Laurence & All:? ? After looking at the visual results Laurence experienced, it seems plausible I had a weak in & out of noise detection of SAQ, similar to how I see

WM partial traces on 185.3 when SIW is good visual copy.... BFO set at 500 Hz and QRSS1 mode in Spectran.? E-probe to 300Hz LPF to 17.2 kHz bridge tee diplexer to

ZFY-1-S level 23 mixer....3.0MHz IF

https://www.dropbox.com/s/lynh2dasr9gin8s/SAQM118.JPG?dl=0

Just afterwards I tuned up to NWC at 19.8 and the 100Hz MSK signal was 10 dB out of the noise or better. I see a similar level currently for NWC on the KL7L VLF
grabber.?

This VLF rx session is very encouraging. I never have received NWC that well prior to the added grounding improvements to the e-probe (two added ground rods in french drain pit) and the 17.2 kHz diplexer between the LPF and mixer...

I threw the diplexer together last? night using a 470uH molded choke and a parallel pair of .1uf poly film caps that were more like 9.5 vs 10nF meassured. (XL and Xc 50 ohms at 17.2 kHz). Insertion loss on the diplexer was?1.5 dB with the molded chokes, I should have wound them on FT50-77s....likely the insertion loss would go down a dB or so....

Similar e-probe to 300 kHz LPF to 75 kHz diplexer and mixer was used successfully on XND here over most of the winter.? The e-probe usually? did better than the EWE.? Only towards?end of LF season did the EWE start to work better than the e-probe on XND for 75 kHz...

I was glad to receive the special VLF transmission from
Grimeton Radio, SAQ, that took place at 10:00 UTC today.
Good signals reported throughout Europe.

I used a Perseus SDR receiver tuned on 17.2 kHz and an
ECO HF vertical antenna. The signal was relatively strong
with good SNR.

I only have a couple places in my yard where I can put a receiving longwave
loop antenna. The antenna I am building is 5 feet on a side with a
supporting cross made of pvc pipe. The top of the loop including mounting
pipe is about 9 feet off the ground.

One place I can put the loop is fairly close to a power line. I'd like to
avoid that spot if I can. The other location places the top of the loop a
few feet from an AT&T DSL phone/internet line (not directly under it).

I am wondering if anyone has any experience with placing an LF/VLF
receiving antenna close to a DSL phone line. I don't know if the wires in
that line are surrounded by a shield, but I suspect they're not.

I suppose one possibility to test the locations(s) is to take my FT-817ND
with a small antenna and put it near the phone line. That radio will
receive down to 100 kHz. But if anyone has had problems with some similar
arrangement in the past, it would help.

Zack:? I can close couple the 2M rubber duck on the FT-817 to sniff LF/MF noise on/near conductors such as branch circuit wiring, phone line, Ethernet cable, metal downspouts, etc.

?An AM transistor radio set to the bottom of the dial may offer some manetic sensing? help, although I think you have a strong local AM station station at the low end of the band that may drive the AGC over the top..? If you come across an early 1960s Zenith 755, 780, or 790 those radios have a 6 inch long by 1 inch wide?ferrite antenna and they have really excellent sensitivity when re-habbed.? The 780 and 790 have the LF band and a switch that disables the AGC and at the same time turns the audio volume control into an RF gain control.? Those are great mag antenna noise sniffer radios...The 755 is AM band only, but has the same large ferrite antenna without the DF mode and RF gain adj feature... they are lunchbox size and much more manageable than the larger? transistor transoceanic versions.... all metal chassis and built like a tube radio with transistor sockets. Those are POSITIVE ground radios using the old germanium transistors. Very clone-able from? hamfest or ebay parts radios...

Maybe watch SM5BSZ's "Sensors" youtube videos on LF noise sniffing....

While this may not be directly relevant to your question, it may be of 
interest to others.

I have DSL (via underground) and do LF/MF listening and the only 
problems that I've seen from the DSL modem are from its switching power 
supply:? I can't say that I've seen anything from the switching 
regulators within the modem itself.

