Computer tuning knob
It sounds a bit illogical - because there would be a debug button on the computer? However, the button is not used to tune the computer, ale TRX-u (RX-u) attached to it. Controlling the RIG from a computer had a weakness in this area - whatever method was used, it could never fully replace the feeling of actually turning a tuning knob. Griffin Technology came up with a solution in the form of the Griffin PowerMate tuning knob.
The Griffin PowerMate connects to a PC via a USB interface. In addition to turning, it can be pushed (and rotate at the same time), which enables one of the predefined functions to be activated. For example, increasing the tuning speed is ideal.
The price of the Griffin PowerMate is 45 USD. Details can be found on the manufacturer's website: www.griffintechnology.com
