Re: [AMRadio] 40M
Rob, I don't think that is what Jim is suggesting at all. Rather, he is likely referring to the 'dead air' groups who leave a radio running to listen for their buddies, but aren't in QSO. You can listen to the frequency for long periods with no activity. But call CQ or ask if the frequency is in use, and they jump on you. Since they see it as 'their' frequency, no one else should be using it. I don't think anyone would advocate loading up and transmitting on a frequency already in use. It's obviously a good to listen for a while since there maybe someone transmitting that you don't hear. An ongoing problem for the AMer on 40 is getting some activity going on a frequency before the busy time of night kicks in. 7.160 is as good a place as any, but only if someone is there to use it. Otherwise, find an open area and throw out a call. After the dinner hour for most of us, the band is in full swing with DX. So earlier is better. 73 - ~ Todd, KA1KAQ/4 On Mon, Sep 21, 2009 at 10:36 AM, Rob Atkinson ranchoro...@gmail.comwrote: Jim, If you want to fire up ur rig and call CQ on 7160 when there is a qso on 7161, 7158 or 7162 be my guest, it is your station not mine, but where I come from, we call people who do that lids. 73 Rob K5UJ On Sun, Sep 20, 2009 at 6:38 PM, Jim Wilhite w...@brightok.net wrote: There are people like that everywhere and if you don't hear any activity for more than a minute or two, then that is too bad.

Re: [AMRadio] 40M
You are correct Todd, that is precisely what I meant. There are several groups like this scattered around mostly in the lower part of the phone segment. I have had run ins with them not only on AM but SSB. Rod, amateur radio is not an intercom now does anyone own a frequency as Todd says. Rather it is a hobby in which all stations have rights to transmit anywhere they do not interfere with on-going communications. If I have listened for 1-5 minutes and do not hear anyone talking, the frequency is fair game. And given my AM receiver has greater bandwidth than the SSB rig, I will hear someone 1-2 Kc away. Do not let them intimidate you, I don't and they will try. Jim/W5JO - Original Message - Rob, I don't think that is what Jim is suggesting at all.

Re: [AMRadio] 40M
Just as a side note - a tip of the hat to the oft-time phenomenal band conditions that can exist on 40m in the DAYTIME hours for a good AM contact I have known 40m to produce some great S9+2-dB signals from simple 30-40 watt AM transmitters over rather short distances - say out to around 50 to 250 miles that would blow your mind. The biggest hindrance is not always the propagation, but the lack of other stations looking for a QSO. I well remember living in Maryland and working guys over in Virginia running rigs like DX40s and T-60s and they would come banging in at 20-30 dB over S-9 at around 10 or 11 a.m. on a Saturday morning. By 2 or 3 pm you couldn't even hear them at all. Or they would begin to be buried in the foreign broadcast crap. If only more people would take advantage of those conditions.

You're right - and for heavens' sakes if you say Is this frequency in use? They will come backl and say yes, and start talking with each other for a few minutes then back to their standby mode.

Re: [AMRadio] 40M
To a certain extent, the same thing has happened on 40m since (most of) the BC stations went away, as happened on 75 when the band was expanded down to 3600. Back in the spring, there was a lot of activity on 7160 at first, until the novelty wore off, and gradually the activity has dwindled. Then, there is the summertime QRN, combined with Daylight Shifting Time. In the summer months, many of us are engaging in outdoor activities until sundown, and by the time we come in the house, grab a bite to eat, and then try to play radio, we find that many of the hams on the air are already signing out to play the go to bed early/get up early routine for the next work day. And the remaining signals are often difficult to copy through all the atmospheric noise. Hopefully, things will improve as the days get shorter and better conditions in late afternoon and early evening, the QRN begins to subside, and in a few weeks we will go back to real time. A problem we may encounter as the bands get more active in the evening hours will be SSB QRM. 7285-90-95 is usually clobbered with broadcast signals during the evening hours, but 7160 is clear of broadcasting until about 0400Z when the cat and mouse game between broadcasters and white-noise jammers starts up in Ethiopia and Eritrea, often wiping out everything from 7155 to 7185. 7160 is usually excellent in the late afternoon and early evening, but it's also in prime DX territory. I remember last spring, some of the SSB DX chasers would gripe about AM operating in what they considered their exclusive playground, and of course, there was plenty of adjacent channel QRM. But this also gives us an opportunity to work Europeans on 40m phone. Earlier in the year I managed to work a few Europeans on 7160. They were on SSB, but said they could read my AM signal perfectly. A couple of these stations even switched over to AM and we had two-way transatlantic QSOs. If only some of the European group that meets on 3705 would give 7160 a try... The easiest way to grab 7160 for the evening is to start early before the activity gets heavy, call CQ if no AM is heard, and then continue the round table throughout the evening hours. So far, I haven't heard the kind of SSB jamming we are so used to on 75m. To the SSB DX chasers who gripe about AM on 7160 taking up too much of their precious DX space, my reply is that they should petition the FCC to extend the phone band down to 7100 or 7075 kHz. There is very little US CW, RTTY or data activity above 7060, and when 7075-7125 is not vacantly lying idle, it becomes filled with foreign SSB. It is totally ridiculous that the continental USA remains the only country in the world restricted from operating phone in the prime DX segment. Some die-hard CW enthusiasts want to hold on to that portion of the CW band at all costs, come hell or high water, but my response to them is use it or lose it. I rarely hear more than two or three simultaneous CW signals or QSO's in that whole 50 kHz segment. Maybe the AM community should consider submitting our own petition to the FCC, but I would suggest waiting to see just how the 40m activity pans out this season, so we could formulate something well though-out, based on real observations, not just speculation over what might be.

