HiFer RIX Moved, New QTH
Rob Steiger, N9RIX has moved HiFer RIX from his fence in Paxton, IL south to Champaign, IL. It now resides on top of a 21 story apartment building. RIX is on 13.561 and is Solar powered. Antenna is around 220 above average terrain and is hoped this elevation will provide an excellent takeoff angle. We hope to have photos posted soon.

Posted by Rev. Robert P. Chrysafis on January 01, 2010 at 14:33:29.
anyone ever think of building an AM longwave transmitter using class e output
and coupling that to the 50 ft radiator with a tapped toroid output?
basically a rangemaster for long wave.
seems to me with am we could have 3 frequencies in am mode.
165, 175, and 185 khz.
we could have a 600 ohm balanced input.
we could even make them in ssb, cw, and digital modes.
seems something like this over a 50 foot radial system would perform great.
there are lots of possibilities with this type of system.
Re: 1750m band am tx idea
maybe some of the math geniuses here can chime in on what kind of antenna system
bandwidth and performance to expect.

Robert,
I'm not sure there's anything new in what you describe. Class D and Class E PA's are pretty much standard for Part 15 work in the 160-190 kHz band. AM can certainly be used on a local basis, but don't expect reception outside of a few miles at most. Of course, SSB and some digital modes would best be done through a linear PA, though complicated EER techniques would still permit Class D or E.
Be advised that a 0.009 wavelength vertical antenna is a pretty inefficient radiator, and that the long distance reports you see in Lowfer work these days are generally done with very slow data rate digital techniques, not AM. Ground systems are usually as you describe, with radials out to the height of the antenna. Toroidal loading coils are not suitable, due to the high voltage even with 1 watt of power. Fairly large open-core coils are the norm.
Can you explain what you are trying to do? Performance depends heavily on local losses due to trees and buildings, so no simple answers are possible. But if you gave some idea of your intent, we could point you in the right direction.

looking for alternatives to the increasing ground lead enforcement being seen on the AM BCB part 15 stations.
looking to maybe use Lowfer as an stl for a multi site am bcb system or maybe as a local broadcast to the neighborhood in which i would hand out fixed tuned lf rx's with the stations logo on them to people who would like to listen to my station.
keith hamilton is thinking that a change to the wording of p15.219(b) is coming which will cut the legal range of p15am down to that of a mr. microphone.
those of us who purchased $1k certified am tx's are about to be made worth about 1000 cents.

I don't know who Keith Hamilton is or what basis he has for saying that, but I wouldn't be surprised. The "free radio" and so-called LPAM crowd (both manufacturers and operators) have been breaking the spirit and stretching the letter of the rules for a very long time with bogus, overly-generous antenna "interpretations." Those of us who have spent years trying to encourage common sense compliance among amateur experimenters have long been concerned about the possibility of a regulatory backlash because of that, thanks very much.
I wish there were a way to cover small communities with a legal BCB radio service from just one or two transmitters, because my own little town could use such a service, but that's just not how the rules are set up!
For what it's worth, LowFER KLFB did cover a neighborhood with reasonable signal strength using a carefully constructed antenna (including a large, air core loading coil such as the other John mentioned) in an environment relatively free of local loss factors. As he found, though, efficient antennas have relatively narrow audio bandwidth, and vice-versa. It's very difficult to squeeze 5kHz audio through one, even tolerating significant rolloff of the highs. The arrangement worked OK at first for his oldies music format, but I think interest in retro-sounding audio waned; plus, the heavy static that accompanies LF in many areas of the country also discourages regular listening.

http://www.am1000ragemaster.com
a couple others recently hit the market also.
i am hoping competition will drastically bring prices down.
the others are the chez radio procaster and the radio systems i a.m.
i got my rangemaster for $500.00 used. but i think considering what is actually in these things that the prices are pretty steep just to have a certified transmitter.
especially now that the fcc has decided to interpret the "ground lead" issue in an unfavorable way.
i think the way to go will be ground mounting range masters at the edges of a large property and syncing them in a array like the big boys.
some guy in villas wsjl am 1700 ran a cluster on the same tower and got nailed under the class b compliance. they told him to space them apart.
of course you just never get the full story when this stuff crops up so it is impossible to interpret the rules because each agent interprets things there own way.
another thing i was looking at is running cquam in carrier current mode on the low end of the am band using neutral loading.
i am not expecting to cover an entire city from a single, site just a small subdivision.
if i get say 1/2 mile daytime coverage i would be happy.
i have access to am fim for measuring carrier current leakage.
i have heard about just 5 watts into the neutrals on the low end of the band giving excellent results.
i have even considered streaming via a commercial wisp grade access point under part 15.247 and giving out wifi radios.
they can be picked up at hamfests for next to nothing.
i have had lots of ideas kicking around in my head.
i was directed here by someone when i brought up long wave as a possibility. guess you guys are the experts according to the person who referred me.

