[AMRadio] WRL Globe Champion 350
Hello to you all, I'm a new list member and am delighted to find such a resource. I've been a ham for a bit over 30 years, but almost never operated AM until recently. However, my Dad, W5JHJ, has been a ham since, well, I'm not sure. Probably 62 or 63 years (he'll be 81 this September). He has had some health problems recently and, at 80 years old, is no Spring Chicken anymore. Anyway, he has some pretty neat old gear that he's maintained, which I used when I started out 30 years ago: a WRL Globe Champion 350 transmitter, a Hammarlund HQ-170 receiver, and a Hammarlund HQ-110 general coverage receiver. All of these he's had since new (the transmitter kit was purchased in March, 1959). He also has a mint condition FT-102 in superb condition. He's always maintained all of the gear in good working order and when I was very young (before kindergarten) was quite active. But, with family, the decline of AM in favor of SSB, and increasing job responsibilities, his activity waned. Recently, he's become interested in operating a bit. So, last Saturday, we fired everything up. Aside from dirty switch contacts, we got it all working fine. We even made a QSO with WA5UEK, in Plano, TX, early Saturday evening. However, as we tuned up the Globe, we noticed that the plate current swings down under modulation. Adjusting modulation gain doesn't seem to remove this tendency, though it is lessened until, of course, there is no modulation. I also notice very slight negative deflection of output power, too. Dad doesn't recall whether this was characteristic of the rig, and no mention is made in the manual. Our signal report was fine, though we were only a couple of S-units above the noise, so poor audio might not be noticed. I want to understand why we're seeing the negative deflections under modulation. I'd expect positive deflections, not negative ones. What is this telling me about the transmitter's operation? 73, Kim Elmore, N5OP Kim Elmore, Ph.D. University of Oklahoma Cooperative Institute for Mesoscale Meteorological Studies "All of weather is divided into three parts: Yes, No, and Maybe.

Re: [AMRadio] WRL Globe Champion 350
Thanks, Don! The Globe uses 2 Amperex AX9909/6083 pentodes in parallel for the PA. These tubes use indirectly heated cathodes. I have no idea how many hours are on them, but I know that Dad has a replacement pair. However, I think that indirectly heated cathodes had longer lifetimes than directly heated cathodes, as in the 809's used in push-pull for the modulators. The 809's are also original and seem to have plenty of emission. I have no idea what the expected lifetime of their thoriated tungsten filament is, but if it's anything like the filament of a 3-500Z, it's something like 20,000 to 30,000 hours. The downward swings are probably around 5% of the total I_p (about 10-15 mA). I suspect that the rig has always done this. The B+ supply is common to both the modulators and the PA. Properly tuned, the I_p for the PA is set for 300 to 325 mA and the peak current for the modulators is 200 mA. So, peak demand from the B+ supply is at least 500 mA. It's a full-wave CT PS that uses two 3B28 rectifiers producing about 900 vDC. The B+ supply uses a choke-input filter; Dad has replaced the original 2 uF oil capacitor with an electrolytic string providing about 22 uF of filtering. The transformer isn't all that beefy, so a sagging B+ supply may well be exactly what we're seeing. The 120 VAC mains seem to be pretty stiff (no dimming lights), so I'd suspect the B+ supply first, tube emission second. I've also learned that AX9909/6083 tubes may well be unobtainable, so we'll take good care of what we have! Aside: we couldn't find a set of 866A's that didn't develop arcing problems, acting as if they were poisoned. I'd dearly love to see the glow of those mercury vapor rectifiers again! Next time I'm there, we'll stick a scope probe in the air and take a look at the output wave form, just to make sure nothing obnoxious is going on. Thanks for your advice and suggestions! 73, Kim Elmore, N5OP At 09:11 PM 2/25/2003 +, you wrote: From: "Kim Elmore" <[EMAIL PROTECTED]> I want to understand why we're seeing the negative deflections under modulation. I'd expect positive deflections, not negative ones. What is this telling me about the transmitter's operation? That is not at all unusual, even though theoretically the plate meter should stand completely still during modulation. The most likely cause, if the rig uses a common power supply for modulator and final, is that modulator plate current is dragging down the plate voltage. Sometimes, even poor regulation at the 117 v. mains can cause the problem. The other likely cause is nonlinearity in the modulated stage. The final tube may be a little low on emission. Also, with screen grid tubes, the screen has to be modulated along with the plate. If this modulation is not 100% optimum, some nonlinearity will result, and the most common method of screen modulation, thru a dropping resistor off the modulated plate voltage, is rarely optimum. Sometimes the screen bypass caps will reduce the screen modulation at higher frequencies so that it doesn't follow exactly the modulation of the plate. I wouldn't worry about it unless the downward swing in plate current exceeds 5% or so of the total plate voltage. If you have a monitor scope, look at the envelope pattern to see if everything looks ok. Better still, try a RF trapezoid pattern (this requires going into the transmitter and sampling audio from the modulator), so you might not want to bother with it. The trapezoid will give the ultimate indication if there is any nonlinearity, but the envelope pattern is sufficient to tell if anything is wrong, such as flat-topping or severe waveform distortion. 73, Don K4KYV _ MSN 8 helps eliminate e-mail viruses.

