Re: [AMRadio] Schematic or Manual for National RCE Receiver
Hello - does anyone have a digital copy of the manual or a schematic for a National RCE receiver? Tnx and 73, Dave N7RK Hi Dave, I have a hard copy of the schematic at home I can scan and send you - but please give me until the weekend to do so. I also have what I believe to be an RCE (which is why I've collected the information), that I purchased at the AWA conference flea a few years ago. -Larry/NE1S -- Pay a visit to my amateur radio web page at: ne1s.rfburn.org __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] Antennas
There have been some interesting cases with short loaded antennas in the BC band, the bandwidth has occasionally been so narrow that the AM sidebands become attenuated! Not going to see that effect in the amateur bands unless someone is running an antenna only a few feet long!! Correct. This has been observed on my 75M AM mobile signal, with reports of one sideband being attenuated relative to the other.

[AMRadio] Want to Borrow Original Elmac Manuals
Hi All, Bob W9RAN has agreed to send me his original manuals for the Elmac AF-67 and AF-68. I am looking for someone or someones that have original manuals for the PMR xx and any other Elmac manuals that I may borrow to scan. I will be happy to pay postage each way and will also send the contributor or contributors a cd with all the manuals on it. My intention is to get decent scans unlike the DJvue ones currently on BAMA. No offense meant to the person that scanned them or to the DJvue format. I am mainly interested in the matching receivers for the AF-67 and AF-68 and power supplies. However if there are other Elmac manuals please let me know. I will also print a dozen of each and send to Mike N8ECR who runs the Mighty Elmac Net so he will have some on hand to give out. I will also be happy to email copies of the manuals to anyone who wishes to add them to their website.

Re: [AMRadio] Heathkit DX-60 grid current drops
As Jim says, you may be losing drive to the final grid because the drive signal is going away. But that's not all that can go wrong. Make sure the final grid bias resistor hasn't drifted off-tolerance or changing value as it heats up. If it is, replace it. I have also had bad final tubes (pair of 6146s in a DX-100) create the symptoms you describe. Originally I thought for sure the problem was with the drive signal, but that wasn't what it turned out to be. 73 es GL, -Larry/NE1S Brian the final is losing drive from the driver/buffer/VFO. Check all tubes first then if that doesn't fix it you will be troubleshooting under the chassis to find out what components may be changing value. Jim/W5JO My Heathkit DX-60 grid current drops after a couple of minutes and will keep dropping more rapidly as I increase drive level. Eventually the tube plates glow red. I am tuning by the book.

Re: [AMRadio] Request for Most Common Capacitor Values to be Reproduced
Hi Todd and All, Instead of re-inventing the wheel why don't we use one of our own who is already in the business? I refer to Tom N0JMY at Hayseed Hamfest. The name does NOT reflect the quality of his products. He is building custom electrolytics but certainly could come up with a list of common caps. Tom's a good guy with many satisified customers. I believe we should try to keep this kind of products from within if possible. 73 Lary WA9VRH - Original Message - From: Todd, KA1KAQ ka1...@gmail.com To: Discussion of AM Radio in the Amateur Service amradio@mailman.qth.net; milsurplus milsurp...@mailman.qth.net; Boatanchors boatanch...@mailman.qth.net; National Radio Equipment natio...@mailman.qth.net; Hallicrafters Reflector hallicraft...@mailman.qth.net Sent: Monday, May 03, 2010 5:31 PM Subject: [AMRadio] Request for Most Common Capacitor Values to be Reproduced Sorry for the multiple list posting, but time is short and max input is desired. Got a call from a friend this afternoon who is talking with a capacitor manufacturer about producing some caps for the radio, guitar amp, and audio crowd. We've talked about this in the past but never got to it. Now it looks like it will happen. The question is, what values would be the most handy to have supplied into the future for restoring old gear? Obviously we can't do a lot of oddball values as we're mainly looking for values that will sell well and be attractive from a production prospective. The few that popped to mind for me were: .1, .01, and .47 mfd at both 400 and 600 vdc. I also specified axial lead instead of the radial leads found on Orange drops since axial leads are better suited to our needs. I'm looking for other values that are likely to be encountered often enough to warrant production. Maybe 6-12 different values to choose from. These would be caps used for bypassing and such, not filtering. I suspect we could get them 'banded' for the foil side as well if folks feel that is important enough. The meeting is set for tomorrow, so timely input is critical. We're *not* looking for a list of manufacturers who already make caps as we believe more is better in this case. Some values are already getting difficult to find.

Re: [AMRadio] Broadcast stuff
When you think of it, what is up with ham radio, two guys trying to work each other with qsb, qrm, using expensive equipment, big antenna's, towers,etc, when you could do voice and video over the internet on a cheap laptop or an I phone...on the beach, in the den, on a train, anyplace... Four things (at least): 1. The challenge of communicating under uncertain/difficult conditions. 2. The communications systems we hams use are generally simple enough that we can understand and engineer them ourselves. It's an appropriate level of challenge - difficult enough to hold our interest, and yet not so complicated that it's impossible for an individual to accomplish. 3.

