Re: [AMRadio] WTB - MURCH UT-2000A
Bob, I don't dump a rig full power into a tuner and start adjusting it. I don't own a 610 but I agree that would not be good for the 610. I have never owned one of those Murch tuners (I remember the original QST article though) so it may be true that the Murch won't handle the full output of the 610 with a lot of modulation and a long transmission. Before giving up on it, it sounds to me like what you are having difficulty with is the time it takes to find a match. You need some kind of low power signal source that is enough to get a reflected power measurement, 10 watts say, or one of those SWR analyzers. I'd tune the 610 into a dummy load like you have been doing and put the tuner and antenna on an analyzer so you have plenty of time to mess with it. If it is working okay you should be able to find a way to transform your feed line to 50 ohms if there is nothing bizarre about it and your antenna, then you can switch it off the analyzer and switch the 610 on it and fire away and see if the Murch arcs or gets hot. I do that with all my tuners here because the environmental conditions outside are always changing and affecting the antennas a bit and they are always interacting with each other and I have to mess around when I change bands and ground things or let them float (I can never remember which, it varies with the band and the antenna) so the analyzer is a must have before I start dumping power into a matching network. Sometimes I'll get a slightly false reading because the analyzer is getting some signal from something else but it gets me in the ball park and I can put about 10 w. into the tuner to hit the reflected power null. Of course none of this is any good for ops who are running around chasing dx and contesting but it is fine if you are like me and squat on one frequency for an entire evening hi hi. If none of this works, why not sell the Murch to the fellow who is looking for one and fix yourself up a big L network if you are using coax feedline. Get yourself an aluminum box, a few 30 KV doorknobs, an air variable cap like an amp load cap, roller inductor and a ceramic switch for the doorknobs. With a little wiring and testing it will probably sit there and handle the 610 all day. I did something like that but I used banana plugs and jacks and jumpers and left it open because I don't have kids or pets. 73 Rob K5UJ On Sat, Jun 12, 2010 at 5:22 PM, rbethman rbeth...@comcast.net wrote: I don't care if Marconi himself designed it.

Re: [AMRadio] The Art of Ragchewing
Brian, don't be too quick to dump the Harris rig. There are probably a lot of parts in it you can use. Of course if it is working and taking a lot of space you may be better off selling it intact to a bc station looking for a back up rig. If AM QSOs are slower it is probably because of the carrier. With SSB there is no carrier so operators tend to jabber back and forth. The carrier does a number of useful things; one of these is to hold the frequency while you pause to begin a new topic or whatever. There was one time I even stopped talking in a QSO to go get a schematic upstairs--I needed it to give a guy I was working an answer to a question and I knew exactly where it was so I told him I'd be back in a minute and I got up and went and got the schematic and left the rig transmitting 300 w. and came back and picked up where I left off. I knew that was better than turning the QSO over to him, then he'd go on and it might be half an hour before we'd get back to his question if ever. Without a carrier I could not have done that. I used to work a guy on SSB who should have been an AMer. He'd make these long transmissions with loong pauses during which he'd keep the rig in transmit. Well, on SSB most operators think he quit and it was their turn. So they'd start up. Then he would resume having never put his rig in receive. Then there would be a nice long double. If you didn't know to wait for him to formally end his transmission with a call sign, he'd get you every time. We tried to tell him on SSB what he does just doesn't work but he never could get that. I think he became inactive. If I had known at the time I would have encouraged him to take up AM. All he needed was a carrier (a nice strong one). He was a very laid back guy and would have made a great AM daytime ragchewer. 73 Rob K5UJ __ 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] The Art of Ragchewing
I don't particularly care for the fast TR type qso. I hear it mostly in big groups but even though I currently run mostly modern gear, I have to switch a couple of things and prefer longer transmissions where I have a few seconds to check the carrier level and see things settle down so I like the format in which we all take a turn amongst one or two or three stations. Yes, before we get to the art of ragchewing, the stations and band have to be able to support a ragchew QSO. I like daytime in winter on 75, night on 160 in winter and days in summer on 40 for this reason. If there is an art to ragchewing, it is only the art of conversation and that is to simply find something about the other person and ask questions and get him to talk about it while you take notes and ask more questions. We all love to talk about what we are interested in don't we? All you have to do is find that thing and let the other ham tell you about it. 73 Rob K5UJ __ 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] Soldering, Me = Yes! Building, soldering and wiriing techniques?
I agree. I also have decided it was a mistake to eliminate the CW requirement for the license, not because it is necessary for communication (it is not) but because it is necessary to communicate with the most basic simple homebrew rig, a CW transmitter. Now, even if we teach homebrewing in the form of electronics lessons and construction skills, the builder of the most basic rig, a crystal controlled cw transmitter, will not have learned cw already from getting his license. He will have his completed project and not be able to do anything other than key a dead cw carrier and un-key it. Of course he can learn the code at that point, but wouldn't it be more fun and easier if he already had that skill ready to go? Many have said, and I also in the past, that no one wants to learn CW now with all the high-tech gadgets in our lives these days. They miss the point--it is not all about CW only, but CW in combination with learning about radio, building a basic rig as a learning experience and then using CW to communicate with it before moving on to more advanced circuits and transmitters. Dropping CW from the license test has been one more step in turning ham radio into glorified CB. I think we need to focus on learning electronics as an attraction to ham radio and bring back a Novice type HF privilege CW license because we lost the introduction to ham radio that involved building and getting on HF right away. Now we have new people starting out with 2 meter FM handy talkiies and it is not the same. I used to be in favor of dropping CW from the test until I realized all that I wrote above. 73 Rob K5UJ On Thu, Apr 8, 2010 at 7:47 AM, oldra...@comcast.net wrote: Sure I know how to solder.

