Dave, interesting video.
My first professional position after college was at RCA Labs in the early 1980's. ?There was only one gentleman still working on next generation CRT electron guns at that time. ?He was in the main building basement not far from the Sarnoff Library. ?He build CRT electron gun assemblies using the same style glass lathe shown in the video and tested them in an adjacent room where there were also a?couple of resistance welders used for gun assembly.
Next to his test setup was a 55 gallon barrel full of the guns he had made and tested over the years. ?So he fabricated, built, tested and discarded his handiwork on a monthly basis, ?Truly a one man show!
When I returned to Princeton in the early 1990's, RCA Labs had been replaced by the Sarnoff Corporation and the lone CRT worker had evidently retired, but the lathe, welders and test set were still there, IIRC.
The enclosed photo is of two CRT electron gun examples from that barrel. ?Sorry about the shadows, if there is any interest, I can probably do a better job on the photo when the sun is out.Jim

Hi

I saw that Marv put some info on Edison's Kinetophones in the new issue of the Broadcaster. I thought you might also want to read my column in the November issue of Classic Images magazine on the topic as well. I have attached a PDF of the article. I hope you enjoy it and, if possible, catch George Willeman's presentation at MOMA. 

Best wishes.

That's a great story--is there any way to share it publicly? I'd be happy
to tweet a link to accounts related to Edison, motion pictures, and media

Hi All,
I have a Zenith  6-S-229 cabinet that I brought off eBay years ago.  The
cabinet is missing the bottom left base (which was not shown in the
pictures of course).  I have don't have a router nor the skills to

Meant to be there, but got mixed up on the date.  Even though you 
stressed the date many times, shown in the Broadcaster many times and 
marked on the calendar, I still thought it was tomorrow.  I was getting 
ready to load the truck around 11 this morning when my wife questioned 
me.  Maybe I should look at the calendar more often?   :-[

Greetings Fellow Enthusiasts...I want to thank all participants at today's Fall Swap Meet for their patience with the late "opener" of the PAL facility.? I was told the cause was due to illness by the Properties & Facilities manager.? Everyone pitched in to lend a hand, and put the swap meet back on schedule....and as a result, it was a great success.? A special shout-out goes to Len Newman for helping with the canteen and front entrance table!See you all at the Nov. 11th meeting at InFo Age.....Richard Lee Pres. NJARC

I've heard the variac trick for forming caps too, and I've heard both sides of the story, and being fairly green when it comes to electronics repair, I'm not qualified to offer much of an opinion on this particular point.


I did want to mention that at one of the repair clinics at the suggestion of one of the experts we used a variac to troubleshoot a short that was blowing out tubes in a series string TV (a Pilot TV in this case).  Every time I would plug the set in, I'd blow a filament, and then once the string was broken, you couldn't measure anything.  By using the variac to "halve" the input voltage, it was enough to adjust the voltage chart, do measurements, and find where the issue was without losing more tubes.


I'm sure there is more than one way to troubleshoot issues like this, but it worked out well, and I thought it was worth mentioning.


Regards,


Matt

Jim,

I have, I admit, occasionally (mostly years ago) "plugged it in to see if
it works."  And yes, occasionally, it worked.  I have (again, last time was
years ago) brought it up slowly.  And yes, sometimes that worked too, but I
suspect they might have worked anyway if I had merely plugged them in.

Smarter people than me have since advised me that the only way to do this
intelligently is to bring up the B+ under controlled circumstances with a
lab power supply while monitoring current through the filter cap.  As you
know better than I do, there are leakage parameters to stay within while
raising the voltage.  At some point it becomes a pass/fail situation,
backed by data instead of misplaced hope in aged, deteriorated parts.

So even though it occasionally "worked" I no longer have faith in the
'bring it up slowly on a Variac' method.  And for the modest price of a
couple of replacement electrolytic caps, I no longer bother to make the
meticulous, controlled/measured test.  And I (usually) no longer do the
'cross my fingers and hope that it won't blow up' thing either.