Re: [AMRadio] WRL Globe Champion 350
Hi Tony, Y'know, I don't currently have room for it in my shack, but I will one of these days. If my kids decide not to pursue radio (they're 4 and 2 1/2 now, so there's still time to decide :) then I'll keep it along with the Hammarlunds. If they decide radio is fun, then I hope that they'll become as fond of Grandpa's old radios as I am and give them good, loving homes. If not, then when I go (which I plan to be a long, long time from now), they'll all be on the block. Until then, though, you'll have to enjoy it vicariously on the air. 73, Kim Elmore, N5OP At 09:48 AM 2/26/2003 -0600, you wrote: At 01:51 PM 2/25/2003 -0800, you wrote: Yep, it sounds like the Globe is broken!

[AMRadio] Power Supply Question
I wish to avail myself of the knowledge here: My Dad, W5JHJ, has a WRL Globe Champion 350 and is the original owner. He's maintained it and it works well, but I wonder if a mod he made years ago was a good one. Like most AM transmitters, it uses a choke-input PS design. I cannot recall the input choke values, but do recall that it incorporates a swinging choke and that the filter capacitor was originally quite small (2 uF, I think). that capacitor failed some time ago, and as I was looking at his documentation saw that he'd replaced it with something like 40 uF. On the list, I recall scrolling across a few postings (now lost) that said something about how these PS should be designed. There, I thought I saw something along the lines of it being possible to have too much filter capacitance. Did I get that right? If so, what's the symptom of too much filter capacitance in a choke input filter?

Re: [AMRadio] Power Supply Question
Thanks very much to everyone who responded. This is pretty much what I thought, but wasn't sure given the dynamic requirements of an AM PS. The Globe Champ seems to not have a very "stiff" supply, as I see the plate current decrease a bit under modulation instead of remain constant. I understand that this is a common characteristic of the old transmitters and that it's not anything to get wrapped around the axle about. I'm trying to interest Dad in participating in the Heavy Metal Rally on the 27th. Even though the Globe Champ is heavy, it's not 250 lbs worth, and it won't make 250 W output (275 input is the AM limit). But I bet he'd have fun! We'll see. At 81 y old, he can be a bit cantankerous at times, though he's earned every minute of cantankerosity... 73, Kim Elmore, N5OP At 05:31 PM 12/9/2003 -0600, you wrote: I wish to avail myself of the knowledge here: My Dad, W5JHJ, has a WRL Globe Champion 350 and is the original owner.

Re: [AMRadio] The PROPOSED ARRL Suggestions to FCC
I love CW; I use it almost exclusively, though I occasionally enjoy AM, along with RTTY, SSTV, MFSK16, hellschreiber, PSK31 and even -- dare I say it? -- SSB, but *I* don't think CW should be the end-all and be-all for becoming an Extra. Maybe the Eastern Block nations during the Cold War had something of merit in this regard. When I got my Extra (1970mumble, I think 1975), one had to have been licensed at least at or above above the General level (I don't think Conditional counted but I've forgotten) for at least 2 years, and had to have an Advanced license. Or something along those lines. As I understand it, in the Eastern Block countries, one had to be an SWL that collected a set number of QSL cards over a given period, on various modes, to be licensed. This displayed an "appropriate interest," etc. Some may have needed licensed sponsors. The Freedom of Information Act makes the question pools open, so we can't rely on "secret" questions. Even if we did, there would be a Bash-like industry to reveal the questions. Perhaps a minimum tenure as a licensee is a good idea? Perhaps a huge question pool, with *thousands* of possible questions is the answer? Perhaps also a tougher multiple-guess test? I dunno. But logistics decrees that bringing in a working piece of home-brew gear, or drawing schematics, or essay questions simply won't fly.

Something that demonstrated the ability of the applicant to build his own gear. Maybe an apprentice program. The only way to Extra would be through an existing Extra and building something to show that skill. This is just brainstorming, and maybe some easier way of accomplishing it could be thought of, but it seems that showing the ability to home brew is more useful AND HARDER than learning code.

To me, that would keep the integrity of the Extra above the General and somewhat meet the standards that are in place today. It seems this would placate all those of us who want that higher plane. I realize it won't be long that code requirement will be gone for good, but let's be sure the Extra test meets high standards. 73 Jim de W5JO Kim Elmore, Ph.D. University of Oklahoma Cooperative Institute for Mesoscale Meteorological Studies "All of weather is divided into three parts: Yes, No, and Maybe.

