Still have not had a chance to install permanent antennas, so I am using my portable Inverted Wye with 2 above-ground radials. Seems to work pretty well from here. I have even been able to bag some DX and Hawaii on 40 with it. One of the real plusses of this QTH is the extremely low noise, even quieter than it was in North Dakota. Last evening I heard both FOXes pretty loud at the start, but by about 25 minutes into the hunt they were essentially ESP = gone for the night. Hopefully conditions will improve as the winter proceeds. 73, --Doc/K0EVZ > [Original Message] > From: Jay Henson > To: Low Power Amateur Radio Discussion > Date: 11/19/2003 8:13:05 AM > Subject: Re: W0IS preliminary log > > Rick > > My 579 report on your signal was an honest report.

All hams are welcome. Net control operator will be Chuck, K1CL, operating from Chelmsford, MA. Very unusual conditions last week, despite relatively low noise. John, K1RC, who lives only five or six miles from me and usually comes in with an S9+20dB signal, was barely making S7. Charles, W2SH, who is usually a solid 599, was essentially not copiable at 229 or less. One or two other stations could be vaguely heard, with no copy possible. With all the wind that night, I went out to check my antenna to be sure it was still up.... It was. Thanks to John and Charles for checking in, and to those who tried unsuccessfully. Hope to hear everyone this week. 72 DE K1CL, Chuck ------------------------------ Date: Wed, 19 Nov 2003 18:39:11 -0700 From: "James R.

Forgive the cynicism, but I grew up, at least hamwise, in an era where receivers drifted Kilocycles (thats Khz since 1967) in a half hour or more befoer settling down. IN 1965 we would hgave laughed at anybody complaining about 100 Hz drift in a few minutes before settling down. Nobody would have believed it. I have an old Hammarlund HQ-170 that drifts about 3 Kcps (oops KHz) in about 30 minutes then settles down. This was typical of the era. Th= e HQ-170A ran the oscillator tube (valve) filament all the time to reduce the drift. But, that aside, I think that a simple syntehsized BFO would be a good project. Being able to program it for the mode would be very useful. It would probably have to be simpler than the 9850 projects. You probably knew this, but you don't a BFO for AM. :^)=3D. - Dr. Megacycle KK6MC/5 ______________________ James R.

I see a small difference in the BFO circuits: The KX1 has an inductor and no variable capacitor, and the DSW-II has a variable capacitor and no inductor.

Paul is right -- they do use a photolithographic process to etch the boards, but they use Gerber files to produce properly-sized images. if you're looking for free PCB software that will generate Gerber files, try Eagle -- i believe its freeware edition (for nonprofit use) speaks Gerber. and if you're looking for a manufacturer, i suggest Advanced Circuits (www.4pcb.com). I have used them extensively in the past, and they do reasonably good work at low prices. In fact, if you happen to be affiliated with a university, you can get a "33 each" special made, where they send you three 2-layer boards for $100. They specialize in prototype and short-order work, and are willing to work with you to get problems manufacturing your board solved.

I started by finding W0IS barely above the noise and then worked him about 02:20. After that, it was off to find you right in the noise on 7.0416. Shortly thereafter, you completely faded out and all I could copy was a loud, noisy buzz and some stations who were not in the hunt. Determined to stick it out, I thought I might end up listening to that noise until 04:00. Then, about 03:40, I heard one of the most amazing band transformations I've ever heard. K3ESE reappeared just above the noise and that was the first time I heard you in over an hour. That is when we QSO'ed. Across the next 5 minutes the noisy buzz dropped way off, and your signal came up Q5! You held that until the end. These have been some tough hunts! Hats off to the FOXes.

Got the shack in the basement in pretty nice shape and using the MFJ 901B tuner achieved excellent max pwr out with low swr for both the 20m and 40m dipoles up in the attic. But the last two times I've fired up the 180S the usual settings were no where near correct, and I've had a terrible time getting even an approximate match for the 20m dipole: 40m so far has been impossible. Double checking the usual settings with other qrp-scale gear confirms they're right on--just the 180S has gone "flakey" (highly technical talk). So can a transceiver change in terms of the impedence it seeks in an antenna system? And if so, can it be corrected, or rather, where would I begin to figure out what is happening?

