[IRCA] THE CASE FOR A 2015 JOINT IRCA-NRC CONVENTION
Greetings. If you're tired of this subject, hit 'delete.' If you want to help ensure the ongoing camaraderie within NRC and IRCA, read on. We note that, following the Minneapolis joint convention in 2013, no one stepped forward to host a 2014 NRC show. At IRCA, John and Nancy Johnson fulfilled an earlier commitment to host the 50th in Billings; even though they had moved to Arizona. Now there are holes in two club calendars for 2015. Some tentative interest has been communicated to our club convention coordinators. It's apparent to folks who are tuned in to these matters that NRC and IRCA can successfully work together without political anguish. Every indicator in recent years is that joint efforts and cross-support works for the betterment of both clubs...while not impairing each club's individuality. If you accept that premise, then you would agree that a joint 2015 convention makes a lot of sense. That's because, IN POOLING CLUB SUPPORT WE MAKE HOSTING A CONVENTION THAT MUCH EASIER! So I would like to challenge readers of this note to put aside the idea that "it's just too much work" to host a convention. Active members of both clubs have already pledged their support, input, contributions, physical labor and organizational skills to a joint conclave of TWO CLUBS WHICH SHARE A COMMON HOBBY. My gosh...right now, if you announced an interest in hosting a joint show, you'd quickly receive offers of support. We're also talking about a joint 'task force' that could be of deep support in such an endeavor, handling scheduling, promotion/publicity, coordination and execution. All we really lack is a confirmed location and an agreeable date. The many previous hosts of the separate NRC and IRCA conventions did a great job, but lately, interest in hosting seems to be diminishing. We learned from our 2013 Minneapolis experience that doing a JOINT convention of the clubs was easier than a single-club event, since we had so much talent and support to draw from! SO, Mister or Ms. club-member: Now's the time to step forward to indicate an interest, so that you can judge for yourself whether it's something you want to do. The bottom line is that with an early convention/city selection, we can all look forward to getting together next year. Mike Sanburn and Ernie Wesolowski are great resources, possessing the knowledge of previous conventions and the specific requirements. I'd be very happy to discuss with you, off-line if you wish, what's involved in doing this...and I can relate how much satisfaction we got from the Minneapolis joint convention and its energy.

Re: [IRCA] KRKO DIGITAL
KSL puts in enough digital sideband hash to eliminate 1150 and 1170 in Minnesota at night :-)) Regards, Mark Durenberger -Original Message- From: Patrick Martin Sent: Saturday, October 04, 2014 4:24 PM To: IRCA Subject: Re: [IRCA] KRKO DIGITAL Rick, If that is the case, then I do not see an all digital happening. However, going back to the early 90s, when Bob Rusk did one of the first articles on IBOC for Radio World, I thought at the time, the FCC would never okay such a noise maker. I was wrong as many were in the industry at the time. Here, the all digital on 1380 last night did not seem to interfere with 1390 as much. The bandwidth seemed more narrow, but KRKO is not a powerhouse here, so if someone like KSL decided to go all digital it may be a difference situation. KRKO is stronger than KKXA is by far, but still no powerhouse. KIRO is the strongest Puget Sound station I receive day or night, followed by KJR. KIRO has about 86 KW aimed at me. None of the Puget Sound IBOCers are really that strong here. 1090 isn't either. My worst offender is KSL, followed by probably KFBK. KFBK is not really that listenable in analog as with the high end part of the band, night fades, often they sound like they are broadcasting from a barrel. KCBS is also IBOC, but doesn't QRN as much running most of their power South. I will try for the KKXA test tonight, but I don't feel I will have much luck, not with KGDD in the mix. KKXA is almost DX here at night. KKXA IS DX days and tough to get. KGDD sends their power to the W/NW. 73, Patrick Patrick Martin Seaside OR KGED QSL Manager From: rick...@shellworld.net To: irca@hard-core-dx.com Date: Sat, 4 Oct 2014 10:41:39 -0700 Subject: Re: [IRCA] KRKO DIGITAL Hi Pete and All, 1370 is covered in noise, and 1360 is more affected by the noise than in hybrid HD mode. I believe I'm about 30 miles from the transmitter. In this test I don't know what they've done and what they haven't done. No question about it; KRKO wasn't decoding before the test; they are now. As expected, their HD coverage is better. But the bit rate isn't better, so the audio is swishy and unpleasant. The highs are artificial, and the audio is fatiguing. On average, the Sony takes about four seconds to decode the signal versus about eight seconds in hybrid mode. HD proponents would undoubtedly consider this a success. As a listener, even putting my DX preferences aside, I expected better. I wouldn't listen to audio like this on a PC, and I certainly wouldn't do it on a radio. Standard AM sounds better. It may have fewer highs, (and I love hearing high frequencies!), but it's easier on the ears. -- Rick -Original Message- From: IRCA [mailto:irca-boun...@hard-core-dx.com] On Behalf Of Pete Taylor Sent: Saturday, October 04, 2014 10:11 AM To: IRCA of America Subject: [IRCA] KRKO DIGITAL I tuned in to KRKO-1380 about 10:03 PDT this morning and it was operating in normal analog.

The same reception pattern holds true for the domestic Aussie broadcasters in the 120 meter shortwave band. They always come in better on the North D-KAZ.

Things only got better from that point when I heard two Aussie accented ladies talking about the music between each song selection, and finally catching this announcement from one of them: "you're listening to ABC Local Radio".