Re: [AMRadio] Low PWR FM Broadcaster
Hi Lee and all, I have a 900MHZ set of cordless headphones that I put the transmitter in the attic. Feed audio from the CCA Sunday net, DX-60 Net, CCA First Wednesday net, Mighty Elmac net, NASCAR races and other things to it. We live on 6 acres and it does a pretty good job covering most of it. May need to move the transmitter up higher on the tower from the attic but may look into a killowatt amp for the 900 MHZ. Just kidding on the KW but moving the transmitter higher would really help. It's a great way to be outdooors working and still be listening to whatever net etc.! 73 Larry WA9VRH - Original Message - From: LEE BAHR pulsa...@embarqmail.com To: Brett Gazdzinski brett.gazdzin...@verizon.net; Discussion of AM Radio in the Amateur Service amradio@mailman.qth.net Sent: Tuesday, March 16, 2010 7:11 PM Subject: [AMRadio] Low PWR FM Broadcaster I use one around here. 100mw???

Re: [AMRadio] AM IARU Region 2 Bandplan
In my opinion, the two changes that would make the most improvement to our hobby would be: 1 Cease the marginalization of the AM mode and rightly consider it another mode of phone operation that should not be limited to any sub-band or minor portion of the total phone allocation regardless of the bandwidth that it consumes. (Nobody's attacking the ESSB'ers) AND 2 Require all contests to be restricted to a portion of all bands of intended operation so as to preserve an unobstructed area of all bands for non-contesters.

Re: [AMRadio] AM IARU Region 2 Bandplan
I'll probably word it about like that. I'm in the process of getting my response together and since I'm a firm believer in call it like you see it it'll be exactly what I think. Might not make me many friends in Newington. G The ARRL seems to be pushing digital modes and contesting and leaving us AMers hanging out to dry. It's time to push back. To let them know that we will no longer permit them to marginalize us. We are simply another mode of phone operation, and entitled to the same consideration, acceptance and respect as any other mode. Without AM, there would be no other phone modes, because they're all derived from AM. SSB is simply AM with some of its parts cut off. Let's stand up for our mode, my fellow AMers. Don't just send your comments to the published email addy, but send them individually to each member of the Band Plan Committee as well. If we're going to save our mode, we have to fight for it. Let us not lose it because of apathy. Yeah, I'm an ARRL appointee, but that doesn't mean I agree with everything they do. I'll go to war to save our mode, and if they want my position over it, they're welcome to it. 73, ldb -- Larry D.

[AMRadio] CCA First Wedneday AM Night PLEASE READ SPECIAL COMMENTS! Tnx Larry
FIRST WEDNESDAY AM NIGHT!!! Sponsored by the Collins Collectors Association. Wednesday February 3rd, 2010 on 3880 kcs at 7:00 PM local East Coast time marks the start of the latest chapter of First Wednesday AM Night, drawing hundreds of vintage stations from across the country. SPECIAL COMMENT! Since band conditions have been rather unique this Fall and Winter I would ask that if one of our anchor stations is having trouble contacting stations in his area PLEASE step up to the plate and offer to help out. It does not matter where you are or how much power you are running please lend a hand. Mike who runs the Mighty Elmac net on the other Wednsday nights of the month has been doing that and he has been working stations all over the country. This is about AM activity not necessarly Collins AM activity. Please pitch in and help! Thanks! Larry WA9VRH AM Night Coordinator The East Coast and Central sections run for 90 minutes in response to the tremendous participation in those time zones. The remaining time zones will be an hour. We encourage stations to check-in on AM using Collins and other AM transmitters, new and old. It's an opportunity to revel in this nostalgic mode, enjoy giving vintage equipment a run, and sharing some storytelling about classic vacuum tube homebrew and commercial designs. Typically more than a hundred stations take part in the evening's coast-to-coast AM event; by the time it concludes at 10:00 PM Local PST. LISTEN for the following anchors and stop by to say hello, won't you? You don't have to be running Collins or vintage gear to be welcomed into the group. 7:00 PM-8:30 PM Local East Coast Time Anchor: Bob W0YVA 7:30 PM-9:00 PM Local Central Time Anchor: Jim W0NKL and Brian K0EFJ 8:00 PM-9:00 PM Local Mountain Time Anchor: K0OJ Jim and Chuck KD0ZS 8:00 PM-9:00 PM Local West Coast Time Anchor: WA6FIZ Mickey We are still looking for additional anchors in the West Coast time zone.

On sorta the same (off-) topic: Anyone know what kind of luck I might have finding some (affordable) jazz and/or blues in the old Edison 2-minute wax cylinder format, and where to look? At the AWA conference last August I bought a nice old Edison cylinder phonograph in the flea market.

Amateur radio has served the public VERY well for decades in emergency communications, and has always been on a volunteer basis. Why does this need changing now?? Are hams allowed to conduct drills on the police or fire bands? Not that I'm aware of. Why do the public service agencies need our ham frequencies now? If we allow people to be paid money for operating ham radio, we are losing the very threads the founding fathers of amateur radio and the ARRL stood for. What will be next?