Re: [AMRadio] 40M
Amateurs operating in IARU Region 1 can't operate above 3.8 MHz and amateurs in IARU Region 3 can't operate above 3.9 Mhz. So, to be more consistant with the rest of the world, if you 're going to petition the FCC for more U. S. phone space on 40 meters to be more consistant with the rest of the world, you should also agree that the petition should also include removal of at least the top 100 KHz of 3.5 MHz from use by all U.

WB0W discounts it from the Heil Retail at around $299.00 The PR40 was the mic used for all the cannon shots in the movie Letter from Iwo Jima ( Spelling not correct)I have also used the EV RE10 but prefer the Heil... Good luck and if I can be of any help yell at me. Audio is my favorite part of Ham Radio...I really do not know if the KW1 will pass that low end without mods...

[AMRadio] Microphone Recommendation
In all likelihood this is probably a rehash of the Ford-Chevy-Dodge discussion; but, I do prefer the Heil PR-30/40 over the Electro-Voice RE-20/27. (Apologies to the Sennheiser and Audio-Technica devotees, I don't want to leave you out.) While the EV mics are quite good they have a few bumps and dips in the frequency response curve that, while not too severe, alter the resultant audio just enough to make it sort of bland to my ear. This may not be true for every EV RE-20/27 user but it is for me and a lot of others -- NOT what I'd expect from a mic that is as spendy as those. I really like the warmth and smoothness of the Heil PR-30/40. The sensitivity is quite good and while it does exhibit some proximity effect, for my money it is probably the best vocal/announce mic I have ever had the pleasure of using. (YMMV) I have not yet tried but was very pleased to see the PR-35 when it came out. It is a hand held version of the PR-30. The PR-40 goes the extra mile with extended frequency response (and more of studio look to it) and is an absolutely stellar performer. That and the Heil mics exceed the performance of most similar dynamic mics and some condenser mics for a lot le$$ money. Although Bob Peters, W1PE and I are good friends, and Bob Heil and I are probably friends now based on my comments about his products, I have never been paid to promote Heil microphones or received any product for my testimonials. I do however keep finding the hidden mic on the cover of Radio magazine and entering the monthly contest in hopes of winning a Heil mic only to be passed over each and every month. (sigh) This month it's a PR-40...I have my fingers crossed...maybe I can finally replace my Shure SM-7! :-) Then there's mic processing... 73 de W5SAW, Steve White Bob Peters wrote: I would say better then the RE27 PhilMore and More BC stations are buying Heil over EV...

