    Description

    Nice clean Radio Shack DSP 40 (21-543) DSP speaker with multiple settings/filters. It also has outputs for an external speaker or headphones for more versatility. I found the built in speaker to be pretty good for my needs so I never took advantage of these outputs. Please review the pictures as they are part of the description. Great for CB and ham radio when on air conditions are noisy. Works great but I've come up with another solution for my uses so I won't need this anymore. Been using it when the HF bands become noisy with my QRP station and it helps bring the noise level down to help with signals on noisy bands. Even when conditions are good I found it nice to have this speaker on to touch up the incoming audio. Please feel free to ask questions.
    DSP speaker and DC power adapter only. No patch or audio cables included.
    Sold as is no returns or guarantees but please contact me with any issues before leaving feedback and I'll do my best to help.