[AMRadio] FIRST 2010 Collins Collectors Association First Wednesday AM Night!
HAPPY NEW YEAR ALL! Welcome to the First of the FIRST WEDNESDAY AM NIGHT 2010!!! Sponsored by the Collins Collectors Association. Wednesday January 6th on 3880 kcs at 7:00 PM local East Coast time marks the start of the latest chapter of First Wednesday AM Night, drawing hundreds of vintage stations from across the country. The East Coast and Central sections run for 90 minutes in response to the tremendous participation in those time zones. The remaining time zones will be an hour. We encourage stations to check-in on AM using Collins and other AM transmitters, new and old. It's an opportunity to revel in this nostalgic mode, enjoy giving vintage equipment a run, and sharing some storytelling about classic vacuum tube homebrew and commercial designs. Typically more than a hundred stations take part in the evening's coast-to-coast AM event; by the time it concludes at 10:00 PM Local PST. LISTEN for the following anchors and stop by to say hello, won't you? You don't have to be running Collins or vintage gear to be welcomed into the group. 7:00 PM-8:30 PM Local East Coast Time Anchor: Bob W0YVA Please note Bob will be unavailable but Roger, K5VRX will fill in for Bob (Thanks Roger!) 7:30 PM-9:00 PM Local Central Time Anchor: Jim W0NKL and Brian K0EFJ 8:00 PM-9:00 PM Local Mountain Time Anchor: K0OJ Jim and Chuck KD0ZS 8:00 PM-9:00 PM Local West Coast Time Anchor: WA6FIZ Mickey We are still looking for additional anchors in the West Coast time zone.

Re: [AMRadio] HRO question for the day
Bernie Doran wrote: National decided in the HRO50 design to use a 4.3 Ohm resister in series with the fil of both 6H6 dual diodes, ( noise blanker and detector) dropping the fil to about 5 v. In the Hro 50-1 the noise blanker 6h6 operates at normal Volts and the detector still at reduced voltage. I see no reason for this and the tube data sheets do not address lower volt operation. only effect I notice is that it takes several minutes for the detector to warm up and produce audio. It can not be for life as when this was designed and built 6h6s were cheap, still are. certainly not to save energy or battery operation. perhaps it fools the detector into something other that a square law detector due to low emission. tube life would be extended, but so what, this is not a transmitting valve and the only one I have seen where reduced voltage is recommended for standby is the 813, data recommends 8 volt when on standby and I have never done that or seen one used that way. So does anyone KNOW why national did this?I have never seen this in Collins so it must be wrong HI Bernie W8RPW Hi Bernie, This has nothing to do with your excellent question, but I thought I'd let you know I'm pretty sure I heard you last Thursday night down on 80M (not 75M) AM talking to a VE3.

Re: [AMRadio] Muting the R390 on transmit
Thanks for the reply, Grant. My R 390 doesn't mute when terminal 9 is grounded. I have connected an alligator clip lead to terminal 9 and then connected the other end of the clip lead to terminal 16 which is ground and there is no effect. I can't figure out why there is no effect when terminal 9 is grounded. What do you think, Grant? I do not have a manual or schematic for the R390. 73, John, K5PGW You didn't mention whether the Break In switch was on, which, as Grant said, must be for it (=grounding the break-in terminal) to mute the receiver. Or, maybe there is a problem in that circuit in your R390.

Not all that wide, but the descent into the stopband is pretty gentle. Very true. My R390 sounds so much better that my R390A when receiving a good-quality AM signal at any given position of the bandwidth switch appropriate for AM reception, and I've always attributed it to this. 73, -Larry/NE1S -- Pay a visit to my amateur radio web page at: ne1s.rfburn.org __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

