Subject: [NJARC] question regarding long wire antennas
Message-ID: <CAOUs0uxHzmCtFTNn_nUU+vYAYrU7d2AtG4xWiETgBWgrAqH+OA@mail.gmail.com>

Hey Everyone!
I'm planning on stringing up a long wire antenna in my back yard for use
with my soon-to-be crystal set and for my Scott SLRM, mainly for broadcast
band DXing. I was able to score 150 feet of 14 AWG wire at Lowes at 7 cents
a foot because green was on clearance. I've got about a 110 foot straight
shot from the peak of my roof to a tree in the back of my yard. My question
is: Should I make use of all 150 feet and shoot off into an L shape across
the yard to another tree, or should I just stick with the straight 110 foot
wire? Like I said, my main goal is pulling in broadcast band stations.

Additional question: At the house end of my antenna, how to I both tie it
off on the insulator to mount it to my house and connect the conductor to
the feed coax down to my radio?

Future plans also include a tuned loop, but that's a project for another
decade.

Thanks for any advice!
Joe Giliberti

Joe -

I suggest that you use the left over length as the feedline coming into the
house and forget about coax. Unmatched coax can act like a big capacitor and
ground all your incoming RF substantially. Regards - Mike

Joe,

Mike is correct.? KISS = keep it simple, stupid!? You might also want to 
think about a lightning arrestor or grounding switch if the antenna is high.

While we are on the subject, Can someone "explain like I'm five" how the lightning arrestor works?


You run a long wire in your backyard, all the way up to your window.  The arrestor has two terminals.  One goes to the long wire, the other goes to a wire you ran to earth ground.


Then what?  How does the antenna go into the radio then?  Capacitive coupling? or do you wire it into one of the terminals?


I get that the idea is to put a path into ground as direct as possible if the long wire is struck, but if you ran the wire directly to the long wire terminal what's to stop it from going both to ground and to the set?  I'm guessing you don't connect it to ground either.  If you connect it to ground is the gap capactively coupled?


I'm sure this is relatively simple to many of you, but I'm not sure if I understand it correctly.

Hi Matt,
The lightning arrestor I have on my ham antenna works like the spark plugs on your car engine.
If you put enough current into it, it will short out over the gap to the ground side and ground out the source.
Lightning certainly has enough current to jump over the gap to ground --- So it works just like a spark plug.
I hope this helps.
See you at the next meeting...

Hate to be picky, but, it is the voltage and not the current the causes the
spark hence short. As Al pointed out, it is still recommended that the rig
is disconnected during those times. 73 - Mike

Matt,

The lead-in wire as well as the ground go to the radio.? The arrester, 
hopefully, shunts most of a lightning strike to ground outside the 
house.? Traditional arresters were typically simple air gaps, I'm 
guessing in the neighborhood of 0.01 inch.? Normally, the arrester is an 
open circuit.

For most of us, our antennas are lower than the nearby tree, buildings, 
and power lines, so the chance of a direct strike is minimal.? In this 
case, a simple arrester, and disconnecting the radios, especially solid 
state things is sufficient.

If your antenna is high and exposed, things get complicated.

The analogy to a spark plug is a good one.  However, maybe I am just a
wording junky but, if lightning strikes your antenna, the antenna is trashed
and so is the radio, TV or what have you.  The function of a (miss-named)
lightning arrestor is to bleed off static charges which can develop by wind,
rain, snow, etc. blowing or falling by the antenna.  The thinking, by some,
was that the charged antenna attracts lightning, maybe so maybe not, I am an
electrical engineer, not a meteorologist and more.  But, static charges and
sparks can and do wreck antenna coils in radios and more.

My first time, taking arrestors seriously was in the early 1950s as a kid
with a shortwave radio and antenna (Allied supplied an arrestor with the
antenna kit).  I was sitting in the living room and I kept hearing a snap
every few seconds.  After much searching for the cause, I found it.  The
night before we had experienced the beginning of a pretty wild storm (snow
storm - ice crystals and high wind).  Dad had disconnected the TV twin-lead
from the TV set and even unplugged it 'cause up front there had been a
couple of lightning flashes.  The snap was a static spark between the
exposed wires of the 300 ohm twin-lead of the TV antenna.  The next time at
the auto garage where dad worked I got to talk with the radio repairman
employed there.  He explained the definition of "snow static".  I went home
and installed the arrestor with a good ground!

