RF Impedance Bridge For Sale:

This impedance bridge is for use with coaxial cable, and
can be used to adjust matching networks, adjust antennas
for resonance, and determine the impedance of a load,
among other things.

The paper work says it is good for 100 KHz to 148 MHz,
with an impedance range of 20 to 400 ohms. In other words,
it will cover HF up thru 2 meters.

It is built from an article from the Dade Radio Club in
July 1980, and is based on the Knight-kit (Allied Radio)
RF Z-Bridge. Copies of all of these articles are included.

This particular unit is in nice shape, and includes paper
work for $35 plus shipping from Florida.

Thanks.

Subject: [DCboatanchors] FREEDOM FOR 40 Meters FINALLY!
Message-ID: <49B6B1CF.26297.BB478E@bcarling.cfl.rr.com>

MARCH 29, 2009 is the last day for Broadcasters to USE 7100 to 7200 kHz.
Hopefully most will honour their agreement.

This will be a great time for AM and CW operators who have been 
increasingly SQUEEZED on the 7000-7100 and 7200 - 7300 kHz segments 
to let THEIR voices be heard in the new segment!

I understand that both AM and CW are legal there. Can someone correct 
me if I am wrong?

= = =

With only a few weeks to go before broadcast stations are due to have 
migrated from the band 7100-7200kHz as that band is restored to the 
Amateur Service, a scan watch has begun to identify stations still currently 
using that segment.

IARU Region 3 Monitoring Systems Coordinator, B.L. (Arasu) Manohar, 
VU2UR, has been scanning the segment.

He did this for four days recently to identify 58 broadcast transmissions, their 
frequencies, times and signal strengths. The broadcasters use 5kHz 
channel spacing.

The worthwhile yet painstaking task also notes the languages of the 
transmissions including Arabic, Burmese, Chinese, English, French, 
German, Indian, Japanese, Russian and Turkish.

Adding to the complexity of the task are jamming stations, heterodynes, low 
powered regional or domestic stations and many powerful broadcasters 
using relays to cover their audience target area.

Arasu, VU2UR, says similar scanning and monitoring work may be 
necessary in other parts of the world to get a fuller picture of broadcast 
activity and he's prepared to share the spreadsheet result of his work.

Mapping of broadcasters on the 40-Meter band will be important should be 
IARU need to mount a case to fight any continued occupancy of the 7100-
7200kHz after 29 March 2009.

That is the departure date set by the World Radio Conference 2003 and 
coincides with the new broadcasting schedule for 2009.

And from N4KZ:

A new U.S. ham recently posted a question on eHam about operating on 40-
meter phone. At night, he said, he only hears strong shortwave broadcast 
stations and very few hams. Don't hams operate on 40-meter SSB at night, 
he asked? That's a good question and, fortunately, some relief is on the way 
for 40 meters -- in just a few months. And the change to 40 meters should 
be rather profound worldwide.

As experienced hams know, 40-meter phone at night can be horrible in the 
U.S. phone band because of the ear- piercing interference from foreign 
broadcast stations. Many of their signals are strong enough to nearly peg 
our S-meters and if music is broadcast, it can seemingly splatter across 
large segments of the band.

But some relief is on the way. As of March 29, 2009, foreign shortwave 
stations broadcasting on 40 meters between 7100 and 7200 KHz are to 
cease. They will be permitted, however, to continue using 7200 to 7300 
KHz. So, that will free a 100-KHz portion of the band from the terrible 
interference those high-powered stations generate. As such, the 40-meter 
band will double in size for many of the world's hams.

At present, the band is just 7000 to 7100 KHz in much of the world. (Quite a 
few countries have already given their hams early permission to use the 
band above 7100 KHz.)

The 40-meter situation -- with shortwave broadcast stations sharing the 
band with hams -- has a long and complex history. But here is a short 
version. Prior to 1938, 40 meters was a worldwide ham-only band from 7000 
to 7300 KHz. But in the years leading up to World War II, some 
governments began pushing to use part of 40 meters for broadcasting. 
Why? It's prime shortwave real estate and as the world would soon 
discover, they had war on their minds and wanted good propaganda outlets 
via shortwave radio. Hence, they obtained international permission to 
broadcast on a portion of 40 meters provided they did not interfere with 
hams in North and South America, which comprise Region 2. None of them 
ever took the non-interference issue seriously and hams in North and South 
America got stuck with terrible interference and the hams in Europe, Africa, 
Asia and the Pacific, Regions 1 and 3, lost their use of 7100 to 7300 KHz as 
a result.

This injustice was partially rectified five years ago when the World Radio 
Conference voted to evict the broadcasters from 7100 to 7200 and return 
that portion of the band to hams in Regions 1 and 3. This has no direct 
impact on us in Region 2 other than after March 29 of next year, the band 
from 7100 to 7200 KHz should be free of foreign broadcast stations and all 
the interference they generate. Although many hams around the world will 
probably continue operating SSB below 7100 KHz -- as they do now -- many 
will certainly move up into the U.S. phone band above 7125 to work us 
simplex instead of operating split frequency.

Just imagine -- ragchewing at night on 40-meter phone between 7125 and 
7200 without BC interference? Or working DX stations right on your 
frequency without having to listen down below 7100. Or, if you're in Regions 
1 or 3, you can operate from 7000 to 7200 KHz.

I can't wait.
73, Dave, N4KZ

FCC says:

After March 29, 2009, 7100-7200 kHz will be allocated to the Amateur 
Service on an exclusive basis throughout the world, except in some Region 
1 and Region 3 countries.

