Remapping a Keyboard Volume Wheel for Knob Tuning in HDSDR

Earlier in the month we showed a post where Mile Kokotov hacked together a $3 SDR frequency tuning knob out of a mouse and cheap rotary encoder.

Now over on YouTube user m khanfar shows us another cheap solution. Instead of using a hacked mouse, m khanfar uses the volume wheel on his keyboard. Some keyboards have these extra multimedia action buttons and controls but not all. He simply uses a multimedia keyboard remapping program called MKey to map the volume wheel into a scroll wheel.