Hi Gerry,
I'm not an electrical engineer like yourself, but my experience of the 
extent of the spark arrestor's capabilities went a little further.
I am a software engineer and my knowledge of the subject comes only from my 
limited experience.
My antenna took a direct strike from a HUGE bolt of lightning, according to 
my neighbor who saw it happen. It felt like a truck hit my house!
The antenna is mounted on a 25 foot aluminum flagpole mounted at the top of 
the gable of my house and is the highest object in the area at 48 feet high.
So I guess it's a prime target for a lightning strike!
Somehow the spark arrestor saved it as well as the radio, even though the 
radio was connected to the antenna at the time.
The antenna was not trashed and the radio was still intact. Go figure??? I 
would think it should have all been burnt to a crisp.
I only had damage to the spark arrester itself! After changing it out for a 
new one, I found, to my surprise, everything still works fine???
I guess I just got a really good spark arrestor - - - or I was really lucky!
I attached a picture of the spark arrestor I had (and replaced it with), in 
case anyone one would like to get the same one for their antenna.
Now days, I keep a spare in the shop - lol

Lightning Current
Williams says that a typical lightning bolt may transfer 1020 electrons in a
fraction of a second, developing a peak current of up to 10 kiloamperes. 
According to Uman, the German scientist Pockels discovered that basalt rock
in the vicinity of lightning strikes was magnetized and deduced currents on
the order of 10,000 amps in 1897. Ampere's law allows you to deduce the
current in a wire from the measurement of the magnetic field at some radius
from the wire. Pockels presumably had measured the magnetizing effects of
large currents on basalt and was able to scale those experiments to estimate
the current associated with the lightning. Based on that principle, magnetic
links are widely used for the measurement of the lightning currents. Most
measurements have been in the range 5,000 to 20,000 amps but a famous strike
just before the Apollo 15 launch in 1971 was measured at 100,000 amperes by
magnetic links attached to the umbilical tower. Currents over 200,000 amps
have been reported. 
One could envision a magnetic detector based on both Ampere's law and
Faraday's law which could give you an estimate of lightning current provided
you had a measurement of the distance from the detector to the lightning
strike point. If you set up a coil of wire in a vertical plane, then the
rate of change of magnetic field through the coil would generate a voltage.
If you could sum (integrate) the current generated by that voltage, you
could calculate the charge transferred in the lightning strike. With several
such detectors in an area, you could model the location as well as the
charge associated with the strike. 
Most commonly, the lightning current ceases in about a millisecond for a
given stroke, but sometimes there is a continuing current on the order of
100 amps following one or more of the strokes. This is called "hot
lightning" and it is the cause of lightning fires according to Uman. The
temperatures of lightning are 15,000-60,000?F for both "cold" and "hot"
lightning - it is the continuing current that starts some 10,000 fires per
year in the U.S. in the estimation of Uman.

The above is both in one of my text books and at one time I also found it
online.

I am an electric utility engineer and have worked in EHV electric
transmission design and in utility operations.  When lightning strikes
hardware on poles or houses in electric distribution, it usually rips the
conductors to pieces or at least rips it loose from its mountings on the
poles or buildings, leaving a charred track where the cables had been.
Utilities employ expulsion arrestors (which operate differently than gap
static arrestors) to protect such facilities and they do some of the time.
However, let's think about even #10 or #12 wire in the face of the amperages
involved.  These conductors don't stand a chance with that kind of energy,
even for milliseconds.

I did experience one case out on the farm where I had a radio and an antenna
which was hit with a strike.  I had previously lost a couple of antenna
coils in radios and was unable to explain that the radio that experienced
the hit was OK after the strike.  I am guessing that the strike was at the
windmill end (175 feet away) and the antenna wire simply melted or vaporized
before the currents could travel the length of the antenna to the radio.

The one thing of which I am certain, however, is that in 45 years in the
utility business, I have run across many, many unexplainable incidents
involving lightning.  The most fun to watch was seeing a lightning strike to
ground where the lightning actually crawled along the surface of the ground
for a couple hundred feet before it disappeared into the ground.  I was
sitting on a tractor about 1/8 mile away at about age 16.

