Re: [AMRadio] Need help identifying National part
Hi John, I checked my Radio Parts Master catalogue for 1964, as well as the catalogue sections of the 1948 1940 ARRL RADIO AMATEUR'S HANDBOOK --- nothing, nil, zilch, nada... I wonder if that part number is really a National number, per se...? Perhaps it's the part number of the MANUFACTURER who originally purchased the part for his OEM application... Hammond Manufacturing did the same thing with their transformers: they were custom made on occasion for a specific end user in quantity, with a unique part number affixed to the transformer that meant nothing, specifically, to Hammond itself, once the contract ran out (or at least I've been told as much by a Hammond engineer). Good luck, in any event...! ~73~ Eddy VE3CUI - VE3XZ *** - Original Message - From: John King k5...@yahoo.com To: amradio@mailman.qth.net Sent: Friday, December 26, 2008 11:22 AM Subject: [AMRadio] Need help identifying National part Have New Old Stock National part number SA1288. Appears to be a transformer with two spade bolts to bolt to chassis and has the National diamond emblem which has NC in the diamond. It is tar filled and has five black leads coming out of it. It is shaped like a LARGE IF can but has no adjusting screws or slots as it is completely enclosed. The dimensions are: 4 H X 2 3/8 D X 1 15/16 W. It weighs about one pound. It is NEW and unused still in the National Box. Looks like a transformer of some sort such as an audio transformer from one of the OLDER National receivers that had considerable audio output for a receiver such as maybe a pair of 6V6 tubes or something of that nature. If you have the facilities to cross reference the part number, I would appreciate if if you would let me know what it is and which piece of National gear it was made for.

Re: [AMRadio] Tower ID
Hi Jim, Those part numbers you quoted --- as well as the general shape of the tower --- sound an awful like parts of am old Delhi Antenna Towers-brand tower that I've had for some 27 years here...! Indeed, I use one to elevate my Hy-Gain TH3 Mk 3 yagi: 48', self-supporting, with a taper from wide at the base, to narrow at the very top. Each individual section is 8' long, too... The part numbers that I have on hand here are similar to those that you quoted, but slightly different: ex., the individual factory part numbers used in my 48-footer are DMX7 (bottom section), through to DMX2T (top). Your part numbers may well be indicative of new numbers assigned to Delhi products as a consequence of Wade Antennas purchasing the company awhile back. Both outfits were / are Canadian-based, here in southern Ontario. Click onto this website for more dope on Wade: http://www.westernequipment.com/Docs/DMXN%20Announcement.pdf I hope this helps! The old Delhi's were VERY rugged systems --- I couldn't be more pleased here with mine...and judging by what's on the Wade Antennas website, they're even better now...

If you are familiar with the Rohn BX series of towers, it is similar. The Rohn (now manufactured by Thomas Shelby) has straight legs from the bottom of each section to about 2 ft. from the top where it angles inward to mate with the next section. This tower is not built like that. The metal and construction are the same and the sizes are the same; however each of the legs are straight from bottom to top. They reduce in size like the Rohn version but they are angled inward from bottom to top. The Rohn towers require 9/16 bolts in the bottom 2 sections whereas this tower uses 1/2. Also the towers have a number stamped on the cross braces to identify the section. The numbers on this tower is DBX-A-121 to DBX-B-134. Does this mean anything to anyone?

Re: [AMRadio] Fighting deed restrictions
Hi Guys, It just totally escapes me why a Ham would dole out $$$ for the BIGGEST investment in his life, i.e. a house, and then whine about existing covenants against antennas... Doesn't it make supreme sense to check things out first, BEFORE signing on the dotted line...? (HINT: think of the old ...never jump into an empty swimming pool / look before you leap adage for comparative purposes). When we were house-hunting here 18 years ago I specifically told our real estate agent to watch for antenna restrictions / covenants: if there were any, we simply crossed that property off our list. Simple. Why buy your way into the heartache disappointment of future, on-going firefights over your right to raise an antenna...? Why in your right mind would you want to raise the ire of your neighbours by becoming the target of blame for each every blip on their TV screens / telephone static / loss of internet connection / ad nauseam...? Surely there must be enough suitable domiciles available for sale in the country that one's choices would NEVER have to be THAT limited...unless, of course, one is afflicted with some sort of a demented martyr's syndrome, or, one thrives on the anataganism of others, upon personal chaos... ~73~ Eddy VE3CUI - VE3XZ * - Original Message - From: D.

