Now I begin to see the appeal of a web SDR - it would be great to monitor while I'm at work :)

Hi,
Yes the Hifer transmitter I’m running for PBJ is the KØLR one. I’ve been running with it since 2001 or so, and never had any problems whatsoever. It just works.

Thanks Sal. Am watching for you now. SIW is good and strong, and I'm already seeing bits and pieces of SJ too. We'll see what the next few hours bring.
If I might suggest, this might be a good month to operate nightly. Being the traditional best time for 1750 m DX, there are likely to be more folks tuning in randomly than at other times of the year.

Chuck,
Sorry so late on reply, but I just saw your post. Ron WH2XND and I are very close to operating on 75 khz. Our grants allow 68 - 76 khz with 10W ERP (yeah, right!). We both should be able to manage ~2W or so. I finished a couple W1VD design KW amps for 75K, and am now in the process of testing the LPFs. I'll be measuring my antenna for the matching network in a couple hours, and will be ready for operation soon.
It would be nice to have some company down there!

Here's the best SJ of the night, shortly before it began a long, slow pre-sunrise fade. What's remarkable about this capture is that SJ was strong enough for me to use Argo set for QRSS20 speed. Normally, I can only detect enough SJ signal to decode a cramped view at QRSS30 (see the other attached file, 0203dec-SJ2). WM and SIW both showed up nicely, too.

MLS Saturday Night
Between my EAR session and the one for SJ and companions, I spent about an hour and a half listening for MLS. Usually, it doesn't get strong enough until later in the night, but I was able to retrieve enough to display a very cramped ID at QRSS60. At top is the normal size Argo display at QRSS60, and at bottom is the result when magnified to double the size.

After last night's captures of SJ, I continued to watch WM and SIW into late morning and checked back on them throughout the day. Apart from a fairly substantial dip around sunrise, both signals maintained a fairly constant presence...until about 4:30 PM CST, when SIW faded away on the QRSS30 screen (shown here) and was just barely visible on the QRSS60 screen. That was half an hour before sunset and was no surprise, except that WM did not fade at the same time. If anything, it got a little stronger. Will check on that and see if SJ has shown up again when I go back in a few minutes.

Weekend HiFERs (Saturday)
Had the unexpected good fortune to be able to go to the farm and monitor this weekend...something that will happen very rarely this winter, unfortunately. On Saturday afternoon between about 3:30 and 5:00 PM, the watering hole offered up USC, EH, RY, and MTI at times. WV came in for a while after 4 o'clock, and I heard RF for the first time up at 13,564.03. By dark, the band was dying rapidly, with only EH and RY visible intermittently.
Sunday was interesting. I'll have captures from then in a later message.
Sunday Night SJ, WM, SIW
Posted by John Davis on December 04, 2017 at 06:31:21.
I reported earlier that SIW faded out about half an hour before sunset. WM did the same about 15 minutes later, but both returned right after sunset here. And, as you see, SJ showed up two and a half hours later, with a bit of temporary frequency drift. At the same time, WM was so strong as to exhibit mild dogbones.
All three signals experienced periods of fading during the evening. I'm currently trying for MLS, as it is often a creature of late-night. It'll have a tough time getting through all the QRM, but maybe it'll make it.

Thanks for your time in the field to snag the reception reports.

Posted by ed holland on December 05, 2017 at 00:55:07.
Hi Folks,
Good listening conditions yesterday, early afternoon Pacific time. High in the band, audible copy of GNK, RF and RQ were all noted at times, fading in for a few IDs and then sinking.
Near the 13,555 hunting ground, we there were several traces for a time, when using Spectrum Lab to pick out signals from the noise. WM, Both SIWs for a brief period and USC, the latter reaching clear audibility at times.
Alas, I did not have longer to listen and log, but conditions were great for listening here in northern CA.
Although I used the NRD 535 for the above loggings, I did spend a little time evaluating the NRD 525 to which I devoted considerable time to diagnose and repair. It turns out to be an excellent beacon machine (very stable) and shows a lot of promise for LF receiving work if I ever get setup for it.
Cheers,
Ed