I am not familiar with the unit you pictured.  The arrestors I used were the
old porcelain gap type from Allied, BA, McGee and others back in the 1960s.
However just from the physical size, these units are not dealing with the
currents of the scale of lightning strikes.

Thanks guys for all the helpful tips and tricks.
My only concern with using the remaining antenna wire as the lead lead wire
down to the radio down in the basement is interference. Between ballasts is
LED light bulbs, WiFi signils and cordless phones, I was worried about
stray signals making their way into my receiver. Now I know that my WiFi
and phones are in the GigaHertz range, but I'm sure that there are outer
household sources of interference.

Between this and the tuned loop I hope to build with my Scott SLRM, I hope
to finally be able to enter next year's DXpedition and maybe, just maybe,
be competitive.

Thanks again!
Joe

Below is a link to Dropbox with pictures of the 2017 conference.

Dropbox link: 
https://www.dropbox.com/sh/tr8otfvys9g9jc8/AABeuV4zOxGRkr8u-ffNLRMIa?dl=0

Two of the major attractions are a Zenith Stratosphere console and the 
Delano, CA Voice of America transmitter.? The transmitter was acquired 
in 2014.? This was the last operating VOA transmitter, shut down in 2007.

There is a "Links" folder included with the pictures, that includes 2 
links relating to the transmitter.? I also included a link to pictures 
that I took in 2014 of the arrival of the transmitter.

Also, in the Banquet link you'll notice a fourth person sitting with 
Dave, Jon and me.? His name is Abdulkhaleq Alqadhi, or Abd as he likes 
to be called, from Kurdistan.? It was his first time attending the 
conference.? He has a small collection of table radios, common in his 
area, but really rare here.? He was also impressed by the NJARC website, 
and really wanted to visit, but didn't have enough time.? He and I have 
been corresponding, and I'm going to try and help him obtain parts, 
difficult in his country.
/
/It was great meeting someone from another culture with the same 
interest(s).? Hopefully he'll be able to visit the U.S. again someday 
and visit New Jersey and OUR museum.

Joe,

Using a shielded feed line can be helpful to control local noise.? I 
gets a little complicated, but it's not rocket science.? Broad-band 
transformers make this practical.

See:? http://www.skywaves.ar88.net/ANTENNA/antsys.htm

I can't believe how long ago I did this.? It might be time to reveal the 
secrets of the balanced/unbalanced? doublet we're using at the Museum, 
but that's center-fed and might present some physical challenges 
depending how you hang it..

The UV light does work sometimes.? Picked up a small UV flashlight and 
keep it on the bench.? Gently rubbing the tube in your hair sometimes 
helps also, due to the oils. However I now have less "real estate" in 
which to do this.

Reference my 1932 RCA Radio/Phonograph console Model RE-18.
The radio has been successfully repaired and plays fine.  The phonograph is a single play 78 rpm
player.  The problem is that the magnetic phonographic pick-up (unknown part number) does not function.
Therefore I?m looking for a replacement or to have the pick-up repaired.
Hope someone can help.
Thanks.

Subject: [NEARC_Radio] restored 1937 Wurlitzer juke box [5 Attachments]



  
    
                  

I love these old radios we collect and restore, but Bruce's Wurlitzer 1100 inspired me to want a juke box.  Got the "bug" one Saturday aternoon, went looking on Craig's List, and by midnight I was back home with a 1939 Seeburg from RI.  Then a month later a 1946 Seeburg "trashcan" from eastern CT.  Seems I got the bug at right time, because those seem to be the only 78 machines in all of NE for over a year. The later 45 machines are abundant, but their plastic and chrome doesn't do anything for me--prefer the light up "woodies" of 30's and 40's and I have several thousand 78's for fodder.  The Seeburgs sound great and were very reliable, but you can't see the works without lifting lid.  What really captured my fancy right from the getgo was Wurlitzers with their picture window into the action.  Finally found one cheap, and drove over and got it f rom other side of Rochester, NY beginning of June.  Solid cabinet, but atrocious looking:  someone had "modernized" it with a yellow paint job and leather trim.  Most of the 30's Wurlys were just beautiful cabinets with no light-up plastics, but a few special models had that added, and this 616a from 1937 was one.  Re-wired all the cabinet lighting, stripped finish then stained and put on about ten coats of clear lacquer.  Re-capped the amp, which puts out great sound with the quad 45's.  Tube lineup: 30,30,45,45,45,45,5Z3.  Howie suggested I share this with you folks, so attached are some "before" and "after" pics and link toYoutube  video my son shot yesterday with his Iphone.

