From amradio at mailman.qth.net Wed Oct 1 11:36:04 2014 From: amradio at mailman.qth.net (CL in NC via AMRadio) Date: Wed, 1 Oct 2014 08:36:04 -0700 Subject: [AMRadio] Typo or accurate? Message-ID: <1412177764.13053.YahooMailBasic@web160603.mail.bf1.yahoo.com> I have an LM10 freq. meter that I run off an AC supply. On the schematic I retrieved from the internet, it shows a HV strapping option which is internal to the unit. It shows entering B+ going through R103 and routing options of the B+ of 260-475 going to one terminal, and B+ of 200 to 260 going to another. The issue here is that the 200-260 terminal has an extra resistor, R116, cut in line going to the neon tube regulators and the higher voltage option does not, which seems bass ackwards. Is that a misprint on an old schematic, or does somebody have any insight to this? I'm still waiting for my approval to join the military reflector, is anybody home there?

Photo #4 is of the 3 contact wafer. I am nearly certain that if you install that wafer and operate 20 meters you will see it go up in flames. For you that have an NCL-2000 look at your band switch and you can verify whether they are the same as the replacement. Please post the results.

None the less, if you read this with an open mind, you will at least find it interesting and at best will provide a fix for the most troublesome failure in the NCL-2000. The band switch on the NCL-2000 was originally made by OAK using coin silver or spring hard sterling for contacts and rotor wipers, not silver plated copper. The new Chinese switches are silver plated copper with slotted contacts --- Beware. If you observe the original contacts they are solid not slotted surface. Further, they were rated at slightly over 12 amps and the configuration used a pair of contacts combined for 24 amps. The design by OAK assumed safe use at up to 150% of design criteria. The current carrying capacity of that switch is quite adequate for the 2KW transmitters that used them, specifically the NCL-2000 and SR-2000. The notion that the current carrying capacity of this switch is inadequate for these amps is misguided. The only way to exceed the switch limits is to run AM in high power mode. Of course doing so is a bit feeble minded and proves that survival is for the fittest. Do a bit of analysis. How many have failed when using the 80, 15, and 10 meter bands? Very few and that was likely operator error. The 40 and 20 meters bands comprise the majority. Why is that? The post mortem reveals the source of the malady. The front wafer is almost always the apparent starting point with the arcing propagating to the rear wafer. In that the front wafer carries less current than the rear and is usually the point of failure, doesn?t it suggest that current is not the culprit but voltage arcing is responsible? The SR-2000 uses the same front wafer design and the A level radio had the same frailty. The Hallicrafters engineers had the financial resources to fix the problem and all of the release level trials verified the cause, voltage arcing!! . I am certain that the National engineers became aware of the problem early but were in too much trouble financially to fix it. It is also very apparent that the service people knew that there was a problem but were oblivious of the cause. The first redesign by Hallicrafters engineers improved the failure rate dramatically and the second eliminated the problem, yes using the same switch. There you are, the switch is not the problem but the configuration is. The first redesign occurred in 1967 and the second 1971 four years later, about the same time that production ceased. It is inappropriate to fault the National designers because every power engineer at the time using the switch for the same purpose made the same error. The switch was appropriately designed to support the application --- just incorrectly configured. The standard National front wafer can be refitted using the same components to equal the first redesign by Hallicrafters and with some thought the second and final design by the Hallicrafters engineers. There is a lot more to this story and if I could put my hands on a functioning complete switch I can write what has to be done to replicate the first redesign and the second. If you have one and can temporarily part with it, send it out and I?ll write a yellow brick road paper. Then maybe the NCL-2000 switch legend can go to sleep. The SR-2000 has been reconciled long ago. I solicit questions and conversation but if you feel belligerent please don?t respond.

I also have gotten lucky recently and found a nice 755A VFO. If someone has the panel off a 500C power supply/VFO that they are not going to use, I would like to buy it so I can just install the "innards" and dial of my VFO into that panel and my power supply chassis. I don't need ANY more clutter on the desk if I can help it, and this looks like a nice way to do it to me. In fact, I'd sure like to get the attached chassis from the power supply as well, if possible. If you have such a thing, please contact me and let's see if we can come to an arrangement. My Globe King appears to be in pretty fair shape, and should make a nice addition to the shack. 73, and thanks, Don, WB5HAK --- This email is free from viruses and malware because avast!