[AMRadio] WW II Army Field Sets
I'm hoping some of the old timers among you can help me with some information. I'm curious about what sorts of "portable" HF field sets were available in the Army infantry during WW II. I know of some AAF sets, and some sets used in tanks, but there seems to be little information on sets much smaller than the SCR-299 variety, which used a BC-610/Hallicrafters HT-4 as the transmitter. The SCR-299 was an entire system carried in a special communications truck. I'm looking for info about something smaller that might be carried as something to be set up within a command post. Perhaps along the lines of a Johnson Viking or Globe Champion as a transmitter and a S-40 or HQ-110 or HQ-170 as a receiver. Do any of you have info on such a beast, or know of someplace I can go to get it? I've looked quite a bit on the web and haven't yet found what I'm after.

RE: [AMRadio] WW II Army Field Sets
Wow! What a response! I don't want to buy any of the equipment. I'm curious mainly because I've decided to write a "sappy Christmas story" for QST, seeing as how I haven't seen one of those for a while. I'm not a professional writer, by any means. I author scientific papers that no one reads, of course, but with the 60th anniversary of D-Day and all, I go to thinking and decided I'd write a story about a WW-II ham in the signal corps. But, I need a portable set that can be carried in the back of jeep and lifted by a couple of guys, though not necessarily while storming a hill. Given that the BC-610 weighs in at between 400 and 600 lbs, I figured it was not a believable candidate by those who know about such stuff. I might add that getting an education about how *Army infantry* comms, especially CW, worked in WW II has been tough. There's lots of stuff about the Navy, in minute detail, but almost nothing about day-to-day Army communications. I Looking at what I've found, not much of the gear used frequencies above 12-13 MHz. There's quite a bit of VHF/UHF gear, however. The 12-30 MHz region seems to be rather sparse. I'm looking for accuracy to honor those who actually did this kind of duty and know how the equipment and protocols really worked. learned a small amount from a Brit who knew some guys that were in the British equivalent of the Signal Corps, but much else is strangely missing. I've been able to piece together some plausible protocols given what little I've been able to find on the subject. Unfortunately, I don't have easy access to the books Don Merz mentions. I should probably have them. The SCR-188 set might be a better bet for a short story, as it is completely self-contained and looks to be manageable by something less than a platoon. Depending on the variant, it used a BC-191 transmitter with a plethora of tuning units. But it doesn't appear to cover 20 m and, while I'm not certain, I'm guessing that bands were released to the hams starting at the shortest and working longer. The old 2 1/2 meter band was released about a week after VJ day, and soon after 10 m. By early 1946 almost everything, except 160 m, was available. As the story goes now, I need to use the thing by Christmas 1946 and I'm guessing that 20 m has a chance of being available by then, but not 40 m.

Re: [AMRadio] WW II Army Field Sets
Thanks for the kind words! In scientific circles, we're happy if anyone actually *uses* anything we write. It may seem odd, but we (research scientists in academic settings) live and die by publications. Yet, few of us hold any delusions about wide readership. Most who do (or have done) research will likely agree when I say that research scientists are deeply gratified if *anything* they publish finds wide utility. It's not that what we do is worthless, but for some unforeseen reason inconsequential in the research environment, research results can't be widely implemented. Man! Is this off-topic or what? Enough already! I'll bore you no more! I should have said that my characters want to be able to use the radio by Christmas *1945*, not 1946. By 1946, ham radio was back and a done deal. Honestly, I'll be amazed if anyone ever sees the story besides me and the editor who rejects it, but I'm having a lot of fun learning about this stuff. 73, Kim Elmore, N5OP At 05:02 PM 7/9/2004, you wrote: Kim: The acid rain thing back East was a Master's Thesis that no one read until one day some semi-scientist found it.

Re: [AMRadio] WW II Army Field Sets
Thanks a *bunch*! Given the st-up I've created, the SCR-188 would work FB :) So, do you (or anyone else) know what would be involved in tweaking the BC-191/BC-312 (or the JT-350A) combination to work on 20 m? Is this something a guy back then, with a bit of time, could do, or does the BC-191 design simply preclude such a conversion? I ask because the BC-191 has a plethora of "tuning units," about whose function I'm not entirely certain. I'm guessing these were exciters. If so, could one of these have been re-tuned to cover 20 m and, if *that* could be done, would the PA be able to tune 20 m? And I'm completely clueless about the BC-312 receiver, but I thought I saw (somewhere) that it could tune up to 18 MHz, which would do the trick for receive. At least these things could also do AM! Kim Elmore, N5OP At 07:48 PM 7/9/2004, you wrote: Kim, To add to all the information you've received... The HF equipment that comes closest to your requirement of "a portable set that can be carried in the back of jeep and lifted by a couple of guys," would be the SCR-284. This was a compact (for the time) unit with the transmitter and receiver in one cabinet. Could be mounted in a jeep and run off a dynamotor fed in turn with 6 or 12 vdc from the vehicle. Or, set up in the weeds and run off of a hand cranked generator. Widely used in all theaters. Low powered, though (5 watts phone, 20 watts CW), and only covered 3.8 to 5.8 mHz. The BC-1306 (mentioned by someone else) and the GRC-9 radios were successors, the latter radio arriving just at the end of the conflict. The various BC-312/BC-191 combinations (SCR-177, 188, 193, etc.) covered a wider frequency range but were much bigger and heavier. To get 160 through 20M coverage would have required the BC-610 based SCR-299, 399 and/or 499 systems for which one would need a truck (or a small room in the case of the 499). There were some other sets that come kinda close to your requirement. The JT-350A covered 1.5 - 12 mHz and put out 75 watts. This was a commercial unit the Air Corps went around the Signal corps to bootleg into service. Nice rig but hard to find.