Subject: [NJARC] AK 80 question
Message-ID: <2d2386d8.e30ba.15e68ca269f.Webtop.39@optonline.net>

Just restored an AK 80.  After replacing all the caps, noisy resistors, 
two bad tubes, most of the rubber wiring that had most of the insulation 
gone, it actually works.


My question is about the "volume control" (see schematic): It's in the 
cathode circuit of the oscillator, so when it's adjusted, it sounds 
almost like a regeneration control, oscillating, etc..  It also looks 
like the schematic is wrong.  It shows the cathode grounded, which would 
negate any effect of adjusting the control.  It's not grounded in this 
set.  The radio is basically untouched, except for two electrolytic caps 
already replaced.


Thanks, Bill

Bill,

Well, this is pretty disturbing.? Clearly there are errors in the 
documentation, and maybe the original wiring.? Can you say FUBAR?

I'd disconnect the oscillator cathode from the rest of the circuit, and 
ground it.? The slider on the volume control raises the cathodes of the 
!st Det and IF above ground, while their grids are at ground for DC.? 
this should, indeed, effect RF/IF gain control:? more cathode voltage = 
less gain.? BTW, 35's are remote-cutoff tetrodes, so they're intended 
for this sort of operation.

The alternative would be to leave the oscillator cathode connected to 
the volume control, and clear any ground on that circuit node.

Good luck,
Al

Hello, I would imagine by now you will have received the news about Gary. I apologize up front as these last 13 days were at times more than we could handle. There were days when things were changing by the hour. Needless to say my main focus was that of Gary and are family. So I hope each of you will forgive me for lack of texts, emails etc.

Sadly, Gary passed away shortly after 6am this morning with complications following his emergency open heart surgery on Sunday, 8/27. 

Following his cremation, a private burial will be held for just his immediate family.

We are holding a memorial service for him and ask that you join us at this time to honor his life.

Tried Al's idea (grounding the cathode), and do I seem to get more gain 
(volume), thanks Al.?
However, there is slight audio distortion (this way and with the
original wiring).? Happens on strong and weak stations, long and short 
antenna.



Cleared the audio stage, the audio is distorted from the IF going into 
the 2d
detector.? Confirmed with a demod probe and signal tracer.? What would
cause audio distortion out of the IF?? Tried changing the IF tube, no
change.? It's not really that severe, just want it as perfect as 
possible before giving it back


Thanks, Bill

       My question is about the "volume control" (see schematic): It's 
in
       the cathode circuit of the oscillator, so when it's adjusted, it
       sounds almost like a regeneration control, oscillating, etc..? It
       also looks like the schematic is wrong.? It shows the cathode
       grounded, which would negate any effect of adjusting the 
control.?
       It's not grounded in this set.? The radio is basically untouched,
       except for two electrolytic caps already replaced.






       Thanks, Bill

Forgot to add - was able to do an IF (130 KHz) and RF alignment.

Tried Al's idea (grounding the cathode), and do I seem to get more gain 
(volume), thanks Al.?
However, there is slight audio distortion (this way and with the
original wiring).? Happens on strong and weak stations, long and short 
antenna.



Cleared the audio stage, the audio is distorted from the IF going into 
the 2d
detector.? Confirmed with a demod probe and signal tracer.? What would
cause audio distortion out of the IF?? Tried changing the IF tube, no
change.? It's not really that severe, just want it as perfect as 
possible before giving it back


Thanks, Bill

     Bill,



     Well, this is pretty disturbing.? Clearly there are errors in the
     documentation, and maybe the original wiring.? Can you say FUBAR?



     I'd disconnect the oscillator cathode from the rest of the circuit,
     and ground it.? The slider on the volume control raises the 
cathodes
     of the !st Det and IF above ground, while their grids are at ground
     for DC.? this should, indeed, effect RF/IF gain control:? more
     cathode voltage = less gain.? BTW, 35's are remote-cutoff tetrodes,
     so they're intended for this sort of operation.