In reply to Re: Weekend HiFERs (Saturday) posted by Mike N8OOU on December 04, 2017
HiFERs started out slowly on Sunday morning...at least, at the watering hole. Until 10 AM CST, only EH and RY were visible. Elsewhere, WV was astonishingly good for a while. So was RF, although for shorter time; and FRC was visible and about 50% audible.
About 10:08 AM, NC rapidly materialized out of nothing, and then at 10:10, USC started a slow fade-in. Soon, the Big Four were all present, and USC even dogboned for a while, producing a bit of audio intermod with EH that showed up just under the NC squarewave. Though not shown in this capture, MTI did appear a few times during the day and was audible a couple of times. No sign of the Illinois path all day, unfortunately.
In the afternoon, I took a shot at PCO and saw the characteristic signal at the right place. It was clearly keyed Morse, but with all the neighboring carriers I could not reliably decode it by ear. However, the presence of the signal prompted me to try for AZ, which I soon found. (The paths are not all that close, but I have noticed in the past that the presence of one sometimes hints that the other one may be available too.)
And, there has been a mystery signal at 13,555.350 that shows up as a few seconds of slightly distorted FSK square wave. My fist thought was IMD, but the frequency doesn't match any mixing product from the available stations, and it's also a lot steadier in frequency than NC or EH, the two most common sources of intermod. Anyone want to take credit?

WSPR for HiFers?
Posted by Chuck, N1KGY on December 08, 2017 at 22:24:36.
Any reason why most folks are not running WSPR for their HiFer beacon? It seems like a natural fit.
I'm wondering if anyone would be interested in a "WSPR Weekend" for 13.56~Mhz... we could turn (WSPRnet) reporting off and just posts spots here.
Just thinking out loud.
I have set up my U3S to run in QRSS-3 at 13.556.905 sending "MMK". I picked those settings because QRSS-3 seems to be the most common mode, and '.905 is clear of other users (listed here), and sounds reasonably clear at my QTH.
Of course, adding WSPR to it's cycle would bee easy - just add a config block for that mode/frequency and set it running.
The ultra-QRPp modification was easy - I just added a header which bypasses the BS170 final, and directs the output of the synth through a 10dB pad to the LPF instead (I'm using a standard 20M LPF). The synth produces about 2.2 volts of RF, which is about 44mW, so a 10dB pad should be about right to make it legal for Part 15 if I've done my math correctly - assuming an antenna with gain equivalent to a dipole.
The vertical antenna I have available to dedicate to it for a while is a 23' aluminum vertical with "fish tail" top loading, over a ground-mat of 2"X4" galvanized fencing which is roughly 12'X 25' in size, plus a 4' (lightening) ground rod. I'll match it with a homebrew L-Match made for 20/30/40M QRP-portable work which is presently sitting idle. It should perform about as well as a vertical dipole, so should be legal with the same power input... again, if I've done my math correctly ;P
Anyone want to offer any thoughts/corrections before I put this on the air?
Thanks, Re: WSPR for HiFers?
Chuck

In reply to WSPR for HiFers? posted by Chuck, N1KGY on December 08, 2017
I agree that WSPR-2 is a good mode for 22 meters, and I suspect the main reason it's not more widely used is that most HiFERs were put on the air with simpler transmitters that have not been replaced or significantly upgraded since then. With the U3S, though, WSPR is simpler and pretty economical.
Secondarily, there is the need to keep the transmitter and the computer at the receive end in reasonably close time synchronization, whereas QRSS, FSK, and CW can be copied whenever you begin listening, provided the signal is present in the first place. This, too, is no longer a big objection. Bottom line: it'd be great to see more WSPR signals on the air, either continuously or alternating with other modes (also not difficult with the U3S, Arduino, or Raspberry Pi implementations).
I would recommend double-checking the power calculations, however. The power represented by that 2.2 V measurement depends on the impedance at the measurement point. Given that P=E2/R, 2.2 V across 50 ohms is 96.8 mW, or 64.5 mW for 75 ohms; therefore, the pad would need to have greater than 10 dB attenuation.
Also, a monopole antenna at ground level does not correspond to the gain of a dipole. It actually has 3 dB pattern gain over a free-space dipole, because all its radiated power is confined to half the volume of a dipole. Thus, the correct input to the base of a monopole is just over 2.2 mW.
In addition, the 23 ft antenna is .319 λ, which has a slight pattern gain over a λ/4 vertical; plus some additional gain because of current redistribution caused by the top hat. However, I doubt that these two factors are likely to be significant in your calculation of the necessary attenuation, because ground system losses at 22 m will probably offset that slight advantage.
Hope that helps.
John