I cracked the case of the DSL modem's wall wart (I'd done it anyway - 
the original electrolytics lasted only about 24 months, anyway) and 
inserted some small >=100uH molded coils in series with the AC input 
leads (they now function as additional fuses!) and also cut the DC cord 
very close to the wall wart and inserted a bifilar choke (a pretty hefty 
one of several hundred uH in each winding to handle the amp or two that 
it pulls at DC - but winding lots of turns of the DC cord on a hefty 
ferrite core would have also worked) and some large-ish, low-ESR 
capacitors across the DC to help enforce common-mode and suppress 
residual differential RF currents.

The result is that I don't really hear it on LF/MF unless I tune 
directly to the SMPS operating frequency - but even then, it's weak:? 
About the only place that I hear it is on HF - very weakly now, if the 
band is very quiet - due to direct radiation from it as this wall wart - 
and the DSL modem - is mere inches away from the window line feed of my 
HF antenna and the balun/antenna tuner.

* * *

I Can't "hear" the DSL modem's carriers on any LF/MF/HF frequency and I 
don't bother the DSL modem (other than a few lost packets) when I run 
full legal power on 80/40 meters - but I can knock it down with >50 
watts on 160 meters with the antenna running in "top-hat Tee" 
configuration (again, feedline is inches away) but it's not bothered at 
all when running 50-80 watts of RF on 2200 or 630 meters from a loading 
coil just inside my window (e.g. several kV of RF on the wire that runs 
within a foot or so of the modem): I'm thinking of moving the modem 
somewhere else in the house other than inches from my big tuner to help 
mitigate its effects when I run 160.

* * *

The biggest improvement to LF/MF noise mitigation is the fact that the 
ground of the coax on my LF-400B E-field whip is bonded to the metal 
roof of my house and there are two large ferrite chokes on the coax 
feedline:? One of several hundred uH near the antenna, with the 
antenna's coax shield bonded to the roof on the "antenna" side of that 
choke and another choke of several mH just where it comes inside the 
house (RG-58 on a TV flyback core) with the coax shield of the "outside" 
portion of the (e.g. "before" the choke) bonded to a (very!) nearby, 
"quiet" Earth ground.? This seems to be very effective in preventing 
"house noise" from being being conducted to the E-field whip - and the 
metal roof with its overlapping seams (not intentionally bonded, but 
possibly touching in a lot of places - and many, many square inches of 
overlap to capacitively couple to each other) screening the whip from 
the inside of the house doesn't hurt, either!

* * *

Finally, when I first got DSL many years ago I was running 256k on a 
28k-foot loop - right at the edge of where they would offer service.? 
Originally, the service was marginal, but I was able to get a few dB 
better S/N when I got the phone company to install a "whole house 
filter" in the network interface (NI) box outside to avoid issues with 
stubs and taps of the internal house wiring.? I also home-ran a short 
length of CAT-5 from the NI to the DSL modem.? I was then able to get a 
few more dB when I wound a length of that same CAT-5 on a large piece of 
ferrite (a discarded TV yoke) near the modem which seemed to slightly 
improve its longitudinal balance and prevent it from being knocked down 
easily when I run HF.? Almost 20 years later, I now have 40 meg DSL from 
a nearby DSLAM, but it still uses that same home-run CAT-5 from the NI 
on the TV yoke choke.

73,

Clint

KA7OEI

P.S.? I doubt that the under-hung wires are shielded, but if there 
happens to be AC power distribution on those same spans, I'd worry about 
that.? FWIW I read somewhere that the FT-817(ND) is deaf as a post below 
about 250 kHz - and performs worst down there with the preamp on (e.g. 
IPO off").

The ultimate test, of course, is to just test it.  What you speculate 
may be an issue, may not exist at all.  Power lines are more likely to 
be an issue than the AT&T DSL/Phone.  I have that service, no issues 
noted with the service down to LW Broadcast, slight issue with noise 
within a couple feet of the modem into VHF.

Had a bunch of WSPR-2 decodes on 2200M last night from our camp in Maine 
(FN43sv). They didn't upload due to an issue with the ancient laptop 
(since fixed with a reboot).

WH2XXP 28 decodes.
WH2XND 37 decodes.
K3MF 18 Zillion decodes, continuing in the daylight.

Sorry I wasn't there to join the fun, either as a transmitting or
receiving station. I'm curious how my decodes would have compared as
I sometimes get the sense I don't hear as well as I might.

