Antenna Tuners, Headphones, Microphones, Low Pass TVI
Filters, Dual Triode Tubes, Variac, and more For Sale:

MFJ 989, 3000 Watt rated, HF Antenna Tuner:

The 3 KW MFJ-989 features two massive transmitting capacitors
and a roller inductor with a three digit counter. You won't
have arcing problems with this roller inductor, because firm
springs put considerable pressure on a plated contact wheel.

You can tune your SWR down to the absolute minimum from 1.8
to 30 MHz, including MARS and the WARC bands. It has a super
heavy duty balun for balanced lines.
You can select two coax antennas direct or through the
tuner, balanced line or random wire, plus a built-in 50
ohm 300 watt dummy load. A wattmeter is also included.

This one works fine, and looks good, although there is
some slight wear. The meter light has burned out. Paper
work included for $175.

TenTec 229 HF antenna tuner:

This roller inductor tuner will handle full legal power.
It uses an "L" match instead of a "T" match, which means
there is only one spot that will give the correct match.
The "L" match is also more efficient. Electrically, it is
the same as the 238 series, 229 A, 229 B, and 4229.

There is also a built in wattmeter with full scale reading
of 200 and 2000 watts. It also has an SWR bridge with
lighted meter, plus a 4 position antenna switch.

It can be used on any HF frequency, including the WARC
bands, as it is continuously adjustable. It has a built
in internal balun, so open wire can be used.

Cosmetically, this unit is the color of the earlier Omni
series (Omni 546, series A, B, and C) with the black vinyl
covering, and nice aluminum trim around the front.

This particular unit functions 100%, and looks perfect.
I can not find a scratch on it.

Paper work is included for $325.

Doublet Antenna and "Window Line":

Doublet antenna consisting of about 110 feet of wire, with
center insulator, 2 end insulators, and 2 center supporting
insulators. This antenna is made to be fed with "open wire"
450 ohm transmission line, and used with an antenna tuner.
It should be able to tune from 80 thru 10 meters, with the
proper tuner. $20

"Windows Line" 450 ohm transmission line
This is similar to "open wire" transmission line, but has
some plastic insulation on it instead of being open, so it
is protected more. The openings look like windows, hence
the name. I have three lengths available. Two are about
50 feet long, and are $15 each. The third is over 80 feet
long, and is $25.

Kenwood HS-4 Communications Headphones:

The Kenwood HS-4 is a set of headphones that completely
cover the ear to block out extraneous noise. They are
designed for communications effectiveness, and have an
8 ohm impedance to match most any rig. Of course these
are mono headphones and not stereo.

They have a standard 1/4 inch plug.

These work fine and look very good as well. No rips or
tears in the headphone covers. $30

Shure EM-33D, controlled magnetic hand microphone:

The Shure EM-33D was used by GE on many of their rigs.
This mic has a controlled magnetic cartridge, similar to
the Shure 444 desk microphone, but this one is a hand mic.
Apparently it is tailored for voice communications "punch"
like the 444's.

This one works fine and looks OK, although it does show some
use. It presently has a 1/4 inch stereo connector on it as
used by early TenTec, Swan, and many others.

The cartridge alone is worth $40. Buy this entire mic for $40.

Kenwood MC-30 noise canceling hand microphone For Sale:

The Kenwood MC-30S noise cancelling mic is used on many of
the older Kenwood rigs, including the TS-120, TS-130, TS-520,
TS-820, and many, many more.

Most had a 4 pin connector, but this one has a 5 pin connector
on it. It looks original. Apparently this was the original mic
on the Kenwood TR-7600/7625, and maybe others. The 5 pin
connector also matches some of the 10 meter ham rigs.
Of course the connector can be changed.

The mic works fine and looks very close to new.

Paper work included for $35.

Heath HM-15 SWR Bridge:

This is an HF SWR Bridge, with SO-239 connectors on
the back. The front has the meter on the left, and two
knobs to the right. It is the same size as the HD-15
phone patch.

This one works fine and is in nice cosmetic shape.
I can not find a scratch on it.

Paper work included for $20.

Heath HD-15 phone patch / digital interface:

This unit can be used to interface a sound card in a
PC to your transceiver. It was originally designed to
be used as a phone patch, but many have converted them
to a digital interface.

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. The meter makes it great
for setting levels.-This one is all original. It is in great condition.
Paper work included for $22.

I also have parts from a Heath HD-15 phone patch available.
This includes an audio transformer used for digital
interfacing, VU meter, and other parts. Outer cover and
knobs are gone. What do you need?

Low Pass TVI Filters For Sale:

A low pass TVI filter is added to the transmitter to reduce
harmonic interference. All have SO-239 connectors, are 50
ohm filters, and include paper work.

Bud LF-601 low pass filter
This filter is adjustable for best attenuation in your particular
situation, and also to more closely match your specific impedance.
It cuts off at about 52 MHz (if adjusted as such) so it can be
used on 6 meters, and will handle 1500 watts. $35

Bencher YA-1, high power, low pass TVI filter
If you need a 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. This one works
great, and is in its original box.
Bencher currently sells these for about $90. Only $60.

Bencher YA-1
As above, but not in original box. $45

Drake TV-1000-LP Low pass TVI 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 W "average" below
30MHz, and about 200 W up to 52 MHz. With paper work for $30.

Drake TV-1000
LP Filter as above, which functions fine electrically, but looks
ugly. With paper work. $25

Drake TV-3300-LP Low Pass Filter
This modern low pass filter 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

B & W FL-10/1500
This filter cuts off just above 10 meters, and handles 1500
Watts. It is the latest model B&W filter.In very nice condition,
it looks close to new. $40.

Para Dynamics PDC 1089
This filter is rated at a full Kilowatt, up to 30 MHz.
5 x 6 x 2 inch black box, instead of the more familiar long
enclosure. It looks like new. $25

Dual Triode Tubes:

I found some 12 volt dual triodes from a silent key.
They are all NOS (New, but old stock).
These are quality US tubes, and are priced at about half
what they are sold for by others.

I have multiple tubes of each.

12 AT 7 - $6 each
12 AU 7 - $8 each
12 AX 7 - $10 each

Powerstat (Variac) Variable Autotransformer:

We all call these Variacs, but this one is made by Powerstat.
It is their model 21, rated at 3.75 amps, 530 va, up to 140
volts AC.

This one is housed in a nice grey hammertone box, with a line
cord in, power switch, and binding posts for output. Of course
it also has the large (about 5 inch) knob, with the graduated
scale on it.

This would be ideal for bringing some of the older rigs up
to power slowly.

This one is in very nice condition, for $40 plus shipping
from Florida. It would ship in a postal service "flat rate

I also have many other accessories available such as many
different types of microphones, HTs, VHF and UHF rigs, HF
and VHF/UHF antennas, etc.
Just too many to list here. Please e-mail your requests.

Prices do not include shipping from Florida.