Re: [AMRadio] WW II Army Field Sets
Ah! The perfect match! The ART-13 it will be. The basic premise of the story is that 20 m is opened for ham use before Christmas, 1944 (this is plausible, but I can't find when -- precisely -- 20 m was reopened). Through an improbable event Christmas 1943, an American signal corpsman, also a ham, and a German signalman, is also a ham, learn of each other and this changes both of their outlooks. The American subsequently volunteers for the occupation. Along the way, he and his German counterpart become friends, and the American decides to revive his (and, it turns out, the German's) tradition of Christmas Eve QSOs on the just-reopened 20 m band, simultaneously being the DX, and putting Germany back on the amateur bands, not to mention the human aspect of it all. Yes, it's a sappy, sentimental Christmas story, but I thought I'd try my hand. Thanks for all the information; this helps a lot in getting the details right. 73, Kim Elmore, N5OP P.S.: I grew up using a my Dad's (W5JHJ) rig: A J-44 hand key, an original Shure 55 microphone, a Hammarlund HQ-170A, A Hammarlund HQ-110, and a WRL Globe Champion 350.

Would be possible to strip a few turns off some of the coils to get to 20M, I guess, but the things are too unstable and drifty to be acceptable for ham use above 75M. No problem with the BC-312, though. This was the Army's general field use HF receiver of the time and it operates up to 18 mHz. Ran off 12 vdc except for a couple of later 24 volt models. The BC-342 was the 117 vac version. Does it have to be an Army field set? The Army Air Corps was using the ART-13 in their B-29s in 1944. Excellent 100W transmitter that covered 2 - 18 mHz in it's basic form. (Would actually tune down to about 1.98 mHz so covered a piece of 160M too.) Originally a Navy development. Maybe you could have your character "liberate" one of these from the flyboys, pick one out of a crashed aircraft, etc. Normally paired with the BC-348 receiver in the planes but a BC-312/342 would work along side it just fine.

Re: [AMRadio] WW II Army Field Sets
Quite right: no B-29s served in Europe because they came on line too late. In the fictional world of short stories some suspension of belief is likely, so I think there's an easy way out. In October, well after even VJ day, the supply sergeant serving our protagonist inexplicably receives a shipment of ART-13s as "surplus." Never asked for 'em, doesn't know why he got 'em, but they were duly signed for and are now his. I'd really love to use the BC-610, but I can't think of a good way to for an individual to transport it without making that short story in itself. In fact, there are many factual short stories about moving -- much less making operational -- BC-610s right here on the web :) I just sent off quick query to the Signal Corps asking about HF CW protocols during WW II. That's something that I haven't found *any* information on outside of a single blurb from the British guy about operations in Korea. Now that I've read a bit about the BC-610, I'd love to try my hand at getting one back on the air :) It looks like the SCR-399 was the ultimate Field Day set up!

The 29 was a very long ranged aircraft specifically designed to bomb Japan and all were deployed to the Pacific theater. The Navy had a shipboard adaptation of the ART-13 including a 117 vac power supply and called it the TDZ. Probably some of these kicking around in Europe at the time but we're probably getting a bit far afield now as would also be the case of salvaging an ART-13 off a Navy aircraft. Entirely possible that an event in accordance with your story line could have taken place, but the most likely equipment on the American side would have been the BC-610.