Thanks John, I knew something didn't look correct, but wasn't seeing my error. Chalk it up to being pretty darned rusty with the math skills ;P
Yes, FP will be made resistive @ 50ohms, since that's what the LPF needs to see. And 2.2v/50ohm = 44mA, not 44mW. So to bring that |~96.8mW >> 50ohm| signal down to 2.2mW I'm going to need ~16dB of attenuation, not the 10dB I presently have cobbled together... so back to the bench to sort through resistors.
Also, I wasn't thinking of the antenna as a monopole; I was treating it as a close analog of an EFHW, and thus assuming "unity gain ref. to a dipole" - but you're right, elevation of the current loop is nowhere near high enough AGL to think in terms of free-space gain, and I totally overlooked the ~3dB of gain caused by ground reflections. Again, thanks - I should know better than to be hasty and 'ballpark' the math in my head, especially when I'm tired and in a hurry. I'm going to fire up EZNEC this afternoon and make a rigorous evaluation of the antenna before I go further, and also verify the RF voltage after the LPF on the 'scope, so my attenuator will be spot on.
Now, if I could just get some relief from the constant 'womp womp womp' of CODAR on 13.55xMhz I'd be a happy camper. I'm close enough to VA Beach and the Outer Banks that it is S9+30 ~ +50dB most days, here.

Amen. Here in the middle of the country, we don't get any one CODAR rig nearly as strong as you do, although we do get them from both coasts at once on a good (bad) day. The one ray of hope is that all their experimental licenses expire in less than five years and won't be renewed, thus requiring a move to the bands which have newly been created for them.
One of those is just below the 22 meter band, so if we get to missing the old familiar racket, we can tune down a few kHz to get our fill again. ;-)

David,
I'm seeing no 60Hz mixing products from your signal tonight. Previously I've seen as many a four decodes, and additional spurs which were outside the 1400~1600Hz window, but not tonight. Your signal does appear to be just at the threshold of overmodulation when I look at it in ARGO - not severe, but just at the threshold of "spreading". See attached ARGO grab - your sig. is at 1453Hz.

Re: sidebands
Hard to say without knowing more about your amplifier. Given the previous 60Hz images, I'm guessing it's a tube amp, Class C, and running a pair of 24G/3C24s in Push-Pull?
Lots of NDBs in the <=50 watt class ran just such a PA. I've worked on many of them.
Now, running Class C, the grid impedance changes as the exciting signal rises above 0 volts, and grid current starts to flow. If there's not quite enough drive power, then the signal will get 'mushy' or even flat-top in the peak of the RF cycle as a result.
"Not enough drive" is common when a toroidal transformer is used to drive a tube amp from a solid-state exciter. The toroidal transformer is used to step up the voltage of the driver to the tube's drive requirement(typically 120 to 140 volts [peak] drive for 3C24s in P-P), but in doing so it also reduces the available drive _current_. Since the grid impedance is nearly infinite while the grid is negative, drive current is <1mA in this portion of the RF cycle.
But when the grid goes positive at each peak of its swing, the drive current required will go up, and so an exciter which is under-powered will produce "soft topped" drive during the 20 to 40 volts of peak positive swing.
Interestingly, reducing the (negative) grid bias to try and increase output from a PA which is under-driven in this fashion exacerbates the problem - with less bias, *more* of the drive signal will be in the grid-positive region, and severe distortion will often result. The closer you get to Class B operation (0 volts bias) the more driving power such a PA needs; conversely, the greater the (negative) grid bias, the less drive power is required.
If this applies to your situation, then the 3C24 tubes should have **at least** -60 volts of bias, and run cleanest at between -70 and -75 volts when the plates are at 1000 to 1200 volts, and plate current should be 75 to 80mA for a {max} output of 55~65 watts. For the 3C24, 90mA is the Meltdown ***MAX*** value of plate current for a P-P pair. Derate appropriately if your plate supply is ~800V: 60mA to 70mA is your target - that's 50 to 55 watts input, which would produce 35 to 45 watts output.
Less is more, and cleaner is better - set the bias for -72 volts and take what you get from that for now. Adding another BS170 (or two) to the final in the U3S and increasing it's (PA only) supply voltage to about 7.5 volts will double the drive power available to the 3C24s - then you can leave the bias of the PA at -72 volts and still get a clean, solid PA output of 50 watts. No mush, no fuss.

