Microphones and related items For Sale:

All of these microphones have been tested and work well.

Johnson Hi Z Hand Microphone
This high impedance hand mic is a gray color, with the
Johnson logo with the Viking on it. It has a PTT switch and
coiled cord, and produces a nice pattern on the scope. It
looks good also. $30

Generic Hi Z Hand Microphone
This hand mic is black in color, and looks like it might
have come from a HyGain rig. It has a PTT switch and black
coiled cord. $25

Kenwood MC-43 S hand microphone
This is the "standard" microphone that came with many
of the rigs that take the round 8 pin mic connector that this
one has on it.  It has "up" and "down" switches, as well
as the normal PTT switch.  This particular MC-43 is in
extremely nice condition. $40

Shure 401 B, Low Z Hand Microphone
This mic has characteristics similar the the Shure 444
Desk Mic, but this one is a hand mic. It is a controlled
magnetic mic, with frequency response tailored for voice
communications. It has a rugged case, and a heavy duty
coiled cord. 4 pin connector. With paper work for $40.

Shure 104 C, Low Z hand Microphone
This is a very heavy duty Shure mic. It appears to be new,
with stripped and tinned ends that have never been on a
connector. It is in its original box, with the original
instruction manual. $30

Chrome Low Z Hand Microphone
This mic is chrome plated. My memory says it may have come
from a Polycom rig. The mic is a good solid metal case with
chrome plating all around, with a black PTT switch and black
coiled cord. There are some pits on the chrome; it works
fine. $30

Generic Hand Microphone
This is a low impedance hand microphone, black in color.
With 4 pin connector. $25
With no connector. $22

Lafayette EAM-15 dynamic hand microphone
2000 ohm impedance can be used any place a dynamic mic is
needed. Stripped and tinned leads.
It works fine, and looks good also. $25

DTMF Touch Tone Microphones:

KDK DM TT-1 DTMF Touch Tone Microphone
This mic has a 12 digit touch tone pad on it, along with a
switch to turn the pad on and off. I presently has a 4 pin
plug on it, and can be used on most any rig. It works fine,
and looks great. $35

CES 655 L "Microdialer" DTMF Microphone
You can manual dial a number, or automatically have it
stored in the mic, and "speed dial" with this mic. 12
digit touch tone pad on the front, with the microphone
part above the pad. This one presently has a 4 pin plug
on it, but of course that can be changed. $35

CES 600 L, Universal DTMF microphone
This has a normal touch tone pad on the front, with
a low impedance microphone. This one has the 8 pin
modular plug (like a computer LAN) on it. This mic has
not been used, so it is in really great condition.
With paper work for $40.

Data Signal "Data-Coder 5" touch tone mic
This mic has a 12 digit touchtone pad on it, plus a
normal low impedance microphone. With 4 pin plug.
Like new. $38

Communications Speaker
This 4 inch square speaker is optimized for communications
frequencies (300 to 3000 Hz). It is in a black enclosure,
and is an 8 ohm speaker. It has a cord with a 1/8 inch
(3.5 mm) mono plug on the end.
This one works fine and looks OK also. $15

B & W 377 Coaxial Antenna Relay:
I had never seen one of these before. Most of us are familiar
with the Dow Key Antenna relays that many of us used 40 or 50
years ago. This unit serves the same function, but is somewhat
The B & W 377 is housed in a hexagon box. It has three SO-239
connectors coming out three of the sides, a length of wire on
one side that goes to the coil of the relay, and two sides that
are blank.
The coil is rated to work on 48 to 130 volts AC. The original
single page instruction sheet says that it is a unique relay
design permitting this large variation in voltage. It is good
to 150 MHz, and will handle 2000 Watts PEP, or 1000 watts
It appears that this unit has never been used. It has the
original instruction sheet, and original box. The unit itself
does not appear to have been used, and looks perfect. $75