Now, since things were a bit hectic, I only decided to take part 5 minutes before the test started, I could have done things better. No detailed test plans here. Note that for next time. I used my TS-850SAT (10 Hz dial resolution) and a spectrum analyzer program. I tuned to the low side of zero beat and measured the frequency from the spectrum analyzer. Recorded the dial frequency. I tuned to the high side of zero beat, using the same frequency on the spectrum analyzer. recorded that dial frequency. So the measured frequency should be the low dial frequency plus half the difference between the high and low dial frequency. Afterward I regreted not calibrating my method against a station on a known frequency like WWV. Then I realized that I could do that after the test. So I did. My measurements of WWV's frequency on 2.5, 5, and 10 MHz are a bit high on all frequencies, so I will take that into account when reporting my measured W1AW frequency to the ARRL. I suspect that WWV is on their advertised frequency, or at least that they have better frequency mesuring capabilities than I do. :^)= At first blush, I figure that my method is accurate to about 5 Hz and precise to about 5 Hz. We will see when they post the results. I could hear W1AW on their 40 M and 80 M frequencies. I made several measurments and will take the differing measurements into account when reporting my measured freqwuency to the ARRL. There are a lot of refinements that my method needs, primarily in the measurement of the zero beat frequency. I will be better prepared next time. I suspect that with the same setup I could get accuracies to a Hz or two, with similar precision. Did anyone else play in this fun???? - Dr. Megacycle Kk6MC/5 ______________________ James R.

I agree with the speed business except for guys like me "out in the country" where even DSL is unavailable. Options are satellite or wireless link which I have to a local system. Works up to 1 Mbps sometimes but usually 400-700 kbps. But I can't see that there are enough folks in that group to sustain the huge capital investment and then the upkeep of the power line equipment. Most power companies cannot even keep wire joints, insulators, and lightning arrestors, etc. in condition much less a lot of r-f gear on every transformer, etc. Nope, You're right: the future is in megabit and up speeds.

It seems that the classic transceiver problem of achieving true zerobeat is with us tonight. At least for those of us who don't have rigs with "tune" buttons. I am returning to the hobby after a 40 year hiatus and didn't have any experience with transceivers until I bought this IC706. I have only recently come to see that the BFO offset frequency (600 Hz Default) is what I have to tune for, by ear, to achieve zerobeat. My ears aren't that good for average hearing these days, let alone detecting 600Hz. So, I am collecting the parts to build a tuning guide based on the LM567. Hopefully, this will enable me to perform an accurate zerobeat.

For an audio frequency analyzer, I use DigiPan which will place a 31.25 Hz DSP filter around an incoming signal and read the frequency to the nearest 0.1 Hz. It will also track small changes in that frequency and update the display in real time. Prior to the test and after an hour or so of warmup, I calibrated the PRO2 dial against WWV on 5 MHz such that when I set my dial to 4999.000 USB, I got a tone of 1000 Hz (if the dial was exactly right and if there wasn't a fractional part of a Hz out there). Turns out the PRO2 dial was reading 0.2 Hz too low, per DigiPan, so that gave me the dial calibration correction I needed. Then I tuned in W1AW at 7049 and when I found them, I tuned for a 1000 Hz beatnote in USB. My dial setting was 7049.410 to give a 1000 Hz nominal offset. So, I knew that the frequency was roughly 7050.410. Using DigiPan I measured the actual offset audio frequencies to the nearest 0.1 Hz. So, during the test I would observe the DigiPan delta frequency on W1AW and frequently switch back to WWV to see where the dial calibration was sitting. After several such switches I had several dial calibration deltas and several measured signal deltas. Finally, I corrected the average dial readings by applying the average dial corrections from WWV. Then by adding the observed average delta between my corrected dial setting and the W1AW signal from DigiPan, I was able to convert the dial reading to the W1AW frequency to the nearest 0.1 Hz. A quick tune to that frequency obtained zero beat to the nearest Hz so I confirmed that I was applying the corrections in the proper direction. Sounds complicated but actually very simple to do. This is the Famous W5YR Method for calibrating just about anything having to do with frequency and dials! <:} I use it to keep the PRO2 and the 746PRO dials to within couple of tenths of a Hz with WWV. Just tune in WWV, say at 10 MHz, only set the dial at 9999.000 USB. If your dial is "on" the DigiPan track will be on 1000.0 exactly. Any difference is the error in dial reading. Same thing works for 10,001.000 LSB. By tuning for an offset, you get a signal that you can work with instead of trying to deal with frequencies near zero. I have cross-checked this method against true zero-beating of WWV's carrier and it is spot on. So, Jim, to answer your question, the PROs are usually no more than 0.3 Hz at most off WWV at 10 MHz. If I am patient enough I can adjust the trimmer on either PRO and put it spot on, but it is a very tricky adjustment. Oh, yes, one other error source is the sample rate of your sound card. Verify this by tuning in WWV in AM (to take dial calibration out of the picture) and seeing what either of the tones reads on DigiPan. On mine, for example, a 600 Hz tone will read exactly 600.0. If it did not, I would observe that error and apply it later. Most soundcards have provision for minor frequency adjustments. Thanks for your interest and for asking!