Re: [IRCA] New antenna report
Thanks Brian. Read your report just as we're preparing for "Selfish Birthday Trip 2015" which includes a follow-on DXPedition to the Eastern Utah desert. This year we plan comparison tests among several antennas of various sizes including a D-Kaz (single and broadside), a decent-sized EWE and a Super-Loop...as well as a horizontal MW loop. The desert is a good place to spread these far enough apart to avoid mutual interference Most of our work however will be in daylight, since we need good ground-wave signals for reliable measurements. But at some point we'll chase the Sunset toward the Pacific Northwest, in the hopes of catching some stations still on day power 'up there' while the stations on the way are dropping to post-sunset power. I'll be posting the results...and will be eagerly watching your own success! Regards, Mark Durenberger, CPBE -Original Message- From: Brian Rachford Sent: Monday, April 06, 2015 6:49 AM To: Mailing list for the International Radio Club of America Subject: [IRCA] New antenna report I had played around a bit with a corner-fed, corner-terminated "Superloop" ( http://www.bamlog.com/superloop.htm) last fall, but foolishly tried to make it too big and unwieldy to put up and take down every time, and was still lacking in knowledge about how to really do this stuff. Broadband was the key; my tuned loops have worked very well, and even more so when phased with a tuned vertical, but don't fully take advantage of an SDR. This time I was more practical and decided to limit the height of the antenna to 7 feet, so I can reach the top. Length-to-height ratios of about 3-to-1 or 4-to-1 give the best modeled front-to-back signal ratios for the cardioid pattern, so I've settled on a 24-foot length for now. That's about as long as I can go and still set it up in a wide range of orientations. I've always been more of a software person than a hardware person, but I'm using my renewed DXing interest to work on that. So, I put together a proper connection box for a potentiometer for the terminating resistance, and wired up a 16:1 impedance matching transformer on the recommended Fair-Rite 2873000202 binocular core for the feed line connection box. Due to the low dynamic range of my inexpensive SDR setup, I used a pair of Mini-Circuits filters to make a steep low-pass filter for my local 1450/1490 pair (and higher frequencies, of course) and thus can make use of higher amplification. For the latter, I hot-rodded a commercial upconverter with a semi-commercial low-noise amplifier on a bare PCB and my own ham-fisted soldering. The cheap RTL-SDR dongles have built-in amplifiers, but you get what you pay for. I still want to do some rigorous daytime testing to measure front-to-back ratios and such, but I had my first chance for some nighttime testing on the 25th. I decided that the most obvious test would be to point the cardioid pattern at 130 degrees into Mexico and do an SDR recording over the 10pm MST TOH (5UT). Indeed the dial was dominated by Mexican stations (including a new log of XEPRC), along with Texas and New Mexico, plus a few strong stations off the back end. Work and life (and work) got in the way. But, Saturday morning, I set up at about 280-290 degrees for the 2am TOH (9UT) and had pretty much the opposite with lots of California and Utah, a long-awaited confirmation of 920-KBAD out of Las Vegas, and several Canadians. After working through that SDR file, I swapped the antenna boxes to point to about 105 degrees, hoping to catch some stations to the east on day power at the 5am MST (12UT) TOH. That worked out insanely well with 7 new stations! Admittedly, if I'm DXing at that hour, it is almost always for trans-Pacific stations, one of the planned uses for this antenna. Thus, there's a lot of untapped potential in the eastern sunrise option. But, I was not expecting such a bounty. Using an SDR really seemed like cheating! Other pointings Sunday morning were not so fruitful, but I did pick up another new station and as often the case with TOH recordings, I added some new call recordings to my collection. So, the 10 new stations from these tests put me up to 486 stations since August 15th, 410 of which have been logged with their call letters (not always on the first log, though), and most of the rest on slogan/webcast combinations. I have recordings of about 90% of the call letters. About a dozen of the logged stations without call letters are Canadian or Cuban where it will be very difficult to ever get call letters, but the rest should eventually be amenable. Also, some of the unrecorded calls are common stations for which I'm only bothering if they are coming in particularly well. I hope to put together a blog post with pictures and other details eventually, and especially some daytime signal strength testing. May not be useful for all

Re: [IRCA] Station #500! (Big Loop antennas)

We're also comparing these to a SuperLoop about 150 x 30 and a full-wave MW horizontal loop. If it isn't too "QRN-ey" out there, we plan to log long-Wave results as well. It's nice to have almost unlimited space for all this...and using antennas that don't require good grounds (usually impossible out there). Results will be shared.

[IRCA] Belated unusual loggings
North American DX-ers enjoyed a few weird DX nights about a week ago, so we set out a 140-ft D-Kaz to see whassup. The brief loggings below reflect these notes from a 6 AM CDT SDR-catch on on 041615 : 1. NO Canadians! Normally about 50 percent of signals would have been Canadian stations. 2. Array pointed NNW from Central Minnesota but most signals were West and Southwest (High-latitude path skewing? Auroral?) 3. All signals had "fur" on the edges...a layer of sharp but minor impulse noise rode on each station. But interestingly, the noise floor on a vacant area (around 400 kHz) was below -110 dbm...quite normal. 4. There were a lot of mixes, where normally a lot of channels are monogamous. 5.

[IRCA] Sharing at the Convention
Good mornin' We're still on the hunt for folks who'd like to share their DX experiences at the July joint convention in Ft. Wayne. The line-up is starting to look pretty good, and there's always room for more. If you'd like to help us fill out the technical agenda for the convention, we could use your input...a chat of just about any length on an experience you want to share...or perhaps you'd like to ask us to cover certain topics of interest. Please let us know. If you do want to share, we can support you with audio-visual/handout copying etc to make your life easier, but we WOULD like to hear from you! Cheers!

Re: [IRCA] DKAZ Antenna
Okay guys help me out here. I always thought the sensitivity of a 'short' wire antenna was primarily from the sides, so that the wire would need to be orthogonal to the target signals. James' 150 feet would seem to be a 'short' antenna on the Medium-Wave band; I'm assuming his wire is elevated. So is it accurate to compare reception from the END of this long-wire with a directional antenna oriented ALONG the wire's azimuth? I know the answer is yes when the wire antenna approaches 1 wavelength...but I wonder about 150 feet. ...ready to be enlightened... Cheers!

I followed the design as Mark Durenberger's article http://www.durenberger.com/documents/DKAZREPORT051214.pdf I built the 140 foot long with 22 feet high supports. I am at present using a 900 ohm fixed 1 watt resistor and the direction is 120 degree. I have been comparing the DKAZ to my present 150 foot longwire running pretty much in the same direction, so far, the performance of the DKAZ has been very encouraging. Signals are appearing a lot stronger and earlier in the evening than the Longwire and I can tell signals from the north are reduced, while signals from the South are a lot stronger and louder. On a couple of frequencies I have checked, on the DKAZ there is a station with a decent signal while the Longwire has no station at all or a different station. I am still to hear a new station with this antenna but it will happen. Thanks for the fine article Mark and answering my questions.

