assigned two of the Dial functions. The build-in pushbuttons on each of the knobs can also be assigned to two Button functions when using short and long-press button actions.
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.
