Re: [AMRadio] DX 60 mods

It is a fairly clean radio inside and out, but I'm not concerened about modifying it. I would like to keep from drilling holes in the front panel but will if necesarry. I have come across 3 different audio mods on the net. They are the WC3K mod, KS3K mod, and the K4TLJ mod. In the groups opinon wich is the best one to use? Maybe it is none of the above and I should just go ahead and plate moulate it. I do have a 35 watt plat modulator that I built some time ago and it has a universal modulation transformer.

Re: [AMRadio] Painting recessed panell markings
I also had good results using a white lacquer stick on a National receiver as well as the panel and knobs of a 1924 Freed-Eismann receiver. The red lacquer stick is a perfect match for the line on Hallicrafter knobs such as the SX-99.

A white lacquer stick will do a good job filling in the depression. I used artist's paint with no thinner and a small brush to dab it into the recessed area. I wiped it off with a dry paper towel. You will not get all of it off, but after it dries, you can use a polishing compound, very fine sand paper or steel wool to remove the very small amount of excess. Then car wax to polish the entire panel. arnie - W1GCI -Original Message- From: BILL GUYGER [mailto:bguy...@sbcglobal.net] Sent: Wednesday, May 12, 2010 01:13 PM To: 'Discussion of AM Radio in the Amateur Service' Subject: Re: [AMRadio] Painting recessed panell markings Since your panel is painted this might not be good info, but on anodized panels you wipe or brush some fill paint (white enamel maybe?) over the engraved nomenclature and wipe off the excess with a rag dampened with the proper solvent for the paint you're using. I have seen engraving / machine shop people use a tooth pick to dab paint into engraved letters. When wiping off the excess it might help to use a rag that's stretched over a flat piece of plastic or wood so that your fingers aren't actually pushing the cleaning rag down into the letters / numbers and removing paint you want to remain in place. If you've painted the panel with enamel, I guess you could fill the nomenclature with Latex paint and use a rag dampened with water which shouldn't hurt the panel's finish.

Re: [AMRadio] 2m AM
To All Back in the early 80s, most of us Broadcast Engineers here in Toledo were hams (those of us left still are). We started an informal Out to lunch club. We all bought Heath Twoers and put them on the air. We would meet semi regularly but it slowed down. We had on stipulation. One could spend no more than $20 on the whole setup! most uf us found Twoers cheap as no one wanted them then (probably still don't). The antennas were wire and wood beams or if you had a Ringo Ranger up it was OK. One of us even found an unbuilt kit and finished it. His worked better than mine as I only could get about a quarter watt out. We were spread out with a radius of about 20 miles. Reception was generally OK but we eventually lost interest or some of us moved away. I still have the Twoer. Does anyone ever use these in other parts of the country?

Re: [AMRadio] Gonset 6 meter radio

It is the early one with only one xtal socket in the front I'm not sure if this is what you call a communicator or a communicator one. It is the 6 meter 12 volt version. I have a schematic for a 6 volt version but find it different in many areas. For instance the one I have uses a sub minature peanut tube a 6BG7 and a 9T8 tube in the reciever. At first I thought the 9T8 tube was a mistake but it may be used because of the filament voltage in series with the 6BG7 tube. What I could use is a good copy of a schematic for my version. I have tried BAMA but for some reason I can never down load anything from that site. I do notice they have a six meter version listed but not sure if this is the correct one. Any body got one?