WE no longer adjust for actual zero frequency but rather for a zero *difference* frequency. Your device will help a lot to do that. As a practical matter, though, I have found very little need to be concerned about "exact" zero beat in making a contact. With a little practice, you can get to where you can get "close enough" to be heard. A frequency-measuring test like tonight is something else, of course. The easiest way to tune a signal is to just tune first in normal CW mode and then switch to CW-Reverse mode. If you are properly tuned the pitch will not change. If it does change your tuning until switching from CW to CW-R and back again does not change the beatnote. Have fun with the new rig!

These are also generated by the PCB package. 73, Leon -- Leon Heller, G1HSM Email: aqzf13@dsl.pipex.com http://www.geocities.com/leon_heller ------------------------------ Date: Thu, 20 Nov 2003 00:49:33 -0600 From: "pschweit" To: "Low Power Amateur Radio Discussion" Subject: [161576] Optimal takeoff angles Message-ID: <002c01c3af32$763de7e0$1ee6add1@oemcomputer> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Question what would (in reality) be an excellent takeoff angle for good propigation? de K0CD rob ------------------------------ Date: Thu, 20 Nov 2003 18:01:18 +0900 (JST) From: =?euc-kr?q?=B9=DA=20=B1=D4=C8=A3?= To: qrp-l Cc: peyukr@yahoo.co.kr Subject: [161577] MV2107,2109 datasheet Message-ID: <20031120090118.8938.qmail@span.corp.yahoo.com> MIME-Version: 1.0 Content-Type: text/plain; charset=euc-kr Content-Transfer-Encoding: 8bit Hello?

Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Hi gang, After seeing the start of this thread, I decided to check my DSW-II-20 and see if there was any noticeable drift from turn on. The first test was with the rig in my shack which is a fairly temeperature stable environment. I keep it around 70 degrees in the winter and 78 degrees in the summer. I warmed up my DDS signal generator for an hour to insure that it was very stable (it doesn't drift more than 1 hz from a cold start @ 70 degrees F.) I then set it to 14.035 (the DSW's last used frequency - I use a DSWK chip from Jackson Harbor Press with frequency memories in it instead of the DSW's original PIC). I turned on the DSW-II using the same battery supply (12V 12AH gel cell) and by ear, the tone did not change from turn-on till I got tired of listening to it about 5 minutes later. Next, I put the rig in the refrigerator and cooled it down for approximately 5 minutes. I took it outside (50 degrees F) and performed the same test. I didn't notice enough change in the tone to believe there was any sort of problem. It was completely stable inside of 1 minute and remained so throughout the remaining 5 minutes. I don't see where a DDS BFO is even necessary on the II, other than possibly selecting sidebands. This would be about the only reason I could think of to do such a thing. I can't speak for the earlier DSW series as I've only seen one, not operated it. I'm currently experimenting with the DDS daughter card put out by the AMQRP club a while back, with the idea of eventually building a 75 meter DDS controlled SSB transceiver from KD1JV's plans on his website. This is a very long term project, as I don't have a lot of money to spend on it right now, and it has had to take a back seat to more important things like keeping food on the table - :-) Jim - W0EB Wichita, KS -----Original Message----- From: owner-qrp-l@Lehigh.EDU [mailto:owner-qrp-l@Lehigh.EDU]On Behalf Of John Meade Sent: Wednesday, November 19, 2003 7:37 PM To: Low Power Amateur Radio Discussion Subject: Re: More thoughts on the DDS BFO...and...how 'bout that Elecraft KX1 ? I just turned on the KX1 and the pitch of the station that happened to be on that frequency has not changed in the past 30 mins. I see a small difference in the BFO circuits: The KX1 has an inductor and no variable capacitor, and the DSW-II has a variable capacitor and no inductor.

