Re: New Lowfer Transmiter/Loading Coil
Hey Ed, I am not sure what the value will be. Im making the antenna 35 to 40 feet tall with 10 food diameter top hat. Its going in my back yard and a have some trees around it so i don't think any predicted calculations will be right. I'm going to start winding a tapped coil around a 1 foot diameter and watch the voltage and current on the scope. After i get an idea i'll work on makeing it adjustable. I would think it would be aroud 2500uH??? Re: New Lowfer Transmiter/Loading Coil

Hi John. Whew, that's a lot of uH's, but I guess down at LF it's required with a short antenna like 35-40ft/11-12m. Much more than in the 400-500KHz MF range. Thanks for the info on the antenna installation. Ed WSlidell,LA EM50cg

I am in the process of putting up a 500 Khz antenna and decided to build an antenna analyzer that will do the LF and VLF bands. I used the Aussie analyzer as a guide and after lots of weird problems with parts (that I have never seen before) I have it working very well. I plan to put it in a box this weekend and install battery pack to make it portable. (I dread makingthe cutout for the LCD display)
It is a 2 bander and will do 125 Khz to 1.9 Mhz in two bands. I am very impresse4d with the design and it looks like MFJ used it as a guide for their analyzers. The design is very well documented.
It would have gone very smooth - but for a 50 ohm .1% resistor from newark actually being 50K and a really weird 5 volt T092 regulator happily putting out 7.3 volts. The regulator was one of two I had in a batch of 100 from Newark - The 50 K resistor was marked 50 and it took hours to find the problem.
I have a 30 gallon plastic barrel that I hope to use as a variometer form and use 6: PVC for the inner coil.

Yes, 2500 uH is not at all unusual for LowFER tuning. In fact, it frequently takes more. My antenna requires over 3500 uH to resonate.
The rules of thumb for calculating antenna capacitance are not very good, IMO. But I've had very good results from simply measuring antenna capacitance with a Radio Shack multimeter that determines capacitance based upon the time required for charge/discharge cycles. For electrically short antennas, the values of capacitance measured by this electrostatic method agree very closely (within 0.5%) with my AIM-4170 antenna analyzer at actual operating frequency.

I have used the capacitor reading from a fluke meter on a short(antenna length) medium wave transmitting antenna to get a starting point for a loading coil but I never went back and checked the accuracy. It did seem to get me pretty close as I remember.

Sure would love to have an article for The LOWDOWN as well.
We used to alert our readers of the Night of Nights, thanks to the old MRHS e-mail list letting us know who all was participating, long enough before deadline to get something in print. That's useful because a lot of our members don't spend that much time on the Internet. Then it got to where the best we could do is report some of the results afterward from their Web site.
This year, they didn't even post anything about results there, but said to subscribe to the new electronic newsletter...which I did, and one finally arrived in my e-mail today, and is indeed quite nice. But apparently the one talking about this year's Night of Nights was itself already history.
I am putting together a background piece from text at the NPS Web site, together with pictures taken by my former boss when he was there on the AFCCE tour. It sure would be great to have some specifics of this year's event to go along with that, though. ( Hint, hint, Paul. :) )

Wow. I wasn't smart enough to think of that method. And I had an old Rat Shak multimeter with that feature. Instead I used the the pf per foot method. Something like 1.5pf per foot for the mast and 1pf per foot for the tophat 12 gauge stranded wire. That worked and got me in the ball park. Re: New Lowfer Transmiter/Loading Coil

I forgot to add that because of all the research I had done I was shooting for 300pf or more top hat capacitance. That value needed to get a smaller value loading coil. Using the pf per foot method can give you an idea of top hat capacitance before you have committed to hauling it aloft. VK2XV HiFER Grabber Online again...

G'day Mauro,
No idea what it might be - but there have been a few 'world-wide' bursts of signals from time to time on this band. Not surprising I guess because the 13.555 MHz is a bit of a free-for-all for ISM devices (non-communication devices), some of which can be 1kW or so. Actually it is surprising there is not more noise signals than there is. I took the grabber off 13.5MHz here for a week or so because of persistent interference. Hopefully that has gone now - at least for the time being.

Signals on 12 KHz
Posted by Steve on August 09, 2012 at 19:06:38.
Stumbled upon some traffic on approximately 12 KHz, sig level approx S-9...comes in the form of short bursts ( possibly packet type format ? )spaced approximately one second or so apart; bursts seem to be several seconds in duration...number of burst varies; pauses between bursts also vary. Sometimes, during pauses, there are lower level burst signals evident at an S-7 level ( just at my local noise level ). Other times, only the lower sig., level station is evident; the stronger of the two then comes on after a considerable pause.
These signals are not evident, here, during the day nor early evening hours..
Don't know the time when they start or stop transmitting...Have been hearing this apparent traffic between approx 0815 & 1000 UT.
At this point am puzzled since Omega is, apparently, off-the air.