Re: [AMRadio] More buzzies and hash
All they have to do is have one or two guys at the Port of Long Beach and randomly pull open container shipments where it says on the manifest that it is some consumer electronics product (television sets for example) and pull one out of a carton, and power it up with a spectrum analyzer there and if it is putting out garbage the whole shipment gets kicked back overseas.

Re: [AMRadio] sdr-iq
Hi Bernie, I have gone back and forth on the receive audio question with my rigs. I have never had a PC controlled receiver, but I have a Kenwood TS870 which is a 24 bit dsp firmware receiver. I have the 1000MP Mk V also and I agree that the stock audio is not very good. I widened the stock 6 KHz passband AM IF and tapped the AM detector and brought that signal out to an external tube push pull amp and speaker. Those two things made a vast difference on AM and it sounds like a tube boat anchor rx now. Next I get the 75A3 and fire it up and I'm not very thrilled with the audio quality. At this point the audio I get from the stock TS870 with a 14 KHz passband is almost as good as the modified Yaesu. 75A3 is worst of the three. But I tap the detector on the A3 and with a 10 KHz AM passband, put its audio out to another p.p. vintage AF amp and set of speakers. Now I prefer it over the TS870 and it is at least as good or better than the tapped and modified Yaesu.

Re: [AMRadio] speakers
Bernie, I immediately went to the ASS store here when you first posted your question (this was around 2 or 3 months ago) and bought one. I posted a report a few days later. You somehow missed it. It is probably in the archive. 73 Rob K5UJ Just wondering if any one bought the 12 speakers that American Science Surplus was selling and if so how do they sound? I found a cheap 12 Wolverine on ebay less the $50 inc shipping and was surprised at the differance over radio shack book shelves, thats on the 75A2.wondering what a full range 15 would do? any ideas? I am not an audio nut but do appreacate nice quality AM sound. I do realize on the ham bands not likely to hear much beyond 5 or 6 kc, there do appear to be some SW BC that transmit up to about 15 KC.

Part 15 needs to get current with the times. As more consumers replace their household appliances with models that incorporate RFI/EMI emitting technology, the problem will only become worse. The certification section was last re-written at time when nearly all of our major household appliances did not contain SMPS and microprocessors. Today, household appliances are exempt from Part 15 certification and problems associated with these unintentional radiators are dealt with after they generate interference to licensed services. The FCC could help itself in this matter with a rule change that includes appliances in the certification requirement. A bit of time spent on a rule change would pay great dividends in reducing their time spent on the enforcement effort.