Subject: [NJARC] Bring it up slow on the VARIAC
Message-ID: <849f1c.3f3efaff.45521767@aol.com>

The Variac is a nice tool to slowly bring up voltage on a set.. This alone  
does not equate to the electrolytic capacitors being slowly brought up to  
voltage. It also does not tell you much, about current draw. To start with, 
you  want an ammeter on the load. The only Variacs that I have seen , that 
have this  feature built in, are the Eico and the Sencore.  Even if we add an 
 ammeter  in series with the load, it does not tell you what the capacitors 
 are doing. Obviously if an 8 tube set, is beginning to pull 4 amps, we 
have an  issue, but something that drastic is not usually the case. Also, bear 
in mind  that because of the warm up characteristics of rectifier tubes, the 
filter  caps may not see voltage until it is high enough to damage them 
without  reform. If you choose to re from the electrolytics, I suggest using a 
bench  B+ supply, capable of reaching working voltage, along with a digital  
multimeter to monitor the current draw of the capacitor being re-formed. In 
my  experience, a healthy cap, (in the 5-60 mfd range) after re form,  
should NEVER pull more than 3 or 4 ma. You slowly bring up the bench  supply, 
across the cap, with the meter in series, and watch the current, you  will see 
it spike, then begin to fall. each time it falls below 4 ma, raise it  
again, say 60 volts at a time, but never let the cap pull more than 50 ma. When  
they pull huge amounts of current, is when they destroy themselves. Better  
still. Eico  and Heathkit, and others made capacitance bridges, with built  
in power supplies. These are very lightweight supplies, only capable of  
supplying a few MA.. They are IDEAL and rather foolproof for re-forming, Their 
 lack of available current, prevents them from damaging the capacitor, and 
you  can simply hook them up, and let the cap sit for 20 min. or however 
long it  takes. Again, I place the MA meter in series, and watch the current 
fall. IF you  find an electrolytic will not stop leaking current, within a 
reasonable amount  of time, I say toss it. It is simply not worth the risk. 
Also... I make it a  policy to re check current draw a day or 2 after reform. 
If the capacitor does  not act like a  new capacitor (or at least close) and 
takes an extended  period of time to stop pulling current, again.. toss it. 
I have seen too many  "re-formed" capacitors fail suddenly and take a power 
transformer or costly  rectifier tube (or both) with them.  We are reaching 
a point where this  stuff is OLD.. I am finding more and more electrolytic 
capacitors , particularly  those from the 1950s and before , that are 
reaching the end of their useful  life. 15 or 20 years ago, these capacitors seemed 
much more willing to re-form  and and stay formed. From what I have been 
able to tell, capacitor technology  changed vastly in the 1960s, and hence 
electrolytic capacitors made from that  point and later, seem to fair better, 
and they are also newer. Also Sprague,  Mallory ,Astron and a few other 
electrolytic  capacitors seem to survive  vastly better than some other brands.  
Just my 10 cents on all  this...  Used to be 2, but we can calculate for 
inflation...

Subject: [NJARC] Bring it up slow on the VARIAC

Don't have the time to babysit an electrolytic capacitor while it reforms. ?Much easier to make up a little power supply with a large value resistor to limit short circuit current to 10 mA or so. ?Just hook up the cap, turn on the power supply and occasionally monitor the voltage across the cap with your trusty DVM while you do something else like cleaning the chassis or cabinet. ?
If the cap will reform, the terminal voltage will rise to the approximate open circuit voltage of the power supply. ?If it doesn't, then no harm is done since the maximum current that the power supply can charge the capacitor with is limited to well below what would cause heating in the capacitor.
I only bother to do this with canned electrolytic capacitors in higher end equipment. ?Cost conscious consumer radios and the like use cheap wax covered capacitors which never seem to reform to the point where they have a low leakage current so I just replace these outright, just like Dave mentioned. ?This is usually done with the cap needing reforming disconnected from the rest of set.
Once the cap is reformed and put back in the circuit, the reforming power supply does double duty by powering the set and I can then check non-electrolytic bypass and decoupling capacitors. ?Any leakage in these capacitors is easily found with simple voltage measurements and the leaky capacitor is then replaced. ?This makes quick work in finding those leaky screen bypass capacitors.Jim

 Subject: Re: [NJARC] Bring it up slow on the VARIAC
   
 The Variac is a nice tool to slowly bring up voltage on a set.. This alone does not equate to the electrolytic capacitors being slowly brought up to voltage. It also does not tell you much, about current draw. To start with, you want an ammeter on the load. The only Variacs that I have seen , that have this feature built in, are the Eico and the Sencore.? Even if we add an ammeter? in series with the load, it does not tell you what the capacitors are doing. Obviously if an 8 tube set, is beginning to pull 4 amps, we have an issue, but something that drastic is not usually the case. Also, bear in mind that because of the warm up characteristics of?rectifier tubes, the filter caps may not see?voltage until it is high enough to damage them without reform. If you choose to re from the?electrolytics, I suggest using a bench B+ supply, capable of reaching working?voltage, along with a?digital multimeter to monitor the current draw of the capacitor being re-formed. In my experience, a healthy cap, (in the?5-60 mfd range)?after re form, should NEVER pull more than 3 or 4 ma.?You slowly bring up the bench supply, across the cap, with the meter in series, and watch the current, you will see it spike, then begin to fall. each time it falls below 4 ma, raise it again, say 60 volts at a time, but never let the cap pull more than 50 ma.