[AMRadio] Ham mods (was Re:SP600 Question)]
Concerning the discussion of audio modifications to commercially designed amateur AM transmitters: A lot of these rigs from the 1950s (Viking I, Viking II, Valiant, DX-100) did, in fact have pretty nasty audio in their stock state, and there are good reasons to go in and engineer improvements in that department - and there are many low-hanging fruit. Granted, modifications made by hams will cover the spectrum from worse-than-stock to an extreme make-over in the positive direction. So will their physical implementation. (From what I've heard and had experience with, the Collins 32V-* series, and the Johnson Viking Ranger, are among the best-sounding in stock form of this generation of gear.) Myself, I don't like to sound raspy, distorted, or overly restricted, so I've more-or less had my way with these rigs to varying degrees here at ARS NE1S. Then again, I don't own any museum pieces, I got all of them for nothing or close to it, and could give a rats behind about any resale value. I do make sure any mods I do are neatly implemented and not ugly hack jobs, simply because that's the way I like to do things. They are my toys to enjoy, and enjoy them I do. There are two reasons I don't own any super-clean gear of this type: (1) the pricetag, and (2) I'd be reluctant to do what I consider necessary modifications to it. I'll agree with what Jim W5JO said - this type of experimentation is ham radio at its best, and I've learned a lot in the process. 73, -Larry/NE1S -- Pay a visit to my amateur radio web page at: ne1s.rfburn.org __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] AM Transmitter quality
Joe wrote: I really don't care whether people chose to modify their old AM transmitters to improve sound quality, as they can do whatever they want with their radio. What does bother me a little is when people use words like nasty and awful to describe the audio quality of some classic transmitters, as if thedesigners of the day were not smart enough to design a decent transmitter. Guilty; I used the word nasty. But in using this word I never meant to imply the engineers involved in the design were less than competent - I accept that this was the effect they were trying to achieve, perhaps in an attempt to make AM competitive with SSB to cut through the mustard. I'll still call a spade a spade though - some of them DO sound downright nasty to my ears ;-) At the time these transmitters were built, the goal of amateur pone operation was effective radiotelephone service. Human speech falls into the range between 300 and 3000 Hz. There are sounds outside this range, but they do not contribute to intelligibility. So, in order to make the best use of the power available, the bandwidth didn't need to be more than 4Khz. The next logical step in the quest for efficient use of available power was SSB, which has an equally nasty sound but does the intended job quite well. A lot of the transmitters we're talking about not only have restricted bandwidth, but are very distorted in their stock form as well, in part because of the crude hard clipping methods used to improve talk power (rather than a combination of fast AGC and hard diode clipping only on the highest audio peaks, as is employed, for example, in the CBS Volumax 410). Granted, they had a price target for the transmitter they were trying to meet, so they made the compromises they felt were necessary. I've heard it proposed that part of this may have been a marketing ploy to help the AM rigs compete in the marketplace with SSB. By modifying a transmitter to increase the audio bandwidth, all that is being done is to get it closer to the commercial broadcast transmitters of the day, which needed much greater bandwidth to handle music. Sure, but there is more to audio mods than just opening up the bandpass. There's plenty of improvements that can be made to reduce the distortion in the audio chain of the old rigs, for example, adding inverse feedback. The fact that the stock Ranger has an inverse feedback loop no doubt contributes to why it is one of the better-sounding rigs of the day.

Ken explained the FileZilla along with several other FTP programs have a tendency to worm around in an FTP server by establishing two connections and because many people try to download the entire BAMA site, SBC has prohibited it along with several other FTP programs. Clay mentioned the resident FTP part of DOS and I must confess there are so many commands in DOS that I have forgotten that I probably would die before relearning how to use it. So now I have confessed. As for Netscape-Firefox and other browsers, I have used them before but never have liked them The last time I used Firefox it locked my computer and it took a while to get it going again. So I am stuck with IE which I do fine using, and, thankfully, there are people like Jim//WB2FCN who will help a poor boy. So if you guys want to upload or download using the SBC site, be sure to read the directions. Ken mentions several things about FTP programs and the use of Windows Explorer that you should know. Ken and the host (SBC) is very kind to provide this service to us and I want to publically thank him and them. Believe me having a public and popular site like BAMA is a headache for which, they aren't paid. I scanned and sent my manual because some guys said the quality of the current one wasn't good. So if you have manuals that fit Ken's requirements, his is most accommodating and great to work with on this project. He is also a great AM person too. Thanks to all for their suggestions and help. 73 Jim/W5JO - Original Message - I use FileZilla 3.2.6.1 ( i.e., current version) and am very pleased with it. Quite capable, free, easy to use. I agree that getting all the Is dotted and the Ts crossed in the initial setup of an FTP program is the most difficult part. - Jim Tonne __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] Filament choke
One way to make an under-sized filament choke (from an inductance point-of-view) work is to parallel-resonate it at the desired frequency of operation with a capacitor. Practically, you can do this by adding the required capacitance to the input tuned circuit. On the two GG amps I built I use switched low-Q pi-nets on the input, so that meant for 160M the capacitor on the filament side of the pi-net grew in value, over what it would have otherwise been. Also works for parallel-resonant input nets, of course. I got the idea from Rich Measure's web pages; he explains it in detail there. 73, -Larry/NE1S __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

As decided by WRC-03, we get the upper part of 40 meters back this month, world-wide! It almost seems like very few want this information disseminated, I almost fell out of my chair after bringing in the latest issue of ER in from the mailbox. I thought it was NEXT year. Nothing to be found on the ARRL site, except an editorial back in 2000 proposing the return of the upper part of the band. For every two things they do right, it always seems they develop a bad case of cephalo-posterioritis on something else, and a lot of the reporting is a day late and a dollar short. I then spent some time looking through AMfone.net, but they don't seem to be discussing it either. Makes me wonder if the saying about fone-only operators might be at least partially true: Without CW, its just CB. ;) And maybe they're just fine sitting on one frequency on a band that usually goes flat by 10pm. The only place I found on the net that has it straight and out in the open is Wikipedia. http://en.wikipedia.org/wiki/40_meters I don't get it... Unless the word gets out, there'll be no one ON the upper part of 40m when it opens up! C'mon, this is a BIG deal!

