Locked New File in "Files" section

 

开云体育

I just uploaded a new PDF file of a Hallicrafters offering in the “Files” section.? It is a shortwave wheel and an offer

for a complete shortwave listening kit including a (4) band receiver.? However, no where on the

offer can I find what receiver is offered.?

?

Anyone know which one they were offering?? And, on the second page, the post card gets

sent to the Robert Maxwell Company.? Who were they?

And more importantly, this site is dedicated to the large number of fans, cheerleaders and users of this wonderful equipment which utilized the technology of vacuum tubes.

Hallicrafters equipment was on the front lines (literally) during the early years with military communications radios. On the home front with shortwave receivers, amateur transmitters and home entertainment equipment. Truly an American company.

Locked Ham Radio Musical Promo

 

I just uploaded a vidoe file "Clip" into the files section. Click on
it and you will be entertained by the best ham radio promo I have ever
seen. It is fabulous and is not dreery like the ARRL promos. It is
very entertaining.

Apparently alot of people are watching it so you may see server errors
pop up and you will have to try again or at a later time. I encourage

Locked Subject: 70th Anniv. FM Armstrong

 

Yesterday marked the 70th Anniversity of the first
demonstration of FM radio by it's inventor Major
Edwin Howard Armstrong. I thought the Hallicrafters
folks would be interested in this, because of this
man W2XMN many things were accomplished in the
world of signal transmission. He was a great American
and true Patriot. the proceedings from yesterday at Alpine
N.J. site of the Alpine tower which he constructed, will be
rebroadcast on the web at 7PM, on June 14 & June 18 on
www.wfdu.fm.

I am still looking for an "S" meter for my SX-17.? I sent out the one I damaged for repair but I want to be prepared for a disappointing email telling me the meter cannot be repaired.? If anyone has one please let me know.

As a possible alternative, I am currently looking at an "S" meter for sale and the seller says it is from an S-40a.? The meter looks similar to the original SX-17 meter.? Does anyone know if the meter movement in the S-40a is the same one used in the SX-17?

A happy ending to this story, another ham with an SX-17 "S" meter,
needs the plastic scale from my defective "S" meter cause his is

The SX-17 I received the replacement "S" meter from was a junker so it

Locked HALLICRAFTERS 1000A

 

Need some help guys and girls:

Just bought a 1000a off ebay. The dial needed to be restrung. It was
picking up one station where it was stuck and it sounded really good
before restringing. This was on the regular AM band, not shortwave.
Anyway, I got it restrung and back together but now all I get is low
occational static. No sound at all. The tubes do not seem to light
either. It still has all the old caps and electrolytics. Does anyone
have any suggestions? Am I missing something obvious here? Why
wouldn't the tubes light up? Any help is appreciated.

That was really a dumb answer by me because it doesn't really matter
which radio you have. Although, if you have a SX-1000a, you have
gold.

Anyway, if the tubes are not lit, there could be a number of problems
as follows:

1) Filaments are in series and one has opened
2) If filaments are transformer supplied, transformer could be bad.
3) Bad solder joint

The best and easiest thing to do, is check the tubes and measure the
filament voltages and see if anything is there. If all the filaments
are out, it could be a simple fix. I am curious though how you are
getting static when all the filaments are out.

I am NOT familiar with this radio, and you haven't given a whole lot
to go on, but I think some very basic troubleshooting techniques are
in order.

Almost 40 years ago I worked for an old radioman who often shouted
"Mech First." What he meant was, "Look carefully for clues of a
mechanical nature before using a lot of test equipment to search for
subtle electronic things."

In your case, the suggestion to clean the tube sockets is a good idea
- a compromised socket often shows visible corrosion. Along the same
lines, work some contact cleaner through ALL of the switch contacts.
While you're doing this, make certain that their mechanisms operate
freely, with solid detents and clicks where you expect to find them.
The "background static" you describe may be indicative of something
like a band switch which has hung up half way between positions.

But considering your overall symptoms, I'd suggest you do something
very embarrassing: make sure ALL of the tubes are in their correct
sockets! I'm guessing that at least some were removed for the
re-stringing (and they SHOULD have been, to avoid damage from slipped
pliers, dropped screwdrivers, etc). When the tube types (5U4, 6BE6,
etc) are stamped on the chassis it is sometimes unclear which socket
the marking applies to. Not to mention that many of us have picked
up, say, a "12SK7" and parked it into a socket clearly marked "12SQ7".
Nothing, after all, is foolproof since we fools are very ingenious!
(And more than one of my co-workers has enjoyed his favorite malt
beverage at my expense after solemnly swearing to keep quiet about
something I had done . . . )

And if, by some miracle, a tube jumped into the wrong socket when you
weren't looking - there's a better than even chance that no
catastrophic damage was done. At least it's worth the effort to
correct the mis-placement and power up the radio.