One exception might be when two or more stations are xtal controlled, and some of the older VFOs do drift. But failure to zero-beat when it is easily possible and convenient is just plain sloppy operating. This is an example of the difference between necessary bandwidth and occupied bandwidth. If you are running audio out to 5 kHz, 10 kHz is the NECESSARY bandwidth of the signal. But if two stations in the QSO are 3 kHz apart, then the OCCUPIED bandwidth of the QSO becomes 13 kHz. There is no rule that says all stations in a QSO have to be on the same frequency. Hell, DX'ers routinely take up two whole SSB communications channels for one QSO by working split frequency (and these are often the very same self-righteous kilocycle kops who gripe the loudest about all that bandwidth that AM and ESSB signals take up). Nevertheless, conspicuous sloppiness about zero-beating just unnecessarily gives the slopbucketeer lunatic fringe more ammunition to use against AM. Another often-overlooked advantage of carefully zero-beating (whenever practicable) is that a breaking station attempting to enter into the QSO is less disruptive. If you can hear his audio underneath the transmitting station, and at most, the puttering sound of a nearly zero-beat carrier, this is far less disruptive to the conversation, than a loud 1-2 kHz squeal of an off-frequency carrier, which garbles up the sidebands of both signals. You often miss what the transmitting station was saying, while at the same time, missing the callsign of the breaking station. It is not unusual that breakers into a QSO are ignored for this very reason. But older transmitters with drifty VFO's are not the only problem. Some of the worst offenders are using modern transceivers on AM. Even if the audio level and carrier level are adjusted properly, so that a good, undistorted, plate-modulated quality AM signal is generated, many transceivers lack any kind of frequency spotting function. In AM mode the received signal is clearly audible as long as it lies within the transceiver's passband. So it is easy to tune in the signal on the receiver and then transmit, and end up with a carrier 1.5 kHz or more off frequency. If everyone is using a wide bandpass at the receiver and there is little congestion on nearby frequencies, this is no big deal and no-one may even notice. But if the band is crowded and many stations in the QSO are operating with the receiver in narrow bandpass, with heavy QRM off to both sides, some people in the QSO may miss the call entirely. I have seen modifications to transceivers that allow a spotting function for zero-beating purposes. Depending on the circuit design, this may be very easy with minimal alteration of the circuitry, while on others it simply isn't practical. Lacking a spotting function, the easiest method would be to put the rig in SSB/CW mode and zero-beat the AM carrier, then switch back to AM. But on some rigs, this automatically produces a frequency error, because there is a built-in frequency offset when switching between modes. In that case, you have to note the digital display frequency, and retune back to that frequency in AM mode. Even then, there may also be an offset in the digital display reading that must be taken into account. It is a matter of figuring out exactly what works

Re: [AMRadio] Tube Theremin
Steve, I have a manual for what I believe is the first commercially available Theremin made by RCA in the 1930's. It uses the same hetrodyning principal but uses some oddball transformers that would give us fits to replicate. I can try to scan the manual with schematic if you're interested. It is fascinating.

It really depends what you want out of it for performance. Nice audio, excellent selectivity, bullet-proof front end? Probably the best overall radio would be the R-390A which can be had for the top end of your price range if you shop outside ebay and don't mind doing some work to bring it up to spec. Some of the earlier Hallicrafters rigs offer nice push-pull audio output if you're seeking nice, full audio. Early Hammarlund Super Pros and some Nationals fall into the category too and can be found in the $200-$300 range. And as Ed said, the Drake gear is still some of the best gear value for performance out there. But really, pretty much any receiver with AM will work since the signal tends to be broad enough that drift isn't a big issue. It depends more on what you want for features and performance, size, weight, etc. The cheaper/low end sets just tend to be a bit morechallenging (annoying?) to use. ~ Todd, KA1KAQ/4 __ 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] 160 meter antenna
I would bet that the Skirt type antenna that you describe is actually a detuning system on a cellphone tower that is within two miles of a Directional AM Broadcast array. If the Cell tower is within the two mile range, the company who owns it must have a partial proof of performance done on the AM directional array before and after the tower is built. If it is shown to distort the pattern, then the detuning network that you see is added and tuned to make the cell tower invisible electrically to the AM array at the broadcast frequency. It actually is an untenna I guess.