Greetings!
One piece of equipment I am lacking in my collection is a variable transformer. If someone has a spare that they would be willing to part with, let me know off list and maybe we can hash out a deal on Friday. I figure I need at least a 5 amp unit.Thanks!

Well?..
             This may be a good moment to provide a giggle to all of you. Although I probably have nearly 1000 tubes, I need a 6DL5/EL95 - Pentode. I would gladly pay cash for this bottle! So if you could please check your domestic tube lair and see if this in your collection. Remember I can easily help you in your future tube endeavors!

Hello All!

I was wondering if anyone in the club would be masochistic enough to
tutor me a bit with regard to radio repair. I've been a member of the
club for nearly five years and, while I can test tubes and replace
capacitors, I know very little about how the circuits function nor do
I know much regarding diagnosis and troubleshooting.
So, would anyone in this wonderful community be willing to share their
knowledge with a youngin like myself?

Have a good night!

Hi Joe

I'd like to take your request and turn it into a suggestion. I also belong to a car club which periodically holds technical workshops. Perhaps one of our more experienced members can schedule something similar for all of us on the subject of radio repair. I would love to join such a meeting to learn more about the subject. How else can the knowledge be passed along to us newbies. I've only been a member two years. 

Thanks in advance.

There is a book titled "The Vacuum Tube Shortwave Radio" at:?http://www.richardmcwhorter.com/vacuumtuberadio/?which seems to cover the basics. ?This pdf is 212 pages long and covers theory, repair, alignment and even the re-stuffing of can electrolytic capacitors. ?It is password protected but the password is prominently displayed on the download page. ?So those who want to can save the text on their PC and start the ball rolling.
The perfect text has yet to be written but this is available now and it is free. ?An informal course can be taught using this text as a starting point using an email reflector format just like this club reflector. ?The only difference is that reflector would be just one ongoing topic on radio repair, circuit theory and "hints and kinks."
Anyone who is interested could join the reflector, this includes both newbies and those with years of experience. ?There doesn't need to be a formal instructor, we can just go through the text chapter by chapter and any questions can be posted and multiple answers shared. ?
I for one have never been to an NJARC repair clinic since I live so far away but I would think that the experienced repair people all have methods and short cuts not covered in the above text but are none the less valid and worth sharing within the group.
Thoughts?Jim

to teach it (paging Mr. Klase) I volunteer to organize it.

Here is a site with a downloadable version of "Elements of Radio Servicing." This is the book that many of us cut our teeth on. It's excellent.

There is a book titled "The Vacuum Tube Shortwave Radio" at:?http://www. richardmcwhorter.com/ vacuumtuberadio/?which seems to cover the basics.? This pdf is 212 pages long and covers theory, repair, alignment and even the re-stuffing of can electrolytic capacitors.? It is password protected but the password is prominently displayed on the download page.? So those who want to can save the text on their PC and start the ball rolling.
The perfect text has yet to be written but this is available now and it is free.? An informal course can be taught using this text as a starting point using an email reflector format just like this club reflector.? The only difference is that reflector would be just one ongoing topic on radio repair, circuit theory and "hints and kinks."
Anyone who is interested could join the reflector, this includes both newbies and those with years of experience.? There doesn't need to be a formal instructor, we can just go through the text chapter by chapter and any questions can be posted and multiple answers shared. ?
I for one have never been to an NJARC repair clinic since I live so far away but I would think that the experienced repair people all have methods and short cuts not covered in the above text but are none the less valid and worth sharing within the group.
Thoughts?Jim

Hi Joe

I'd like to take your request and turn it into a suggestion. I also belong 
to a car club which periodically holds technical workshops. Perhaps one of 
our more experienced members can schedule something similar for all of us on 
the subject of radio repair. I would love to join such a meeting to learn 
more about the subject. How else can the knowledge be passed along to us 
newbies. I've only been a member two years.