     The alternative would be to leave the oscillator cathode connected
     to the volume control, and clear any ground on that circuit node.



     Good luck,

     Al

I would check the voltage on grids of all the tubes to make sure none are
positive. This could be caused leaky coupling capacitor which would indeed
cause distortion. Regards - Mike

This is an early superhet with a very narrow IF, so I was thinking that 
this may be normal(?).

Yes, I know it is a superhet as that is evident from the schematic. Besides, I have one myself that is distortion free. 73 - Mike

Bill,

Does the distortion decrease with decreased "volume" (that's actually RF 
gain) or weaker input signals?? Stick your ear right in the speaker.

Scope the IF plate looking for clipping.? There a balancing act here 
between the gain of the 1st detector / IF and the 2nd detector /audio 
out tubes.

You might check that the latter are working properly.? If you don't have 
enough audio gain, then you're going to run the RF/IF into distortion 
before the 3nd detector.

Also, is the oscillator running well?? Check that the grid resistor is 
really 100K.? There should be quite a few negative volts on the grid 
when measured with a hi-Z meter.

Good luck,
Al

Bill,

I'd expect that to roll off the highs, and make it sound muffled, but 
not distorted as in scratchy.

You could try stagger tuning the IF a bit.

Max,

Wow, I didn't know that such a base existed.


That's from the the EF41data sheet.

Anybody have any ideas?

The "distortion" is constant, at all volume levels, and signal levels.


Fed modulated signal from my RF generator, see attached scope traces.? 
Very low signal at the IF plate, additionally my 'scope loaded it down.


The oscillator grid resistor measures 103K, and the voltage is -7 
relative to the cathode.


Looking at the trace, it's not really that distorted.? A tempest in a 
teapot??

     Bill,



     Does the distortion decrease with decreased "volume" (that's
     actually RF gain) or weaker input signals?? Stick your ear right in
     the speaker.



     Scope the IF plate looking for clipping.? There a balancing act 
here
     between the gain of the 1st detector / IF and the 2nd detector
     /audio out tubes.



     You might check that the latter are working properly.? If you don't
     have enough audio gain, then you're going to run the RF/IF into
     distortion before the 3nd detector.



     Also, is the oscillator running well?? Check that the grid resistor
     is really 100K.? There should be quite a few negative volts on the
     grid when measured with a hi-Z meter.



     Good luck,

     Al

Tried Al's idea (grounding the

         However, there is slight audio distortion (this way and with 
the
         original wiring).? Happens on strong and weak stations, long 
and
         short antenna.



         Cleared the audio stage, the audio is distorted from the IF
         going into the 2d detector.? Confirmed with a demod probe and
         signal tracer.? What would cause audio distortion out of the
         IF?? Tried changing the IF tube, no change.? It's not really
         that severe, just want it as perfect as possible before giving
         it back

            Bill,



           Well, this is pretty disturbing.? Clearly there are errors in
           the documentation, and maybe the original wiring.? Can you 
say
           FUBAR?



           I'd disconnect the oscillator cathode from the rest of the
           circuit, and ground it.? The slider on the volume control
           raises the cathodes of the !st Det and IF above ground, while
           their grids are at ground for DC.? this should, indeed, 
effect
           RF/IF gain control:? more cathode voltage = less gain.? BTW,
           35's are remote-cutoff tetrodes, so they're intended for this
           sort of operation.



           The alternative would be to leave the oscillator cathode
           connected to the volume control, and clear any ground on that
           circuit node.



           Good luck,

           Al

             Just restored an AK 80.? After replacing all the caps, 
noisy
             resistors, two bad tubes, most of the rubber wiring that 
had
             most of the insulation gone, it actually works.





             My question is about the "volume control" (see schematic):
             It's in the cathode circuit of the oscillator, so when it's
             adjusted, it sounds almost like a regeneration control,
             oscillating, etc..? It also looks like the schematic is
             wrong.? It shows the cathode grounded, which would negate
             any effect of adjusting the control.? It's not grounded in
             this set.? The radio is basically untouched, except for two
             electrolytic caps already replaced.