Re: [IRCA] [NRC-AM] DKAZ Antenna
You CAN steer the D-Kaz by introducing a mechanical offset but you need two antennas; one in front of the other. I think you're right about what Nick meant. BTW: We're now playing with phasing, by adding a vertical at the "null" end of a single D-Kaz. Single frequencies can be knocked out of the ballpark (great Pest control) and adjacent channels do benefit from that additional nulling. Cheers!

I haven't had experience with two D-Kaz Mark, but do I gather then that you
haven't seen evidence of null steering with the DKaz alone? I HAVEN'T SEEN
EVIDENCE OF STEERING, JUST DEPTH ADJUSTMENT (PRESUMABLY INCLUDING
RE-SHAPING OF SIDE-LOBES).
FROM WHAT I'M LEARNING ABOUT THIS ANTENNA, SOME FORM OF DIFFERENTIAL DELAY
IS NEEDED BETWEEN MULTIPLE ELEMENTS TO ACTUALLY STEER THE NULL. KAZ HAS
STAGGERED THEM PHYSICALLY, BUT ONE ASSUMES YOU MIGHT ALSO BE ABLE TO DO THIS
BY PHASING TWO ANTENNAS. YES MORE VACATION TIME IS NEEDED!
I will need to look at the readings I recorded with a fresh eye. There
isn't much right off the back of an east- west DKaz at Grayland for
comparison, so it may be truer to say that nulls can be improved as Chuck
pointed out.But, it doesn't seem to be fine tuning about a fixed value
of 900 ohmsperhaps more frequency dependent, or ? I'M OF COURSE
CURIOUS ABOUT WHAT CHUCK HAS BEEN FINDING FOR NULL-IMPROVEMENT.
I had observed similar (and <900 ohms) termination values for Portland on
1190 and Seattle on 1000, one 50 degrees off the back of the antenna, one
30 degrees, but realize that although Portland on 620 and and Seattle on
710 also had similar values of termination, that value was higher.And
to throw it all out, Portland area on
1640 and Seattle on 1680 had different values of termination altogether.
THIS THOUGHT REMINDS ME THAT THERE'S NO SUBSTITUTE FOR ACTUAL
NULL-ADJUSTMENT. THE CURRENT CONVENTION SEEMS TO BE TO DERIVE F/B RATIOS BY
SWITCHING THE NULL-RESISTANCE IN AND OUT; I.E. MEASURING THE ANTENNA
PERFORMANCE WITH NO NULLING ("BI-DIRECTIONAL?) VS. THE PERFORMANCE WITH THE
NULL RESISTANCE IN AND ADJUSTED.
AND THIS IS A "YMMV" COMMENT. WHEN I USE A FIXED RESISTANCE FOR SDR
RECORDING ACROSS THE BAND, I DO A SIMPLE ARITHMETIC CALCULATION, AVERAGING
THE NULL VALUES FROM 15 TO 20 "BEST F/B" NULL-RESISTANCE MEASUREMENTS. IF
ONE WAS INTERESTED IN JUST A SEGMENT OF THE MW BAND, ONE COULD AVERAGE THE
NULL RESISTANCES ACROSS JUST THAT SPECTRUM...?
I'VE ALSO WONDERED WHY WE'RE NOT PAYING ATTENTION TO OTHER FACTORS WHEN
AUTOMATICALLY SPECIFYING "900 OHMS" (A SO-CALLED FLAG 'STANDARD.' ) WHEN I
SET MY D-KAZ TO WORK EARLY THIS SUMMER WITH #18 WIRE, I WAS FINDING NULLS AT
"SOMEWHERE ABOVE 800 OHMS" BUT RARELY NEAR 900 OR ABOVE.
WHEN I REBUILT THE ARRAY USING #16 WIRE, THE NULLS WERE FOUND BELOW 800
OHMS. I QUERIED KAZ, WHO SUGGESTED THE LOWER WIRE RESISTANCE COULD BE THE
REASON FOR THE CHANGE.
WHEN I RECENTLY MOVED THE ANTENNA TO A NEW ORIENTATION (MOVING FROM A
CLEARED SPACE TO A SPACE WITHIN A LOT OF TREES) I FOUND YET ANOTHER SET OF
NULL RESISTANCES.
SO I AGREE WITH YOU---A LOT MORE OPEN-MINDED OBSERVATION WILL BE OF BENEFIT.
THE TRUE HIGHLIGHT OF THIS EXCELLENT ANTENNA IS THAT KAZ IS UTTERLY
SUPPORTIVE OF OUR EFFORTS TO LEARN MORE!
CHEERS!

How would our readers feel about a "DX Telecast" or Live Stream DX session that you could log into and watch while it happens? Might only be 1/2 long or less - but it could be exciting... if you are into that kind of thing. I just suggested to Walt in Haida Gwaii that he video tape some of the stuff he sees and hears up there. Currently, a live streaming telecast from Masset would be technologically impossible because, for good or bad, the Haida Gwaii has not quite entered the new age of fibre optic technology and high speed internet.

[IRCA] CONVENTION UPDATE
We're less than a week away from the historic joint DX-Club Convention where
we'll welcome you to Minneapolis.
Some last-minute notes:
Eats:
The OPTIONAL Friday lunch ("IEEE Advanced Antennas") is a box lunch (Turkey
or Ham sandwich,cookie and pop). You previously indicated whether you'd be
attending and can pay us the $10 when you register. If you want to attend
this high-level working lunch, please advise NLT Monday.
Friday night we have scheduled a "pizza-fest" and if you can't tolerate the
stuff, you can make separate arrangements before the museum staff goes out
to pick up the food.
The Banquet Saturday night will be an 8 oz. Sirloin with fresh garden salad,
baked potato, green beans, fresh baked bread, chocolate cake, coffee or tea.
Don't forget about our DX-Pedition Thursday evening (details when you
check-in). "Formal" festivities begin Friday morning at 8:30 and conclude
late Sunday morning.
If you're flying, call the hotel upon arrival for the courtesy shuttle:
952-884-8211. Chances are you'll be sharing the shuttle with other DX-ers.
If you're driving, plug: "1201 West 94th Street, Bloomington, MN" into
your GPS. That's I-35 W and 94th Street. We'll appreciate it if you can be
a "car-pool" driver.
Any other questions? Please holler!
Regards,
Mark Durenberger

[IRCA] NEWS FROM THE CONVENTION-DAY ONE
Almost everyone has arrived; safely traveled and in good spirits. Perfect weather for the successful DX-Pedition last night; about 25 folks showed up to participate. Neil Kazaross set up a "Kaz" antenna and phased a pair of unequal BOGS. Richard Anderson brought out a 7-inch FSL antenna...a tad worse for gravity. Jim Dale and Mike Bates brought (or built on site) some nice loops and I put out a BOG and also a vertical. There were a couple of Perseus SDRs in attendance as well as some very nice radios including the new CR-1. This morning we dig into LEARNING AND SHARING. It was so great to meet so many nice people!!!