Re: [AMRadio] Ultrasonic feedback
My Apache modulator squeals when the microphone gain is raised and the modulator tubes draw a lot of current. As long as the microphone gain is kept very LOW the current does not take off and there is no squeal coming from the modulator section. I am going to go through the section with a screwdriver and a nut driver to tighten up the grounds to the chassis and tube socket. In my experience the most common cause of these symptoms isn't feedback within the modulator itself, but RF rectification somewhere in the audio chain prior to the gain pot. Generally this is an indication of too much RF in the shack. I had this problem when I was using balanced line and a non-optimal tuner for this situation, creating imbalance in the system and subsequent radiation from the feedline. I have since built myself a proper balanced tuner at that operating position which has eliminated the problem. You can try wrapping the microphone cable around a ferrite or powdered iron core of the type used for RF filtering. Usually 3-4 turns will take care of it if it's going to at all. Put the core as close to the mike jack at the transmitter as you can. Trying a different style of microphone can also help. If you are running an EQ and/or processing ahead of the microphone input these devices can also be susceptible to RF rectification. 73/GL, -Larry/NE1S __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] Ultrasonic feedback
In my experience the most common cause of these symptoms isn't feedback within the modulator itself, but RF rectification somewhere in the audio chain prior to the gain pot. I also wanted to add: you can determine if this is the problem by testing the transmitter into a proper dummy load (i.e., not a light bulb, which will radiate to some degree). If the squeal goes away, or if you need to advance the audio gain considerably further for it to appear, it's probably RF rectification that's your problem. -Larry/NE1S __ 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 Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Wednesday February 4th, 2009 on 3880 kcs at 7:00 PM local East Coast time marks the start of the latest chapter of First Wednesday AM Night, drawing hundreds of vintage stations from across the country. The East Coast and Central sections run for 90 minutes in response to the tremendous participation in those time zones. The remaining time zones will be an hour. We encourage stations to check-in on AM using Collins and other AM transmitters, new and old. It's an opportunity to revel in this nostalgic mode, enjoy giving vintage equipment a run, and sharing some storytelling about classic vacuum tube homebrew and commercial designs. Typically more than a hundred stations take part in the evening's coast-to-coast AM event; by the time it concludes at 10:00 PM Local PST. LISTEN for the following anchors and stop by to say hello, won't you? You don't have to be running Collins or vintage gear to be welcomed into the group. 7:00 PM-8:30 PM Local East Coast Time Anchor: Bob W0YVA 7:30 PM-9:00 PM Local Central Time Anchor: Jim W0NKL and Brian K0EFJ 8:00 PM-9:00 PM Local Mountain Time Anchor: K0OJ Jim and Chuck KD0ZS 8:00 PM-9:00 PM Local West Coast Time Anchor: WA6FIZ Mickey We are still looking for additional anchors in the West Coast time zone.

Re: [AMRadio] The Great Rochester Hamfest
Hi All, Well you better kiss and make up or the Great Rochester Hamfest will probably be gone in a couple of years. Before you shoot me let me explain. For more years than I will put in print (in case my wife sees this) I was the chairman for the Peoria Il Superfest. For years we were on our own date. Then something happened and Radio Expo in Chicago ended up on the same weekend. We were locked into our weekend as a few years eariler the fairgrounds moved us without telling us. Well we threw a fit and they agreed NEVER to change our date again. (which they have lived up to) So for a number of years we butted heads with R.E. However even though Peoria is much smaller in population we still maintained most of our attendance. R.E. did ok also but we both had issues with dealers that wanted to be at both but did not have enough staff to do both. Well finally last year or the year before R.E. changed facilities and we are on different dates. We in Peoria have seen a growth in attendance even though hamfests in general are shrinking. We believe that both RE and Peoria will continue to prosper without the conflict of the same dates. So GUYS and GALS knock off the BS and kiss and make up before the Great Rochester hamfest becomes nothing more than memories! Neither of you will win in this pissing contest (technical term) You will tear friendships apart, you will make dealers make choices that they don't want to make (and they may not show up at either show) NO one is going to win. ESPECIALLY when you are in the same town! I hope for ALL you can straighten this out as we do not need another hamfest to go SK! 73 Larry WA9VRH - Original Message - From: Bruce bsugarb...@core.com To: Discussion of AM Radio in the Amateur Service amradio@mailman.qth.net Sent: Saturday, January 24, 2009 4:38 PM Subject: [AMRadio] The Great Rochester Hamfest Hello, I looked at both sites, and here is what I noticed: The New Rochester Hamfest is being put on by the Rochester Amateur Radio Association. The New Rochester Hamfest is recognized by the ARRL, listed by the ARRL as the only Rochester Hamfest on that date, and is the site of the ARRL Atlantic Division Convention. The Original Rochester Hamfest site is displaying 2008 information, with the notation that 2009 information will be given when it is Available. The Original Hamfest is on Friday and Saturday. The New Hamfest is on Saturday only. So, you could go to the Original Hamfest on Friday, and the New Hamfest on Saturday. A little history: The Rochester Hamfest was the largest hamfest in the eastern US. Before last year's Hamfest, a large part of the original fairground location was sold, and the formerly giant flea market was relocated into a much smaller space. Attendance was poor, and many hams thought that the Rochester Hamfest was finished. The move to a new location with space for a another giant flea market is a wonderful thing. Now we can once again look forward to more great Rochester Hamfests. 73, Bruce WA8TNC W2INR wrote: Well the story was not fully presented.