Re: [AMRadio] 40M
Hi Todd, Well I certainly apologize to Jim for the misunderstanding, and I did forget about these dead air groups. This reminds me of once, years ago, when I asked if the frequency was in use somewhere on 75 meters and an unidentified voice said, frequency's in use. qso going on right now. I heard nothing. Then another voice, also unidentified said, There's no qso going on; go ahead and call CQ. Then the first voice, QSO going on right now. Then I said something like This is K5UJ, QRZ?QSO going on; you have to go somewhere else. Then two or three hams came out of the woodwork all saying there was no QSO and we wound up working each other and whoever it was (he never identified) had to get together with is friends somewhere else but it was explained to me that he was probably trying to reserve the frequency for some bunch coming along later. How about that. My problem is I don't get home early enough to get anything going on 40 meters before the band opens up wide. 73, Rob K5UJ On Mon, Sep 21, 2009 at 9:47 AM, Todd, KA1KAQ ka1...@gmail.com wrote: Rob, I don't think that is what Jim is suggesting at all. Rather, he is likely referring to the 'dead air' groups who leave a radio running to listen for their buddies, but aren't in QSO. You can listen to the frequency for long periods with no activity. But call CQ or ask if the frequency is in use, and they jump on you. Since they see it as 'their' frequency, no one else should be using it. I don't think anyone would advocate loading up and transmitting on a frequency already in use. It's obviously a good to listen for a while since there maybe someone transmitting that you don't hear. An ongoing problem for the AMer on 40 is getting some activity going on a frequency before the busy time of night kicks in. 7.160 is as good a place as any, but only if someone is there to use it. Otherwise, find an open area and throw out a call. After the dinner hour for most of us, the band is in full swing with DX. So earlier is better. 73 - ~ Todd, KA1KAQ/4 On Mon, Sep 21, 2009 at 10:36 AM, Rob Atkinson ranchoro...@gmail.comwrote: Jim, If you want to fire up ur rig and call CQ on 7160 when there is a qso on 7161, 7158 or 7162 be my guest, it is your station not mine, but where I come from, we call people who do that lids. 73 Rob K5UJ On Sun, Sep 20, 2009 at 6:38 PM, Jim Wilhite w...@brightok.net wrote: There are people like that everywhere and if you don't hear any activity for more than a minute or two, then that is too bad.

Re: [AMRadio] Microphone recomendation
Firstly, that's one hell of a first rig for AM! Congratulations. To me, the mic to use depends on what's been done to the KW1. Is it stock? A later KW1? It seems to me that then you would want a Hi Z communications mic. Besides what has been mentioned, there is the Shure 444 and 520. The 520 is the Green Bullet. If it's been modified for audio and can take line level low Z then you can run some processing, and a broadcast type microphone like one of the ones that has been mentioned.I think the RE20 and 27 are overpriced for ham radio; you can do real well with a Shure SM58 dynamic to a preamp and employ some equalizing and tight peak limiting ahead of the KW1. I'm afraid a broadcast or performance type mic right into the rig would sound muddy or muffled but you could always try it, what the heck, you never know for sure until you experiment. I have endured communications audio on SSB for a few years so to me, AM makes almost anything sound good, even the seemingly narrow 300-3000 Hz sounds good to me now. 73 Rob K5UJ On Mon, Sep 21, 2009 at 10:09 AM, Gerald Stockinger cliogunsm...@centurytel.net wrote: Good morning to all.

Re: [AMRadio] Microphone Recommendation
I've always had two theories as to why stations continue to purchase RE27s, one is that if you are already using 5 or 10 of them and all your processing is set up for the re27, you will be loath to throw another mic into the mix and have to accommodate it; the other is a notion true or false, that RE27s are built to take talent abuse--dropped, left out in the rainI know Bob Heil's mics are made to sound good; can anyone speak to their ability to stand up to physical abuse? One reason I don't recommend the 20 and 27 to hams is that hams probably take better care of their mics than some DJ and therefore don't need to pay an extra 200 or 300 dollars for the ruggedness.

Re: [AMRadio] Microphone Recommendation
I can answer that question...Any mic that will stand up to a Rock band like the EAGLES and being on the road tour like the Eagles do and many other groups like Frampton then it will stand up to a Jr DJ... The PR40 is used on drums all the time and in the film industry...John BXO mentioned the GoldLine dual and never using the narrow side...Then what you need to use is the PR-20... That is the SM81 changeover but again sounds better for less moneySo why spend the extra money but a PR-20... Now Steve mentioned the PR-35... That is one that I have not tried but need to...I guess guys there is another way to look at all this and here it is...EV came about for Ham Radio and owned by a Ham...That company went 100% to the Broadcast and entertainer market to Market no longer to Hams the same as Shure does... Bob Heil started as a ham is still an active ham and always will be. He looks out for the Amateur Market and always will as that is his roots and he believes in us. He and Chip and Joe Walsh are always striving to give us hams what we want and do that very well so we need to support him and his company... Can you call EV and talk to the owner NOT can you call Heil and talk to the OWNER??? Darn right... Bob will take your call answer your questions and yak about DX or Audio...

