A portable radio (100) has a control assembly (110) with controls to operate the radio. The portable radio (100) includes a radio housing (101) with a control interface (103) oriented along a particular plane. Two rotary control knobs (122, 124) are attached at the control interface (103), and have respective base portions (123, 125) separated by a first spacing, and respective top portions (132, 134) separated by a second spacing. The second rotary control knob (122) is angled to cause the second spacing to be substantially more than first spacing.