Re: [AMRadio] Buzzies and hash all over the spectrum
I have been saying for the past six months or so that about the only solution to the appliance RFI problem is every man for himself, i.e. put up a low noise rx antenna, employ a phase shifting nulling box on receive, and forget QRP or even 100 w. Everyone has to raise the desired signal level by running legal limit. The unintended consequence of the FCC blowing off their duty to enforce RFI suppression in consumer products is simply that everyone will start running a lot more power on transmit to get over the high noise floor. If that causes more RFI _to_ part 15 devices too bad for them. FCC should have thought of this before they let big product manufacturers and vendors have their way. This QRM has to be dealt with the same way SSB QRM is dealt with--more power, bigger antennas, more audio.

Re: [AMRadio] AM IARU Region 2 Bandplan
Todd, you are correct. The ARRL has been obsessed with spectrum conservation for decades. It might have made some sense at one time. But the compulsion to make every emission as close to knife blade narrow as possible is out of touch with reality now.Not to mention that when I finish using 6, 8 or even 10 KHz for a QSO, the space doesn't go away, it is there for someone else to use, like a just vacated parking space. The ARRL makes it seem like every time a QSO takes place, the spectrum used is consumed and gone forever like oil. Now, we have fewer serious HF users. ARRL likes to trumpet that there are over 600,000 U.S. ham licenses out there but no mention is ever made of how many are SK, shack-on-a-belt VHF hams, XYLs who got tickets to make OM happy but never operate, emergency workers who never operate, people who lost interest due to obstacles such as station cost, technical problems, and lack of elmering, those who operate in the extreme background with PSK31, QRP...I estimate the number of hams in the U.S. who regularly transmit an impact signal on HF to be around 50,000. The ARRL would do well to address the reasons behind the obvious decline in HF activity. They did pretty well working on BPL but now in addition to that, they must work on more serious challenges: Antenna restrictions, and RFI from unintentional emitters that were cheaply made and imported. They must resist their pathological need to control U.S. ham radio and redirect this compulsion to targets where it will benefit the Amateur Radio Service. 73 Rob K5UJ The bigger issue to me is why there is so much effort being put into such extensive regulation of the amateur community with less and less activity on the bands. Rather than encouraging only certain types of operating modes, the focus should be on operating in general. ~ 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.

Jim, where do you get a 4D32 these days? thanx rob K5UJ Jack, First off, I have an HT-20 on the air and it does well on AM, so the problem is not generic to the transmitter design. I have not used a light bulb for a dummy antenna, at least not recently, but my average-reading watt meter does not bobble during modulation. I would expect a light bulb to get brighter during modulation, not dimmer, which is something you also know. From the list of things that Larry suggested, above, I would not think that #1 would not be a cause of this particular problem. Human voice audio is not symmetric, so you can achieve more full modulation by selecting the better phasing connection, but neither phasing connection should cause downward modulation. #5 is also not likely to be the problem if the rig has the original modulation transformer. The other suggestions are all likely causes. Another one might be a very flat (low gain, low emission) 4D32 final amplifier tube. Let me know how much final grid drive you are running and what the loaded plate current is for the final amp. The manual recommends 260 ma plate current for CW and 320 ma for phone, but I don't run any more than 200 ma for either phone or CW. 4D32's are too expensive! It also recommends 10 ma for grid current. The ARRL Handbook ratings for a 4D32 are a maximum of 240 ma for CW and 220 ma for phone, with 12 ma of grid current for the CW condition and 10 ma for phone. I can compare your operating parameters to the ones I'm running currently on my rig. Mine is tuned up on 14286 right now in anticipation of the Classic Exchange AM event on Sunday.