Chuck Re: sidebands

Re: WSPR for HiFers?
It's about impossible to receive HiFers here, John. Even with a very tight BPF in front of the RX input, when it's right on 13.52~13.57 there's no blocking it, and it's deafening. I'm looking forward to it going away... at which point I will probably get more into that aspect of the hobby.
LowFer / 136Khz / 475Khz transmitting is as impossible to do here at the house as HiFer receiving, because while we have a good sized piece of property, it's mostly covered with large hardwood trees except for the side where I have a 12K8 utility run - there's no clear area for a Tee-Top or Inverted-L of any respectable size unless the top hat is right in among the branches, and we know what that costs in losses. That's why I need to do the remote setup for my MF/LF transmitter at our AG property... which is proving to be more of a challenge than I anticipated - I can't quite reach it with a WiFi link (as I planned to), and while UHF portables are cheap enough these days to use for a control link, I still have to code up an actual control program - either ion an Arduino or a Raspberryi-Pi - to translate everything to/from discretes at each end.

I have put one of my SDRPlay receivers on 137.000Khz/USB, passing audio from 100 to 900Hz, so watching the top of the band for activity with HD-SDR. Lots of QRM lower in the band, but above 137khz looks workable -- now that I've chased down as much of the switching PSs and other noise as I can ;P

Will keep watch here through tonight - with the exception of 0025~0055Z when I have a net that will interfere - if anyone wants to try for copy here in Eastern Carolina (FM06).
Can QSY by request here on the board - will keep an eye on it tonight also.
I see a strong and steady carrier at 137,695.32~ but other than that, both HD-SDR and ARGO show nothing but noise at present.
Will post grabs of anything interesting.
Hope to see some activity this evening...

Lowfer SIW back running as intended
It took awhile to recover from the damage of a 3.3 V regulator deciding to put out 12 Vdc. Got a new synthesizer kit from Hans plus a new TCXO to drive it at 27 MHz and installed them Saturday. The schedule calls for QRSS30/60 at 185.2993 kHz on SA and SU with switch to 185.185 kHz WSPR15, QRSS25, Opera32 on MO around 1800Z. Apparently that went okay because I'm copying the signal now on 185.185 kHz and just got an opera32 decode. Hopefully things will keep working because it's getting awfully cold for outside repairs, hi.

BitX released a "general coverage" 3~30Mhz transceiver.
All the HF bands, SSB and CW (built in keyer, too), 10 watts output <=10Mhz / 7 watts up to 21Mhz / ~2w on 28Mhz -- pair of IRF510 finals
Uses a "Raduino" controller board with Si5351 synthesizer. Software for the Raduino is open source, so you can hack away if you wish (or just keep the factory installed version)
Comes complete, minus enclosure and speaker -- $109

Thank you for your reply. I had no idea that WSPR is so sensitive to 60 hz but now it make sense. I was using a 99 cent power supply from goodwill that must have has a slight ripple.The power supply is rated 4 amps at 12 vdc not bad for 99 Cents. I went to choke feed hoping it would stop the side bands.So far so good!!! I love experimenting and building from scratch.

