I am using an iMac with iOS 10.12.6 and 3.4 GHz intel core i7 processor. In December I got the new SunSDR2 DX together with the E-Coder plus. The radio itself plays nicely with the iMac. However, it seems that the E-Coder plus is not running properly. When going to options, I can activate the LEDs and I can assign functions to the various keys. However, the tuning knob doesn't react as well as the functions keys. Is this behaviour known to somebody or do you have an idea what I might have done wrong?