Re: [AMRadio] Microphone recomendation
Bob, As you have pointed out about other microphones, the Shure 55 Series has a VERY long and distinguished history of use under all conditions on stage. They get waved around, swung and banged on. They still keep ticking! Best with 5Meg ohm input, but will also do well as low as 1 Meg Ohm. The 5 Meg Ohm range of impedance input brings out the low end of the audio better.

Re: [AMRadio] Microphone Recommendation
I own several Shure 55S and E-V 664 and have used both quite successfully (in Hi-Z) on my BA transmitters: Apache, DX-100, and the Ranger. You have to modify the mic input circuits by raising the grid-leak resistor to at least 5 megohms or more, and change out the coupling caps. Doing those mods also makes the venerable D-104 sound excellent as well.

I welcome any suggestions on what microphone might fill my needs. Welcome to the KW-1 club, Jerry. I've had mine since 1988, pretty sure it was my first AM transmitter on the air too, otherwise the 32V gets the honor. Rob brings up a good point: where your transmitter fell in the production (first or last half, basically) will determine how it will sound with any mic. Later production units had tighter audio and require a fattening of the coupling caps along with a few other tweaks to get better audio. Later models had better plate blocking and a few other perks though, so it all evens out. Required reading IMO if you don't already have it is Electric Radio #23, March 1991. It's a special edition entirely about the KW-1 with stories from then-current owners as well as an article by Jay Bromley W5JAY (then KA5DGH) on making audio improvements to the transmitter. I did most of these mods from a sheet sent to me by Uncle Ed, WA3PUN who is a former owner. Basically, bypass the clipper and splatter choke, fatten up the coupling caps from .01s to .1s, and change the grid resistor in the 12AXY mic input circuit from the stock 1 meg to 4+ megs (Jay suggests 5M or more, but I used 4.7 and it sounds good). I didn't replace the 872s with SS sticks, but instead used 4B32s which are a drop in sub that you can find with the same glass envelope as the 872s if aesthetics are important. I've always used a crystal D-104 with excellent results, both on the KW-1 and 32V. These mods are pretty much tailored to that impedence. Another good ER issue to read on this matter is October '93 #54 I think. Gary Halverson gives an excellent explanation of mics, audio, and what's involved. Personally, I've never heard a Heil mic I liked, but I haven't heard the newer ones and it's just my opinion. As soon as you start adding processing to change characteristics, it all goes out the window IMO. Gary's article is good for this info, such as having to equalize and boost the ribbon mics and such. Nothing against processing, but if you do the simple mods to the audio of your transmitter and plug in a decent D-104 (make sure the element is in good shape with a scope), you'll be very pleased. If you want to go the processed sound route, simple feed it into the phone patch jack (you'll still have to do the other mods) and you're good to go. You can probably make a soup can sound decent with enough processing, so mic choice becomes more a choice of preference and less one of performance. ~ 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] Microphone recomendation
Earlier, in my enthusiasm for Heil mics I failed to mention (except at the end of my post) that I like and still use Shure mics. The 55S and 737A are good hi-Z mics as are the Shure 585SD, 565SD, and 545SD (all dual-Z) and the E-V 664 which was a very popular podium mic in the 60s and 70s. I have an old E-V 664 which I plan to restore and use in my ham station. It too can be wired for either hi-Z or lo-Z.

[AMRadio] Help with RME 4350 (not A)
Greetings! I recently acquired a beautiful RME 4350 (not A). It looks fantastic, but it's kind of deaf. It looks like it has been electrically restored but the previous owner sez he knows nothing (I believe him too). The sensitivity seems adequate on 160 and then goes down from there with 10 meters virtually not there at all (yes I know about band conditions, I am basing this on noise and tests with locals). The S-meter barely registers on any band and there seems to be this funny interaction between the ant trim and cal controls. I was going to try to fix this myself, but I may not be up to it as well as not having ANY decent gear should it need an alignment. So my question. Is there anyone out there that you guys could recommend to send this thing to for electrical service??