Re: [AMRadio] The Eagle Has Landed - The Gross Radio EagleThat Is
Lee - you seem to be describing a different Eagle. The original post (which John was replying to, and included in his reply) describes the Gross Eagle as a 1933 regenerative receiver: A 1933 Gross Radio Company Eagle regen RX, complete with all four coils and documentation. Think of a National SW-3, with a single coil rather the SW-3's two. Band coverage is 200 meters down to 15 meters. A pair of type 32 tubes, and a single 33 in the AF output. I have seen and operated that receiver, as the person who had originally made that post on the AWA reflector (Bruce, W1UJR) is a good friend of mine and lives nearby. See: http://www.w1ujr.net/bruces_bench_2008.htm Second project down the page, immediately following the snow static discussion. 73, -Larry/NE1S LEE BAHR wrote: The Eagle sold for less money then the Philmore. I also bought a 3735 Khz crystal for it from BA for 35 cents. -snip- As I recall the Eagle was available from Gross in the late 40s. I think maybe the Philmore NT-200 was a mass marketing knock-off of the Gross Eagle. They put everything in a fresh new box using fresh new parts, not surplus, including tubes and two coil forms for two bands. Philmore then advertised their kit to the Novice crowd and Gross probably said we want out and sold their remaing kits to BA. Both transmitters used a U shaped piece of aluminum for their chassis. The Power supplies were on another U shaped piece of aluminum. Both transmitters had their tuning caps and tuning lamps in the same place on the front of the U shaped chassis. The initual Novice bands were 80 and 11 meters. The first Philmore transmitters sported 80 and 11 meter coil information. -snip- I never tried operating on 15 with the Eagle.

Re: [AMRadio] 160 meter antenna
Brett wrote: Without a tuner, you can use the antenna's on receive, even on other bands, while with a tuner, if you get far from where you are tuned from, you get a lot of loss... True statement, but specifically: If the tuner is a high-pass filter, like the common T-network tuner (ultimate transmatch), frequencies lower than the resonant frequency of the system (=frequency the tuner antenna happen to be tuned to) are attenuated, and higher frequencies (up to a point) are passed with little loss. If the tuner is a low-pass filter, such as the balanced pi-network I use at one of my studios, frequencies higher than the resonant frequency of the system are attenuated, and lower frequencies (again, up tho a point) work Fine Business Old Man. If the tuner is a band-pass filter - an example would be the link-coupled parallel-tuned LC network popular for tuned feeders - there is attenuation on both sides of the resonant frequency.

Re: [AMRadio] Propagation
Conditions on 160M last might were extremely poor for close-in stations. I was on for the Gray Hair Net on 1945 at 8:00PM EST. I could barely hear most stations within a 150 mile radius. Stations from 150 miles to 250 miles or so were readable but below normal strength. Stations at 400 miles or so and beyond were of normal strength, or possibly a bit stronger than normal.

[AMRadio] RE: 160m AA5 receiver to AM Xmtr project
Assuming the AA5 converted to the HF receiver still uses a 455 KHz IF, you'll be mixing the RX VFO with 455KHz to generate the TX frequency. You'll have to be careful of 455KHz harmonics (the 4th is at 1820 KHz) and other mixing products that could fall inside the band, or close enough to it so that they are not attenuated sufficiently prior to being transmitted. Mixing the TX VFO (on the TX frequency or a sub-harmonic thereof) 455KHz higher for injection at the RX doesn't work because the TX VFO is right on the RX frequency, and that will be all you'll hear! 73, -Larry/NE1S From: Theosleaper [EMAIL PROTECTED] I like this idea. Pondered about taking two AA5 receivers (both the samemodel for a physical match) modified for 160 and or 80 with the local osc of one of them feeding the second one. Then the second one has its guts changed to an Xmtr with a converter that uses the local osc of the first one as a vfo. What do you think?

Re: [AMRadio] RE: 160m AA5 receiver to AM Xmtr project
Cool! You could even arrange a mechanical bandswitch to yank out the slug or jam it back in ;-) On 75M it was probably mixing with a harmonic of the local oscillator, as the image of the broadcast band would be from 1450 KHZ - 2510 KHz (assuming the radio was designed to cover 540 - 1600 KHz and the IF is 455 KHz). The AA5 I'm planning to convert used octals too, which is why I suggested the (octal) tube lineup I did for it's next incarnation. 73, -Larry/NE1S - Original Message - From: LEE BAHR [EMAIL PROTECTED] Sent: Thu, October 30, 2008 13:01 Subject:Re: [AMRadio] RE: 160m AA5 receiver to AM Xmtr project When I was in the 6th grade, I used to take my mother's AA5 radio part constantly and then put it together again. (It used octal tubes). I read in an article about a new ferrite magnetic antenna. I ordered one from Burstein-Applebee in Kansas City. It was a small coil with an adjustable slug for resonance. I hooked it up to my AA5 radio and it worked great. better then the loop on the broadcast band. Then I discovered if I pulled the slug out of the coil, the coil was now tuned to the 75 meter ham band. Apparently the second harmonic of the AA5 oscillator was now mixing with the 75 meter phone signals and producing a 455 khz signal. It worked great! 75 meter AM stations came in loud and clear.