Sorry to have not had a chance to post before now, but it's been a busy week. A fortuitous combination of good weather and doctor visit changes enabled me to go to the farm for a couple of hours Monday afternoon. Both LowFER attempts yielded some surprises, as I had not yet seen Garry's post about SIW before leaving, nor Mike's email about a specially requested change for testing.
Thus, I found WM 1 Hz higher than usual, and in FSK-only. He returned it to normal later. Meanwhile...
SIW has returned to operation on its alternate frequency of 185.185, but in the daytime that turns out to be a rather noisy spot here in SE Kansas nowadays. Alas, it may be quite a while before I have a chance to evaluate it at night.

David, I saw the 60hz sidebands on your WSPR above and below shortly after posting here. Doesn't look like the power supply choke worked. It's not RX overload here, I switched in attenuation and while I didn't get decodes all the time, the side bands were visible on my display. Are you using a the U3S stand alone or with an amplifier?
Have you tried running the unit on battery power? I'm just trying to address the WSPR sideband issue.

I've built a QRP Labs receiver module. It is your pretty standard SDR like a SoftRock with I/Q outputs.
It seems to perform well with HDSDR. It also has the option for a plugin polyphase module to receive USB or LSB only.
I want to use it with ARGO for a dedicated HiFer RX.
Can ARGO work with an SDR I/Q RX? I've researched and it appears it has been used with SDR dongles. I have only used ARGO with a normal USB/LSB RX. If it does work, does it want I or Q? I have tried the QRP Labs RX with the polyphase module but it seem to work better as an I/Q SDR with SDR software. Maybe the answer is out there and I missed it.
Advice welcome.
I do have a U3S I'm just finishing. I plan to try it on 22M WSPR. Don't know who will be out there listening but WSPR seems like a good fit for 22M.

Hi Bob. This is the dilemma with most software dependent receivers. (I reserve the term "software defined radio" for those whose DSP capability is self contained but can be reconfigured by communication with the outside world, not those totally dependent on an external computer to yield a usable output.) Their I and Q outputs each include frequencies both above and below the local oscillator frequency aliased together into the audio spectrum...no problem for a decent sound card and suitable algorithms to sort out their phase difference into USB or LSB with lots of unwanted sideband rejection, but if you directly use either I or Q into Argo (which is not able to accommodate I-Q together), you'll get wanted and unwanted signals overlaid.
That's why the polyphase network is available for the QRP Labs kit. It may not be able to perform unwanted sideband rejection as perfectly as a precise mathematical algorithm, but it does avoid the need for two soundcards.
That is your other option, by the way: a computer with two soundcards, one for the I and Q inputs that your SDR software uses (or else a receiver with digitized I and Q outputs that your software package recognizes as if it were a soundcard), and one that outputs a digital stream for Argo to use, plus a software connection between the two. That last part is something I'm not familiar with, but I believe others here are.
By the way, if you get into monitoring WSPR at 22 m, your QRP Labs receiver will probably be a fine performer because the standard WSPR 2.1 software supports I-Q audio inputs (although I don't think WSPR-X does at this time).

Bob,
As John Davis explained, Argo cannot handle the I and Q inputs. But, Spectrum Laboratory certainly can, though at the expense of a lot of cranial capacity to get it set up! You can null the opposite sideband within the program, and then use any mode supported by Spec, including QRSS, of course.