[IRCA] NEWS FROM THE CONVENTION UPDATE-DAY TWO
Bleary-eyed folks bravely made it to our early start yesterday, to take part in "formal" sessions on THE DX FISHBARREL, CHASING SUNSET SKIP, TAMING THE SHORT VERTICAL, DON MOMAN'S ANTENNA FARM, THE FSL ANTENNA, ADVANCEMENTS IN MW ANTENNAS AND A CR-1 RECEIVER REVIEW. Our presenters were awesome, well-prepared, energetic and eager to share. A number of us participated in the lunch session presented by the IEEE, on the use of meta-materials in advancing antenna performance. THANK YOU CHRIS FULLER!!! I'm not alone in declaring that I learned a LOT through the day. The afternoon highlight for most was the tour of the Pavek Museum of Broadcasting. We "clap" our electronic hands in appreciation of the hospitality and the tours of the Museum led by Steve Raymer, Danny Henry and Courtney Bakken. The evening sessions at the Broadcasting Museum followed business meetings of the clubs. As expected, each club has a somewhat different situation regarding membership size and activity level. Good, constructive input was provided. Ideas on improving Accessibility of club information were offered by several Blind members. Many favorable comments on the DX Audio Service and several suggestions on service will be transmitted to Fred Vobbe. The evening was highlighted by a spirited discussion on the future of the the DX Clubs led by Skip Dabelstein. Some clear thought was offered as to how we might reinforce the services our clubs provide their membership. The NRC members present at its business meeting unanimously approved a Resolution to be transmitted to the IRCA, expressing NRC's interest in joining IRCA for its Anniversary Convention in Billings 2014. IRCA presented its recognition awards to Lee Freshwater and Kraig Krist. Nick Hall-Patch is asked to provide further detail on these awards for the enlightenment of non-IRCA members. Genial warhorse John Callarman reflected on his years in the hobby and announced that he was donating to the NRC his new, unused Perseus SDR, to be sold in a club-wide auction. THANK YOU JOHN!!! Judos to all who attended...and our admiration for the energy (and stamina) of those who 'survived' a long and thoroughly enjoyable day. We also tip our hat in the direction of those fine folks who provided car-pooling to and from the Museum. If we haven't worn everyone out, we begin another day at 9 AM this morning. A report on "Saturday at the Convention" will follow.

[IRCA] NEWS FROM THE CONVENTION-DAY THREE
Even us 'old folks' seemed to have stood up well after another busy day. Saturday-morning sessions at the Museum addressed LOOP CONSTRUCTION, AN UPDATE ON SHORT-WAVE LISTENING, A REVIEW OF THE ULTRALIGHT SCENE, A LOOK AT HOW THE PAVEK MUSEUM CAME TO LIFE AND A REVIEW OF THE LONG-WAVE, ULTRA-LONG-WAVE AND "ALMOST-DC" BANDS. As usual, many of us learned something new. The afternoon was open, with a well-attended optional WCCO RADIO TRANSMITTER tour at the early-1930's plant that's complete with a boiler room, Civil Defense Fallout shelter and the ghosts of Arthur Godfrey and Edward R. Murrow lingering in the hallways. This station once boasted ratings of more than 50% of all radio listeners in the Upper Midwest. Our thanks to host WCCO CE Craig Walters. The Banquet at the hotel was rated 'excellent' by food critics (though a few of the steaks could have been slightly better-toasted). We enjoyed the stories of DX-er/Broadcaster Dean Sorenson, our Banquet Raconteur. The Great Big Auction moved more than 150 items, donated by members of all clubs. Phil Bytheway was priceless in his role as Grand Poobah, combing the best qualities of Milton Berle, Billy Graham, Colonel Sanders and John Commutta. Perhaps two-thirds of those present were bidding, spending an average of $20 each for some really good values. And we raised a bit over $100 for the Pavek Museum. This morning, as we say farewell to some of our long-distance travelers, those still standing or able to sit will be challenged by the DX Quiz and we'll view the latest installment of Scott Fybush's Tower Tour. Your friendly and weary correspondent will eventually deliver a convention wrap-up and some observations on what was clearly a successful event. Even our Minnesota weather was at its best!

[IRCA] NEWS FROM THE CONVENTION-THE LAST DAY
Sunday at 9 AM, about 30 of us were “left standing” while others executed travel connections. 29 of our 30 got very quiet after Scott Fybush passed out this year’s DX Quiz. Judging by the results, some very knowledgeable folks did their best to wrestle with the answers, but the final scores reflected the difficulty of the questions. In fact...it was a lot of fun. Scott nicely completed our presentations with the Fybush Tower Tour. That ‘photo paper’ as usual was so much more than a look at steel; Scott demonstrated his utterly complete knowledge of AM, FM and TV station assignments, changes and allocation activities. At 12 Noon Sunday we had a wrap. Goodbyes were made and hopes were raised that we could do all this again in 2014. A full convention report will follow with photos, statistics and comments.

A three-week trip to Europe that ended a few days prior to the convention blew my work schedule and travel budget, so a trip to MN in early August was a no-go for me this year. It's great the NRC and IRCA (and WTFDA) collaborated on a single event like this, and I hope it's the start of a new era. The hobby is fighting for its life in a world where radio as we've known it is changing dramatically and in some cases disappearing. DXing has a future if we can steer it along with some forethought. It can only help to cooperate and collaborate, and from all accounts this convention did a lot to get us headed that way. Nice! Thanks to you, and to all who made it happen!

