RADIOHF - Radio Shack DSP-40 DSP unit

For sale today I have a Radio Shack DSP-40 Digital Signal Processing unit for use with any radio. Audio noise reduction system with built in speaker. Switch selectable bandwidth (narrow, medium, wide) and selectable filter mode (Noise Reduction/Auto-notch, SSB, CW). DSP bypass switch and volume control. Great way to add narrow filtering and noise reduction to older radios.

It is in good condition and works fine. Comes with a cord to hook to the radio speaker jack, and a wall cube power supply.

Asking $32 shipped. I can take paypal/check/MO/cashapp.