Investing is trying to predict the future with the knowledge you have today. This knowledge is more often than not, not based on credible evidence, but mostly on expectations. (If there would be credible evidence of a particular stock increasing or decreasing in value some time in the future, you may have an insider trading case on your hands. But that would lead to a discussion on what we consider "credible evidence" and if the evidence (knowledge) was public or not.) The BPL industry will be doing their best to make (potential) investors think that their companies will become high yield investments, again, without credible evidence, just expectations. They will (and probably have, I think I saw one BP proposal) hire companies with very recognizable names to help them with their business plan, how to present where they will be positioning in the broadband market etc., so they can use these names. You could supplement the knowledge a (potential) investor has by sharing your knowledge, your opinion, even your gut feeling. Whatever you have to say on the subject in that discussion may be a contributing factor in the decision of whether or not to invest in a particular stock. Having the word "controversy" being associated to BPL could be beneficial. BPL technology is controversial. We know it, now investors need to know it so they can make an informed decision. I don't know why anyone would listen to what I have to say, but I do know that they will certainly not listen if I don't speak. I leave the decision to listen or to act to the person I speak to, without pondering why (which I probably should). Of course, all of the above is just my opinion on how I think this world works. I have no credentials whatsoever, so I probably shouldn't even have entered the discussion on this list. I'm merely an observer and student. 73, --Alex KR1ST ------------------------------ Date: Thu, 20 Nov 2003 07:47:32 -0600 From: "Dave Redfearn" To: "Low Power Amateur Radio Discussion \(E-mail\)" Subject: [161586] SOLD - CW keyboard kit board.

You want to report the transmitted signal frequency, not your rigs displayed receive frequency, which can easily be off. (For instance, my Ten Tec Scout actually transmits CW 600 hz or so off from what is displayed when I'm receiving. This display flickers as I key the rig and the offset is removed for transmitting.) George's process for seeking out a 1000 Hz tone is definitely the better way to make sure you know what is up. Besure to check CW-reverse if you have it.

How do you do it? - Dr. Megacycle KK6MC/5 ---------------snip--------------- W1AW was at 7050.4112 KHz and 3585.3846 kHz By definition, I got 10.000000 MHz for WWV there, since I zero beat WWV and forced my DDS signal generator (Trevor's, KG6CYN, design) to read 10.000000 right there. Then I tuned as close to zero beat with W1AW as possible in the 1 Hz steps the generator can provide. I turned off the AGC on the K2 and used a 600 Hz filter setting in CW mode. W1AW was tuned to produce the nominal 700 Hz CW pitch. Using a universal solvent flooded bilateral carbon-based omnidirectional pressure-to-emf transducer (pair of ears - dewaxed - hi) I closed in on W1AW as close as the 1 Hz increment allowed, then timed the number of audible beats in a ten second interval to estimate the fractional Hz. But, Jim's question prompted me to realize that I didn't think to "measure" WWV at 5 MHz and perhaps 15 MHZ to possibly interpolate a correction factor for the DDS tracking. We'll see how close I got when they post the results after 19 December. I suspect that while I'm publishing 0.1 Hz precision, that's no doubt false precision, and my real accuracy is more like +/- 2 Hz. Still, if it turns out to be even as good as +/- 2 Hz that would be ~0.3 parts-per-million, and that's not too shabby for less than one hectobuck worth of equipment (ten sawbucks for the metrically challenged - hi). Given that I spend a fair amount of time in class trying to get physics students to understand precision, accuracy, and uncertainty, this was a fun exercise. Hmmm, maybe the next FMT could be assigned as homework....... can students still find tar and feathers? :^)) 72 Jim, N5IB who still won't venture very close to the band edges :^)) ------------------------------ Date: Thu, 20 Nov 2003 08:54:55 -0600 From: KD5NWA To: hoglund@wfu.edu Cc: "Low Power Amateur Radio Discussion" Subject: [161598] Re: Changing Impedence?

Propogation as a 'science' seems to be more metaphysics than physics. Anyway, takeoff angles from 0-20 degrees will give you the best chances. There are tables in the antennas section of the ARRL Handbook that list angles for DX work, listed by origin, destination and band. I'm pretty sure that anybody with a sliderule and high school math could figure these tables, but major lobe angles like these in the real world may take more antenna mojo than many of us can achieve. Low wire antennas and unknown ground parameters have me in the dark as to what TO angles I have from here. The tables list an optimum angle from here (northeast) to Europe as 5deg on 10 meters, yet when 10 is open I get consistent s10+ reports from eastern Europe, Italy, Israel, etc., with <100 watts from 30 year old 6146's to a wire dipole at 35'. Experiment!!! Antennas are fun to mess around with, and in fact are the one part of a ham radio system that the user can easily home-brew and modify. I get 500' rolls of #18 stranded copper from Home Depot to experiment with. There are dipoles and horizontal loops and inverted L and G5RV and vertical wires.... Have fun.