Re: [AMRadio] AM on 160m
Jim, The more work you put into the antenna the better the payoff no matter what the transmitter. Truer words have never been spoken! My lot is 48X108ft. I do have a Hygain vertical and a MiniQuad that may get put back into service. I used to run QRP with the vertical on 80-10 meters with a Heath HW-8. I worked all over when conditions were fair to better. I also used the 75 meter half sloper to check in toa cw net every day. They could hear me so I guess it was oK. I'm negotiating with a friend here in Toledo to take custody of his DX-100. That should help on 75 AM. Have some splainin to do Lucy about the size of the stuff I am bringing into the house. Thanks for the advice and good conversation. Hope to meet you on the air some time. Ken --- Jim Wilhite [EMAIL PROTECTED] wrote: Hi Ken, How much space do you have? If your tower is 50-60 ft. could you possibly install an Inverted L? Say 55 ft vertical (the more the better) with the rest horizontal out to about 160-170 ft and the end as high as possible. Feed that with 50 ohm coax and use a series cap in the center of 100-300 pico farads. If you will do that, you will be able to tune the thing on all bands with a good tuner at the transmitter. The downside is that it will be a better antenna for long distant communications and not as good for distances out to 500 miles. I have 44 ft. vertical and the rest horizontal and it works on 160 both close in and at a distance (as many radials as you can put in). On 75 meters, however it is distance dependent. Close in stations are weak, stations out over 500 miles do well. As for power, the DX 40 will have trouble on 160 and 75 on AM in the evening. However on 40 and above you will make adequate contacts. On CW you will do fine on 75-10 and ok on 160. I have a 40/75 meter dipole (the poles support the ends as high as the center), the inverted L plus a 5 band beam for the upper bands. I find the L works fine on the upper bands. For transmitters I use a BW 5100B for SSB, a BW 5100 , Globe Champion 300A and a Globe King 500A. On the upper bands, power is not that important, but on 75, especially at night, it is. CW is much more forgiving than AM so take that into consideration. The more work you put into the antenna the better the payoff no matter what the transmitter. 73 Jim/W5JO - Original Message - From: Ken Zuercher Jim, If I had a little more land, I'd put up dipoles also.

RE: [AMRadio] 6V6 vs. 6L6
Not to beat a dead horse, but a 6v6 used for audio can be replaced by a 6L6. The 6L6 has a lower plate resistance so an output transformer for a pair of 6V6s will support a pair of 6L6s as the 6V6 plate resistance is about 10K per pair where the 6L6 is about 5K per pair. I have put 6L6s in many Fender guitar amps to replace the 6V6s until I could get new tubes. No problem at all. They do sound different however. (I hope I described this right) Ken Zuercher, KC8QO --- Ed Sieb [EMAIL PROTECTED] wrote: Well now...

Re: [AMRadio] 6CA7/EL34 replacements
I've had good luck with J J (tesla) tubes for output tubes, EL34 and EL84. I've had good luck with Sovtek preamp 12AX7s but not 6L6s. I use NOS that I have collected from various sources, especially hamfests. The Electro Harmonix 6L6s seem to be fine, I think that they are picked out Sovteks and the Groove Tubes 6L6s though expensive work well. I think that they are tested Sino or that they are making their own tubes now. There are new Gold Lion and Mullards now as someone is using their designs or even the original tooling. Some are reasonable in cost, some are only for audiofools with more money than sense.The Mullards are supposed to be good and not overpriced. i haven't tried them as I have some NOS units at home.

People cared more about their work back then and probably took better care in how they handled stuff. There was less pressure to just get the stuff outta here than now I'm sure. Secondly it does not matter whether so much whether you use a particular material or not, it's HOW the materials are put together that matter. Someone in a reply said it doesn't matter how it's packed if it gets dropped six feet. I think you are stating my second point from a different angle. I wouldn't send a Valiant out my door unless I felt confident... yes, confident that it could withstand a six foot drop. Probably an eight foot drop. That's not unusual and std packing procedure for a business. It's not hard to do but it takes a little work and more than that it takes thought on how it should be boxed. I've sent hundreds of items around the world. Fragile glass items. Heavy radios. I never had one damaged in transit. ALl of those packages were expected to withstand at least a six foot drop. As an example, here is what I would do with a small-medium sized transmitter: 1. Remove the tubes. They get individually wrapped in bubble-wrap and shipped separately. Any other loose pieces get sent separately in another box. If you want you can in some case wrap that stuff up and put it inside but if you want to be sure, pack it separate. 2. Depending on the tranmitter, it's value, etc I might need to make a wooden support for the transformers. 3. Wrap this up in both directions with bubble wrap. The one with the bigger bubbles, not the small-bubble kind. Tape it good. There should be at least a couple of inches of bubblewrap on every surface. 4. Using bubblewrap or high-density foam fit this assembly into a box. Not a bad idea to put it into a heavy garbage bag and tape before it goes in the box. 5. Tape this box up. Tape it up GOOD. If heavy use strapping tape as I describe below. Now this is where many people would stop. It looks like it's ready to go, right? Well many people would ship this out but it's not ready. 6. Get ANOTHER, larger box. ALlow for 3-4 inches in every direction. In between the two boxes you need some cushion. I pesonally like peanuts but if you use them they must be packed DENSELY. You want the inner box to be able to move a bit, but not much. Pack the peanuts in there tight. Tape this box up tight. Then get your strapping tape and wrap two double bands of that in each direction, each band about 25% of the way in from the edge of the box. If the box is long then I'd add two more bands in that direction. The strapping tape will prevent the box from bursting should it be dropped on a corner for instance. It's very strong stuff. You're done. Now if the transmitter is really large, or extra heavy (say 80 or 100lbs) then you need to go to the next level and crate it. Basically you follow the steps above and then put that assembly into a box that is made of plywood with reinforced corners, etc. Making a suitable crate is somewhat of an art... a story for another day. If you follow those steps listed above you will be able to drop that transmitter 6-8 feet without any damage to the box or the transmitter. It will hit with a funny dull sounds and sort of bounce (which is what you want, thats' the energy being absorbed and deflected not transferred to the transmitter). 73, Mark W1EOF SNIP Could someone explain to me how radios were shipped back in the 50's so that they arrived at the dealers with no apparent damage.