Same thing. Or in Italian, you tell 'em Fa'n culo! Something that might be worth a try would be to cross out the restrictive language in the contract in permanent ink and initial in the margin next to the stricken text, before signing it. Sometimes the seller of the property or the real estate agent will be too eager to close the deal, and not notice the modification, or he may simply not care as long as he is getting his money out of the deal. Once it is registered at the courthouse in that condition, the crossed out language is legally voided, too late to do anything about it. I know of at least one case where the buyer of a property did that (although it had nothing to do with amateur radio) and it worked. OTOH, I also have heard stories of where people had been living on a property for decades without restrictions, and then new highly restricted developments with HOA's popped up on all sides. The older property owner was tricked into signing a form to join the HOA and accept its restrictions. He thought he was signing an agreement to settle a road easement issue with an adjoining property owner, but voluntary HOA membership was hidden in the fine print. So even if you are a long-time property owner in a locality, be very careful about any agreement you sign with neighbours regarding real estate issues.

Little more than a touchy-feely-warm-and-fuzzy tome, that each month shows some new 8 year old seated in front of a synthesized transceiver, and page after page of ads.

I hang my head in shame over what has happened to this once great hobby where people were somewhat technically competent. Those that lacked technical skills at least learned a bit of theory to at least have a basic understanding of the operation of their equipment. At 44 years old, I'm a relative youngster in ham radio. I build and restore vacuum tube equipment. I also play the guitar. The electric guitar fraternity seems to embrace homebrewing far more than the amateur community does today. Most good guitar amp designs are still vacuum tube based, including modern designs. People regularly modify their amps or build clone designs. Yes, high voltage. You learn the proper precautions. Seems rather funny that a musician might be more apt to work with electronics than a ham radio operator. Modern electronics is too complicated, tubes are too dangerous - it's no wonder that electronics isn't even taught any longer throughout most of the school system. I'm really beginning to question why I continue to support the ARRL. At first when I saw the cover of this issue, I had thought there would be all these neat projects from the Homebrewer's Challenge.

Gosh, if that were preferable...maybe we should all just revert to 100% CW for the ultimate in narrow band communications. It seems to me that when people are enjoying something, there always have to be counter forces that continually try to spoil it for them. Many, if not most of the complaints against AM are generated by persons who seem to delight in creating discourse and ruining other's enjoyment of the hobby. Instead of trying to get alongthey want it all their way, or not at all. They crowd up close to AM QSOs and then complain about the bandwidth taken up by AM. They continually complain about splatter...when often they are creating more havoc themselves by overdriving linear amplifiers and exceeding the bandwidth of most properly operating AM transmitters.

Re: [AMRadio] Wanted: Receiver - New England
Hi JT, This may not exactly fit the specifics of your needs or requirements, but for my money, one of THE best tube-type receivers (and it was designed built near the zenith of the vacuum tube era) is the R-4 series from Drake... They are still readily available, AND at good prices --- especially the series preceding the C version (which apparently needs a lot of after-market hot-rodding anyway to make it really come alive, anyway) Now, if you want something without 160-meters --- but at HALF the price of an R-4 --- get yourself a decent Heathkit SB-301. Two caveats: if you want 160 with the R-4, you'll need a 12.6-MHz crystal...and if you want AM with the SB-301, you'll need an AM IF filter (the SB-310 wider unit preferred in this application). My $0.02 worth, anyway... Either way, you'll get a classic, hollow-state receiver, that is readily repairable by yourself, that's stable, sensitive, and flexible...AND it won't cost you an arm a leg, either! ~73~ Eddy VE3CUI - VE3XZ * - Original Message - From: JT Croteau [EMAIL PROTECTED] To: Discussion of AM Radio in the Amateur Service amradio@mailman.qth.net Sent: Saturday, February 16, 2008 10:16 AM Subject: [AMRadio] Wanted: Receiver - New England I'm going to be looking for a receiver at the beginning of the month (hate getting paid once/month) and wondering if anyone has anything they'd be selling or have any leads on.

Re: [AMRadio] Using Heath SB 610 Monitor Scope to monitor modulation onAM transmitter
Hi John, The SB-610 has been an absolutely invaluable aid here at my stations, in both the CW and voice modes (AM, as well as SSB)... All I do when monitoring 'phone transmissions here is to place the 'scope into a trapezoidal pattern. I adjust the vertical gain such that a carrier makes the line about 2/3 the height of the screen, or so, and the horizontal gain is set so that the modulated triangle is about as equilateral as it can be... When modulating 100%, the pattern should, indeed, be a full, equilateral triangle. One thing that I neglected to do until YEARS later was to pull the top RH knob out --- that's the one marked CLAMP --- whenever using the trapezoidal feature: by doing this, there is no image on the face of the scope until you key-up your transmitter. If you leave the knob in all the time, you'll eventually get a spot burned into the inside face of the CRT, like I did with mine here... The clamp feature keeps the point deflected off-screen into the RH side of the CRT --- as soon as you hit the transmit button on your rig, the line zips out from the right, to the centre of the tube, like magic...!