Re: [AMRadio] Comment from N0JEF
Jeff, You don't have a 200 watt AM rig, you have a 40 or 50 watt AM rig, 200 w. PEP. But 40 or 50 w. should be enough to be heard unless the QRM and QRN are really bad. Also keep in mind a lot of guys like me live in high noise level QTHs. If you have a dipole up at least 50 feet on 75 m. you should be heard by someone. 73 Rob K5UJ On Wed, Feb 10, 2010 at 10:49 PM, kj4...@aol.com wrote: Man - didn't mean to stir the pot THAT much. lol But thanks for the replies.

So, just as a suggestion, I'd make sure that your radio is set to produce good quality AM first. A local ham with AM receive capability could help you out.

It was never a big group per say, and quite often is was bolstered by newbies who thought they would fit in better if they acted like station XYZ and talked smack about riceboxes. One particular operator would chastise anyone who ran a D-104 on a BC transmitter for example, saying that such a rig required a microphone worthy of it, blah blah blah. The same mentality as the CW vs no code, homebrew vs commercial gear arguments really. Some attempt to feel superior to others. Fortunately they were few in numbers on a good day, and pretty much non-existent now. There are still a few that can be heard, but folks have figured them out for the most part. I think the introduction of the first Flex radio some years ago along with better Yaecomwood rigs that sounded good out of the box really put and end to the nonsense. You still find some remnants in the 'processed audio vs stock audio' discussions, but much of the elitism is gone. Run whatcha brung, process or stock, and have fun.

Re: [AMRadio] Comment from N0JEF
KJ4DJF, first, what is your name? It is always good to have a name to direct comments to. I'm interested also in finding out what your 200 w. AM transceiver is. I am not familiar with any recent ham rig that is a 200 w. transceiver but I am not closely following the new gear now. What you write about operating may be true part of the time, but if you have a signal that can be heard, most AM ops will recognize you without too much delay. Unless you have a very poor antenna, 200 w. should be pretty good copy on 75 meters. That's about what a Valiant puts out. You could find a clear frequency and call CQ. Give us a bit more information like frequencies you have tried to operate on, and what you are using for an antenna and rig. I promise people will be eager to work you. There is little or no cliquishness in AM. 73 Rob K5UJ On Wed, Feb 10, 2010 at 6:02 PM, kj4...@aol.com wrote: I read an article about AM use in the ham bands in a recent QST magazine and was intrigued.

Re: [AMRadio] QRM fron Neighbor's Security System
If this is a sign of what we can expect in the way of FCC policy (and I hope it is not) then the message I get is every man for himself and if the noise floor raises, then we have to raise our signal strength along with it in various ways such as increasing ERP and improving S/N ratio on rx. I do not intend to quietly give up and start getting into one of those weak signal low power data modes. Unfortunately the operators who loose out will be the ones running the 100 w. rigs who will be heard by fewer stations as time goes by. 73 Rob K5UJ On Fri, Jan 22, 2010 at 11:48 AM, sbjohns...@aol.com wrote: Field enforcement activity by the FCC in my field (broadcasting) is very low.

He tuned his T-368 for 375watts stating that was all he was allowed to operate at. The FCC tech instructed him to tune for max power out. They went through all the bands and found some slight audio reaching the stereo on 40M but that was it. They packed up. Told my friend that they loved all the classic radios that he had there and they thought they were cool. The tech also told him not to worry that his signal was clean and with in the parameters of his license. When my friend referred about what the mayor had threatened him with.