It might take a good filter on the receiver for 160 or 75 meters. How's life in Idaho? Ken Zuercher KC8QO --- [EMAIL PROTECTED] wrote: I just got a RCA BTA 5F Wow - that's a *big* old beast.

Re: [AMRadio] DX-40
Rick, I also have a Shure 444 and it sounds fine. I may start fooling around with a higher fidelity mike and a modulation monitor (from my part time broadcast engineering business) to see how good the audio can be with controlled carrier modulation. Hope to hear you on 40 meter phone. Ken, KC8QO --- Rick Brashear [EMAIL PROTECTED] wrote: Thanks Ken. The filter caps had recently been replaced, I checked them anyway and they tested fine. Replacing a couple of bypass caps seemed to do the trick. There is a little noise left, but I honestly think it's just incidental noise not an actual hum. My buddy is using a D-104 (non amplified) and it seems to be over modulating no matter chow softly you speak or how far away from the mic. Have you had any experience with that? When I operate my DX-40 I use a Shure 444 and have never had that problem. Thanks for the advice and help.

Re: [AMRadio] DX-40
Rick, I rebuilt my DX-40 a few years ago and bit the bullet. I changed the filter caps and unfortunately the power transformer. It all works fine. I would recommend just throwing awaw the filter caps as they are likely to be very old and the hum might be due to them. Good luck, i'll keep my ear out for your progress. Ken KC8QO --- Rick Brashear [EMAIL PROTECTED] wrote: A friend and I are working on his DX-40. It works beautifully with the exception of a hum (sounds more like 60 than 120 cycles to my ear) on the carrier when in phone mode whether the mic is connected or not.

Re: [AMRadio] FCC and AM on the BC band
Sorry I just got around to reading this for a reply. The prime cause of wierdness in programming and quality is that there is rarely anyone minding the store at Commercial stations, especially AM. The stations are being run by computers, Usually windows machines that are riddled with bugs. The engineers are like me, a contractor that isn't on staff and only called in ocassionally. Thing happen to the systems and you get dead air, multiple sources on the air,etc. I also think that political commentary doesn't belong on this or any other ham radio list. Considering that 90% of the AM talkers are of the right wing variety, comments about Air America should be best kept to one self. Not all of us think alike and that's a very good thing. If we did, we all would have only rice box rigs. Ken KC8QO --- VJB [EMAIL PROTECTED] wrote: The FCC is allowing the quality of AM signals to deteriorate, but it's been over a very long period of time. First there was the neglect of receiver standards which could have forced car radio and home tuner manufactuers to comply with minimum specs on selectivity and audio fidelity. Many industry observers feel this could have been established during the AM Stereo controversy. Then, after failing to do that, the FCC allowed the industry to propose and implement a 9 kHz transmitted bandwidth standard, ostensibly to minimize adjacent channel interference. In the time since digital decoding and encoding became a successor to the (sometimes) equalized metallic pair between studio and transmitter, there has not been enough industry interest at making sure digital artifacts are held to a minimum Lately, the industry jumped on the digital bandwagon that rolled through television then FM, to voluntarily try to implement In-Band, On-Channel digital service on contemporary AM frequencies. The side effects of this system spread interference well past 15 to 20 Kc from center frequency, as a function of trying to match (not beat) the kind of analog audio quality our parents remember when they were tuned to AM on the old wooden floor console that served as the Home Entertainment Center in those pre-TV days.

