CTR2-Duo

To eliminate confusion over CTR2-Flex hardware and CTR2-Flex firmware, the CTR2-Flex dual-encoder units have been rebranded as CTR2-Duo. There is no change in the hardware. CTR2-Duo runs the CTR2-Flex/CTR2-Dial dual-boot firmware.

• Select the type of enclosure from the options below. You can select the commercial, New Age injection molded, CNC machined enclosure or the 3D printed enclosure.
• Select the firmware you’d like your unit to boot into on delivery. You can change the boot firmware at any time from the Settings menu.

When running CTR2-Flex firmware, you can connect to, and control your Flex 6000/8000 series radio over WiFi using the Flex API. This mode is a true radio controller and includes a dashboard display where you can easily select and control many parameters on your radio. You can run any version of SmartSDR in parallel with CTR2-Duo.

When running CTR2-Dial firmware, the unit becomes a MIDI controller and can control any radio control app that supports MIDI control, including Marcus’ (DL8MRE) SmartSDR for iOS/MacOS, SDR-Control, FT-Control, TS-Control, and K4-Control. It can also be used with many Windows based control packages such as Thetis and SDR-Console, and many more.

NOTE: The  plastic knob style and color are subject to availability. You can replace the supplied knobs with any knob of your choice that accepts a 6mm knurled shaft.
