Radio Shack DSP-40 Digital Signal Processor

About this listing

For sale is a Radio Shack DSP-40 Digital Signal Processor unit. I've used the unit personally and it does a decent job cleaning up audio signals, and has a built-in speaker. If mailing, buyer is responsible for shipping charges. I'm planning on attending the Milton Hamfest on Saturday, July 11, 2026 and would be happy to pass the (paid-for) item to the buyer free of charge at the event. The item is located in Toronto, and if you're out of town, I'm happy to hold the (paid-for) item until you have a reason to visit. Feel free to make a reasonable offer!:) Thanks for looking, and feel free to contact me with any questions!