"As such, Amateur Service use of this 100 kilohertz will be on a de facto 
secondary basis in Regions 1 and 3 until the broadcasting service vacates 
the band 7100-7200 kHz at the conclusion of Schedule B in 2009," the FCC 
noted. "This means that amateur stations in Regions 1 and 3 will shortly be 
permitted to transmit in the band 7100-7200 kHz, if they can find a 
frequency that is not being used by an international broadcast station."

The FCC said it doesn't think it needs to update its Part 97 Amateur Service 
rules until administrations in Regions 1 and 3 implement changes to allow 
amateurs to transmit in the 7100-7200 kHz segment.

Vintage Items For Sale:

Hallicrafters S-120 Shortwave receiver For Sale:
Hallicrafters S-120 vintage shortwave radio receiver
from the 1960's. Four Bands covering 550 KHz to 30 MHz.
It has a built in speaker and antenna for the broadcast
band. An external wire antenna is needed for the short
wave bands.
The receiver is working fine.
Signals are picked up on all four bands.
Cosmetically, it looks very, very, very nice. I can not
find a scratch on it, and all of the chrome looks great.
Even the telescoping antenna that was included with it
originally is still with it, as well as the paper stickers
glued inside and on the bottom of the cabinet. Of course
the fiber board rear cover is also on it.
Paper work is included for $95.

E. F. Johnson Model 250-849 "Antenna Meter" SWR Bridge
Even though it says "Antenna Meter" on it, it is really
just a normal HF SWR bridge. It is in a black box about
5 inches long, 3 inches high, and 2 inches deep, with an
SO-239 connector out each side. The actual meter movement
is an edgewise meter movement. Front panel indicates
"Impedance 50 ohms, Power 500 watts". It is interesting
to note that the front panel is marked "Waseca, Minn. U.S.A"
with no zip code given, so that should give some indication
of its vintage.
This unit is in very nice condition.
I can not find a scratch on it; the paint is very good,
as is the lettering.  $30

B & W Model 550 A coaxial antenna switch
This model will switch up to 5 antennas, and does NOT
ground unused antennas. It has SO-239 connectors
on the sides, with the coax coming out like spokes
of a wheel.
This particular switch has the optional B & W plate
installed that has the antennas labeled with 28, 21,
14, 7, and 3.5 on the dial.
Of course it works fine, and looks OK also. $40
As above, but without the optional plate.  $38

Johnson Viking Phone Patch - Model 250-46
This phone patch is made to be mounted vertically beside the rig.
It is about 6 inches high, 2 inches wide and 3 inches deep.  It
is possible that the face plate can be removed, and it made to
be mounted horizontally, but I have not done that.  The reason
I say this is that there are feet on the bottom, and on the left
side.  Maybe the feet on the left side are to protect the rig.
In any case, it has 3 pots on the front for Null, Receive Volume,
and transmit gain, along with a switch for phone patch or
microphone. On the back is a terminal strip for speaker and
phone line.  The microphone input has the 2 pin Amphenol
connector like used by Johnson, Heath, Hallicrafters, and many
others in that era.
This one is in nice shape. Paint is original and nice and
lettering close to perfect.  No scratches that I can find.  $40

High Impedance Hand Microphone
This is a gray mic that is Hi Z, and has the 2 pin Amphenol
connector on it, as used by much of the older Heath, Johnson,
Hallicrafters, and other vintage gear. It has a PTT switch.
It works fine, and is in very nice condition.  $30

Johnson Nye Viking 250-20 Low Pass Filter
This is a 52 ohm cylindrical low pass filter with a cut off
frequency of 45 MHz and 75 db of attenuation. It is rated to
take 1000 Watts of AM, or 5000 Watts PEP SSB.  $35

Vintage B & W model 426 low pass filter
B & W TVI filter, cuts off just above 10 meters,
and will handle 1500 Watts. SO-239 connector on each end.
This is an older model that seems much heavier duty. It
weighs almost twice as much as the newer model, and looks
like it would take more power. It likely was made in the
days that plate modulated AM was the rule. $30

Special Deluxe CW Key
This key is extremely nice, and is special in its mounting.
The key itself is a Nye Viking Speedex oval base 310-001
key, which has very nice action.
What separates this key from any others is the base it is
mounted on. It is solid metal about 6 inches long and 5
inches wide and 3/4 inch thick. It weighs about 6 pounds,
so it will not move across the desk when you use it.
There is a nice beveling around the top. To put it another
way, this is a specially machined base, made for the key.
The metal appears to be copper, although it is not shiny
copper, but instead has a "patina" to it like antique items.
A layer of cork covers the bottom to protect your operating
table. There is a cable with a metallic shielded 1/4 inch
plug on it.
Certainly a one of a kind key! $99

Vintage Code Practice Key / Buzzer For Sale:
Herald Electronics Co. Model SW-12 A
"Telegraph Key with Buzzer"
This is a very vintage unit. It is in its original
box, with the paper work, with an address of simply
"Chicago, Ill", with no zip code, and not even a zone.
I would guess 1950's vintage, but of course that is a guess.
The unit consists of a code key built into a base that
appears to be bakelite. The key is somewhat similar to
a J-38 (without a shorting bar), with shiny nickel plated
knurled nuts. The key has a regular knob, and not a navy
knob. Behind the key is a round cover over the buzzer,
and behind that is a place for a single D cell battery.
The unit is complete with the original instruction sheet,
in the original box. $40

ARRL How to Become a Radio Amateur, 1970, 26th edition,
Extremely nice, close to new condition,
with many vintage ads in the back, $15

ARRL Book
"Specialized Communications Techniques for the Radio Amateur"
This book is a First Edition, published in 1975.  It is in
