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

Kenwood MC-44 DTMF, Touch Tone Mic FS: Kenwood MC-44 DTMF, Touch Tone Mic For Sale:
-
The Kenwood MC-44 is a Hand Microphone with 16
digit DTMF Touch Tone Pad, and a round 8 pin
plug for Kenwood, Alinco, etc.
-
This hand mic works great on most Kenwood rigs
with the round 8 pin connector, such as the
TS-440, TM-241, TM-2530, TW-4000, and others,
including Alinco and ADI. It says "Electret
Condenser Mic" on the back, and "Kenwood" on
the front.
-
Basically, this mic functions like an MC-43,
with a couple more features. It has the mic
and PTT switch; it also has up/down switches
on the top. There are four "extra" buttons
labeled Call, VFO, MR, and PF on the front.
What these four buttons do depends on the rig.
There is also a "Lock" switch on the back.
-
Regardless if you use the four extra buttons
or not, you still have a mic that works like
an MC-43.
-
This mic works 100%, and looks great.
-
Buy it with manual for $30 plus shipping from
Florida.
-
Thanks. 73,

Included is a reprint of the manuals. $300 shipped to CONUS for the pair.