Re: [AMRadio] QRM fron Neighbor's Security System
You can certainly avail yourself of the FCC but before you start contacting them I would (after following through with your plan to make sure something your neighbor has, is indeed the problem) attempt to work something out with your neighbor first. I have been through the RFI dance myself on the sending and receiving ends. You must be mindful that your neighbor is happily operating his appliance oblivious to your misery so be in a calm and polite frame of mind. It can be a big help if you bring along a portable sw rx so you can stand there with it tuned to a clear 40 m. frequency and have it blast out the RFI to demonstrate what you are dealing with. Don't start going off on being a licensed station, Federal Law, Part 15 or any of that just yet. You may be surprised at how cooperative they might be -- they might even offer to disable the thing until it can be fixed. Not everyone is a crab (at least not everyone here in the midwest). It is tempting to charge in and blow a gasket when you have your operating wrecked, i know as I am dealing with that now on 75 and 160 but do your homework first and know what to do about the appliance so you have some measures ready if it does turn out to be this X10 thing. You'll have to have a plan to explain to them once you start talking to them. You can get some ideas on how to deal with this stuff from the ARRL Tech. Info. Service on their website, or call them and talk to someone there on the phone and use google to hunt for RFI information on these things. Also the RFI reflector at contesting.com has a searchable archive you can go through in case this has been dealt with in the past. ARRL has a list of hams, I think many are lawyers, who are experienced at being ombudsmen and helping you work with a 3rd party unknowingly causing you RFI. At this point if you contact FCC they will probably just tell you to do everything I am advising you to do first. I believe they consider themselves a last resort. 99% of the time, these things are resolved without them getting involved. If, unfortunately, your X10 folks are nasty then you have established a series of failed attempts at seeking a resolution and once you and maybe an intermediary have failed, and you have documented this, then you'll probably be able to get the FCC to intervene. One other thing is it's a good idea to have a RFI kit bag of common suppression items to take with you or have in your car. I have found it nice to have a bunch of ferrite snap on beads, doughnuts, and rods of various materials, usually 31, maybe 77, J or F --anything that is effective below 20 meters where I usually operate, plus some tools, flashlight, electrical tape, some extension cords, 10 and 20 foot lengths of 75 ohm coax with F males, phone line filters, and anything else you can think of for fixing a problem. People are usually a lot more agreeable once they realize they won't have to shell out any money. If a switching supply wall wart is causing grief for example, just replace it with a linear supply and add it to the cost of being a HF ham these days. 73 Rob K5UJ On Thu, Jan 21, 2010 at 9:10 PM, james.liles james.li...@comcast.net wrote: Hi Jim: May have been a coincidence that the same home started radiating a sweep that behaves like spread spectrum 7.1mc to 8.5mc at the same time that the security/control system was installed.

Re: [AMRadio] AM promo in QST
Here is what irritated me for the most part: In addition the carrier of an AM signal can make an annoying steady tone in the receiver of a station that is listening to SSB in the next channel. ...listen in SSB mode first to make sure that no one is using SSB nearby before making a call using AM. That torques me off for three or four reasons. 1. It implies that AMers must not annoy those operating SSB. Oooh, we'd better tip toe around the great exalted SSB stations. 2. It ignores the fact that most SSB ops now have auto-notch. 3. What if the AMer only has an old receiver like a SX28 and can't listen in SSB? Yes, some guys out there only have old recievers. I guess they all are supposed to run out and get a SSB rx so they can be considerate. 4. What the heck is a channel? What is this now, CB? (I am seeing more and more CB type lingo creeping into ham radio but that's another issue.)

Re: [AMRadio] You must see this.
Bob, I was referring to the tube Grommes. Saw a nice looking one in the flea at Dayton for around $90 and I stupidly took a pass, then changed my mind about 10 minutes later but by then it had gone. A couple months later in the summer I saw another one at the Six Meter Club/Antique Radio Club swapmeet in Wheaton IL near Chicago that was around $80. Now, these were fairly low powered, probably only 10 to 20 watts and mono. A buddy of mine grabbed the one at the hamfest in Wheaton. I've been coveting it ever since hi hi. Actually made a casual offer to buy it (he hasn't used it for anything yet) not too long ago. No deal. He knows it's a good one, and it is beautiful. So, keep ur eyes open, they're out there. Why do I want them? I'm no audio guy. I like the small tube amps to boost the product detector audio to drive speakers and give that tube boatanchor sound out the back of a solid state transceiver. I'm getting by perfectly well with old Heathkit 12 w. p.p. mono amps though.