             Thanks, Bill

 From Wikipedia:
Rimlock baseThe Rimlock
  (B8A) base is an 8-pin design with a pin circle diameter close to
noval, and uses a nub on the side of the envelope to engage with a guide
  and retaining spring in the socket wall. This provides pin 
registration
  (since the pins are equi-spaced) and also a fair degree of retention.
Early tubes with this base type typically had a metal skirt around the
lower ~15mm of the envelope to match the socket wall, and this offered a
  degree of built-in screening, but these were fairly soon replaced by
'skirtless' versions which had a characteristic widening in the glass to
  compensate physically for the absence of the skirt. In the European
naming scheme, rimlock tubes are numbered in the ranges 40-49, 110-119
(with exceptions), and 400-499, e.g. EF40. Although virtually unknown
elsewhere, this was a very common base type in European radios of the
late 1940s through the 1950s, but was eventually displaced by the
ubiquitous B7G and noval (B9A) base types.

Leave it to Bruce to find one of these rare gems!  Tom did the electronics and I did the cabinet. Photo attached.

Had to take a break from my AK and fix my broken email, down for 5 days.

Haven't been able to send emails from any mail client, Thunderbird, 
Outlook, iPad/iPhone.? Received emails OK, and could send via web mail, 
and normal internet worked.

I reset the modem (removed/applied power), and router to no avail. 
Finally caved and called Cablevision.? After dealing with 3 Darwin Award 
candidates, disconnects (convenient), 48 hour callbacks that never 
happened, I finally called back today and actually got an intelligent, 
eloquent technician.? Knowing that I was pissed, he was extremely 
patient, and in a moment of divine intervention he suggested by-passing 
the router.? Well everything was fine going directly through the modem.? 
He suggested replacing the modem as it was 10 years old (didn't know 
they wore out).

Instead I did a hard reset, using the reset button.? Went through the 
setup process, and all is now good.? Just think, 5 days and all I had to 
do was press a damn button!? DUH!? (Before the reset, I went through all 
the settings, firewall, encryption, etc., and everything was correct)

Can't explain why the router passed everything except mail clients, but 
it's just one of those mysteries without an answer.? Now, where are all 
my lost socks??

Just wanted to share.

Many cable networks upgraded their networks and turned off support for earlier modems. 

I have a friend out West whose cable fried her modem with their new signal. When she returned the modem to get a new one, they confessed their action--but still charged her for a new one. 

My advice for any computer issues that MAY be the fault of the cable company is to always try the reset buttons or just put the issue to Google. 

The other day a neighbor spent a few hours on the phone with a Verizon rep for a cell phone issue--with them finally giving up and opening a repair work order. I just put the question to Google and had it fixed in a few minutes. 

Best wishes. 
Bob

By the way, Darwin awards ignore people who are that way because their company failed to train them to listen to the customer first before going through their troubleshooting list.

Tried the Google route.? I was receiving a generic error code (5.7.1), 
the only close reference found in a Google search was about a email 
containing a signature was tagged as spam.

My error message:

Apparently it was being generated by my router!

Some of you may have seen the Hagley Library's press release on Monday
about the opening of the David Sarnoff Library Collection, but you may be
surprised to learn that the Hagley has another collection of digitized
material donated by collector John Okolowicz:
http://digital.hagley.org/islandora/object/islandora%3A2301532. It includes
hi-res PDFs of 15, count'em 15, of RCA Radiotron's dealer magazine from
1930 and 1931: http://bit.ly/2f81Rog. Ray was kind enough to loan two or
three copies from 1932 that I scanned at the DSL, so the Hagley probably
the most complete set of this publication.

best, Alex

I saw this on the BBC News App and thought you should see it:

Canada?s vital role in the communications revolution

Guglielmo Marconi was instantly a name known around the world, comparable today perhaps to Mark Zuckerberg or Steve Jobs.

Hello to the Boys and Girls of the NJARC -

                          Well, it?s that time where many folks flock to Kutztown Pennsylvania with their goodies to buy and sell. I have good news - The weather was warm and fall like, and there were many vendors and buyers. If you were there to see this for yourself or maybe you not make it, I have recorded a 14 minute condensed video including Friday goings on, the Friday night auction, and Saturday! So grab your popcorn and your favorite beverage and enjoy. Click on the link below.

Found this radio for sale near me, anyone ever heard of the manufacturer?
It didn't come up in my McMahnon Radio Collectors Guide.