Thanks in advance.

Gang,

As NJARC Technical Coordinator allow me to weigh in on this thread. The 
club is a interesting combination of people, some of us spent a big 
chunk of our lives with our faces stuck to an oscilloscope, and others 
did more ordinary and sensible things, but still have a deep interest in 
radio.  Obviously, it would be a good thing if the club could provide 
some remedial education to allow the second group to catch up a little 
bit.  The day-long Oscilloscope School is a good example.  
https://www.youtube.com/watch?v=8ZKMrzTGxLQ
(Hmmm, comes up right on top if you search YouTube for "Scope for Dopes")

Here another example on Radio Restoration: 
https://www.youtube.com/watch?v=_OYw2wfdSCs
(Who's that kid with the hair?)

The problem with both of these is that you're jumping into the middle a 
rather deep subject.

My recollections from US Army Signal School at Ft. Monmouth in 1968 is 
that it took three full week of classes just to cover the basics.  We 
may not have enough Saturdays left to go through the whole thing, even 
if we had someone to organize it.

I briefly browsed around for some suggestions this morning.  Take time 
to look through Module 1 (of 24) of the Navy correspondence school, and 
I think you'll get the idea.  A competent technician needs to have at 
least been e\briefly exposed to this material.
http://rtm.ar88.net/resources/Training/Navy%20Module%201%2014173.pdf
This is modern ca. 1998.  They barely mention electron tubes.

There are some vintage electronics book available.  Here's one:
http://rtm.ar88.net/resources/Training/Basic%20Radio%20-%20Hoag%201942.pdf
I hacked at this file to fix the page numbering so the TOC and Index 
will work.  And did Optical Character Recognition on it so it can be 
searched, and one can cut and past text from it.

All of the above is no substitute for have someone actually teach this 
to your.  I'm open to solutions.

Regards,
Al

Subject: [NJARC] Metting webcasts
Message-ID: <CAMh_1mWzqCRGXqwh2t0ga9Ws2kiRbH8KbZSVRr+egj6VmJoOJA@mail.gmail.com>

If you were one of the people 'tuning in' to the webcast of last Friday's
meeting on the web you may have noticed that the sound was noticeably
clearer than it's been recently.  I watched my first meeting from away last
summer and it was tough to hear what was going on.

I've been trying to figure out a way to do a better job than just pointing
a phone across the room toward the person speaking.  That works, but it
sounds terrible.  The solution had to be easy and affordable, 'cause I'm
lazy and cheap.  The problem is it's not easy to connect a phone to a PA
system.  I found an audio adapter circuit that promises to make things
better, but last night I had an inspiration for a 'trailer trash"
solution.  If you were there you may have noticed the duct tape wrapped
around my phone.

If you watched the webcast last night, I'd be interested in hearing what
you think.  If you missed it, you can check it out on our Facebook page:

Kevin,

Yes, but you must be grounded in the fundamental.  Everyone is at a 
different level, so it's difficult to do anything in a short session.  
One has to know what a resistor does.

For instance,  I just did this for another teaching project.  How much 
sense does it make to you(s):


Yeah, I know, there's no tubes.  Could you use an ohmmeter to find the 
problem if the 1.3V test point indicated 3.0V and the 0.9V point said 0.0V?

Hello All!

I was wondering if anyone in the club would be masochistic enough to
tutor me a bit with regard to radio repair. I've been a member of the
club for nearly five years and, while I can test tubes and replace
capacitors, I know very little about how the circuits function nor do
I know much regarding diagnosis and troubleshooting.
So, would anyone in this wonderful community be willing to share their
knowledge with a youngin like myself?

Have a good night!

Joe Giliberti

Perhaps those looking to learn electronics in the structured way that Al et
al. recommend could use the 5-volume Rider set available at
http://www.americanradiohistory.com/Bookshelf_Technical.htm to familiarize
themselves with concepts, laws, etc. before anyone actually organizes a
course.

What an amazing web site.  It's hard to believe that this group took the
time to scan so many thousands of books and magazines. But I'm glad they
did.

Thanks Alex!!

Hi Phil,
Does the club have transistors as well as tubes for sale?
I have a Philco set needing an output transistor
Part number on it is 185236.

I am not able to attend the Christmas party this year, since it is the same
night as my company party.


Thanks,
Nick

Phil,

Get us a model number for the set, or better yet a link to a  
schematic.  I should be able to dredge up something appropriate.