Re: [AMRadio] You must see this.
Okay Bob, well the ones I found were all old, probably from the 50s, so that explains it. Still, they looked good and for ham shack purposes are probably FB. BTW, if you go on eBay and look in the category where these little tube amps are found (I forget where but if you search something like Heathkit EA-2 or Heathkit EA-3 you may find it) you'll see Bogens and Heathkits and other little class A p.p. mono and dual channel amps going for $100 to several hundred dollars before they even have any restoration work done on them, and these things turn up at hamfests for well under $100. The Heaths make great starter projects because they are simple and have the good Heathkit manuals, and are pretty easy to work on. Those old vac. tube amps were often designed to amplify photograph needle audio so they had preamps built into them using 12AX7 or some other similar tube and are just right for the low level product detector audio or can be bypassed for the higher level of a low powered receiver audio output. I imagine this is probably all old news for most of you. 73 Rob K5UJ On Tue, Jan 12, 2010 at 1:55 PM, Bob Peters rwpet...@swbell.net wrote: All I can say is WOW... That is the most unreal buy ever..

Quoting from the rules: The winner should be running a rig weighing 250 pounds or running at least 250 watts. This includes big homebrew, military, and vintage commercial ham gear, and Class-E solid-state rigs as long as they meet the qualifications. Stations running contemporary rigs on AM, including SDR-transceivers, are a welcome part of the event.

Re: [AMRadio] Speakers
The West Chicago store is on my way home from work so I stopped and got one of the 12 inch speakers and took it home. N.B. I'm not an audio expert and my ears have been corrupted by decades of static crashes. With that in mind. It looks fine, brand new. I don't have anything other than a little 2 lb postal scale but it felt like it weighed around 3 pounds. I hooked it up to one of my little Heathkit EA-2 amps. This is a 12 w. 20 w. peak mono push-pull amp pair of 6BQ5s that Heath sold in the 1950s. Couldn't remember the Z of the speaker so tried it on both 4 and 8 ohms. Sounded best on 8 ohms. The EA-2 gave plenty of power to drive it. Of course this quick test was without an enclosure for it and using clip leads. I tuned in a local broadcast station on 720 with the rx on 14 KHz passband. Full range audio, but to get the low frequencies and highs it does require more oomph in those ranges compared to a cabinet with 2 or three speakers and a crossover network. Put in a good cabinet with a zip cord to a receiver that can put out 5 or 6 watts audio and it should sound pretty good. Jerry when you get yours I'll be interested in knowing if my observation squares with yours. I don't have a cabinet to put mine in so if you do have one, reading how it sounds in a cabinet will be useful too. 73 Rob K5UJ On Wed, Dec 9, 2009 at 4:39 PM, Bernie Doran qedconsulta...@embarqmail.com wrote: Let us know, I did order some small dc gearmotors a while back and they were fine. these looked good to me but was afraid to say anything, someone would squak Bernie. - Original Message - From: Gerald Stockinger cliogunsm...@centurytel.net To: AM Radio AMRadio@mailman.qth.net Sent: Wednesday, December 09, 2009 5:24 PM Subject: [AMRadio] Speakers We will all learn in about a week.

Re: [AMRadio] deliberate encroachment
Hmm, interesting turn in this exchange. I think you are both right. I do not see a problem with stations gravitating to multiples of 5 for frequency as it seems to organize things under normal circumstances and helps insure that there is less QRM between AM stations. However, when things get tight, you have the freedom of moving around with a VFO if you have one, as necessary. Think of the band as a big dinner table in a restaurant. it starts out with everyone having equal space. but people keep showing up to eat at the table and start squeezing in. That's okay and everyone puts up with the occasional elbow going where it is not wanted but besides that everyone eats and is happy. So if the band is relatively free or your part of it is, and you have the luxury of picking a frequency to CQ on, why not pick a multiple of 5 or close to it if you have a VFO, but if someone is on 3873 say, you slide up to 3878 if there is a QSO on 3884 to 5 (not everyone zero beat). You can call it the dreaded channelized word but I think of it as being sensibly orderly. I don't like being channelized either but I don't mind this as it is voluntary and no one is taking my VFOs away from me and giving me a click stop xtal switch numbered 1-40. : ) 73 Rob K5UJ On Sat, Dec 5, 2009 at 7:24 PM, Todd, KA1KAQ ka1...@gmail.com wrote: On Sat, Dec 5, 2009 at 7:48 PM, Dave Mayfield W9WRL w...@gwltd.com wrote: Because, Some guys are rock bound.