Elmer here was my very first SW receiver: a beat-up, 3rd hand, $40.00 Hallicrafters S-77A, that I found through the want ads in one of my Dad's union newsletters. Looking back, it was surely a good thing that this receiver had the many shortcomings that it did, for these very deficiencies taught me all about improving the performance of things electronic, and made me appreciate the fine art of homebrewing --- or, perhaps more accurately, it put a face to that most noble of Amateur activities, i.e. ...tinkering and experimenting... To whit: -Being an AC/DC receiver, its shocking (literally!) performance made me appreciate the outboard installation of an AC isolation transformer; -Its poor sensitivity on the higher bands forced me to build a regenerative pre-selector; -Its poor selectivity taught me about crystal lattice filters, and Q-multipliers (I installed a Heath QF-1), and passive audio filters (I built one using 88-mh. telephone toroids); -Its poor dial calibration inspired me to build a crystal calibrator, using one of those $4.50 100-KHz crystals that Jan Crystals used to sell back in the day; -Its poor stability on 20-, 15-, and 10-meters compelled me to build a crystal controlled down converter, and, On on it went! In fact, the VERY FIRST working Ham station I ever saw was my own --- and with the singular exception of that receiver, the station was entirely homebrewed... It held sway at VE3CUI for some 12 years --- the transmitters may have come gone in that time, but the old receiver remained in its well-earned central spot atop the operating position.

Re: [AMRadio] Re: P.S. - you get to run 1000W input on AM up here
Hi Guys, Canada is nothing BUT a nation of ex-pats as it is...! I know --- my parents were part of the great wave of immigration from Europe that swept into the country in the years after WW2. Have you ever heard of the expression DP...? Well, that was about as vile a name as the n word is to-day to Afro-Americans, only DP --- or, Displaced Person was the slangy name entrenched Canadians threw at everyone who was new to the country back then. It was NOT pretty. We were made to feel less-than-human by a large sector of the population, and one could practically feel the bias prejudice in school, on job sites, etc. But enough of that... Hey all you Americans --- as long as you've got a passport, that's about all you'll ever need to come up here for a visit. Whenever we cross the border to visit our son in Maine, all we ever do --- both ways --- is simply show the guard our birth certificates our passports, we're home free (but I've also read somewhere that Americans, as a nation, have one of the LOWEST per capita ownership of passports of any country in the world --- maybe that's why a lot of you guys think our currency is the peso, and that we speak French in the province of Toronto...eh?). So get those documents ready, folks --- because if there really IS such a thing as global warming, there'll be hordes of you flocking north of the border not for the snow back bacon, but for the temperate weather, and dry land...! ~73~ Eddy VE3CUI - VE3XZ ** - Original Message - From: D.

I hear you need to have a job lined up, or at least be self-sufficient. Central heating, parkas, warm toques (?!) and gloves are great and all that but how good is the pizza and hot cocoa?? Inquiring minds wanna know. And so do I. And thanks. 73, Terry Bakowski KC9KEL Plus, Canada's Medicare covers people of all ages, not just the elderly. And regarding the toques, one to keep you warm, and there is less paranoia about the other variety than in USA. And Canadian ham bands have no subbands. But it has become much more difficult to get landed immigrant status (more or less the equivalent of the US Green Card) than it was during the VietNam era, when all you had to do was make your declaration at the border crossing. And apparently it is now difficult to enter Canada even for a short visit. My daughter's boyfriend had planned to take a camping trip to Thunder Bay back during the summer. He drove several hundred miles from Nashville to the border crossing, and they refused him entry because the computer showed that he had been busted at age 19 for under-age drinking in Tennessee. What was really so stupid about that was that it should have been a moot point since 19 would have been legal drinking age in Canada, and when he tried to enter the country, he was 24, well past the drinking age. Besides, what does under-age drinking 5 years ago have to do with being a risk to Canada? Makes me wonder if it would be worth travelling from distant reaches of the US, if you could unexpectedly be refused entry because of some hassle you might have forgotten all about. Most of us probably have something trivial like that on our past record. There is a down side to the ham radio issue. Canada's regulations impose a 6 kHz bandwidth limitation for AM. But that is apparently taken about as seriously as the USA's p.e.p. bullschzit. I have never heard of an AM'er on either side of the border being cited for exceeding either one. And I hear Canadian AM'ers describe their rigs in detail, with no mention of any measures taken to suppress the highs.