My last suggestion is to look VERY carefully in the physical vicinity
of the re-stringing operation. Pay particular attention to the tuning
capacitors. Make sure that no bits of stray wire got lodged between
the movable plates of the capacitors, and that the plates are not
touching each other. Again, this doesn't really explain the lack of
filaments but it could account for what you hear.

Good luck with your project - keep us informed!

Thanks for the help everyone. Here's where I am now.
I took the tubes out and reseated them and the radio
works very well. The sound is really unbelievable.
However, when I switch bands the radio will drop all
sensitivity (act like it was before, totally deaf) but
will come back with a slight rap on the top back
portion of the case. Does this this narrow down any
possible problem areas or will a good cleaning with
contact cleaner do the trick? Does this indicate a
bad tube? Also, what is a good brand of contact
cleaner? Again, thanks for all the help.

Well, sounds like you found part of the problem. Glad it is
working. As to your question about a good cleaning, yes that is
exactly what it needs. Include in your cleaning all switches, pots
and any other moving electrical contacts.

These things take time and it also allows you to get to know the
inards of your radio. Since you pulled the tubes and reseated them,
I would follow the suggestion of others about cleaning the tube
sockets with a small dental brush and a contact cleaner. Do not
forget to clean the tube pins.

A good cleaner is one that does not melt plastic. The ones I use are
called "Pro-Gold" or something like that. Others can clue you in to
the exact name. Good luck, it sounds like you are almost there. It
just needs a little more TLC.

Well, sounds like you found part of the problem. Glad it is
working. As to your question about a good cleaning, yes that is
exactly what it needs. Include in your cleaning all switches, pots
and any other moving electrical contacts.

These things take time and it also allows you to get to know the
inards of your radio. Since you pulled the tubes and reseated
them,
I would follow the suggestion of others about cleaning the tube
sockets with a small dental brush and a contact cleaner. Do not
forget to clean the tube pins.

A good cleaner is one that does not melt plastic. The ones I use
are
called "Pro-Gold" or something like that. Others can clue you in
to
the exact name. Good luck, it sounds like you are almost there.
It
just needs a little more TLC.

Thanks for the help everyone. Here's where I am now.
I took the tubes out and reseated them and the radio
works very well. The sound is really unbelievable.
However, when I switch bands the radio will drop all
sensitivity (act like it was before, totally deaf) but
will come back with a slight rap on the top back
portion of the case. Does this this narrow down any
possible problem areas or will a good cleaning with
contact cleaner do the trick? Does this indicate a
bad tube? Also, what is a good brand of contact
cleaner? Again, thanks for all the help.

I am NOT familiar with this radio, and you haven't
given a whole lot
to go on, but I think some very basic
troubleshooting techniques are
in order.

Almost 40 years ago I worked for an old radioman who
often shouted
"Mech First." What he meant was, "Look carefully
for clues of a
mechanical nature before using a lot of test
equipment to search for
subtle electronic things."

In your case, the suggestion to clean the tube
sockets is a good idea
- a compromised socket often shows visible
corrosion. Along the same
lines, work some contact cleaner through ALL of the
switch contacts.
While you're doing this, make certain that their
mechanisms operate
freely, with solid detents and clicks where you
expect to find them.
The "background static" you describe may be
indicative of something
like a band switch which has hung up half way
between positions.

But considering your overall symptoms, I'd suggest
you do something
very embarrassing: make sure ALL of the tubes are in
their correct
sockets! I'm guessing that at least some were
removed for the
re-stringing (and they SHOULD have been, to avoid
damage from slipped
pliers, dropped screwdrivers, etc). When the tube
types (5U4, 6BE6,
etc) are stamped on the chassis it is sometimes
unclear which socket
the marking applies to. Not to mention that many of
us have picked
up, say, a "12SK7" and parked it into a socket
clearly marked "12SQ7".
Nothing, after all, is foolproof since we fools are
very ingenious!
(And more than one of my co-workers has enjoyed his
favorite malt
beverage at my expense after solemnly swearing to
keep quiet about
something I had done . . . )

And if, by some miracle, a tube jumped into the
wrong socket when you
weren't looking - there's a better than even chance
that no
catastrophic damage was done. At least it's worth
the effort to
correct the mis-placement and power up the radio.

My last suggestion is to look VERY carefully in the
physical vicinity
of the re-stringing operation. Pay particular
attention to the tuning
capacitors. Make sure that no bits of stray wire
got lodged between
the movable plates of the capacitors, and that the
plates are not
touching each other. Again, this doesn't really
explain the lack of
filaments but it could account for what you hear.

Good luck with your project - keep us informed!

Don...If the other fixes don't work...Try cleaning
the tube sockets
(both male and female). I use a good contact cleaner
and the little
wire brushes they make to clean between teeth
(available at many
supermarkets...near the toothbrushes). I've had
several radios just
stop working and it turned out to be a bad (dirty)
tube contact.

Good Luck