[AMRadio] Mic for KW-1
Hi Jerry, I'm looking forward to hearing you on your KW-1. A couple of questions and some advice regarding mic selection -- 1. Is the speech amp modified or stock? If it's stock, take the time to explore how to by-pass the speech clippers as a first order of business. They add a tremendous amount of distortion and ruin an otherwise decent grade of audio. 2. Do you plan to use some external audio processing ? Both these questions are important in mic selection if you're to obtain the level of audio a decent mic will offer. If you have a lot of audio energy in the lower register of your voice (bass), then you actually do NOT want a microphone that exaggerates that level of energy. You want a really bright microphone, or a flat microphone that can be tailored with the use of external equalization and compression. I'm not talking about Dog X-Ray speech processing -- but refer you to some of the used AM broadcast transmitter processors that are ideal for higher quality voice communications like we radio hobbyists enjoy. A high quality compressor will preserve your low end response, and will move other parts of the audio spectrum up in level so that you have a louder, more balanced distribution of frequency response. The chunk of voice energy, in other words, will be broader within whatever parameters your transmitter and audio chain are capable of passing. That said, you can spend $99 for a Shure SM58 and get 90 percent of the way there. It's a rugged dynamic microphone, low impedance, intended to be used with a balanced mic-line mixer, such as the $79 Behringers that seem to be everywhere. They include some blunt EQ which might be fine. You need something to bridge the high impedance, unbalanced input of the KW-1, while also having something to match the level and EQ you wish to have through a compressor.

[AMRadio] Mic recomendation for rig
Good Afternoon and thanks to all that replied and there were many. When the name Shure 55 came up I went and looked and sure enough I had one upstairs in the closet. Bob W0YVA uses one and he runs it into the phone patch jack which is 600 ohms. So that is a place to start. Many suggested the EV 664. I have one of those but it might need a new cartridge. As for a new mic many had good things to say about the Heil PR line and I might try a PR30 at some later date. To Paul VJB my rig is stock and I am looking into that. Todd my KW-1 is s/n 115 so I think that is somewhat later. Supposedly there were 150 plus two prototypes made. I have the whole set of Electric radio and will explore #23 # 54 tonight. Bob W0YVA has sent me info on jumping out the clipper and eliminating the splatter choke. I have some cap changes from him as well and I will consolidate all this info so when I do it I only have to pull the audio deck once. The last time my Doctor was inside of me he fixed three hernia's. If I create any more I will catch hell from him. He is a personal friend and saved me from Colon Cancer about two years ago and watches me like a mother hen. So one time out for the audio deck has to get everything. Again thanks to everyone that responded to my inquiry with your thoughts, suggestions, and just the spirit of camaraderie that I have enjoyed throughout my 52 years in ham radio. 73 Jerry K9GOZ __ 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.

I've had mine out a number of times doing different stages of work which could have been accomplished in one sitting with better planning. My suggestion would be to do a complete re-cap while it's out. Pay special attention to the two electrolytics clipped to one side as at least one of these is important to the audio driver bias circuit. This overall circuit is one of the few under built sections of the transmitter and deserves a bit of attention while you're at it. There are a few caps and other small components up in the RF sections, but the bulk of your problem children are in the audio deck. AES sells great Twist-Lok filter can replacements for it as well as Sprague Atom electrolyitics. Looking forward to hearing you on the air once it's ready to roll.

Re: [AMRadio] Mic recomendation for rig
Jerry, On the back of the 55S should be a switch to set for L, M, or H for impedance. There are a couple of pages for it on BAMA. Otherwise I can send them direct by E-MAIL. These settings provide for a wide range of matching possibilities. Todd and others can and I'm sure will provide the necessary info to change the audio around in your KW-1.

Re: [AMRadio] Mic recomendation for rig
Jerry, You are one hernia ahead of me hi hi; I also have to be careful lugging heavy iron, rigs etc. around. It sounds like you have a good plan and are on track. I don't think anyone here has given you bum advice but with AM and audio there is a lot of it. Todd and Paul VJB are dead on but I would work on just getting the rig running and keep it simple at first with the 55 and get used to operating it. Do the usual stuff looking at the envelope on a scope running the rig into a dummy load and listening on a seperate rx with a wide passband. Make sure ur not going over 100%, no RF in the audio, or distortion and so on. Once you are comfortable with the setup then you can start thinking about experimenting with the rig and trying some external processing if you are interested in that.You can do great with a mic preamp, dbx equalizer, compressor and a broadcast grade peak limiter. These last two can be found on eBay for not much money--old Orban blue front panel compressors show up there like the 422A and 424A and are usually overlooked by audio fanatics. These make great sounding processors for ham AM. 73 Rob K5UJ On Mon, Sep 21, 2009 at 3:08 PM, Gerald Stockinger cliogunsm...@centurytel.net wrote: Good Afternoon and thanks to all that replied and there were many.