The broadcasters have thinned out in recent years, to the point that swathes of QRM-free open space can often be found between 7200 and 7280, particularly around 7225, even during peak evening operating hours in N. America. The most obnoxious broadcaster ever has to be that one that comes on at 0400 GMT on 7295, starting off with nerve-grating martial sounding music and then switching to a middle eastern language with Islamic prayer call. That thing's lower sideband wipes out everything above 7280. I wonder if anyone has figured out where it comes from. Their signal practically paralyses the front end of my receiver. And, we mustn't forget the longtime AM operating frequency in the vicinity of 7160. It was pretty much abandoned as the broadcasters gradually crowded out amateur activity in that part of the band during the 80s, but when most broadcast stations vacated 7100-7200 a few years ago, a substantial amount of AM activity quickly returned. Unfortunately, once the initial novelty wore off, AMers gradually, one at a time, migrated back to their old stomping grounds and AM activity began to dwindle. Now, it is rare to hear any AM activity at all near that frequency other than some operation out of 5-land during the daylight hours. The same thing happened in the lower end of 75m after the FCC expanded the phone band. Don k4kyv --- This email is free from viruses and malware because avast!

There must be some other reason why you do not achieve that amount of power out. Also, when you operate with that high carrier power you should probably improve the cooling in the power amplifier and make sure the plate supply transformer is rated for around 700 ma to the final or more, CCS. If you have not done so, look at the output of the exciter with an oscilloscope; do the same with the power amplifier. If they look clean, linear with no audio flat topping or other warning signs then I suspect there is a problem with the input and or output matching networks on power amplifier. 73 Rob K5UJ On Wed, Oct 22, 2014 at 12:20 PM, rbethman wrote: > I am currently using a Kenwood TS-2000 on AM. > > It puts out 25W on AM.

We had a QSO yesterday on 40M AM, and he was Q5 here into Maine from VA. I concur with the replies I've seen on this list since that 100W PEP is adequate to drive a pair of 3-500Zs to the legal limit (or very close), so no intermediate power amplifier is needed. 73, -Larry/NE1S From amradio at mailman.qth.net Wed Oct 22 15:06:03 2014 From: amradio at mailman.qth.net (W4AWM via AMRadio) Date: Wed, 22 Oct 2014 15:06:03 -0400 Subject: [AMRadio] 40 mtr AM open In-Reply-To: References: <001801cfee16$3d07db50$b71791f0$@charter.net> Message-ID: <8D1BC425BEF83D5-F8C-399A@webmail-vm177.sysops.aol.com> When ten, Fifteen or Six meters are open, that is news.

I am currently using a Kenwood TS-2000 on AM. It puts out 25W on AM. The modulation is pathetic, but this is what I have to live with due to physical issues. If I can get that 25W to about 100, then I'll get a much better signal out of the Amp Supply LK-500ZB. What would a small intermediate amplifier take to make? I just need to stay "relatively" close to what the built-in AT in the TS-2000 can deal with. I can tune the input of the LK-500ZB to better match the output of this intermediate amplifier.

There are occasions when I'm content to sit and listen, especially if all the signals are strong and sound good, but much more often I prefer a smaller group of just one or two other operators on frequency. I've called CQ away from ghettos but get no takers, and eventually give up and go back to the ghetto to join the big group or call CQ and get a response right away. I've even moved away from a giant group, only 10 kc away and get nowhere. AM ops would rather pile on one frequency until there are 10 stations, and the group gets so big it blows up with the rotation lost, then operators bail out on it and it collapses with the frequency vacant. Then the whole thing starts over again with new stations piling on again. It's kind of funny unless you are in one of these groups that's spinning out of control. There's a catch 22: To get QSOs established away from the ghetto you have to have people tuning and listening away from the ghetto but to get them to do that they have to have people calling CQ away from the ghetto but to get that started there has to be people tuning and listening away from the ghetto... 73 Rob K5UJ From w5jo at brightok.net Wed Oct 22 22:53:32 2014 From: w5jo at brightok.net (Jim Wilhite) Date: Wed, 22 Oct 2014 21:53:32 -0500 Subject: [AMRadio] 40 mtr AM open In-Reply-To: <5446DBB6.8050807@comcast.net> References: <5446B229.30605@comcast.net><419A0646-9856-4FA0-90E5-5BB75A08D52B@sbcglobal.net> <5446DBB6.8050807@comcast.net> Message-ID: <0421A6C65ED04D5D9CDAFBC848B47A7C@JimPC> I tuned 40 meters from one end to the other just now, mostly because of Don't post about the SWBC stations.