Re: [AMRadio] Somewhat Off topic - lightning protection
In cases like this "ground potential" is a relative term due to ground currents. The resistance of the ground itself can cause large potential gradients over short distances. This is exactly why it's possible to get killed by lighting without being directly hit: the potential across the distance between your feet can be more than sufficient to generate a voltage that the soles of your shoes cannot withstand. Peak currents in a cloud-to-ground strike can be exceed 50 kA on a regular basis and it doesn't take much R to get a big E with that I. The currents involved are truly mind-boggling. The advice your brother got is essentially correct: a *very* conductive grid needs to be installed all around the protected site such that large currents will not induce large voltage gradients. Copper sulfate won't do. Experimental weather radars I've seen are protected against lightning with a 00 ga copper wire mesh within the ground (3-5' deep) with many ground rods, all bonded together using thermite. A very coarse heavy-wire grid above the radar dish elevation acts as pseudo Faraday cage. Everything needs to be bonded together and then bonded to this heavy ground to be protected. Lightning protection is an expensive proposition and has to be weighed against the potential losses, but a professional analysis and installation is probably the best way to go. Kim Elmore, N5OP At 11:29 AM 7/13/2004, you wrote: This is somewhat off-topic, however the issue of lightning protection is important, and knowing how knowledgeable our members are, I thought someone might have a solution to the following problem.. My brother has a very expensive telescope in an observatory located on Petit Jean Mtn. in Arkansas. His telescope has a computerized tracking and "GoTo" system built into the base of the mount which is mounted to a steel pier. The steel pier is bolted to a 14 ton concrete substructure that is about 5 feet in the ground under the floor. The concrete section has lots of rebar and iron meshing inside of it. Lightning has taken out his computer control in the base three times in less than a year. The last two times, nothing was plugged into the unit so the base was simply at ground potential. It appears that because of the bedrock characteristics of this mountain, he is getting hit from the ground itself. I can't think of any other way. Someone emailed him the message below this morning as a possible solution, however I would be more inclined to install a tower or something a bit further to serve as a lightning rod. Maybe even treat the ground around the tower with Copper Sulfate to something similar to help give it a good ground. The suggestion below about running a copper perimeter 10' around his observatory seems like it might add to the problem. 10 feet does not sound like enough distance to be absorbing a direct hit of lightning. Since the base of the scope and the pier are both metal, there is really no way to isolate the telescope computer away from this. It is much too heavy to use nylon bolts and an insulating pad between the pier and concrete. Any ideas or suggestions? Thanks & 73, Brian / w5ami - Original Message - From: "P.

Re: [AMRadio] Pix of BPL hardware on utility poles in Cincinnati
Peter's advice is on the mark: while it is frustrating to see concerns about RFI apparently ignored in favor of the Glorious! New! Beginning! of Broadband! for the Masses! not to mention Potential Profits! Beyond the Dreams of Avarice!, we will most certainly hurt our cause if we decide to start disabling BPL equipment. We will be much more effective in the long run (because we face a strategic battle here, not a tactical one) by keeping cool heads and *relentlessly* documenting problems to our local FCC office. And we must be RELENTLESS in this action. When I lived in the Denver area, I worked at length with the FCC office there on ham-related RFI issues and always found them very supportive and very helpful. And, they were lots of fun to have beer and burgers with after a long day. Because the technology is incompatible with current spectrum users, by this strategy BPL (as it is now implemented) will most surely perish of its own accord.

RE: [AMRadio] Re: Converting old 1.8-4.0 MHz AM Marine Radios
My Dad had the First Class Radiotelephone license, before it was converted to the General. He was a bit disappointed by that restructuring, as he was quite proud of that certificate. I understand that earning it was a real bear, too. The GROL is, well, weird. I was never sure exactly what it was aimed at. It has a little bit of tube stuff in it, not much. A fair bit of digital stuff, some solid state and some basic AC circuit theory. It asked a bit about aviation instrument landing systems. Since I'm also a pilot, none of that was totally foreign. It asked a fair bit about antennas and transmission lines, though that was all very easy. I saw nothing about programming, and nothing about surface mount. The radar stuff was more fun, but still relatively basic stuff. I've done a fair bit of research with weather radars (I'm a research meteorologist), so I knew the basics of that, too. Learning more of the details was fun, though. The element for GMDSS Maintainer looks to be mainly trouble shooting and a bit more fun than the GROL, though it also contains some regulatory stuff that's unique to ships (naturally). Of course, that license certainly wouldn't be a very useful one to have in the middle of Oklahoma, unless sea level rises by about 900 ft or so...

Re: [AMRadio] Re: Converting old 1.8-4.0 MHz AM Marine Radios
Thanks Dennis! I figured that this must have been the case. I have trouble imagining what being a radio officer on a merchant ship must have been like in, say, the 70's. I've never seen any of the equipment, and I've read little about it. From what I've heard, it certainly wasn't a cushy or "romantic" job; most had additional duties beyond simply manning the radio. A few were not particularly good operators and had terrible CW skills -- it was simply a job. I've read about conditions around WWII in the QCWA Journal, and many were nothing short of horrific. Most of what I hear about is CW, but I know there had to be a fair bit of 'phone used, too, and I assume that most of that was AM for quite a while. It's hard to dig up much of the history of this after WWII, either about day-to-day operations or equipment used. Does anyone have a good source or reference? 73, Kim Elmore, N5OP At 08:11 PM 9/9/2004, you wrote: In a message dated 9/9/04 5:00:41 PM, [EMAIL PROTECTED] writes: > Now, this last part got me to wondering: were regenerative receivers made > and used commercially in shipboard service within living memory? > Oh yes, particularly in the LF/MF range.

Re: [AMRadio] AM WINDOW
Well said, John. I'm not terribly active on AM, though I've enjoyed it several times on 10 m. and I enjoy old equipment. I fired up my Dad's (W5JHJ) Globe Champ on 40 m late one afternoon and he enjoyed seeing the old rig work its magic again. As for 75 m: yep, it's a bad barrel. I find most of what I hear on the phone portion of the band shameful. That's why I usually work only CW. It's much harder for the misanthropes to be rude on CW (and the other digital modes). One of the exceptions is AM: I'm impressed with what I hear there.