SDR Dongle Drift
Posted by Frank Lotito on December 18, 2017 at 02:47:46.
Can anyone comment on SDR dongle drift? My dongles leave something to be desired w.r.t. drift starting from a cold start-up. I have not kept them on long enough to see if they settle down "good enough" for 22 Meter 5 WPM beacon reception, yet alone for QRSs beacon reception. My $$$ Radixon WinRADIO "Excalibur" WR-G31DDC is definitely in another class well above the simple dangle from the computer's USB port receiver. 73 Frank K3DZ / WH2XHA
Re: SDR Dongle Drift

In reply to SDR Dongle Drift posted by Frank Lotito on December 18, 2017
You are definitely right about them not being anywhere in or near the same league as your Excalibur.
Call me prejudiced, perhaps, but I have trouble bringing myself to dignify any dongle with the designation "SDR." Remember what they originated as: cheap software driven downconverters for digital television reception, built to a price point rather than for performance. Frequency stability was not a prime concern, so their L.O./clock driver is generally based on the cheapest available crystal oscillator module. Nor, for most of them, is dynamic range a big concern with such low bit counts that most of their ADCs offer.
Dongle "SDRs" are the dancing dogs of technology...the wonder being not that they do the job well, but that they do it at all. IMO, their only value is as comparatively inexpensive demonstrators for SDR principles, although there are kits out there now that aren't particularly high-dollar either, but provide far more credible performance.

Thanks John!
I did try an experiment where I ran ARGO with a known freq signal and got results. My test sig was 2.6KHz below my SDR LO and low and behold, ARGO showed it at 2600 Hz. So I guess I would have one at +2.6 and -2.6 KHz from LO and that would correspond to I and Q? So which one I see is dependent on weather ARGO is looking at the left or right (I or Q)channel only.
John TAG mentioned using Spectrum Lab which will take I/Q inputs. ARGO is easy Spectrum Lab not so.
I'll play around. That's the joy of this!
TNX for the 22M advice. I was aware that WSPR 2.1 could take I/Q. I will try that.
My main interest in ARGO was for QRSS. If something else can do that, I'd try it.

Bob,
Let me first declare that I run Linux as my primary OS, I am not up to speed on the latest -greatest Windows. In linux you can simply re-direct the decoded audio output of your SDR control program (HDSDR maybe) to the audio input of Argo. That capability is delivered as part of the OS. I believe in Windows 7 you must purchase additional software to do that, I think it is called "Virtual Audio Cable".
In your test of inputting the I or Q stream into Argo, I believe you will find your signal at +2.6 on either line. What determines whether it is +2.6 or -2.6 is the phase difference between the two lines. That's the magic that a program like HDSDR performs.

Long wave broadcasting in Canada and USA
Posted by Scorpio on December 21, 2017 at 04:11:22.
Hello everyone!This is my first ever post on the LWCA Message Board!
Years ago, I had dxed the long wave band from 150 - 530 kHz when I lived in the northern part of the province of Ontario, Canada - now livimg in eastern Ontario and don't dx as much as i mostly do FM. I've heard many non-directional beacons along with European broadcasts between 150 - 200+ kHz. Re: Long wave broadcasting in Canada and USA
I noticed there are mostly NDB's on the LW band so I'm wondering why Canada and the United States and South America never used the LW band for broadcasting like they do in the European countries? They can be used in larger cities like Toronto, Ottawa, Montreal, Vancouver, New York City, and many others where the medium wave and FM bands that are being increasingly crowded with radio stations!

In reply to Long wave broadcasting in Canada and USA posted by Scorpio on December 21, 2017
I'd say the main reason that the LF spectrum was never used for AM broadcasting is due to the high summer time noise levels & the resulting need to high transmitter power required to make themselves heard above it.

Had the chance for a little festive listening over the weekend. Christmas Eve proved rather fruitful.
GNK, RF, but no sign of PCO on the high section of the band.
Lower down, Spectrum Lab helped to find WM, MP, USC and NC, possibly also a hint of an SIW.
Meanwhile, on the workbench, the Philco project saw more cabinet and electrical restoration work. This project is almost complete, and just needs minor wiring and final chassis assembly before gentle power up. Jumping forward in time, I found I (think) the issue with the Icom R72 receiver that was causing it to forget clock and memory settings - backup battery holder never properly soldered. Another internet bargain is saved :-)

Hi Joe, Re: ARGO with SDR's?
I received your very strong 137.777 kHz signal here in New York at FN21wr early this morning. Thanks for transmitting the very appropriate message! I have a nice ARGO plot I could send you if you could tell me some way I could get it to you.