OK, from Wikipedia <https://en.wikipedia.org/wiki/No_soap_radio>:

"This joke requires the joke teller to have at least one confederate who 
already knows the joke and secretly plays along with the teller. The 
joke teller says something like "The elephant and the hippopotamus were 
taking a bath. And the elephant said to the hippo, 'Please pass the 
soap.' The hippo replied, 'No soap, radio.'" [2]

At this point the confederate (who is pretending that this is the first 
time they have heard the joke), starts laughing hysterically, as if the 
joke was very funny. The other person who was told the joke is then left 
wondering why it is funny, and why everyone else "gets it", but they do 
not. Typically, the recipient of the joke will pretend to get it and 
laugh along with the others just so they won't look stupid. The joke 
teller and the confederate then laugh at the recipient for pretending to 
get it, because the joke is, in fact "ungettable". "No soap, radio" is 
not a punch line, but a nonsensical statement."

Who jnew?

Boy,

I haven't heard that absurdist punchline since high school, but I'll have
to ask my classmates on Facebook the opening, because it sure wasn't two
penguins in a bathtub. . . .

I cannot tell a lie??.

The first thing that came to my mind was (The first penguin saying) - that?s a funny way to check to see if the GFI - (ground fault interruption) is still working!

But this is how I remembered it -

Go to ?You Tube? and look into the search box - The Monkey Joke.  (Make sure the kids are asleep first)

Message-ID: <158ac2015b1-46a4-e741@webprd-m98.mail.aol.com>

I've come across something I haven't seen before.  It's a Surge Limiting Resistor.  This is going into a Philco C-579.  (Pg 16 in Beitmans 1955)  It's a little plastic case radio.  It also has a phenolic board with copper tracing.  That's seen better days as well.  It seems the only thing holding me back is this resistor.

Can anyone lead me to a source for them?  The schematic says 880 ohms when cold / 50 ohms when hot.

Thanks in advance.

isn't that the same thing as a varistor\thermistor?  like the CL-90?  (I think CL-90 stands for current limiting).

Hi Joe,

It's hard to imagine how you could build a radio cheaper than this.


It's a superhet without an IF amplifier fer Pete sake!!

As for WR1, you might try two of *these 
<http://www.digikey.com/product-search/en/circuit-protection/inrush-current-limiters-icl/656273?k=&pkeyword=&v=317&pv679=2&pv680=182&FV=fff4000a%2Cfff80391&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25>*in 
series.  Failing that, a 50-ohm 5-watt resistor should do OK.

Good luck,
Al

I believe the varistor should work.  This reminds me of a problem that I have not been able to solve:

"how to you use voltage measuring equipment, aka analog oscilloscope, to measure a very short transient such as a current surge? "

The first part I think is solved using a current probe, bench made or store bought, but how do you record the high speed transient.....the old fashioned way....poloroid camera on scope.. and single triggered trace?  What do you use for the trigger?  A scope with memory option makes second part a lot easier...I imagine!

Hi Jim,

    This opened up quite the conversation yesterday.  Al Klase made what seemed to be a big issue rather simple.  Sure I could go and get the varistor (mail order for me) or I could just drop in a 50 ohm 5W resistor.  The 50 Ohm resistor is the value for the radio under normal operation.  The schematic called for 880 ohms for the start-up, then to drop to 50 ohms.  If I had the room, I could have put a monster (for this size radio) 10W resistor in there.  It didn't take long to make the choice.  Then I got to thinking, all I needed to do was to bleed off some of the unused voltage and have something to absorb the inrush current.  This little tike uses 4 tubes, 50C5, 35W4, 12AU6 and 12AV6.  It's no wonder the original part blew up.  It is about the diameter of a pencil eraser and maybe 3/8" thick.  It couldn't take years of heat.  

    Here in Maine, AM during the day is a pipe dream.  What I couldn't believe was that I was picking up a station, in the basement, at 10:30 AM, from not too far from here on it.  You can't do too much to tweak it to hear better.  This was made for local station use at best.  I'll be curious to see what I can hear with it tonight. 

    So, I hope some of us learned a little bit about varistors and alternate solutions.  Just in case you missed what this radio is, look for a Philco C-579 of the 1954 vintage.  Curiously, someone actually sold one of these a few years ago for $95.00.  Who would have guessed?  I picked this up at a local flea market for $10 and it's in pretty good cosmetic condition.  I attached the Beitmans page if you care to take a look.