The other half is still visible today to the west of I-75, just north of Cincinnati in the Camp Washington neighborhood. The old WLW studios and Crosley manufacturing facility rise high above the interstate and a real sense of history can be gleaned when exiting off Hopple Street. The WLW building is located near the intersection of Colerain Ave. and Sassafras St. One telltale sign that you have the right structure can be evidenced by the Morse code displayed on the art-deco fashioned building top. The building is in very poor condition today and hasn't been occupied with any business or storage activity for about ten years. On the southwest building floor is a large loading dock that faces a set of rail tracks that, at one time many decades ago, must have seen a very high volume of traffic as thousands of Crosley sets were shipped to dealers around the world. The building is not long for this world. If you have an interest in WLW and Crosley's history, I encourage you to take a short drive to the south of Mason and experience the building before it's gone. ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com

[IRCA] WESTERN DX-PEDITION
November 9-11, 2013 are set aside for the next Western Colorado/Utah DX-Pedition. In Mack Colorado, near the Utah/Colorado border, we're fortunate to have an almost-ideal site for some serious Beverage work. We have a field populated with 4-5 foot posts, in a grid that make it possible to extend about 1800 feet in almost any direction...and with good grounding. In addition we plan to deploy a "Double-Kaz" antenna and will do some comparison 'RF snapshots' in specific directions, to show the relative advantages of both antennas. The results will make it into a follow-up DX Audio Service column and the club newsletters. If you have some specific targets you'd like us to reach for, please let us know.

[IRCA] Double-Kaz antenna: Catches and comments
Neil Kazaross for explaining the Double-Kaz antenna at the recent joint convention. I became an instant convert when he displayed the EZNEC pattern for pickup capability. After nulling KOA, there were literally NO signals heard from the East...with the exception of WHO and WOAI wandering in and out occasionally. If there's one thing "wrong" with the antenna it's the ultra-wide acceptance angle. We plan to duplicate this DX-Pedition using D-Kaz antennas in BROADSIDE ARRAY, narrowing the beam-width. For this deployment, antenna dimensions were 120 feet end-to-end with a 20-foot height. A 10 db RF amplifier was used to overcome the inherently low-level output; most noticeable apparent on the low end due to the small size of the array. Further info available...

Re: [IRCA] Short antenna radials
To add to Dennis' info: The KSTP antenna was/is a 179.4/179.4 and appears to be considered a "Sectional" rather than a Franklin by the FCC. Nit-picking' I guess. Happy Holidays!

The new tower was built at the same place as the old and uses the same ground radials. KFBK and the KSTP day site both use Franklin antennas, the only two in the country. A Franklin antenna consists of two 180 degree electrical height (one half wavelength) antennas separated by an insulator, stacked vertically and fed at the center. The top half radiates and the bottom half is the ground. There are no ground radials.

One example I'm thinking of is such that the total length of the antenna AND all ground radials is 3 meters, and does it make much difference if you use a base-fed radiator with radials vs a center-fed segmented short dipole without radials. (The rule in 15.219 specifies the antenna, transmission line, and ground lead cannot exceed 3 meters.) There's other scenarios I'm wondering about, but I'll leave them off as I think it's beyond the scope of this list. As for KFI, I believe the original tower was there long before the industrial complex was built. So, I think there could be ground radials there already, and the new tower was hooked up to them? Or maybe they have another way of grounding it. KFI *is* a few dB weaker at my house than KNX, in spite of being 12 miles closer (99 vs 111). I think it's primarily the partial saltwater path for KNX in my case, though. At a friend's house in Moreno Valley, as well as at my grandma's house in San Gabriel, KFI is considerably stronger, like 10-15 dB. There is a very efficient station that I believe doesn't have ground radials - 1530 KFBK in Sacramento, CA. Also I suspect 1500 KSTP St Paul, MN's daytime site may also not have ground radials, but I'm not totally positive on that one. 73, Stephen Sent from my iPad ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com

You might find that your improved sensitivity actually has a bit of a peak at a certain range of frequencies, perhaps damped by your receiver's 50 ohm impedance. Maybe see how well some of the higher ratio matching transformers do at LW beacon frequencies in comparison?

Re: [IRCA] [NRC-AM] Grayland - Feb. 19-22, 2014
Bill: NICE work on your report! That's a lot of info; easy to understand. Interesting what you're finding with 'over-sized' D-Kaz antennas. I had settled on a 120 ft/20ft and found it suffered a bit on the low end of the MW band...but it turned out to be hot a long way up into SW. What height are you using with the 160-foot array? Here's a thought that may or may not make sense. I've often wondered if extending the null-pot to the shack might disrupt the linearity of the D-Kaz null. When the weather's nice, I work from the null-pot location, extending the receiver feed instead. 9:1 at the receive end is almost a perfect match to Cat5. I run the Cat5 around to the null-pot end (staying away from the antenna). The Cat5 feeds a 2:1 that perfectly matches the Perseus input. (Still found some RF amplification was a good idea for the MW low-end, but the stability was rock-solid and the null was fairly uniform across a couple of octaves.)

I'm still reviewing wav files but results thus far are here: <http://realmonitor.com/am_logs_grayland9.php> Nothing earth-shattering though hearing Indonesia [on 999kHz] at any time is welcome. A few observations: - 180' DKAZ is a GREAT low-band antenna. I've experimented with 88, 112, 128 and 140' versions before and this is by far the best for the low end. Unfortunately, high end nulls suffer as a result and it may be that 160' is a 'sweet spot' that covers nearly the WHOLE band. - Feb. 21 and 22 were like two different seasons as the 21st had nice sunrise enhancement to the Far East while the 22nd was more DU thanks to an A-index of over 40. - I used remote termination - 9:1 transformer at the null end of the antenna, ~600' of CAT5 to Room 15 at the Grayland Motel where a 100 Ohm pot 'controlled' the null. Worked very well and I was able to put a decent null on stations off-the-back as well as Portland area by virtue of being a little too close to the neighbors cyclone fence on the south side of the property which I believe skewed things a bit. - I also ran a ~800' BOG directly west from just outside Room 15. Not very impressive results on 'live' listening but I've yet to review Perseus wav files. Check out the 'Summary stats', 'Map' and 'AzBar' links on the grayland9 page as well.

