Re: 630m Crossbanders Tonight
I heard you last night on 630m, 559, attempting to get info from K6TOP, who I didn't hear (nor sure what freq he was on). I heard sporadic frequencies being transmitted, but not sure from whom or to whom ...3566 & 7066. I was listening on my TS-870 using my HB 20m triangular yagi. I was listening on 630m only...didn't try any of the other frequencies for crossbanding swling.

I live In hasard Ky and would be willing to travel up to 125 miles from home to meet or deliver this radio to avoid shipping. i would also ship but it is a heavy radio around 80 lbs and it would cost alot to ship.

I own a Montronics Model 220-1 VLF receiver. Never used it before but it powers ok and would like to see it in operation. I have no manual. It fits in a 19" rack. The unit has a rear antenna BNC connector along with a 100Kc input and two output BNC connections with Hi/Lo settings on the front panel. There is also a multi-turn pot for Gain setting. There is also a 1/4" phone jack but no label. No xtal input or VFO so I am going to guess this may be a downconverter but unknown of what IF frequency.
Has anyone worked with one of these before? Looking for guidance. Email me back, thanks!

Introduce myself and a question.
Posted by Walter M. Meek on November 08, 2014 at 15:33:14.
Hello all, I would like to introduce myself. My name is Mike, amateur radio callsign N8OOU. I live in Southern Illinois. I have had an interest in the lowfer bands since the 70's but never actively pursued that interest until retiring in the 2000's. Since that time I have improved my receiving station and have had moderate success in receiving dx stations in the 30 to 500 Khz range.
I have been an occasional reader of this forum, and an occasional contributor on a Lowfer maillist. Earlier this year Warren K2ORS put out an offer for someone to take ownership of the Bill Ashlock Wm beacon. I replied and was offered the opportunity to put the beacon back on the air.
I now have the equipment in my possession, and have started putting the station together by getting an antenna hung in the sky. I plan to have the beacon operational for this “2014/15 lowfer season”, and establish a web site as a memorial to Mr. Ashlock who was one of the early lowfer pioneers.
My first question to this group is may I operate the beacon on the 185.3 frequency that Mr. Ashlock previously used. The beacon will remain a part 15 operation with the original QRSS Wm graphic.
At this time I have no idea for how well my antenna will perform and what my coverage area will be. I hope to become a good player in this hobby, in the manor that Mr. Ashlock established.
Have a nice day. DE N8OOU Mike Meek 73

Sorry to see no one has had an answer for you yet. Whether it implements filters narrow enough to be useful in interference rejection is an unknown because they don't tell you up front, so I'm afraid no one but an actual user of the software could tell you. It seems to be oriented more toward VHF and UHF hardware. It's also allegedly written to use the Microsoft .NET Framework, which is not the most efficient use of computing power, IMO.
Personally, I distrust any software package that doesn't give me its specs and installation requirements ahead of time...and which doesn't even let you download, inspect the "readme" file or user manual, or virus scan the files prior to installation! The "Download" button basically only gives you a DOS batch file and an executable called httpget that then goes out across the Web and gathers files onto your machine, bypassing all the usual Microsoft installation procedures and safety checks--such as they are--thereby potentially opening you up to unintended malware as well. I'd recommend caution.

Thank you for the reply.
The base reason for using the sdrsharp and dongle is that it's cheap. The dongle and software covers VHF/UHF, covering 24mhz to 1700 mhz. The software is free and the dongle costs about $10.
There is an upconverter (the ham it up)that upconverts 0.1 MHz to 60 MHz signals to 125mhz to 185 mhz. It's a little more expensive(about $50).
Think I'll play with it for LF. Let you know what I find out!

Wm Beacon testing
Posted by Mike Meek on November 16, 2014 at 16:32:29.
Hello all, I am progressing with making the Wm beacon operational again from my home qth. The beacon is operating on a temporary, small loop antenna. The antenna is installed in a less that ideal location but convenient to access. At this phase I am trying different things, to learn about operating this equipment. That includes different size loops, support structure, loop material, and the like. These tests are being performed during the daytime and the beacon operation will be up and down. I will leave it on overnight if the antenna is in working shape.
On the chance that a signal is being radiated past my county lines it would be found between 185.3002 and 185.3007. It is a graphic Wm sent in QRSS30. If you see something in this range there is a small possibility it could be my signal.
Thanks for reading this. 73 N8OOU Mike

Hi all, Re: Wm Beacon testing
My beacon MLS @ 186.204 was working well until the first big snow storm hit my area. Like last year, I had some cap hat damage due to heavy snow. I had to take it off line till this weekend when the temperature will raise high enough where I can make repairs and retune the antenna. I monitor my field strength and it dropped way down due to the damage. This is the third time it's happened due to the harsh weather conditions over the last couple of seasons. I'm considering trying a loop antenna next year because I can design it to be a lot stronger. I'm getting to old to be out in bad weather. Ha Ha.... As soon as it's back on I'll let everyone know.

The weather warmed up a little today and I had a chance to repair and retune my antenna. Everything went well but then I found that the beacon transmitter suffered some damaged.