Re: [AMRadio] 40m
Amateurs operating in IARU Region 1 can't operate above 3.8 MHz and amateurs in IARU Region 3 can't operate above 3.9 Mhz. So, to be more consistant with the rest of the world, if you 're going to petition the FCC for more U. S. phone space on 40 meters to be more consistant with the rest of the world, you should also agree that the petition should also include removal of at least the top 100 KHz of 3.5 MHz from use by all U. S. amateurs in IARU Region 2. i.e. Just to fair and consistant with many countries in the rest of the world. Of course, we have beat this dead horse several times already. Pete, wa2cwa I don't get the connection. This is Region 2, NOT Region 1 or 3. And what does 3.9-4.0 mHz have to do with it? Canada, Mexico and other Region 2 countries are all allowed to run phone below 7.125 and they still have full access to 7.2-7.3 as well as 3.9-4.0. We are unique in that we are restricted to the back of the 40m bus just because we have a lousy American licence. So give us one good reason for US amateurs being restricted form using phone on 7.100 to 7.125, or 7.075-7.100, since very few US CW or data ops use it. Hell, even US amateurs in Hawaii, Alaska, Puerto Rico, Guam and other US overseas territories have access to 7.075-7.100, but not those of us here in the lower 48.. What are the CW guys afraid of losing, since they would still be able to legally operate CW on those frequencies if they wanted to, but even now rarely operate there despite having exclusive access to it? Those who currently gripe about something being stolen from them because the phone band was expanded down to 3600 kHz can still legally operate CW on 3600-3700 but I rarely, if ever, hear any CW activity down there. Maybe there was a legitimate argument for keeping US phone activity at the high end of the band back when we had a novice band on 7.10-7.15 and hams in Regions 1 and 3 were crammed down between 7.0 and 7.1, but those days are over. There is no more novice band and 40m has been doubled in size outside of Region 2.

Re: [AMRadio] Mic recomendation for rig
The most important single accessory item to have in your AM shack is a way to monitor modulation - a cheap o'scope is a good choice. Keep an eye on it to ensure you have reasonably strong average modulation levels, and negative peaks that don't go all the way to 100% and pinch off the carrier. You current quest for a good mic is already underway. The next item I would want is a compressor-limiter. This device allows you to wander a bit from the microphone, or get excited speaking loudly, without under or overmodulating. You can get a microphone processor which combines a mic preamp with equalizer, compressor, limiter, de-esser, and such. I'm fond of the Berhinger ULTRAVOICE VX2000 for that job. They go for maybe $70 on eBay. I sometimes run more elaborate AM broadcast processors on my rigs, too... but that's because I'm a nut. The Berhinger ULTRAVOICE VX2000 alone does a great job for ham AM work. On the other hand, on my Apache I use a plain D104 driving the musical instrument (High-Z) input of a DBX 163X compressor-limiter - sounds great and very simple.

Audio Technica was briefly mentioned in the discussion of recommended microphones. Has anyone here, especially those who primarily run rice boxes, used the Audio Technica ATR30?