[IRCA] The idea of merging NRC/IRCA
Karl, you smacked the nail straight on. Well-pounded! 1. ANY club has a certain percentage of members who want to see things 'made better.' Many decry the "aging" of clubs and dwindling membership. Good for them; clubs need energy. If that energy doesn't include the capabilities of fund-raising and new-membership promotion, so be it. It's a HOBBY club! 2. Though I was energized by Skip Dabelstein's session about this at last year's joint convention, I'm now realizing: "Clubs are getting smaller. So what?" (As you noted Karl, even if there were TWO members, we'd still be QSLing.) I'd add however that if a club is going to incur significant publishing costs it needs a large-enough membership base. "Aye, there's the rub." When a club can't justify significant expenditure, it cuts costs. Bully for IRCA going electronic! 3. Club "styles:" The French say: "Vive le Difference." IRCA and NRC ARE different; different leadership style, different community, different colloquy. I say it's nice to have these differences, and I draw from both, giving back as I can. We accept the differences and we Get Over It. 4. One issue that will always be a problem is soliciting direct support from a larger group of members. It's not fair to those few who do all the work. But it's a fact of life in ANY club. It is however, one area in which we could all actually make a difference. My friend Jim Wulliman of WTMJ/SBE says: "don't get mad; get involved." So...with all due respect to those who sustained this latest dialogue, let's turn our energies away from position e-mails on unsolvable issues and instead direct our focus on nagging our recalcitrant pals and pal-ettes into giving something back to the clubs. Last I heard, 'sharing' was no longer a dirty word. Cheers!

Both clubs are rolling right along. Both offer different things to different people. Your idea sounds like this to me: Cincinnati and Cleveland are both in Ohio - let's merge them. Huh? Second: Both clubs have very long standing and different communities of people. Yes, some people belong to both. There's nothing wrong with that. Some don't. Third: There's a distinct difference in philosophies that has always given each club its own personality. IRCA is west. NRC is east. Even more so, IRCA has a very large group of people who handle all the club tasks in a democratic way. It characterizes itself as being very fair and forthright. I really can't speak about the NRC since I have never been a member. When I think of the NRC, I see it as centralized and more formally structured. Nothing bad about it - simply a different approach. All well and fine. Cool beans. These thoughts from a former President and Board member of the IRCA (myself.) Fourth: The clubs have their differences, but they have always gotten along with civility. I joined the IRCA in 1981 and at that time joint reciprocation deals were being cut to share resources (like guide books) and to get along better. I honestly think that having two clubs has always been better than one. More is being done to support our hobby. More points of view have been shared. More has been developed. More has been published. Brilliant people have met more brilliant people. Accentuate the positive. We may be old and dying but we are all still fascinated with medium wave propagation and programming. I believe that if there are only two of us left in North America we will still trade notes. People have talked about CW this way for decades. More people use it than ever. I've saved the best for last. AM isn't going anywhere. The bandwidth is not really applicable to other technologies and is not sought for digital transmission. It will always remain as a very simple and effective way to send a wireless signal for a thousand miles or more. You need nearly nothing to pick it up - especially compared to Internet 'radio' - the most un-wireless method of transmission ever established! No other medium has this ability. Many small stations may fold, but the big boys will find a way to keep making money at it. AM is like baseball. It is simple and perfect. Les, we like being autonomous. We like being different. Is there anything wrong with that? Respectfully, Karl Zuk N2KZ ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.

Next Tuesday’s SBE Meeting veers away from mainstream broadcast engineering to look into a different world of ‘engineering’ endeavor: The interest, experiments, science and empirical observation gathered and displayed by a hardy band of amateurs called “DX-ers.” These folks take great pride in scanning the RF spectrum from ‘almost-DC’ to ‘almost-light,’ looking to copy and verify radio emissions from around and from off the planet. Mark Durenberger, renouncing his formative years as a child of FM, takes us into the world of AM DX-ing, to update you on a hobby that’s undergoing a renewal of interest. There are several reasons for this fresh attention; primary among them are the availability of new DSP tools and a better understanding of antenna theory (yes, even EZNEC)! What’s coming out of these activities are ways to better explain the fundamentals of radio reception, and a sharing of the methodology used to finesse what once was impossible...the capture of a 1-watt signal 1300 miles away...or the nulling of nearby 50-kilowatt pests to discover a distant station lurking under that modulation envelope. This fast-paced hour or so refreshes our understanding of some engineering principles related to AM reception...from Long-Wave through the Tropical Bands. We’ll keep you awake! ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
[IRCA] QSL COLLECTIONS
I'm a member of both radio clubs as well as a Museum Board member overseeing acquisitions for the Pavek Museum...a well-regarded home for Radio/TV history. www.pavekmuseum.org I/we have the utmost respect and admiration for the incredible patience, work and follow-up that goes into amassing any QSL collection. The problem that museums encounter with potential QSL-collections is what we learn from our research and acquisition-qualifications: 1. Sadly, logging a group of stations from a long distance is no longer considered unique enough to be of historical significance. At the Pavek we show what a QSL card is and what a "Verie" means to so many. But adding a large display of QSL cards really doesn't further the information we've presented, which is this: "there are folks out there doing this, and these two items are their instruments of record. Many have amassed thousands of these cards." That takes a minute or two...wyyy outside the attention-span of so many today 2. A QSL collection is really a PERSONAL accomplishment and stimulates happy memories when we review our cards. As such...unless the collector is himself a newsworthy person (say, a Walter Mondale)...a museum would have no historical context in which to display the collection. I think most other museums have found the same thing to be true. BUT: great QSL collections should not be lost! Hopefully we can bequeath them to someone a generation or so down the line, who might then be inspired to continue the hobby!