Regards and thanks.

Joe Devonshire

Well, for the anal-retentively cautious among us, this might be one of the
few good uses for a Variac.  Not sure it would ever be worth the trouble,
but I do know a couple of people who are compulsive about 'soft-starting'
stuff by bringing up the voltage slowly.  Not to re-form old filter caps,
but to avoid the inrush current situation being described here.

There's got to be an easier way...

Hi JimA current probe will work and is easiest to use. ?So would a small value resistor in series with the load. ?You then measure the voltage drop across the resistor which is proportional to current. ?Care needs to be taken since the scope voltage probe is referenced to ground. ?This is where an isolation transformer comes in handy! ?You have to power the radio from an isolation transformer so that the ground connection of the scope probe doesn't short the AC line voltage to ground. ?
You could also put the resistor in the circuit near the common return of the AC line if you don't have an isolation transformer handy. ?This should put the scope probe ground within a volt or two of neutral but it is still a crap shoot and not worth the gamble.
A decent o'scope has delayed triggering so you should see the whole pulse of inrush current. ?You are correct, the old fashioned way to record a waveform was with a camera. ?Later, storage o'scopes using special CRT's were used. ?These would memorize a waveform for later analysis but the image will slowly fade over time. ?I have an old HP scope that has this function. ?Newer digital o'scopes of course write the waveform to memory and the image will last as long as you like.
You could possibly use your smart phone to record the waveform displayed on the o'scope CRT for later viewing if it is possible to either slow or stop the recording during playback. ?I don't know if this is possible since I have never tried it.
Since voltage drop is proportional to current through a fixed resistance, any resistor will act to limit inrush current. ?This is the purpose of the small value resistor used with Selenium rectifiers. ?The resistor limits capacitor charging current to a value that the Selenium rectifier can tolerate without destruction. ?Varistors or other devices that change resistance value with temperature just do this job better.
The wattage rating of the current limiting resistor just has to be sized for the normal current needed by the radio plus a safety factor of two or so. ?Sizing the resistor for the peak inrush current is just over kill. ?The Selenium rectifier current limiting resistor mentioned above was purposely sized on the low wattage side to also act as a fuse in case of rectifier or capacitor failure.Jim

Going by the tube line up, this radio has the famous "Autodyne Converter"
circuit. Look it up for a description. In a nutshell, it is an all American
4 that was a lower cost radio for inner city use where signals were strong
and peoples incomes were low. GE made clock radios with this same circuit.
The resistor is needed since the tube lineup is 12 volts short of the All
American 5 filament total to make up the line voltage. I doubt that surge
protection feature is needed with the stability of today's power line
voltage. Back when this radio was new however, power surges would have been
more of an issue, especially in big city industrial areas where many of
these radios were sold.

Charles,

    Up here in rural Maine, our power is up and down.  Generally I see it at 117, but I've also seen it go up to 125 while I was watching the meter on the bench, and then go back down.  Honestly,  I was impressed that it picked up a signal, in the basement during the day, from a 5KW transmitter about 50 miles away.  As you can see, there's nothing much to adjust and it didn't matter much when I tried.  Anyway, it's been fun learning more from this.  BTW... I did run this from the isolation transformer. 

Joe

circuit. Look it up for a description. In a nutshell, it is an all American
4 that was a lower cost radio for inner city use where signals were strong
and peoples incomes were low. GE made clock radios with this same circuit.
The resistor is needed since the tube lineup is 12 volts short of the All
American 5 filament total to make up the line voltage. I doubt that surge
protection feature is needed with the stability of today's power line
voltage. Back when this radio was new however, power surges would have been
more of an issue, especially in big city industrial areas where many of
these radios were sold.

Jim,

The websites, both njarc.org and rtm.ar88.net are on the Canaca server 
in Toronto.  The email reflector, njarc at mailman.qth.net, is an entirely 
different thing.  I did see a little down time today that might have 
been a Canaca problem, but not sure it wasn't a local issue with FIOS.

Who knows?
Al

With 99.99% reliability (or whatever fictional number they're promoting)
we're 'guaranteed' to be down briefly at least a few times a year.  Most of
the time we're back online before I can even send in a trouble report.
Sometimes before anyone even notices.  Only exception was the big server
meltdown of a couple of years ago when we were offline for a week or two.

But...

Please send me a note any time you notice anything funny going on.  I might
not notice it myself so 'trouble reports' from the field are always a good
thing.
