Lynovation is a small business that designs and manufactures unique, inexpensive radio control products and kits for ham radio operators. My goal is to provide useful products that you’ll use everyday because they make your station easier to use. This page summarizes each product and has links to other pages that provide additional information.
All of my products can be purchased in my online Shop.
In addition to this website I encourage you to join the CTR2 Group IO group (https://groups.io/g/CTR2). This is where I post updates and the latest firmware and manual files.
CTR2-Dial
CTR2-Dial is the newest member of the CTR2 family. Built on the code base for CTR2-MIDI (described next), this unit does everything CTR2-MIDI does, and then more! It is based on the M5Dial from M5Stack and has a built-in touchscreen. Choose from several enclosure options, or build your own. Find out more about this exciting option here.
CTR2-MIDI
If you already use a radio controller app like Marcus Roskosch’s (DL8MRE) apps for iOS and MacOS, Remote Ham Radio to operate contest quality remote radios, Thetis for your Apache ANAN or Hermes-Lite 2, or SDR-Console on Windows, CTR2-MIDI will provide an 8 function tuning knob, 6 programmable function buttons, and a multi-purpose paddle input jack. It’s small, only 60mm x 60mm x 20mm (2-3/8″ square and 7/8″ high) not counting the knob. This unit supports USB and Bluetooth-LE MIDI and is specifically designed with hams in mind. It’s simple to operate and is available fully assembled or as a kit. Your radio controller app provides the user interface. If you’re using the Marcus’ or RHR apps you can use the paddle input on CTR2-MIDI to control the keyer remotely. You can assign the controls on CTR2-MIDI to the app functions you want to control.
You can find a video introducing CTR2-MIDI here. For more information, visit the CTR2-MIDI page.
CTR2-Micro
The Micro shares the same DNA as the original CTR2-Mini but is much smaller, more rugged, less complex, easier to build, and less expensive. CTR2-Micro fits in a 60mm x 60mm x 20mm (2-3/8″ x 2-3/8″ x 7/8″) enclosure so it can find a place on even the busiest shack operating desk or in your POTA go bag.
Unlike other remote radio control knobs, CTR2-Micro is a full featured controller that works on a variety of radios. If you currently use a computer based control program with mouse control you’ll appreciate that CTR2-Micro doesn’t have to be “in focus” on your computer to control your radio. It can be just a remote frequency control knob, or if you want more control, open a terminal or browser session to “display” CTR2-Micro’s control menus. These programs don’t have to be in focus for CTR2-Micro to control your radio.
You can learn more about the capabilities of CTR2-Micro here.
You can view a short video on YouTube demonstrating the Micro’s hardware and user interface features.