I apologize for any personal implications to the posting. My younger son is a professional portfolio manager and he both operates and is active on several investor chat boards. I was basing my opinions on his comments about all the "noise" that appears on the boards; i.e., "facts" about companies and situations from individuals without any credentials or background to make their comments of interest or have any meaning. Everyone has an opinion and most savvy investors learn early on to separate the wheat from the chaff. I personally think that the worst thing that could happen is for a bunch of hams to hit these boards, for example, with a lot of factual but still apparently whining sob stories about how BPL is going to ruin their hobby, as well as crush the entire community of HF spectrum users. The instant the word "amateur" or "ham" is used, the typical investor will, in my view, discount anything further as unprofessional and of little merit. The general public, in fact, probably would in the ratio of 9/10 associate ham radio with CB. Thus, I heartily agree with Ed Hare. Let the credentialed sources carry the ball - ARRL and Ed with his factual measurements - and let us Joe Hams cross our fingers and trust our representatives - the ARRL - to do their job and work closely with NTIA and others to bring a quiet, acceptable halt to this nonsense. Again, I intended no reflection upon you personally, Alex. I am no more qualified that the next guy to be giving advice, but it occurred to me upon reading your posting that, as Ed implies, we run the risk of undoing as much as doing. 73/72, George Amateur Radio W5YR - the Yellow Rose of Texas Fairview, TX 30 mi NE of Dallas in Collin county EM13QE "Starting the 58th year and it just keeps getting better!" w5yr@att.net ----- Original Message ----- From: "Alex" To: "Low Power Amateur Radio Discussion" Sent: Thursday, November 20, 2003 7:42 AM Subject: Re: a positive sign for BPL > Hi George, > > George, W5YR wrote: > > > Alex, what is your or my credibility in discussing ("informing") the > > "financial community" about the ills of BPL? > > > > Why should any investor listen to either of us?

I used SSB to remove any aspect of the receiver offsetting the receive frequency that I could not measure and confirm. By receiving WWV with the dial set 1000 Hz high (LSB) or low (USB), one obtains an audio signal that can be measured to the nearest 0.1 Hz with DigiPan. Thus only the master oscillator within the receiver is involved in determining the dial calibration.

Kinda like the old "Trust me, I'm from the government and I'm here to help you." I think sitting back, crossing our fingers and hoping the ARRL can do it all is naive at best. Our representatives (and I use the term advisedly) in Washington need to know, with no diplomatic beating about the bush, that BPL is a disaster waiting to happen. As for posting to the "day trader" boards, if you keep in mind that you are talking to people with no idea of what causes radio interference other that "that Ham down the block." In other words, idiots, and tone your comments accordingly, it can't hurt.

If you have access to the members-only area of the ARRL web site you can see these and decide for yourself which would be best for you. I did a comparison and chose the Alinco DM-330MV, primarily for the variable output and the ability to shift the frequency of noise spikes, although mine is so quiet that I have yet to need this feature. The Astron SS30 looked pretty good also, as did some others. There were a couple of real noise generators, however. 72/73, Bob N7XY -- Bob Nielsen, N7XY n7xy (at) n7xy.net Bainbridge Island, WA http://www.n7xy.net ------------------------------ Date: Thu, 20 Nov 2003 14:17:01 -0600 From: Jim Giammanco To: qrp-l@lehigh.edu Subject: [161623] Re: Strange band condx Message-ID: <3.0.1.32.20031120141701.008af8f0@baton.phys.lsu.edu> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Someone.... please make a few minutes of audio recording of the sound of HF CW warbles by geomagnetic storming.

Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Now you have my interest up. Your secret is to have a counter that counts a frequency near 1000 Hz the SAME over a 15 minute period. Doesn't need to be real accurate, just stable I think. Have checked my Yaesu FT-817 and it counts on the front panel in Hz! So I should be able to correct the internal errors of the FT-817 with WWV to at least plus or minus 1 Hz. I will prove with math that the calibration of the radio, and the beat frequency oscillator and the counter will all not matter, PROVIDED all the errors remain the same over a 15 minute measurement period. There is nothing important about using the counter at exactly 1000 Hz read on the panel, except that it makes the calculations easier. Now I need to sit down back at my pad of paper and using the first proof that the radio reads out in one Hz steps continue with math. More later, and actual measurement of WWV at 10 and 15 MHz I hope. -- - Karl Larsen k5di Las Cruces,NM Az ScQRPions - ------------------------------ Date: Thu, 20 Nov 2003 14:37:08 -0600 From: "George, W5YR" To: "Karl Larsen" Cc: Subject: [161625] Re: Measurement methods.

I will include my reply to you here since others may be interested. ---------------------------------------------------------------------------- ----------- > Do you measure the 1000 Hz tone with a counter? What is the > accuracy of it? No, I let the frequency measuring capabilities of DigiPan do that job. The DSP processing in PSK31 uses a very sharp 31.25 Hz filter to select the desired audio signal and to track it. The DSP logic also measures the frequency of the signal. So, what is the ultimate reference? The soundcard . . . You check that the soundcard is on frequency by tuning in WWV in AM so that your receiver dial calibration doesn't have any effect. You select one of the tone signals in DigiPan and note its frequency. Tones used are 440, 500 and 600 Hz. If DigiPan says that the 600 Hz tone is 600.0 Hz, then you know your soundcard is OK. If it said 602.4 Hz, then you would know that you had an error of 2.4 Hz in your DigiPan readings and make a correction. Or you could on some soundcards correct the frequency. Makes a real quick way to measure any signal frequency. I used to use it as a "panadapter" to watch the Fox Hunts and keep track of the pack. But with the PRO2 Spectrum Scope, I don't need DigiPan any more for that. ---------------------------------------------------------------------------- ------------ George ------------------------------ Date: Thu, 20 Nov 2003 14:40:17 -0600 From: "George, W5YR" To: "Karl Larsen" Cc: Subject: [161626] Re: Measurement methods.

Hey George; No offense intended, but I think you and Ed *might* be very wrong on this. Certainly one can look to the fact that over half of the investment community is wrong at least 1/2 the time. This is a fact, because otherwise it wouldn't be mathematically possible to make money. I grew up around the investment community, and the sharpest ones (i.e. the ones who consistently made money) did NOT listen to "conventional wisdom". (They also didn't look like the multi-millionares they were.) Having said the above, I am also not clear exactly why something shouldn't be said. So far the ARRL has written some very course (according to them) and nasty letters. I think alot of REASONED responses could do no worse. If the investment community gets the wrong impression, they they loose some money. I personally think this should be decided at the spectrum management level. BESIDES, wide bandwidth solutions are the real answer, which ultimately leads to the microwave spectrum anyways. THAT is the real crux of the matter. But alas your and my input are just opinions, and we all have those. So no hard feelings about this, and let's part as friends.

Thus, I am pushing my luck by posting on this reflector! Maybe someone on here can steer me in the right direction. I'll make it short. I want to install a 70 volt line audio system in my lake house. I know how to wire the system, no problem. My problem is the amp that will drive the system. I have an old solid state stereo receiver (Yamaha R-8), 65 watts per channel and it uses silicon output transistors. I want to use to drive the system. I want to strap the 4 ohm outputs together and then feed the strapped amp into a 70 volt line transformer. Can I strap the outputs together without letting out the magic smoke? Or, could I use two 70 volt line transformers with inputs going to the amps two 4 ohm outputs and then tie the 70 volt secondaries in parallel? Or, if the above doesn't work, how can I accomplish my goal? (I know the above suggestions will isolate the two output's DC voltages, but what does the AC audio feeding back from one amp into the other's output through the transformers do to all this? That is my concern. I also understand the transformers must handle the power requirements they will be subjected to in the system). I'm sorry for the off topic post, but some of you guys are wizzards and I need a wizzard's advice. Thanks all for putting up with this. (I feel better now)!

Bruce, Evidence to support the idea of Earth's field changing in strength and polarity is found in volcanic rock and clay pottery. The pottery record goes back a few thousand years; the volcanic rock goes back quite a bit further. Records of sunspot activity are only a couple hundred years old. So it's hard to find a correlation - right now it's just a theory.

I've called CQ on CW numerous times with no results. Checking 6 meters occasionally as well with the same results. Right now - 23:55Z 40 meters is real good and has fairly low background noise compared to signal strengths.