The wooden base for my "portable" receiving antenna ripped apart in
a wind storm several days ago. I'm in the process of building a new
and improved version but short on time. The LNV laying in grass
definitely doesn't hear well at all. :-) When I get the new base
done, I'm going to experiment with moving the LNV around to see if
location relative to other antennas and houses appears to make any
difference.

Navtex monitoring has been the pits this past week, so I thought I?d try out another
digital mode and frequency for Saturday and Sunday nights.  I?ll be watching for
any WSPR-2 activity on the 2,200 metre band with 136.000 kHz. USB dial.

Sorry I wasn't there. I am still down pending station upgrades. I
have very little time to work on radio projects this time of year,
so progress is slow.

JB & All:? The QRN started to increase from t-storms to my SE just after this early afternoon EAR capture...? I was? seeing an occasional -66 SNR? om the carrier above? above EAR during fades...

At one point I was seeing -53.6 on EAR in this session...

https://www.dropbox.com/s/rwo61tzw8f20eb1/EARM3018.JPG?dl=0

12 to 15 dB out of the noise on my NW EWE antenna is my best guesstimate...


Likely my rx is a few tenths (.2~.3) Hz on the high side...

Hi Mike?.thanks for the report and nice Argo screen shot.  Propagation can?t be too bad to get
the numbers you did.  My Navtex monitoring in the past week has been very meager, with only
two 518 kHz. stations over 1,000 km logged on one of the nights.

Subject: [Lowfer] EAR tests this morning & early afternoon
Message-ID: <163a837f8dd-c91-2349@webjas-vad123.srv.aolmail.net>

JB & All:? I thought I would try some e-probe vs NW EWE tests before the afternoon QRN took over the spectrum.

First image below is my e-probe antenna driving a 300kHz LPF and then into a 2N3904 common emiiter preamp with a 470 ohm collector resistor and 22 ohm emitter resistor,? (via a pair of 185 kHz bridge T diplexers before and after the preamp)

Gain of 470/22 = 21 or 13~ (supposedly).? If I add the 100 ohms or so from the preamp B+ chokes the gain is more like 570/22 =25.9? and 10*log(25.9) = 14.1 dB....

So here is the filter>preamp>converter arrangement...

https://www.dropbox.com/s/popp6fe8uo02quh/IMG_1206.JPG?dl=0


And here is the e-probe capturing EAR...note the green bar level on the left....

https://www.dropbox.com/s/thi59jju1j8174k/IMG_1197.JPG?dl=0


Now I switch to the NW EWE antenna....

https://www.dropbox.com/s/z60f3v9g3raw4hh/IMG_1198.JPG?dl=0

Note how the e-probe is showing a -50.8 peak and the NE EWE antenna is showing a -54.6 peak, yet the background noise is lower on the NW EWE and EAR is visually stronger...

Now I switch to the e-probe antenna through the filters without the 2N3904 preamp and the prior two captures are on the waterfall as well...

https://www.dropbox.com/s/nvidvxfmixbwe88/capt00003.jpg?dl=0

At this point I will mention the combination of the 300 kHz LPF with the 185 kHz bridge T diplexers before and after the filter have a combined insertion loss of?
.6dB as measured with my Wavetek signal generator set at 188.83 kHz and Boonton RF millivolt meter....

In all these tests the AGC is off and the preamp is off on the FT-817 with the IF dial frequency 3.188.83 MHz? (3.0 MHz converter LO)

I can bring up the e-probe visual trace somewhat by turning on the FT-817 internal? preamp to increase the system gain, but it is not quite enough to make up the?
total background signal level to where ARGO works optimally for visual trace display.? It seems that ARGO really "likes" to operate well with the green level meter set at about 1/2" tall for weak signals and background noise...


I picked-up and SDRPlay RSP1A at Dayton, so here is my view of the AM Band on my e-probe with no filters other than the RSP1A AM band internal filter-attenuator and the LC shunt in the e-probe input which I have set near 1020 kHz (which take the? very local 1020 kHz and 1080 kHz AM stations down about 40 dB). Otherwise the e-probe is a single fet J310 W1VD modified AMRAD circuit....

https://www.dropbox.com/s/rqnxedgtvn6m212/IMG_1202.JPG?dl=0

Here is the e-probe and 300kHz filter-diplexer-preamp-diplexer combination with the RSP1A set at 273.0 kHz, which is the strongest local NDB station (UCP, New Castle, PA)...

https://www.dropbox.com/s/0g6xkew2znuw2dl/IMG_1205.JPG?dl=0

Having all the local AM stations down at -100 dBm or so seems to help the weak signal chasing for me...