Re: [AMRadio] AM WINDOW
Hi John, Well, shucks. I don't collect the stuff, but I have very fond memories of my Dad using his Globe Champ and his Hammarlund HQ-170A and HQ-100 receivers on AM. As a little kid, I loved to watch the mercury vapor rectifiers glow. Alas, he replaced them with 3B28s, which while more forgiving than the old 866As, don't make the beautiful blue glow that pulsates with modulation.

[AMRadio] Flyback Transformer for Old 'Scope
Does any one know where I might find a flyback transformer for an old Textronix 647 'scope? My Dad (W5JHJ) has one of these and the flyback transformer is bad. The 'scope works fine, except for this. When the transformer heats up, the insulation breaks down and the display dies. After a bit of cooling, everything works fine until it heats up again. He's checked with Tektronix and they have none available for such old 'scopes. He hates to junk it, but unless we can fix it, it isn't very useful and he doesn't have much interest in keeping it as a museum piece...

[AMRadio] Globe Champion 350 & HQ-170A
If all goes well and I can get enough space cleared, I'm going to set up my Dad's (W5JHJ) Globe Champion 350 and Hammarlund HQ-170A in my shack, alongside my TenTec Orion II. It has the original AX9909 finals and my Dad is the original owner (purchased in 1959!). I think he even has a spare set of finals for it. Aside for some mods my Dad has made over the years, it's original, as is the HQ-170A. The last time we fired them up, everything worked and it all tuned as it should have. This thing even has the 11 m band on the VFO scale (which, as I recall, is terribly inaccurate), though none of the 11 m components. I seldom see HQ-170As appear for sale and I can't think of the last time I saw a Globe Champ 350 for sale, so I have no idea what its value is; I'm guessing not much. Whatever it is, I assume it's higher with the AX9909's. Still, I've also seen some ideas about replacing the AX9909's with a pair of 4-65's. I can't however, find those posts anymore. Since the AX9909's are made of unobtainium, if they quit and the spares have a problem, I'll have to perform this mod. Are 4-65's more common? And, does anyone know the details of that mod? If not the 4-65, what would I use?

Re: [AMRadio] Globe Champion 350 & HQ-170A
What Kent said! Even my Dad has opined that the AX9909, while a physically pretty tube, seems to have found service only in the WRL Globe Champion. I can't find a data sheet on then, but I think they're good for something like 90 W of plate dissipation.

[AMRadio] Interesting Web Site on Early Radio
Perhaps this has been noted before and I missed it (I'm not as attentive as I should be). There's a web site that focuses on the early development of radio, up through 1927. The web address is http://earlyradiohistory.us/index.html and, while I'm not a historian, it seems comprehensive. One of the more interesting aspects are all the links to original articles and documentation. I stumbled across this while trying to uncover evidence of early (WWI) radiotelephone communications between aircraft and air-to-ground exchanges. There were some, though I haven't yet discovered what exactly was used. Could have been vacuum tubes or maybe small arc sets. I simply haven't seen what it was. Obviously, it was all AM (and all aviation voice comms remain AM to this day). I have no idea who the author is -- he may have been a ham once and was relicensed as a Novice (There's a Thomas H. White the license data base) and there is no information about him anywhere on the site. Anyway, it's a neat site.

Additionally, WWV's traditional modulation level of 50 percent for the steady tones, 50 percent for the BCD time code and 75 percent for the voice announcements was deemed "not loud enough." The station will reformulate itself as "The Tick."

Re: [AMRadio] Got an FT102
My Dad (W5JHJ SK) had one. I operated it a few times and talked him into getting it completely overhauled by NC4L (Mal Eiselman) who is a bit of a legend with these rigs. My Dad's suffered from relay problems as well as another odd-ball issue. After NC4L was done with it, it was better than new -- by quite a bit. Mal isn't cheap, but he is meticulous and does superb work. As I recall, Mal explained to me that the rx in the '102 is nearly identical in design to the original FT-1000. I don't know if that's completely accurate or not, but I recall the radio as being silky smooth and having a very nice receiver. I did listen to AM on it some and it sounded good, though I never operated the rig in AM mode. It makes a fair bit of smoke, too, with the 3 x 6146B set up. Loading it on 10 m is a bit tricky as the PA seems to have a lot of stray capacitance, so getting the load capacitance small enough can be challenging if the load isn't perfectly resistive and 50 ohms. In fact, I do recall that the PA tuning is pretty narrow: it isn't happy with an output load much different from 50 ohms resistive.