If I wind around a cylindrical body of non-conducting material, for example a wooden broom-handle, a insulated wire of quater wave-length, for example 40 metres long wire,for a 160 metres-band antenna, would I get so a well-working compact LF-/MF-transmission antenna? Re: Would this be a good MF-/LF-transmission antenna?
I know helical antennas are used for transceivers working in VHF and I know for electrical enlengthening a loading coil is required. But would it not be possible to extend the coil so, that it is as well antenna as loading coil?
Posted by John Davis on November 25, 2014 at 19:23:03.
In reply to Would this be a good MF-/LF-transmission antenna? posted by Hermann on November 25, 2014
Short answer: the merit of such an antenna depends on how low a frequency you are trying to transmit, and what practical and regulatory limitations exist on its size. Helical antennas have been used with some success at HF and upper MF frequencies by amateur radio operators. It is a misimpression to think that they or any other loading coil will work to lengthen the antenna electrically, however. The main purpose is to achieve resonance, with impedance matching sometimes as a secondary goal.
In some cases, elevating part of the inductance may promote a better impedance match and help reduce power loss due to ground system resistance. However, this is a trade-off that becomes harder to realize at longer wavelengths. The factors which contribute to the antenna's own impedance, the loading coil's transformation effect, resistive loss in the coil winding, ground system loss, and the ability to lengthen the physical structure in proportion to wavelength, no longer mathematically scale in the same way. What works well at VHF is harder to replicate at HF, and what works at HF becomes even harder to do efficiently at LF.
In cases where the physical length of the support is a very small fraction of a wavelength (as it will be at LF) the effective height of the antenna is still one-half the physical length, just as with a conventional short antenna. This can be improved with a capacitive top hat, just as with a typical base loaded vertical. Without at least some top loading, the current distribution in the coil tapers to zero at the top almost as linearly as it does in a conventional base-loaded short antenna; thus, there is little improvement in signal for all that work. Further, top loading is advisable anyway to minimize corona discharge, which is quite capable of turning a helical antenna into a self-destroying Tesla coil with only a few watts of applied RF.
Those issues are not so problematic at VHF, where the typical helical whip--even though physically small--is still a somewhat larger fraction of a wavelength.
In practice, I recall hearing of hams who use helical antennas with some success at 160 meters. The ARRL Handbook, in fact, once contained some guidance on construction thereof, and I think the ARRL Antenna Book probably still does have an article on the subject.
Helicals have also been tried by experimenters in the license-free LF and MF bands here in the States, sometimes with acceptable results and sometimes not, but the bigger problem nowadays is one of regulatory interpretation. Thanks to certain so-called microbroadcasters stretching the Part 15 Rules to the breaking point in recent years, the FCC has issued opinions to the effect that the total length of wire used in constructing the antenna counts toward the limit stated in the Rules. Similar language has actually been formalized in the wording of Industry Canada's RS-210 Rules.
Most experimenters under Part 15 may not be aware of this shift in attitude because they haven't drawn regulatory attention to themselves yet, but our understanding of what complies with the rules has gotten a little more complicated lately. If a loading coil is functionally part of the transmitter tank circuit...as it is in most experimenters' installations...it is arguably a discrete component. But if the coil basically is the antenna, then someone using such a system under Part 15 on highly shaky ground. Even a center mounted loading coil is of debatable legitimacy for license-free compliance these days. And an antenna consisting of a single piece of conductive material, such as a metal sheet or large diameter metal pipe, is now supposed to be measured on the diagonal for compliance purposes. That might seem needlessly picky, but it just goes to show that someone blatantly bending the rules for their own benefit can have consequences on everyone else, eventually.

Sorry. Sometimes there's a little lag in online updates during deadline week for the printed publication, in order to make sure it's as accurate as it can be, since the MS Word document is itself the reference database. The online versions of the lists get temporarily updated from time to time throughout the month (the Message Board serving as a way of getting out word in the interim), and then the beacon lists are totally regenerated again once the print list is in fixed form. That will occur today in time for most folks' holiday listening enjoyment. :)

I have swapped out the loop for a Vertical Flattop antenna. That has made an improvement in the near field signal strength. I have also weather proofed the outside equipment, so I can leave the beacon up during most rain/snow events. I will still need to take it off the air during severe lightning.
I am continuing to test and try improvements to the system. That will normally occur during the daytime, with occasional short outages. I hope to always have it operational overnight.

No other beacons were either audible or visible in the lower half of the band...not even MTI or PBJ...and only FRC (K6FRC) was audible in the upper end. It even shows up somewhat in the Argo NDB mode capture below, although all the characters were audible by ear most cycles.

LowFERs in SE Kansas Saturday Night
Posted by John Davis on November 30, 2014 at 08:17:05.
Tuned in 1750 meters a little after 6 PM CST / 2400 UTC and immediately began getting a solid trace from SIW, plus an unexpected early enhancement on SJ's signal. The latter only lasted for a single ID cycle, but it returned roughly every 40 minutes during the evening. Around 0130 UTC, I saw my first unmistakable squiggles from WM. Early in the evening, QRN was so negligible that everything was below S1 on the meter, but by the last capture of the evening, below, noise picked up to a median level of S3, with excursions between S1 and S5. As a result, I didn't get much more out of SJ (note the final sorta-clear "J" at upper left). It also looked as if I might be about to get traces of TAG until the noise increased around 0440 UTC, but interestingly, the path to Illinois recovered quickly, so I resumed getting good traces from both SIW and WM anyway.