Re: [AMRadio] Re: GBgt; 160m AM receiver project
One project on my round-tuit list is to take an old AA5 junker, from which I robbed the IF transformers long ago, into a QRP 160M AM MOPA transmitter. I would use the local oscillator as the VFO, driving a pair of 25L6s in parallel or push-pull, with another pair of 25L6s as plate modulators. Then choose the VFO tube and low-level audio tubes such that the series combination of those heaters is in the 18 - 24V range, which, in series with the 4- 25L6s, adds up to 118 - 124V for operation directly off the line. A solid-state rectifier would be used. Heck, might even be able to double in the final for 2-band operation. This would be a nice power level for running barefoot when conditions allow, or feeding a linear amplifier for more oomph, and be a bit of a novelty rig. I would use the original AA5 chassis and cabinet. -Larry/NE1S __ 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.

Re: [AMRadio] infinite impedance detector vs diode
From: [EMAIL PROTECTED] The way I understand it, The infinite impedance detector is a device such as a tube or FET that normally draws output current unless reversed biased. The device is reversed biased to cutoff and then input signal turns it on like class B service but the input does not draw current. The output is taken from the cathode, or source in the case of a FET, in follower fashion. I am not sure how this is going to correct the slew distortion that is caused by the RF filtering and discharge rate of the output. Perhaps it is because of the follower effect of having a low Z output with no diode at the output. This may mean that the discharge is at the same rate as the charge? I've recently been working on a quasi-restoration of a National NC-156 (like the NC100XA with a 1500Kc IF and a few other differences). This particular one uses one half of a 6C8 dual triode as an infinite impedance AM detector. I don't know why they did this, as it is immediately followed with a series-diode noise limiter which I would think would introduce more distortion than a simple diode envelope detector, even when disabled (diode biased fully on). The cathode-grid terminals of the other 1/2 of the 6C8 is used for this diode. This is the 1st BA receiver crossing my bench employing an infinite impedance detector, and only some of the NC-100 variants used this circuit. Other versions used the common plate detector (triode or sharp-cutoff pentode cathode-biased to near cutoff, with the IF ripple filtered in the plate circuit and audio taken from the far-side of the filter). 73, -Larry/NE1S __ 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.

[AMRadio] New England ARRL Convention in Boxboro, MA, and the ROWH
I just got home from The ARRL New England convention in Boxboro, MA, after riding down and back with my friend Steve, KS1F (formerly K1MV). The flea market was small compared to what I remember, especially considering the perfect weather both days - not many sellers, and it didn't seem very much trading was taking place. I was able to find a 175 KHz IF transformer (I've been looking for some for years), as well as several 262 KHz IF transformers, all NIB/NOS, and an xtal in a nice round ceramic holder for 3945, which is the frequency for the Old Buzzard's Net - a daily AM net here in the Northeast. Also picked up a few assorted other parts, nothing nearly as exciting as the former and not worth listing here, but stuff that I will definitely use at some point. I also enjoyed looking at the vendor's display of the latest and greatest contemporary radio toys, but don't have the spare cash right now to indulge in any of that! I enjoyed seeing many of my friends, dinner with KS1F, WA1QIX, KA2QFX, W1IF, WA1SSJ, and a beer and an eyeball QSO with Pete, WA2CWA. This is my #1 reason for attending these things any more. A highpoint was the midnight Royal Order of the Wouff Hong (ROWH) ceremony. If you ever get a chance to attend one of these, it's not to be missed. A very well-known and active AMer from the state of Maine had a prominent role in the sacred proceedings, but I can tell you no more as I am sworn to secrecy -I may even be in mortal danger by revealing this much!. We had hoped to meet up with Bruce, W1UJR, for the ROWH ceremony - he was passing through Boxboro on his way home from the AWA conference in Rochester. But he was running late, and only arrived after the ceremony was underway, so he resumed the long drive back to Woolich, ME. I found a message from him when we got back to the room shortly after 0100, so I called him then only to find he had come, and gone. 73, -Larry/NE1S __ 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.
[AMRadio] 1500 KHz trap for NC-156, one more time...
Last night I used the NC-156 receiver, with its 1500 KHz IF, on the Gray Hair Net on 1945 KHz. With the 1500 KHz filter (parallel-resonant 1000pF and 11.25µH) in series with the antenna lead, the 1945 KHz AM signals were strapping with only a very faint beat note which varied in pitch as I tuned through them with the AM detector. With the filter shorted out, all I heard was a cacophony of broadcast signals - I could no longer hear the net! I am happy... 73, -Larry/NE1S __ 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.