The front seems a bit beat up and possibly missing knobs, and I'm pretty
sure those batteries are toast :)

Nothing came up in Greg Hunolt's "Battery Set Compendium" from 2014, or 
radiomuseum.org.

Does the label say where it was made?

Kind of a mystery.  Steve R. indicated they were making radio cabinets in
1924.  Your pictures pretty much indicate that it is "home brew" while
cabinet label says New Brunswick, NJ.  Sometimes early constructors
cannibalized an existing set to create their own radio ideas.  Still like
those batteries.  Is the price a secret?

Dogbones were body/end/dot (BED)

I assume these were the same, except the dot is a stripe in the middle

Bill,


I was trying to figure out how to read a 4 stripe resistor  that looked like that in the tv I was restoring a few weeks ago.  They didn't measure up to what the colors would have been.  None of the other resistors were 4 stripes and I couldn't find them on the schematic.  Turns out they were chokes\coils.


Food for thought.


Matt

Fortunately these were resistors and match this color code sequence.? 
Even thought most were way off, a few were close enough to confirm I had 
discovered the right sequence.

Now....the paper caps with odd labeling.? Will do some Googling, and 
post something here if I don't come up with a solution.? Stay tuned.

The one on the right is a 1 meg, and the one to the left is 520k, Or use a ohm meter.

I've been trying to organize my tube stash, and have a severe lack of
loctal boxes, plus some larger and some smaller.

Has anyone come up with a good way to store them in an organized fashion?
I've seen what I think are old test tube boxes being used by the club for
mini tubes, so I was thinking something like that.

I've taken to using zippered plastic sandwich bags to store many of my
parts lately. "Pourable" tubes can still be stored in large corrugated
cardboard cartons, sorted as you prefer (by type, by filament voltage or by
individual tube number) into bags. Not anywhere near as organized as using
partitioned cartons or individually labeled tube boxes, but hey, it's not
like you're looking through them every day. Plastic bags also work great to
store 78 RPM records after you've cleaned them and discarded their
deteriorated paper sleeves.

ago. The object is

to encourage restoration, operation and enjoyment of this older Classic 

equipment.



However, you need not operate a Classic rig to participate in the CX. 

YOU MAY USE ANY RIG in the contest although new gear is a distinct 

scoring disadvantage.

You can still work the "great ones" with modern equipment.



There are new Bonus Scores for using the same model rigs as your Novice 

station and for using an RME receiver and for using a WRL transmitter.



Awards will be given in two classes: 1. Three or fewer 

receiver-transmitter pairs 2. Four or more receiver-transmitter pairs.

I repaired Dawson's RCA 60's console at the last clinic and now he needs 
help with his record changer.? Can anyone give him a hand?

He lives a little south of here, I think near Cherry Hill or in that area.

Thanks, Bill

Hey Bill,

Can you put me in touch with your clubs phono/RCA guru. I have the 
record changer (RP-218-12) about 90% together and just need a little 
help getting a tone arm problem ironed out.

Also, I wanted to let you know that my wife and I will be moving soon. 
She finished her graduate nursing degree and accepted an amazing 
position in Seattle. We're pulling up stakes at the end of October. 
Can't thank you enough for your help.

Thanks
Dawson

The Pavek Museum, a broadcast history museum in the Twin Cities area, 
recently underwent a major renovation for several months. Work was done

Hello!

I have very recently become the proud owner of a 1956 Pontiac Chieftain. As
I've been poking around fixing things I looked the radio over. I
disassembled and cleaned the vibrator but saw that there is a tube missing.
Can anyone point me towards a schematic? It's a Delco radio, push-button
but not Wonderbar. It has one chassis with the controls and faceplate and
another with the power supply and speaker, but I have not yet found the
model number.

Thanks!

Jeremiah

Found an on-line service manual telling how to remove the radio and 
access the tubes but no further information.

http://www.pontiacsafari.com/L1EarlyV8Pontiacs/56ShopManual/1956_shop_manual.html

Usually the tube layout is in the cover accessing the tubes.

The 'new' capacitor codes always manage to flummox me too.

A Google search reveals the secret:
http://kiloohm.info/3-digit-capacitor/164

The "j" apparently means that it is a 5% tolerance.

.16uf 5% tolerance. As far as voltage, if there are no other markings on the capacitor, your guess is as good as mine.
