Although I really like the Kenwood TH-D74 for its long list of features, being an HT, the user interface is not well suited to satellite operations. In particular, for linear satellites where I may need to continuously vary the tuning throughout the pass, it is tough to come up with a good mounting scheme on my chest rig so that the tuning knob is accessible and the screen is viewable. To try to solve this problem, I thought I could somehow build an upward facing display so I can mount the radio vertically and have access to the knobs and a good display. The photo above shows the final product for this project which is built around a Raspberry Pi Zero W and the USB interface the TH-D74 supports.