Really wacky conditions-- like something straight out of October. Along with the NHK big guns on 594, 693 and 774 (all at S9+ levels) 657-Pyongyang was at a similar blowtorch level, and 603-HLSA wasn't far behind Before a DU propagation swoon around 1130 the New Zealand Samoan language station 531-PI was also at an excellent level, but in general the Kiwis and Aussies were well below their summer strengths. Murphy's Law struck early in this DXpedition as the Edirol R09 MP3 recorder was accidentally left at home in Puyallup, making it impossible to post same-day MP3's (although the recordings are still being made). There was heavy rain here until around midnight, when it suddenly cleared up before the DXing session. The Rockwork 4 cliff was clear and cold around 1100 (0400 local time), when the session started with both the Asians and Kiwis at potent levels. Unfortunately Kiwi propagation hit the skids around 1130, so 531-PI was the only vibrant Kiwi recorded. The Japanese big guns went on a phenomenal run from 1145-1330, hitting almost science fiction levels on 594, 693 and 774 while the Kiwis and Aussies played hard to get. The raspy North Korean carrier on 702 produced some fair audio around 1215 (fair level that is, but equally boring), while 603-HLSA went on an excellent run around 1316 (over two co-channels, one of them apparently a weak 603-Waatea). The Japanese big guns ! ruled right up until the band folded around 1400, although 972-HLCA had a late revival around 1355 to reach an excellent level. I was looking for some DU propagation after these Asians bailed, but only wispy signals from the Aussie big guns on 702, 792 and 891 were to be found. Knowing very well that chasing these ghostly Aussies was running up against the propagation grain I decided to get off the frigid cliff around 1410, and take my chances on better DU propagation sometime during the next two days. Overall it was a thrilling session, and hopefully the first of three such wild rides. 73 and Good DX, Gary DeBock (in Cannon Beach, OR) DXing at the "Rockwork 4" ocean cliff site (2013 DXpedition video at http://www.youtube.com/watch?v=qWSqvb9NdLo ) C.Crane SWP 7.5" Slider loopstick Ultralight + New 12" DXpedition antenna (design photo posted at http://www.mediafire.com/view/m4vpd78b91nowxb/12-inchDXFSL-004.jpg ) ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com

[IRCA] Reversible Double-Delta
This evening, 3 Phools in the Phield set up a reversible 140-ft. Double-Delta antenna at a quiet place in Burnsville MN. The goal was to see what sort of nulling we could do off the "backside" of the antenna (whether the "backside" was the North end or the South end). Think of it as a super-hot loop antenna, but unidirectional in pickup rather than bi-directional. It works. On a number of frequencies we were doing armchair copy of one station; flip the antenna and the first disappeared while another came up just as well...from the opposite direction. We were oriented North-South since most of our local pests were North of us. Antenna reversal is as simple as flipping a switch. Interestingly...the null held up across the band; little or no re-nulling was needed. Surprisingly, we could do no better than about 27 db nulls of local stations. Our conclusion was that the Double-Delta seems to like low- and medium-angle skywave and doesn't discriminate as well with strong ground-wave signals. We will also investigate whether the extension of the null pot and RF takeoff VIA UNEQUAL LENGTHS OF CAT-5 degrades the null. (I've seen better than 40 db null on these guys when the null pot is right at the leg of the antenna; in this case we had run 150 ft. of Cat-5 to get to the receiver.) Mike Bates and Jim Dale may chime in with their own observations. It was an evening well-spent.

[IRCA] Reversible Double-Delta
So perhaps it's the 140-foot size, rather than the use of Cat-5 extenders, that created the 15 db difference in F/B nulling. Previously, I was doing better than 40 db at times with the 120-footer (though that WAS with the null-pot right at the antenna). Earl Higgins asked for some loggings; they're on the way.

This is a very important aspect of this design since SDR users want to record the entire band. On mine at home using fixed resistors I can get 30+ to 40 dB nulls on locals. This means most back nulled regionals go away at night as they are overwhelmed by DX from the desired direction. You can always phase it vs something else if a single freq very deep nulls is needed. When I got KCEG on 780 14 miles NNW of WBBM, I phased one of these vs a random piece of wire about 30 ft long on the ground. Non SDR users would do very well phasing one end of a Double Delta (Double KAZ or whatever you want to call it) vs the other. Nulls clearly exceed 40 dB, but are very narrow banded..ie basically just the frequency nulled +/- not much more than 10 KHz. The phased configuration is also bi-directional since you switch the phasing to null the opposite direction. 140 ft length is likely the max for good high band F/B as it seems to worsen if you make the antenna much larger. 73 KAZ -Original Message----- From: Mark Durenberger Sent: May 18, 2014 10:13 PM To: MNDXC , "DX @NRC" , DX-IRCA , Shafer Mike , Baumgartner Fred-ARRL Subject: [NRC-AM] Reversible Double-Delta This evening, 3 Phools in the Phield set up a reversible 140-ft.