Returning Lowfer
Posted by Jerry Parker on August 22, 2012 at 19:23:23.
Hi everyone.
Some 20 years ago I ran the "OWR" Lowfer Beacon out on 50 acres
near Paso Robles California.
My coil was 60/40 litz on a huge 3 x 4 foot pvc/plywood form with a
6 inch pvc variometer.
When I placed the whole system up on top of over 200 radials made out of
surplus cable tv hardline each over 100 feet long I held a antenna party
out here
with the likes of Mike Medeke, Cliff Buschard, Jim Erickson, Bob Horton and
several others.
OWR was heard all over the western US and I was able to work the fellows up
in
the San Jose/San Fran area as well as Utah, Nevada and Arizona.
Unfortunately the land sold shortly and OWR became a Beacon of the past.
Here I am several years later and I recently purchased 40 acres near
Creston California.
I am in the process of getting reacquainted with the band and toying with
the idea of
putting up another OWR.
If everyone could help me with a list of current Beacons/modes that are up
on the air
I would appreciate it.
I am looking for a complete set of Western updates and any current info on
things.
Thanks ahead of time to everyone for your help.

I have been picking up a lot of very good skip transmissions on the cb band and I was wondering about when the lowfer transmissions start getting some good distance? I have had trouble receiving anything so far other than a local navigational NDB’s. There are a few local stations listed on the lowfer page but I am not sure they are on. Who should I be able to receive in spectrum lab with a down converter at this time in Florence sc or is it too early?

"...I was wondering about when the lowfer transmissions start getting some good distance?"
LowFER DX is a lot like the old saying about gold: it's where you find it.
Take this capture of LowFER EAR by Garry Hess K3SIW on August 1, for instance, over a distance of roughly 350 miles:
It demonstrates that LF propagation exists year-around, especially for signals arriving predominantly by groundwave. While it is true that daytime skywave is more attenuated by the D-layer in summer when the sun is more nearly overhead (and even more if there is x-ray flux from a solar flare), nighttime signal strengths are not as strongly impacted as you might expect. Don't get me wrong; there is a certain amount of genuine seasonal variation, although it also has some surprising traits...it doesn't strictly peak when nights are longest, for instance, but generally in the first half of December, not the second half.
When we speak of a "LowFER season," what we are mainly talking about is when static levels are at their lowest. It's possible to find quiet early mornings even in mid-summer sometimes, but of course, late autumn through late winter offer the most opportunities for QRN-free listening. When you get into that time of year, the best antenna you can manage and plenty of gain will prove useful.
This brings up the question of your downcoverter. Could you describe it to us? In addition to static, LF is a noisy place from manmade sources, too--not just at the target frequency but all around it. If you use an image rejecting downconverter instead of a simpler direct-conversion design, that'd often be helpful in eliminating a lot of noise that might be burying the signal you want to receive.

John,
That circuit will work, but it will be very succeptable to overload. The NE602 is not a good mixer with respect to overload and IMD performance. You will need a very good lowpass filter ahead of your mixer. Otherwise AM broadcast station will likely overload the NE602.
You will also need something to match your antenna to the filter unless you are using an active probe or a loop with a 50 ohm output impedance preamp. The filet needs to be matched to the actual input and output impedance or it will not work well. Usually they are designed for 50 ohms.
Most antennas at LF have very high impedances - above 100K ohms.
John Davis has a very good preamp design for matching an antenna to the receiver. It also has filtering built in.
If you don't get a low pass filter that is properly impedance matched, you are going to be disapointed.
Most all of the noise and hash that you are hearing is probably generated in your house. To get rid of the house generated noize, get the antenna away from the house and use a well shielded feedline. I used two common mode chokes in my feedline. Clifton Labs has the plans for a very good one on the website. It made a remarkable difference in my noise level
I use an active antenna about 300 feet from my house at the edge of a lake. I usually can hear 25 NDBs most any time. Most are within 400 miles but at night in the winter, very long distances are usual and easy to copy.

I've been looking into this myself and have found three options at this time:
SDR-IQ - About $500 new. Supposedly sensitive at VLF/LF and stable enough for QRSS.
Winradio Excalibur Pro - Very pricy at $1600. Starts slowly loosing sensitivity below 200kHz, but should be plenty sensitive for weak signal work at 1750 and 2200 meters. 0.5 ppm frequency stability, so should be plenty stable for QRSS.
Genesis G11 - This is a kit with surface mount components already installed. About $300. It is actually a transceiver, and can be set up to transmit on 137 or 500kHz. I think the receive coverage is 50kHz-2MHz. Don't know a lot about it other than that. The web page needs work as far as making information easy to find.
There is also the Perseus, but I think the manufacturer now condiseres it a "legacy" product and is no longer updating the software.

I did some tuning today to improve the signal radiated. I
would appreciate any reports for OH if there might be a

Thanks,
Tom

Tom, Steve's grabber is at www.qsl.net/vk2xv/. Unfortunately, it is off as of this moment.
Best of luck on your transpacific journey when the grabber returns!
