Microphones:

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

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

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

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.

normal low impedance microphone. With 4 pin plug.

Speaker Microphones:

others. It has a 3 conductor 3.5 mm plug and a 2 conductor
2.5 mm plug. $15

Azden, Icom, some Yaesu, and others. $ 20

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

Low Pass TVI Filters:

A low pass TVI filter is added to the transmitter (inserted
in the coax line after the transmitter or transceiver) to
reduce harmonic interference.

Bencher YA-1, high power, low pass TVI filter
If you need a more heavy duty filter for the output of
your amplifier, this one is ideal. It will take full legal
power plus, and has at least 80 db signal attenuation at
TV channel 2.
It is also in a very sturdy metal case with SO-239 connectors
on each end, and is a 50 ohm filter.
This one works great, and looks close to new. Someone added
some felt to the bottom, so that it protects better. It is in its
original box, with paper work. Bencher currently sells these
for about $90. This one is only $65.

B & W FL-10/1500 (Also known as model 425) low pass filter
B & W TVI filter, 50 ohm. It cuts off just above 10 meters,
and will handle 1500 Watts. SO-239 connector on each
end. This is the latest model B & W filter. It is in very nice
condition; it looks very close to new. With paper work $40.

Drake TV-5200-LP
This is the more modern version of the Drake TV-1000 Low Pass
Filter. This is the filter that may also be used on the low
end of six meters, as well as HF. It is good for 1000 Watts
average below 30 MHz, and about 200 W up to 52 MHz. It works
fine, and is in very nice shape. $35

Drake TV-3300-LP Low Pass Filter
This is a modern low pass filter to go between your transmitter
and antenna, and has been optimized to have more attenuation
in the 40 MHz region, where many TVs have their IF. It is good
for 1000 Watts "average" according to the manual, and has
over 80 db attenuation at 41 MHz. This one looks great, and
includes the paper work. $30

Phone Patches / Digital Interfaces:

Waters "Universal Hybrid Coupler II" Model 3002

Most of us would likely call this a phone patch, but it
is really much more than that. It does that, but also
will interface with a tape recorder, and permit recording
and play back of on-the-air QSOs. Nothing says that the
tape recorder input must be used that way. Connect the
sound card in your computer in this position, and you
have a very effective interface.

Model 3002 includes a speech compressor powered by a 9
volt battery. The front panel is finished on both
sides, with one side having it set in a horizontal
position, and the other in a vertical position.

This was a "top of the line" unit years ago. One only
found them with top stations such as Collins.

This particular unit is in really great condition.

With paper work for $100.

Heath HD-15 Phone Patch
This is the unit with the VU meter on the left and 3 knobs
that match the SB series to the middle and right. Low or
high Z output to the transmitter. It can also be used as
an interface to the computer for PSK31, etc. It is in
extremely good condition. No scratches or imperfections.
Paper work included for $25.

Weston Precision MilliVolt Meter Model 1
This is an extremely precision meter, with mirrored
scale about 6 inches long. It weighs about 5 1/2 pounds!
It has terminals for scales of 150, 1500, 15000, and
150000 millivolts.
Also included is the calibration information (from 1944)
indicating that it is "dot on" for calibration.
In addition, it is in an extremely nice protective case,
that appears to be real leather.
To put it another way, this is an extremely nice meter!
$80

Prices do not include shipping from Florida.

Thanks.