Fourth visit this year, but the first that I was able to devote a lot of time to DX. I had fun erecting various antennas and testing them, and in some cases, taking back down. Conditions were OK for SW generally, and at times, very interesting for MW DX. I'll have a separate email for SW DX. Receivers used were 2 Perseus SDRs (one live, and the other using Mestor for timed recordings), and an AOR 7030+ receiver. Antennas used with most important first, as follows, along with comments: 1. NW BOG (Beverage on ground). 700' or so in length. Unterminated. This is always my go-to antenna with excellent results. It's the first antenna up, and the last to be removed. DX RPA1 amp added at the antenna lead in, as well as chokes on both ends of the coax. 2. DKAZ aimed 220 deg. This was an impressive antenna after a few hiccups. Before local dawn, it was often as effective as the BOG. And only requiring 140' of real estate. Fed to a FLG 100 LN head, and via coax to the Wellbrook interface. Often the only antenna that would hear Hawaii well. This one's a keeper from now on. Not good for LW, however. The DKAZ performed very nicely on SW, in addition to MW. 3. ALA 100 LN antenna: double loop, separated by about 30 cm, as suggested by Andy Ilkin (Mr. Wellbrook). Aimed NE/SW. Normally an excellent all band antenna. This time around, it somehow did not perform as well as in previous DXpeditions. The only change was that I purposely separated the 2 loops to 30 cm, from around 10 cm (as recommended by Andy). The other possibility was of a coax fault, although the lead in is milspec RG 58 cable. Almost in no case, this time, was the ALA better than the others, even on SW. More investigation needs to be done as it's a very quick antenna to get up and running. 4. Mini Beverage aimed due north, terminated into the sand on the beach, and under water at high tide. About 500' long, so I call it a mini-Beverage. It is elevated about 12' or so. At times a great antenna. I was hoping for some European MW DX, but nothing ever came about. Often picked up Alaskans very well, and at times equal to the NW BOG for TP DX (like this morning). This is a permanent antenna, except for the beach portion. 4. Parallel BOG to the NW BOG. Fiddling with it, and feeding it into a Misek Phaser, for instance, did nothing at all. Didn't seem to enhance anything, so I moved it towards the SW. 5. SW BOG: about 600' and aimed about 230 deg. This path takes it directly across the land mass of Haida Gwaii (whereas the NW BOG aims to the direct open ocean). Overall, not a great performer, even with a DX-RPA1 amp. Once again, it could be due to a lossy coax, as it was quite a way to the shack, or the direction. I do recall in the past erected a similar BOG with much effort (with Bruce Portzer) and also being disappointed. Makes me attribute this to the land mass phenomenon. Not ideal for BOGs. Here's the report for MW. As always, excuse the typos, or mistakes. Please let me know, and I'll correct them. Part 1 (in order to get under the limit for IRCA): 531 AUSTRALIA unid, Oct 23 1429 - For the first time this week, English is dominating this channel. Before 14:00, I was hearing a lot of American music. An extended newscast at 14:00, including weather and marine forecast. Little sign of any NHK1 stations which dominate, and only a hint of Avtoradio. Unfortunately, this is the noisiest morning with lots of static crashes. Mentioned a phone number ending in '4139'. I know it's very difficult to ID stations on this frequency. Funny that the usual DU frequencies are absent when checked earlier. At 14:35, there seems to be 2 English speakers. One I suspect may be DYDW as it sounds like a sermon. Didn't last long, as the dominant Australian came back. (Salmaniw, Masset, BC) 531 JAPAN Morioka 10 kW NHK1 JOQG, Oct 20 1510 - Very strong Japanese opening this morning with many 1st, 2nd, and 3rd tier stations heard. What's more interesting to me is the co-channel with pop music, which I'm quite certain is Avtoradio Sakhalin. One of the few MW channels still on the air in Russia. Reception of the latter would be pretty decent, if not for the powerful JJ station!. (Salmaniw, Masset, BC) 531 JAPAN NHK 1 Morioka 10 kW JOQG, Oct 16 1513 - The lower half of the band is interesting at this time, as it's solid NHK 1 on each frequency. Good signal on 531 (with a weak cochannel), 540 at good/very good lev
Re: [IRCA] DXpedition capture files?
I think a lot of us would contribute Perseus snips if they didn't have to always be current. Some form of pre-upload "vetting" might be a good thing, to minimize congestion. It could take the following general form: "I have TOH snips of MW taken at PM (AM) on a 140-ft Broadside D-Kaz oriented 325 degrees from (QTH). Payload size___. Holler if you want them" The offered snips are uploaded only if someone asked for them. 'Admin' keeps the list of offers and from time to time posts a reminder here that such snips are available by request. I'd be more than happy to be that 'Admin'...but first we need a storage site.

I haven't seen any comments about this yet. Recent DXpeditions would include Masset, Rockworks, and Grayland on the West Coast as well as any East Coast activity such as the Miscou Island, NB outing (about which I have read remarkably little so far).

This is great info; thanks Guy! Regards, Mark Durenberger -Original Message- From: Guy Atkins Sent: Saturday, October 31, 2015 3:31 PM To: Mailing list for the International Radio Club of America Subject: Re: [IRCA] DXpedition capture files? Hi Mark, As some folks on this list know, I used to run a Perseus SDR blog for a few years, and a Flexradio SDR-1000 for a few years before that. When I had the "Five Below" Perseus blog, I included a "Perseus WAV Files Directory" section that over time became quite popular. At the time, the hosting service MediaFire appeared the best choice for me (their reasonably priced "Pro" plan) so that's what I used as the Perseus WAV file storage. If I was beginning to share SDR recordings today, I would investigate Microsoft's OneDrive and Google Drive. Last year OneDrive upped their file size limit to 10 GB, and Google Drive offers a maxium of 5 TB (yes, that's TB as in Terrabytes!). Both services allow easy sharing of files and folders. Chuck Hutton's "Perseus WAV Chopper" is an excellent utility for trimming WAVs to just the pertinent time range of interest (60 seconds centered on top-of-the-hour for instance). I wish something like Perseus WAV Chopper was available for Elad-generated files! Then it wouldn't matter if a DXer like myself was using 4096 MB as their file size for recording; the WAV could still be trimmed down to something reasonable in size. However, at least the current size limits of OneDrive and Google Drive allow these more massive WAVs, but of course there's still the long, l-o-n-g wait time for downloading the files that most DXers will encounter. 73, Guy Atkins Puyallup, WA -- Forwarded message -- From: Mark Durenberger To: "'Mailing list for the International Radio Club of America'" < irca@hard-core-dx.com> Cc: Date: Fri, 30 Oct 2015 19:02:27 -0500 Subject: Re: [IRCA] DXpedition capture files? ...I' hoping Guy will weigh in regarding his experiences in hosting SDR recordings.

[IRCA] NOISE-BEATING
I've been involved in recent threads with some of you, regarding common-mode noise suppression. I went to Fair-Rite with a question about suppression on USB cables and wanted to share the response: Hi Mark, Thank you for your Ask the Adviser question! While I am unsure as to what is the source or frequency of your common-mode noise, given that USB clock frequency is 24 MHz I would say that 61-material would be suppressing at too high a frequency (> 200 MHz) to have an major impact. Instead, may I suggest trying a broad-band material such as 31 (operating between 1 MHz and 300 MHz) or 43/44 (operating between 25MHz and 300 MHz). As for the number of turns, this is proportional to the impedance you require (Z ~ N^2) and again depends on the amount of noise suppression your system requires - typically one turn (or one pass through the aperture of the core) should be sufficient. Hope this helps! Sincerely, Rachael Parker Cheers!

Re: [IRCA] Alliance Urges FCC to Reconsider Protection Proposals
WHAT A HOOT! "Fix AM...OH...but don't go QUITE that far in fixing it" Now that the FCC is considering "revitalizing AM" by adding the sacred cows to the mix (the 1-As), the entrenched interests are up in arms. "Fix things...but Not In My Back Yard." Old-timers are reminded of the fierce lobbying of the "Clear-Channel Broadcasting Service" in the 60's; even the arguments are the same: "Don't kill Clear-Channel Broadcasting; we need it for National Defense, weather alerts" etc. etc. I doubt there are more than a half-dozen 50-kilowatt 1-As who try to service their entire protected-coverage areas.

Re: [IRCA] Single-turn tuned loop article
Great piece! It's interesting to note Andy Ikin at Wellbrook DOES specify a maximum size (21m for a triangle, for example) but I always assumed that had to do with the configuration of his ALA 100 amplifier input.