One hits right about 7290. It happens to be Chinese. It has some English, but the majority is Chinese. I have also heard the Arabic station - BUT - no where close to being as bad as Don's experience. I attribute this to the entire difference in antenna systems. I can only be oriented in one direction due to the size of my lot. Nor can I get the same height up in the air. Don has one heck of an antenna system. I don't. That does not change what is being blasted. It is just like I have never heard a *5* call up here. I attribute it to the antenna system I'm stuck with. Somewhere around 6 years from now, I'll be relocating to Georgia. Then my antenna system will have an entirely different layout.

I also have a daily conversation with a friend on the lower part of 40 via SSB but do not go up to 7.290 region. I don't know why but just don't. With the sunspots and propagation lately it is not uncommon for me to hear stations in 9 land and far East 4 land almost daily. It will be interesting to see what signals come along this winter if the conditions settle into a stable situation.

Message-ID: <5449C552.2080907@att.net> Hi Bob (and all), The ART-13 is built like a tank, and everything about it is under-speced. The dynamotor supply originally supplied with the radio set only delivered 1150 volts B++ to the PA. The 813 is rated to 2000V CCS and 2250V ICAS in Class C amp service (CW/FM). With 2KV at 180 mA on the plate, the RCA TT-5 says it's good for 275W power output. Most guys who build homebrew AC supplies try to keep the B++ down to 1200-1500V to extend life of the tubes. The 811 modulators are behemoths. A pair of them in ICAS Class B service with 1500V on the plates will deliver an unbelievable 340W of audio! The biggest problem with the ART-13 as a general purpose amateur transmitter is threefold: First it's only designed to operate between 2.0 and 18.1 MHz (although there are a number of guys who use it on 160M AM). Second, there's no 'VFO' per se. The calibration book shows dial settings for every kHz within its range, but there's no direct correlation between the 'A' (Coarse) and 'B' (Fine) frequency controls and the frequency being transmitted. Therefore, every frequency change has to be spotted against a receiver on a known frequency. The transmitter does have 10 'preset' (i.e. memory) channels for nets and skeds. Once a frequency is programmed, a simple channel selection is all that's necessary to set up the transmitter for operation on that frequency (if you don't mind the whirring and clacking while the mechanical marvel is doing its thing). Third, the ART-13 is designed to load an end-fed airborne wire antenna. If you build some sort of matching device, you could probably load up a coax-fed or balanced antenna, but it wasn't designed for that application. Whatever you do, PLEASE don't disembowel a perfectly good ART-13 with the intent of 'modernizing' it! The mil surplus guys will hunt you down and pin your coax! For these reasons, I wouldn't put it in the same class as AM/CW transmitters of the Fifties and Sixties. It really belongs in a vintage Forties 'B-29' station, along with a BC-348 and a rack full of ARC-5 gear. My two cents worth ...

I am not knocking the ART-13, but for ham use the DX-100 was one of the most successful ham transmitters ever produced. It probably outsold every other ham transmitter in it's class. Today it is still prized by many. When new it sold for around $190 and has extremely well built transformers. 6146 finals in it are almost an industry standard. A DX-100 is much more usable on ham bands then an ART-13. Put the ART in a museum or use it as a parts rig. Lee, w0vt "The DX-100 and an ART-13 are not comparable.