Hi Rick, Not to belabour the point, but a serious contestor just has no time for the proverbial ...old buzzard transmission typical of AM operations...besides, he's just plain, NOT interested: he wants to maximize his QSO total, final score. Period. He KNOWS he sounds good, when he's racked-up a big pile of QSOs at the end of the contest... Love it, or leave it, but that's just the nature of the beast, a fact of life.

Yet, here in Canada, which is --- for better or worse --- officially a bi-lingual country (English French), one can now see street signs and billboards in certain sections of the provincial capital city of Toronto that are written wholly in CHINESE. There is even a 100% Chinese AM radio station on the BC band... So guys, just go ahead open the door a crack, and see how many more feet will force themselves in between it the door frame...

Re: [AMRadio] USPS Changes May 14
Hi Bry, FedEx may good for domestic shipments, i.e. U.S.A.-to-U.S.A., but for INTERNATIONAL deliveries --- like the U.S.A. to Canada --- FORGET it!

I would pay 50 cents for a stamp, but really they are so messed up it is pathetic. Thank God for FEDEX! As you know I ship a lot, so it is interesting to me the changes that USPS is putting in May 14. Rate increases on everything of course--that's standard. But their parcel post service is actually changing quite a bit. Foreign surface mail shipping has been eliminated. It's all air mail as of May 14th. That should really cut down on the number of boatanchors crossing the pond. Global priority mail is now limited to 3 ounces. That kills the best way to ship small parts, mics and accessories overseas inexpensively. Parcel Post--ALL packages now have to be measured and are charged more as size goes up--not just weight. That should certainly drive a lot of shiping into UPS/FedEx camp. There's many other small changes.

Re: [AMRadio] Ranger... good news, bad news
Hi Guys, I haven't really been following this thread all that closely, but has any mention been made yet about the fact that the MAXIMUM amount of RF output carrier that one can safely extract from a linear amplifier tube in AM mode is equal to ONE HALF of the tube's plate dissipation...? Ex. an 813 has 125-watts of plate disipation --- in AM linear amplifier mode, that'd translate to just under 65-watts of AM CARRIER output. I used to run a pair of 813's in AM linear amplifier service for a total of 125-watts carrier output. A 'scope --- like a Heathkit SB-610 --- in trapezoidal mode is absolutely invaluable in setting up an amplifier this way... ~73~ Eddy VE3CUI - VE3XZ - Original Message - From: Gary Schafer [EMAIL PROTECTED] To: 'Discussion of AM Radio in the Amateur Service' amradio@mailman.qth.net Sent: Tuesday, November 07, 2006 8:20 PM Subject: FW: [AMRadio] Ranger... good news, bad news -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jack Schmidling Sent: Thursday, December 07, 2006 5:49 PM To: Discussion of AM Radio in the Amateur Service Subject: Re: [AMRadio] Ranger... good news, bad news Gary Schafer wrote: If you want to run 125 watts carrier out of the SB200 on AM that means you need to tune the amplifier up for 500 watts or a little more output with the load and plate tune controls on the amp peaked for maximum output with a given amount of drive. Not sure I understand the why of this. I did all as you suggested but found when I was done that the plate tuning of the amp was exactly the same as if I tuned it originally with the 100w carrier. The dip was exactly in the same place and the loading optimum is so broad that no change could be noted. Watching the scope on the output of the amplifier should show the modulation peak voltage double what the carrier voltage is on the scope. If it doesn't you haven't tuned up properly. Interestingly, the only way I get the peak voltage to double is with the ricebox. I can never seem to get more than about 50% increase with modulation. js The peak envelope power of an AM signal increases by 4 times over the carrier power with 100% modulation. The linear amplifier must be tuned at the peak envelope power level or the peaks will never reach full power, the amplifier will flat top and splatter and you will not sound good. How much drive power did you have when tuning up the amp? Were you using a rice box to tune the amp or the ranger? If you don't see the scope voltage double with modulation you haven't tuned up right. If you adjust the scope to say 2 centimeters with carrier then the modulation peaks should hit 4 centimeters. 73 Gary K4FMX __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net