Re: [AMRadio] "My ARRL, Right or Wrong...!!!"
he amateur creed, sanctioned by the ARRL and rewarded through multiple pages of 'results'. With the phone band expansion, I simply do not believe that there is a lack of space on the bands. That some may have decided that they, by God! own a particular frequency because they've been there N decades is an argument without merit. There's plenty of space available, even on contest weekends. >From the ARRL, 'back in the day': "Considerate...never knowingly uses the air in such a way to lessen the pleasure of others." Sounds like any contesters you know? As a mater of fact, yes. All contesters that I know are quite considerate. But they also recognize that no one owns a frequency and if they happen to land on someone's favorite Sunday morning roundtable frequency, well... first come, first served. Move the roundtable! I know you enjoy stirring the pot on this subject Pete, but it's pretty clear that the ARRL lost its way some time ago and has been going downhill since. I'm unconvinced of this assertion and hold, in fact that it is in general demonstrably false. Dismissing low membership as somehow being a small piece of the pie doesn't excuse the behavior or downward spiral. Hmmm... Given that this mirrors the overall electorate (and has for most of the last 100 years) what can you deduce from it? Particularly since they're supposed to serve at the pleasure of the membership.

If the remaining 80% really wants the League to do something different, and I mean *REALLY* wants a change, they effect that change in the bat of an eye.

Besides, that would have relegated AM to an "alternative" mode and if it's an AM event you want, it needs to stand alone as AM. But there are surely historic events that could be commemorated with an AM Night. What about Fessenden's first audio transmission? Yes, I know, it's not well documented and is being challenged, it was possibly on Dec 20 and again on Dec 24th, but what of it? If not that, then how about the first "broadcast" transmission by Frank Conrad, 8XK. That was November 2, 1920. Imagine sponsorship by KDKA! You probably couldn't use that exact date, as there's no holiday associated with it, but you're a resourceful lot: improvise. There are other historical events that you could use. How about something around Sept 26, 1919, when the Director of the Naval Communications Service lifted all restrictions on radio amateurs, opening up ham radio after its ban (and near annihilation) after WWI? That would make a nice, Fall event. Or, you could simply declare an event date and do it then. Do you need an official sanction by the League? While that would be nice, it isn't a necessity. If not KDKA, maybe Electric Radio could sponsor the event; maybe some other body. The point is, ladies and gentlemen, this is yours only if you want it badly enough. 73, Kim Elmore, N5OP At 05:50 AM 4/25/2008, you wrote: On 24th April, Kim wrote: "...P.S.: You want some real fun?

Back in the early 90's, when I was still a stalwart ARRL member, I petitioned the League --- by way of letters mailed to both the Contest Advisory chairman, as well as to my regional representative on the committee --- to give consideration to incorporating AM phone in the annual "Straight Key Night" activity, as an adjunct to those Hams who either (A) were never fond of CW in the first place, or, (B) were physically unable to send code manually anymore due to age, physical disability, etc. I never received a response from ANYONE in the matter...however, some months later, there was a summary printed in QST of one of the regular general ARRL meetings which are held on a regular basis: the CAC had its input therein, alright...the notion of incorporating AM was laughingly referred in passing in it. Now, what was that you were saying again about bringing change from within...? Pretty tough nut to crack when the forces within don't listen...and no, it was NOT any "...real fun", either... ~73~ Eddy VE3CUI - VE3XZ __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body. __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

Turnout for the 2004 national election was over 60 percent according to the US Census Bureau: http://www.census.gov/prod/2006pubs/p20-556.pdf 50% or higher most of the time in national elections, far better than the ARRL (a national organization) can claim of licensed amateurs. You're right, my bad. Still, the same principle holds. When people feel their vote actually matters, they vote. How many times have you heard someone lament that 'politicians' who do whatever they want, regardless of what their constituents ask of them? Sounds a lot like the complaints about ARRL officials. Not to make too fine a point of it, but you're not a "constituent" of the ARRL because you aren't a member. Even so, you *are* a licensed ham and so what the ARRL does affects you, even if you aren't a member. And no, it's not merely a case of sour grapes as you and Pete seem to be implying. I've been told the same thing by ARRL officials as by local politicians, when asked why they clearly go against the will of the people at times: "I was elected to do what I feel is best, to use my judgement, to vote my conscience" etc, not to necessarily do what the people ask. In some sense, they're right: it's a representative organization. Although, if shown evidence of a representative going against a strong majority, I expect a darned good answer. Otherwise, that representative gets booted. > If you don't like the technical article content, write one and submit it. > TAs (technical advisors) perform the "peer review" for submissions to all > League publications.