Re: [AMRadio] Microphone recomendation
The D-104 or any other crystal mic needs to work into PLENTY of megohms of load resistance. Astatic recommends 5 megohms, but I run mine at 10 megs - probably about as high a grid leak resistance that you can use in a tube type preamp and maintain stable operation. I have plans in the works to replace the single conductor shielded mic cord with a two-conductor one, and connect the mic up in a balanced circuit for pushpull operation, and use a pair of high-mu triodes in a push-pull mic preamp. That way, each tube can have its own 10 meg grid leak to allow for a 20 megohm load on the xtal. You can think of a crystal mic as an ideal a.c. generator with about a 500 pf capacitor wired in series. In order to get the best low-end response, the load resistance needs to be HIGH because of the high capacitive reactance in series. But there are inherent limitations to how high an input impedance you can achieve with a tube or FET input device. With the tube, if the grid leak resistance is too high, the grid will begin to hold a static charge that is not being drained off fast enough, and the bias voltage and plate current will drift around, resulting in distorted, flaky unstable output. 10 megs is about the limit. The instruction sheet that came with the earlier versions of the D-104 (the ones without the CB power mic feature) gave details on how to connect the mic up for a push-pull input stage. The stock xtal element is built as a balanced device. The unshielded bakelite case has two terminals, and either one can be used as hot or ground in the unbalanced configuration. For balanced output, connect the two wires from a two-conductor mic cord to the two terminals, and connect the shield to a ground point inside the mic head. Use a 3-connector mic plug, and at the mic preamp, let each conductor go to the grid (or gate) of one of the push-pull input devices (tube or FET), and ground the shield to chassis. The pushpull output is established by the two load resistors (grid leaks in the case of a tube pre-amp) of each amplifying device. They must be very close to equal in resistance. One end of each goes to ground. The two load resistors in series makes up the load resistor for the xtal element, and they act as a voltage divider to provide the balanced push-pull audio output for the amplifier. For a perfect match, I would recommend a pair of 10 megohm resistors, or two 5 megohm resistors in series for each, and using a DVM, match up the total resistances by adding smaller resistors series with the one with the lower resistance, until both give identical resistance readings. Besides improving the low frequency response of the mic, the balanced configuration makes it more immune to 60~ hum and rf pickup. Astatic recommends the balanced line for long mic cords more than a few feet in length.

Re: [AMRadio] Microphone recomendation
pair of high-mu triodes in a push-pull mic preamp. That way, each tube can have its own 10 meg grid leak to allow for a 20 megohm load on the xtal. It's possible to duplicate a similar circuit using an FET differential amplifier with dual FETs in a single package (e.g., 2SJ109), or a JFET-input instrumentation amp (e.g., LT1102). Both would perform best when using a bi-polar supply to economize on parts count and avoid having to use half-rail biasing technique. In each case, input Z is 2x the single-ended amp for a total of 22 meg-ohm. The circuit could be installed in the D-104 mic head, with shielded twisted-pair running to a balanced-input speech amp. Seems like there are other factors that limit the practical input Z to ~10 megohm for a crystal cartridge. The source Z and slight shunt resistance internal to the crystal cartridge may be the limiting factor. I've used a series input R of 10-meg in front of my single JFET's gate and the response is pretty much limited to about 50 Hz with or without the added R -- with the only noticeable difference being lower output level and increased noise. With the first fundamental of the deepest male voice being greater than 70 Hz, it's kinda' hard to justify a response that extends any lower for any form of voice communication, including AM and ESSB. Anything lower than 70 Hz unnecessarily increases power duty cycle and produces other unwanted artifacts like room rumble and deep breathing sounds.

Re: [AMRadio] Mic recommendation for rig
OK, Bob - I see you're a nut like me -grin- so I should describe my current set up for 160m AM. Right now my Gates BC1T has a Sennheiser 421 dynamic cardioid mic (set one click off M), feeding a Berhinger VX200 mic processor. Then it goes thru a fairly noisy Logitek rack mixer to an equalizer to let me roll the highs off to avoid being too wide, That in turn feeds a 4-band Texar Audio Prism, then a hot-rodded 3-band Dorrough DAP-310 with the second generation AM limiter card. The processors are all running pretty gently. There's picture of the audio rack on my website at the bottom of the page related to the Gates transmitter: http://www.wd8das.net/gates.html Steve WD8DAS sbjohns...@aol.com http://www.wd8das.net/ - Radio is your best entertainment value. - -Original Message- From: Bob Peters rwpet...@swbell.net To: 'Discussion of AM Radio in the Amateur Service' amradio@mailman.qth.net Sent: Mon, Sep 21, 2009 7:51 pm Subject: Re: [AMRadio] Mic recommendation for rig Steve I use a UREI BL-40 Modulimiter...and it has A symmetric as well I have a CBS Labs Limiter...and getting the CBS labs AGC as well as a pair...

This device allows you to wander a bit from the microphone, or get excited speaking loudly, without under or overmodulating. You can get a microphone processor which combines a mic preamp with equalizer, compressor, limiter, de-esser, and such. I'm fond of the Berhinger ULTRAVOICE VX2000 for that job.

Re: [AMRadio] Mic recommendation for rig
If any of you guy want it I have a schematic for a Mic Pre using a SSM 2019 Mic Preamp chip. It has a NE5523 line driver output and requires a 15 V. bipolar supply. It's real straight forward, very quiet, and you can get all the parts from Mouser or Digikey.