You can say what you want the bottom line is this. the net control for the Military net should have done a better job, and no one should start a Q on 3887 the middle of the road. To do so is just not understanding what your doing. Not trying to pick a fight Dave, but I have to agree with Bernie on this one. Being rockbound is a choice and can be fun, but I'd bet it's more the exception than the rule. Sometimes the situation dictates using an odd frequency simply to give another, ongoing QSO enough space (regardless of mode). Everyone I know who operates with crystal control also has a VFO option available to use in order to participate in such conversations. Not only that, I have a lot of odd frequency crystals in the box here that were ground decades ago. Applying channelized thinking to today's bands for fone work is just too limiting. Right up there with restricting yourself to an imaginary AM Window tiny sliver of space. The same rules apply to frequencies in use regardless of whether they are even, odd, whole, or round. It's not like the bands are terribly congested these days. Expecting the vast majority to restrict their spectrum use to suit the possible few doesn't make sense either, in my opinion. But it is a hobby, and folks are free to operate what and how they choose, within the rules.

Re: [AMRadio] Open vs Closed -expanded
I agree it's good to listen but if I did a lot of that I'd never have a QSO. I usually get an hour here and there a couple times a week to operate, if the wx is okay and if nothing else is going on, so when I get everything fired up I want to make hay. It's funny about contact and break. As long as I can remember, contact was the standard way of getting recognized in a directed voice net. To me, break is a CB thing. contact is okay in a directed net; but I find it a little too formal for a ragchew roundtable--I just blurt out my call sign. 73 Rob K5UJ __ 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 75- 80 meters
Brett, Glad ur plasma qrm stays put. the stuff like that I get seems to slowly make its way up and down the band. I am having fairly good luck with one of those MFJ phase canceling boxes; it either eliminates or attenuates a lot of junk. DX Engineering makes a higher quality product that does the same thing but I think through 360 degrees (the MFJ covers a bit less range). Mine has made some qsos go from tolerable to pleasant. Noise level usually drops a few S units when its in and one of the best things is that because it is an analog device there isn't any dsp type distortion. Not an ad for MFJ but a plug for the method. Timewave may make one too. Only reason I use the MFJ is that a guy had one new in box for sale at Dayton 2 years ago for $70. 73 Rob K5UJ On Sun, Sep 27, 2009 at 12:47 PM, Brett Gazdzinski brett.gazdzin...@verizon.net wrote: I don't operate at night, but appreciate not having to tune all around the band looking for a good AM qso. 3880 is tough for me, some plasma TV interference on 3880 at nasty high levels, 3870 is clear.

Re: [AMRadio] Microphone recomendation
Well at the risk of starting another long blowout, I would like to meekly make the point that I find some justification in outboard processing for AM if will add a little punch and clarity to the sidebands and increase the average power in them. I think since AM in the U.S. is limited to about half the power it once was, this is a pale attempt to make up for that but it's better than nothing. I want to be clear that I'm not advocating the kind of distorted processing found in those RF speech processors that the contest and dx ops use with all knobs fully clockwise, but rather the gentle audio compressors and fast attack peak limiters that will slightly raise the average audio level going into the rig maintaining a very low THD. 73 Rob K5UJ __ 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] 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.

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.

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... Steve W5SAW that you see on the list here is a Broadcast engineer and now recommends Heil over EV all the time... He likes the PR-30 a lot and recommends it... Off course the price I gave was minus shock mount... That costs more on all of them...

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. 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.

Re: [AMRadio] 40M
I also check 7160 but am hesitant to start calling CQ because whenever I check it, there are SSB qsos all over it every 2 khz or so. 73 rob k5uj On Sun, Sep 20, 2009 at 6:55 AM, hdale77...@aol.com wrote: Where is the AM activity on 40M these days.
