Radio Shack DSP-40 NR Unit For Sale: Radio Shack DSP-40, Noise Reduction Unit
For Sale:
-
The Radio Shack DSP-40, 21-543, is an
external DSP unit that can be added to
rigs that lack DSP features. It inserts
in the audio line, between your rig and
speaker, to add DSP. It has three band
widths -- narrow, medium, and wide, and
has filters for Noise Reduction, CW, or SSB.
-
If your rig lacks a CW filter, this unit
will add that, with a CW filter about 350
Hz wide, centered on 750 Hz.
-
It requires 12 V DC to operate, and produces
up to 6 W of audio.
-
This unit operates as it should. If you
expect DSP the same as built in to a modern,
high end rig, this is not it.
-
This one looks really great, with no scratches
or defects.
Buy it with a detailed manual for $45 plus
shipping from Florida.
-
Thanks. 73,
Ken Simpson, W8EK

Sunken Navy Key, restored! Rare!: 1) I got this Navy key on Ebay. To me it had obviously been immersed in seawater, by the salts on the case (shown in pic), prolly from a sunken ship or airplane in the war. When I opened the cavity, it was filled w/whitish-blue salt crystals. I cleaned it all & re-touched the paint. The '26003A' couldn't be seen nor the normal base red Navy anchor stamp, I presume lost to the seawater.
2) Also in the picture from an angle which shows where the seawater had eaten into the side of the case. (See pic) Oddly enough the stainless steel areas looked untouched! The screws in the pic are original!
3) I took 2 new pix after the key was mounted on marble and a jack added. It works fine on a recent ham radio.
Sell $175 shipped CONUS (PAYPAL preferred, others ok). Will trade for Kent SP-1 key, Etc. [A letter of verification / validation w/all 4 pix will be included with the key.]; Listing #1760055 - Submitted on 02/24/26 by Callsign AC5D - IP: dynamic-23-151-80-67.tekwavisp.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
For Sale: Generator: Greetings. I have for sale an ALL POWER 10,000 WATT DUAL-FUEL GENERATOR. Comes complete with owner's manual, keys, and propane tank attachment hose. Has new battery and thumbwheel battery terminal cutoffs so the battery doesn't drain when not in use. Comes with a Predator cover to cover the generator if it's outside. It may need a new carburetor. It starts using starting fluid but then it shuts off. Bought this brand new 1 year ago and has little time on it (approximately 2 hours) Moving to another location to where I won't be able to have the generator so it must go. I will sell this to someone who is mechanically inclined and is willing to service the carburetor or simply put on a new one and have the needs for a generator. Paid $1,150.00 brand new asking $650.00 O.B.O.(within reason) Terms: CASH ONLY!!! --->I WILL NOT SHIP THIS GENERATOR<--- It is for --->PICKUP HERE ONLY<---.