You apparently missed this part Kim, but like many others, I'm one of the folks who got sick of banging my head against the wall so fondly known as the ARRL. No, I didn't miss it. I get that part: you don;t like the fact that, for whatever reason, the ARRL doesn't see things eye to eye with you. I did request more diversified content of my director, even volunteered to submit some myself. I was told in pretty clear terms that it is not the 'vision' the ARRL has for the future. Not that I couldn't submit it, just that I shouldn't expect to see it printed (in so many words). I'mnot going to hunt witches here, though there may be some to catch. Submit your article and let it stand or fall to the TA's peer review. That's where all the technical articles go and, believe me, there are some shining examples of the highest in our art submitted there along with some real dogs. > But, I keep hearing that "It's all those Yaecomwood ads that ruined QST." > Or the vast, rice-box conspiracy to manipulate us into appliance operating > zombies. Which is it? You're really pushing the 'straw man' to the limit here, Kim. I've not made that argument and I don't see that anyone else has. I wasn't referring to you, and I admit that wasn't clear. My point is that I see both arguments presented by various contributors and I don't see anything constructive come from either one. As AMers we welcome anyone to the mode with whatever gear they can muster. We help them to properly set up their rigs to get the most out of them in the mode. It's then up to them whether they're content with what they have or want something more or different. The highest ideal, and I do commend it. The issue of ads in QST relates more to what the magazine once was vs what it has become, tracking with the ARRL leadership's handling. This predates the perceived 'need' for a separate technical publication. My argument was, and is - with the declining amateur population and continued whining by the League in recent years about costs, income, and the rest, why produce a monthly catalog/contest results and separate technical publication along side? I can only guess that they figure the technical types will thin out enough to drop QEX and leave the glossy QST catalog as the only regular publication available to the membership. I don't believe in conspiracies and that's how this reads. Hence, I dismiss it out of hand. Bes
Re: [AMRadio] Free Mercury
This raises and interesting question: my Dad had a Globe Champion 350 and, originally, it had 866A mercury vapor rectifiers. The originals became poisoned and would arc, so he replaced them with 3B28 gas rectifiers (I think these have xenon). Many years ago, longing for that beautiful blue glow, we tried putting in a pair of what were supposed to be new (really NOS) 866As. We did all of the right stuff, letting them cook for about 30 min before applying HV, but they very soon started to act poisoned with lots of internal arcing and associated fuse-blowing. and we could never use them, so we went back to the 3B28s. Is this a typical problem with 866As? Or, is there a source of good ones that would net that retro glow? While the 3B28s are probably better all 'round rectifiers, if a good source of 866As could be had, I'd consider them should the need arise to replace the 3B28s.

Re: [AMRadio] Free Mercury
Wow! It's interesting that you should mention this: the ones I remember trying quickly started to look like there was some kind of film coming off of the anodes (they certainly didn't start that way).

Re: [AMRadio] BPL and the ARRL
This is simply an unfair assertion. It is not the ARRL's job to be the Omniscient Spectrum Protector. Most of the spectrum is not the Amateur's to protect. If the Government allows an activity that trashes its own spectrum, it's their problem, not the ARRL's. If the Government allows activity that trashes the broadcast band, it's the broadcaster's problem, not ours. Likewise the military, the FAA, and on and on. The ARRL cannot protect everyone and it is unreasonable to expect it to do so. It's primary responsibility is to promote the Amateur service. Kim Elmore, N5OP At 09:26 PM 7/18/2008, you wrote: I find it very interesting how the ARRL has changed the nature of their challenge to BPL. It started out as a worthy fight against yet another RFI problem from devices that aren't supposed to radiate. Over time their effort has "morphed" into a drive to get BPL operators to notch out the ham bands only and let the rest of the spectrum go to the dogs. I wonder why? I am against all forms of unnecessary radio noise from unlicensed devices - not just those in the ham bands. And I am a bit surprised that the League has narrowed its objective in this way. Maybe it makes it easier to declare "mission accomplished"! And, it should be noted that getting a few thousand bucks back from the FCC doesn't do anything to stop BPL.

Most of the spectrum is not the Amateur's to protect. I disagree. I asserted that the League has changed its role, and speculated on reasons that might have happened - not that the role of the ARRL should be as "Omniscient Spectrum Protector." I see the role of ARRL as representative of the membership. And my experience has been that the membership tends to be interested in the entire radio spectrum. I simply do not approve of the ARRL expending any of it's limited capacity on protecting broadcast spectrum when the broadcasters themselves are far better equipped to do that. For example, many, many of the hams that enjoy operating AM also are avid listeners to utility and broadcast stations elsewhere in the spectrum. I agree. However, it is not our responsibility to protect that spectrum. As romantic as the Golden Age of broadcasting was, the broadcasters are in it for the money, and they have a lot more of it than we do. If they want clean spectrum, they have to step up to the plate and fight BPL according to their own interests. There's nothing wrong with the ARRL, or amateurs in general, speaking up for general spectrum integrity, but our limited resources must be used for our immediate benefit. And I personally embrace the idea that the Amateur is a leader in at least the philosophies and policies of electronics and communications, and can offer guidance to all sides - a sort of liaison between the general population and the government and corporations on these subjects. You'll get no argument from me on this. The ARRL can make "amicus" -like filings in various actions (they have done this many times over the years), but when push comes to shove and real money has to be expended to protect our spectrum from poor management -- or outright abandonment -- I expect that money to be expended to specifically and explicitly protect the amateur spectrum. Indicting the ARRL because they don't take up a general fight against BPL to protect everyone's spectrum is unfair and unreasonable.