RE: [AMRadio] AM Power Level
Joe, When you're aligning your SX-117, check the coupling caps. I had a Hammarlund HQ-110 from the 60's that needed some coupling caps to bring the sensitivity back. Have fun!

It's become somewhat deaf over the years. Otherwise, I do not currently have another HF receiver suitable for AM. My older Kenwood transceiver is good for CW and SSB only.

Re: [AMRadio] Broadcast Transmitters
Dave, I haven't had the fun of working with Western Electric Transmitters, It would probably be the only size that would fit in my house and not cause a divorce. The 350B tubes are being used by the hi-Fi audio bunch. I think one of the tube companies are making them again. I did recently restore the Collins 20-V and had it on the air in Ann Arbor,MI. The main is a Continental Power Rock 1 KW and needed some parts. The Collins has some supporters in the Ham community. I have a friend who is a broadcast engineer in Toledo who took one out of service and plans on putting it on 75 meters. I'd love to take it home. It's construction is a work of art. I'm not looking forward to taking it out of service any time soon as it is history and sounds very good on the air. We run music on it. It is only 500 Watts and is the same cabinet etc as the 1 KW version so it is indeed a beast. Let me know how the Western Electric comes out as I'd love to hear it on the air. I will try to get on the 15 meter AM net soon. My AM rig is a Heathkit DX-40 so there is not a lot of power. It should be audible on 15 however. Ken Zuercher Chief Keeper of the Nostalgia --- David Knepper [EMAIL PROTECTED] wrote: Ken, I am presently restoring a Western Electric 250 watt transmitter, designated 451A-1. Have you ever seen one of these units. I assume that they are rather rare. This was a back up transmitter for a local radio station and was first placed in operation in 1947. I would think that anything made by Western Electric would be a collector's item. The tubes in this unit, particularly the 350B audio tubes bring big bucks. Thank you.

RE: [AMRadio] re: R 390A
Brett, This is the first I've heard about your simple superhet. Is ther more info that you'd be willing to fill me (us) in about it? I need a project for this summer. I have been considering a Regenerative tube receiver, the superhet would be better of course.Thanks in advance. Ken KC8QO --- Brett Gazdzinski [EMAIL PROTECTED] wrote: Ron, I have an r390A. Very good receiver, its a bit ugly compared to some others, but a very good design. It needs the audio taken off the diode load in the back, and put into a nice audio amp and speaker to be hi fi, as do most receivers. Used to be my favorite one to use while I was on the air, as its accurate, stable, reliable, has a scope output, nice mechanical filters, etc. I have since found out its quite noisy though, and now I notice I have a bad cap crackling someplace in the audio background. Its not a receiver you want if you jump around a lot, way too much cranking of knobs, but if you stick around one band, its great. The gears and alignment are not bad, the alignment is actually easy, the pain is when you break a gear clamp buried under a lot of other gears. Then, its a bit of like working on a transmission. My simple home brew superhetrodine blows the r390 away, better fidelity, much lower noise level, better AM filter bandwith, better frequency accuricy, easier to jump between 160, 80 and 40 meters. The r390 would be better than ANY stock rice box receiver though... Brett N2DTS Hi again... I have a chance to buy a R 390A. All those gears, etc. look imposing.

[AMRadio] Central Electronics 10A Exciter found
Hello all, Does anyone have any quick info on a Central Electronics 10A Exciter in very good condition. I found it at a local electronics store and am considering purchasing it. It has all of the parts including some plug in coils but I didn't see a manual. I have heard about the 20A but not a 10A. It has a three position switch for SB1,SB2, AM. They have it for what seems a reasonable price from a silent key. I am interested in it's AM capability of course.