Next thing to try is to roll the 2N3904 gain back a bit more, (another 2~3dB, etc.).? Going from a 4 ohm emitter resistor to a 22 ohm emitter resistor made a 1 S-unit improvement in my poor-main's 500Hz switched Zener noise source-to-variable attenuator setup in AM envelope detection mode with the FT-817...

After a lot of effort my 137 transmit is ready for a test.
It will be running WSPR2 overnight at least (unless there is a failure) on 137.450. EIRP is estimated to be in the range of 500mW. I will not be able to receive during this test run.
All reports appreciated.

Hi Mike, LowFERs?.you were a busy boy doing all of that testing!  It clearly shows that for EAR, your NW EWE antenna
is the winner.  Would you share with us the details of your 185 kHz. bridge T diplexers?  Thanks for the report and the

JB & All: Actually I was more interested in seeing how well the e-probe would perform not being overloaded by the 1020 and 1080 kHz 50KW stations at

4 and 5 miles away. It took several adjustment? iterations to get the LC shunt on the e-probe input adjusted to get ~40 dB notch on those two powerhouses.? The LC shunt also?reduces the 730 kHz station several dB.? The e-probe gain seems to return to normal around 500 kHz and down....I expect the directional EWE to win, but each antenna has?its strengths and weaknesses...

The 185 kHz Bridge T Q=1 Diplexer simply has??all XL, XC, and R values at 50 ohms at the design frequency. Info and measured insertion loss below...

https://www.dropbox.com/s/wt8bjc02tl4jwzg/185DPXR.jpg?dl=0


Somewhat analogous to a "bidirectional"? isolator at microwave, it has a very good 50 ohm broadband match with some band pass filtering at the design frequency...

Thank you Joe Reisert W1JR who originally wrote up the Bridge T diplexer in Ham Radio magazine years ago....

Thanks to all those who listened for me and for all the WSPR reports.
The S/N's reported were on average less than I expected based on the results of previous runs. I am hoping this is due entirely to current conditions rather than the minor changes I had to make to the antenna to get it weather resistant.?
This teat run was successful in that it pointed out a number of deficiencies in the system that need to be addressed before trying to run a 24/7 TX/RX system.
Back to the workbench.
Thanks & 73,

I am working on getting at least a new receiving loop going at the location
I moved to a couple years ago. I've been without any antennas at all until
I recently put up a multiband vertical. Now assembling an LF receiving
loop, 5 feet on a side. I hope it works well.

I have been experimenting with magnetic loop antennas and am now operating
portable on 160 meters. I note that a 250' long conductor in a magloop will
radiate a signal on the 600 meter band with a efficiency of 25% so 4 watts
into the antenna gets you 1 watt eirp. My magnetic loop is made with 2 inch
wide strips of aluminum flashing. The strips are pop rivited together using
20 rivets at each join and the heads and bases of each rivet are soldered
to the aluminum using harbor freight aluminum solder. On 160 meters I
recieved a report of s-9 for a qrp contact at 5 watts ssb with a 100' long
strip of aluminum. Please note that this length is MUCH longer than normal
for a mag loop, but it works really well! Pictures are on facebook- san
angelo amateur radio hams. The magloop was in a delta shape for easy
installation. the feed was a gamma match using 20' of wire wrapped around
the conductor and then grounded to the aluminum at 20' from the apex which
was the coax ground. I tried feedloops but had no luck as the swr's were
very high. The gamma match worked the first time.

Is that the triangle-shaped antenna?

Curious how you determined the efficiency?? N6LF comments in his 630m 
antenna notes that a "small" loop (ie. mag loop) has a theoretical limit 
of 4.2%.

Also, don't forget that you have to account for antenna gain in EIRP 
calculations.? If you really are getting 25% efficiency, and a small 
loop has 4.82 dBi perfect-ground gain which is a factor of approximately 
3 (or you can use gain over real ground if you know your local 
characteristics at MF - different than HF), then 4W TPO would result in 
3W EIRP.
