The unit is channeled internally with its own two concentric frequency selection knobs. The smaller of the two knobs has an “in” and an “out” position. When in the “in” position, this smaller knob changes the 0.1 MHz digit (0.0, 0.1, 0.2, etc.). When pulled “out”, it adds 0.05 MHz to the frequency and tunes in 0.1 MHz steps (0.05, 0.15, 0.25, etc.). The outer, larger knob changes the larger digits (1 MHz, 10 MHz). A 20–pole flatcable including connectors to connect to the RSC board is included. You will need the Radio Stack Controller Board to connect this module to your PC. The dimensions are: (WxDxH): 160x50x39 mm. / 6.3×1.968×1.535”
You will need the Mounting Set or the Radio Stack Cabinet in order to mount the radio modules.