Re: [AMRadio] 1500 KHz trap for NC-156
Last night I had a chance to play some more with this. Perusing the junquebox yielded a 3-section, 400pF/section broadcast band air variable and a piece of air-wound coil stock about 2 diameter and about 2.5 long, #16 tinned wire, with spacing between turns about equal to the wire diameter. The coil looked about right for an 80M tank coil for a single 807 or 6146, etc. I wired them in parallel and put the parallel combination is series with the antenna lead. MUCH better - I could still null out the 1500Kc interference, but signals a few 100KHz from 1500Kc were much stronger compare with the earlier network of 200µH in parallel with 56pF. The new component values are 1000pF (measured) and 11.26µH (calculated), which approximates a series reactance of 92 ohms inductive (ignoring the capacitor's presence) at 1.2MHz and 88 ohms capacitive at 1.8 MHz (ignoring the inductor's contribution). WBZ at 1.13MHz was, within my ability to read the S-meter of questionable calibration and with QSB, 2 S-units down with the filter in, compared to what it is with the filter shorted out. On the 80M band there is no noticeable attenuation from the filter. I can live with this; I'm calling it good and moving on. Thanks to all the helpful suggestions and comments. 73, -Larry/NE1S __ 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.
Re: [AMRadio] 1500 KHz trap for NC-156
Hi Jim, Apologies if my post was confusing. Yes, I'm attempting to reject 1500 KHz, which is the IF frequency. The receiver covers 0.3 - 1.2 MHz, and 1.7 - 17 MHz, skipping a band approximately centered about the IF frequency. Therefore, the ideal (and impossible) filter would be a brick wall stopband from 1.2 - 1.7 MHz, with zero attenuation outside of that range. I mentioned 80M only to comment that I noticed no attenuation that far removed from the filter center frequency. Yes, I wanted minimal attenuation at 160M as well. There were no signals on that band when I was playing with this last night around 7PM local time to use for reference, which is why I didn't quote attenuation for 160M. However I was hearing plenty of static crashes on 160M with and without the filter. I imagine the attenuation on 160M will be somewhat similar to what I saw at 1.13 MHZ, roughly 12 dB - nothing to write home about, and hardly optimized, but good enough considering the time and effort I care to invest in this particular project. 73/TNX, -Larry/NE1S - Original Message - From: Jim Tonne [EMAIL PROTECTED] Sent: Mon, August 11, 2008 13:33 Subject:Re: [AMRadio] 1500 KHz trap for NC-156 Larry: Let me jump in on that trap thing for just a moment.

[AMRadio] 1500 KHz trap for NC-156
Hello all, I'm working on putting an AM station together for a friend, consisting of a Viking II and NC-156, both quite cosmetically-challenged, but complete. I did a bunch of work to bring them back to operation, including significant audio improvements in the Viking. However, the IF in the NC-156 is 1500 KHz, and as you might expect there is bleed-through of broadcast stations on or near that frequency, especially on the 160M band, and especially at night, when there is sky-wave propagation there. The undesired signals are so strong that it makes operation on 160M totally impossible. I first tried a series-resonant circuit from ANT to GND, and it was totally ineffective, probably because the source impedance of the antenna is low. Then I reconfigured my L and C as a parallel resonant circuit in series with the ANT at the receiver, and I was able to totally eliminate the 1500 KHz +/- interference. But, 160M signals are highly attenuated also (although S/N, if you will, where N is the the 1500 KHz interference, is much better). Also WBZ on 1.3 MHz is very noticibly attenuated. My trap consists of a 140pf air trimmer at ~40% mesh (= ~56 pF) in parallel with 200µH. I'm thinking a higher Q circuit (more C and less L) will sharpen the peak and I'll have less attenuation 300 KHz away from the resonant frequency of the trap. Or is there a better way to eliminate the 1500 KHz QRM? 73 es Tnx, -Larry/NE1S __ 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.

Re: [AMRadio] ARRL initiative
My buddy Todd wrote: I have to agree with Walter in that many folks move to such places exactly for the reasons stated: they don't want to deal with 'unsightly' antennae or whatever else, they want their neighborhood just so, etc. Anyone who freely moves there agrees to abide by these rules when they sign the contract. This is true, but there is a deeper issue, as well, and that is the concept of property rights. If you own the property, darn it, you should be free to do anything you want to it up to the point where your actions cross over the boundary onto your neighbor's property (for example, dumping hazardous waste). It is not, IMHO, one's responsibility to preserve one's neighbor's pretty view. That said, I would never consider buying a piece of property where the contract so restricted my rights. Different story if they change the rules once you already live somewhere. History dictates that your previously-lawful use should be grandfathered. If not, then you have a gripe. Yep, that's even worse. Trying to impose one's views on another by force is no different if the HOA / zoning board does it or the ARRL. Right on, 'bro. And you always have the freedom (and responsibility, IMO) not to go there if you think it's going to be a problem for you. How about just on principle? No different than moving into a residentially-zoned area and trying to set up an industrial site. You can hope for a variance, but to expect it would be foolish. They're even good enough to let you know that in advance. Zoning laws violate property rights too, IMHO. 73, -Larry/NE1S __ 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.