Hi Bob,
I use ARGO with HDSDR frequently.
1. Install any virtual audio cable software. I use VB-Audio Virtual Cable.
2. Launch HDSDR and click the Soundcard button in lower left or hit F5. Select CABLE Input that should also have the name of your virtual audio cable. Click OK button to close window.
3. Launch ARGO. Click on Setup menu and select "Select Sound Card...". There you should be able to select CABLE Output which has the name of the virtual audio cable software. Click the OK button to close the window.
That should do it. Whatever is sent out of the HDSDR audio output will be input to ARGO and properly displayed. I run HDSDR in USB mode with the Tune value set to a round number frequency below what I want ARGO to cover. It works very nicely. You can also use the same method to simultaneously connect HDSDR to both WSJT-X and ARGO. Re: 2200m qrss
Have fun!

Thank-you for the report, Larry. Delighted to hear that the sigs are making it
out west!
Tonight there is a CW beacon on 477.7 kHz that might be of interest.

Thanks Larry!
I will give that a try. I just got my U3S working and I'm on 40M QRSS now.
I'm working my way to 22M and should start some experiments up there soon.

Jerry, I didn't mean to be so rude and "anti" sounding last Summer when you offered me to partake in net Saturday on 3927, but I decided earlier in 2017 to go the "Vince Pinto Route" and near totally ***bail outta most radio/technical hobby stuff**, including natural radio. I fondly retain love of DXing and radio but I am cutting it al back by 95% to do other things like study languages and work on a few inventions without much distractions. Secondly, I am moving away from the horrid southern Owens Valley to saner location not attacked by military aircraft of all kinds - I'k tired of living in "Inyostan" County-of-war- Kalifornia. Kalifornia will be toast too, soon. Time to sdplit crazy/kookyTaxifornia for saner pastures far away...
As such, I'm giving away ALL of my LOWFER WESTERN UPDATES in binders with my noites, etc. Mike Mideke and Jim Ericson published back between 1985 and 1992.
Although I have always been loather to post anything to this board because e-address ARE VISIBLE and thus spammable.
As the LWCA has seemingly never adopted a private messaging system not displaying e-mail addresses, I never have posted to here until this morning - the LAST day of a generally crappy year (for a lot of people - go figure...).
As I am in the midst of this big purge (most of my Ham Radio stuff goes next on eBay), if anyone would like printed originals of all the WUs I have (#58 onwards) and other stuff pertaining to lowfer xmting. LF was never workable from this land-locked nasty Owens Valley of Kalifornia, as groundwave cannot get out of the too-rugged terrain, only skywave, but my property is so hammed in by RF-sucking/soaking Tamarisk Trees (nasty dirty bug/vermin-breeding trees - a invasive species I'd like to see eradicated but full of 'em in Keeler/Keel-over, Kalifornia) that suck 90 dB from my LF signal xmtting - 15 watts input gets me less than 10 mW ERP out to the far-field - or maybe 1 mW ERP, so it is quite hopeless to try compared to the glory days of the mid-late 1980s when it was all analogue and people actually LISTENED with their ears live for DX rather than watching yet another computer screen. So alas I find most radio DX stuff in 2018 no-fun. I'm OK with spectrograms and waterfalls but I like listening with my EARS too - live CW - no digital junk, really. Old School there. So Please contact me at my (N6NKS) contact info on QRZ.com etc. etc. and let me know if anyone wishes a big bunch of radio binders from the 80s HEYDEY of lowfering when we all were trying for Trans-continental DX and messaging (pre-internet) and I still hole the DX record for a legal Part-15 lowfer - Mike's Z2 as heard in Kauai, Hawaii Janury 1986 (on my site too) Z2 was Q-FIVE! 10 watt coastal NDBs at the time were huge in Hawaii. A lotta fun, but time passes.
OK time to zap this out - good luck to your all - we're all gonna need it in the ongoingUS-cultural-wars/factionalization of 2018... Steve McGreevy