In fact, I think I may have worked but one, single ART-13---and I'm not even sure about that. ~73~ de Eddy VE3CUI - VE3XZ From amradio at mailman.qth.net Fri Oct 24 12:39:04 2014 From: amradio at mailman.qth.net (Bill Guyger via AMRadio) Date: Fri, 24 Oct 2014 09:39:04 -0700 Subject: [AMRadio] ART-13?

I'm working on getting an ATC (which Collins' original version) going now and the ATC / ART-13 is the Cadillac of WW II radios. They're built like a brick outhouse and were for 1942 what Software Defined Radio is to today. The mechanical "computer" that is the auto tune device is a marvel of mechanical design and the rest of the radio matches. Art Collins blew the competition (RCA and Sperry) out of the water when the three companies demonstrated their three radios to the Navy in 1941. The demo was supposed to be on December 8, but got put off for a month or so for some strange reason............ A British Admiral who was in attendance whipped out a blank check and told Collins to fill it out for what ever it would take to finish tooling up for production and for 3-4 years worth of delivery of the radio. In AM it modulates 100% Positive and negative due to simultaneous Plate AND Screen modulation. It will also of course do CW and MCW but the antenna relay clacks in every time the key is pressed (full break in) but there is a mod on the internet from an Italian ham to do fully reversible mods to cut out the clanks and help with the spotting function. His English is a bit iffy but it's a hell of a lot better than my Italian. Bill AD5OL On Friday, October 24, 2014 7:14 AM, Dave Mayfield wrote: The DX-100 and an ART-13 are not comparable.

Checking ART-13 prices on eBay they seem to sell for less than either a DX-100 or a Viking. And they can put out much more power. I have no problems with either a DX-100 or a Viking other than their price. I just wish it was practical to make your own DX-100/Viking class transmitter today. But parts that were available 40 years ago are not readily available today. ----- Original Message ----- From: "L L bahr " To: Sent: Friday, October 24, 2014 9:26 AM Subject: Re: [AMRadio] ART-13? > What an ignorant remark!

As a 16 year old, along with a ham school buddy, we started on a Friday evening after dinner, to build a DX-100 that had been ordered by a handicapped friend. By 5 a.m. on Saturday morning we had it completed! (only defect was a bandswitch wafer 180 degrees off, which we corrected). We weren't looking to break any construction record - just thrilled to be assembling the foremost product of it's day, with an all copper chassis yet. We "burned in" the rig a few weeks prior to giving it to it's owner. What a joy to operate it! With a borrowed dynamic mike from the High School audio/visual shop, we had a great time on 15 meters AM, in addition to CW on 80/40. By the time I was older and had money, it was no longer available as a kit. OK... now, 57 years later, in helping a family dispose of their ham father's gear, I see in a dusty basement corner under a bench a DX-100! Covered in dust, unused for decades and needing a bath (who knows what else?). I load it in the van with the other gear and prepare it all for our regional hamfest. But I have to find out if the forgotten icon still works. It's on the bench now.. Anyone have a DX-100B cabinet with the top lid? ;-) Perry w8au At 12:26 PM 10/24/2014, L L bahr w0vt wrote: >What an ignorant remark! The DX-100 was a masterpiece.

Mark your calendar for 11/5 to 11/11. If it goes like the February operation it will be 29.000 or 21.425, with occasional excursions to 14.330, 7193, and 3.885. I will operate on the highest band that has good activity/propagation. As I'm going to be the only AM operator that week I have permission to operate at my convenience with no fixed schedule. However it will most likely be between 2100Z and 2400Z. So the best thing is to watch the cluster for W1AW/7 spotted in the AM Windows. - Paul KW7Y From w5jo at brightok.net Thu Oct 30 10:45:38 2014 From: w5jo at brightok.net (Jim Wilhite) Date: Thu, 30 Oct 2014 09:45:38 -0500 Subject: [AMRadio] For sale in North Texas Message-ID: <14FDE05D56C74AE3BEDDA1C9E529BBE6@JimPC> Those of you in North Texas or Southern Oklahoma may be interested in this Heath 2060 auto tuner and some coax on Craig?s list. http://texoma.craigslist.org/ele/4722509802.html Jim W5JO