Robert: *** There are no NPRM's on the FCC database regarding changes to the Part-15 rules on the ground lead issue you mentioned. I did a quick search, and nothing showed up. Field Agents are not at their own personal liberty to " Interpret " the rules as they see fit in the field. The real deal is the fact that if a Field Agent shows up for other than an impromptu inspection, they've already got the goods on you. If you intend to operate a legal Part-15 A.M. station; be pleased with the 1/4th mile coverage area you'll have. The best option you have if you desire Aural radio is to file for a LPFM, otherwise Internet streaming might be a more viable solution. Conclusion; the time to be concerned about an FCC ruling is only when they issue a NPRM.

oh ok. more of mr. hamilton's blower smoke up our rears.
he has become famous for this on other part 15 forums.
i forgot they need to file a nprm for even changing a single word.
the deal was is they were suppose to (according to hamilton) change the word "lead" to "system" in 15.219(b)
and while agents are not suppose to interpret anything they do.
and boston, philly, and west coast field offices have rep's for interpreting the rules to get the part 15 off the air when pressured by local licensed stations.
as opposed to other field offices have interpreted the rules in favor of the part 15.
but like i said earlier. we never get the full story from anyone when there is an enforcement action.

Sounds like a very expensive solution with a few possible drawbacks. How much "syncing" do you have in mind? Unless the carriers are not only on the exact same frequency, but also in the correct phase relationship with each other (which will also depend on the spacing of the transmitters), then the received signals will not add in phase at the destination.
It is not a trivial matter to achieve this result unless there is a physical connection between the transmitters. But if there is some type of wiring connecting them in this manner, then the composite conglomeration is deemed one single system by the FCC, which must in total comply with the limitations of Part 15! (That is, if there are four final amplifiers, the total DC input power to all of them combined must not exceed 100 mW, etc.) This is probably where they guy operating the big cluster on the same frequency ran afoul of the rules.
i am not expecting to cover an entire city from a single, site just a small subdivision.
if i get say 1/2 mile daytime coverage i would be happy.
That is a realistic coverage area for a longwave Part 15 AM station, although as I mentioned before, usable audio bandwidth will be severely limited. Anyone capable of assembling a kit could try the one from North Country Radio, which includes AM mode in its specs.
i have access to am fim for measuring carrier current leakage.
i have heard about just 5 watts into the neutrals on the low end of the band giving excellent results.
Probably so, but there's one tiny problem. It's not legal.
At first glance, it may look like 15.207(b)(1) exempts carrier current systems from conducted signal limits, but that's not the only rule which applies, as you'll see in 15.207(b)(3). One of those specified rules is Section 15.221, which divides carrier current systems into two categories: those using leaky coaxial cable, which apparently could be operated by anyone willing to demonstrate compliance with the radiated limit; and educational institutions using powerlines to conduct signals on campus. It's not legal for anyone, institutional or not, to use powerlines for carrier current off campus. You'd need to be able to run leaky coax through or around your intended coverage area.
And if you aren't in either of those categories, you're stuck with the 1000 uV conducted limit of 15.207 and the radiated limits of 15.209, which aren't really adequate to the task.
i have even considered streaming via a commercial wisp grade access point under part 15.247 and giving out wifi radios.
they can be picked up at hamfests for next to nothing.
That's an intriguing idea. I wish I were more familiar with that hardware.
If nothing else, it might provide you with a high quality STL to a group of individual AM transmitters.

this option is also scalable. it is a trivial matter to setup a mesh network using 5.8ghz (802.11a) as a backbone and traditional 2.4 ghz (802.11b/g/n) on the ap side.
each of the so called "nodes" could be self contained and solar powered.
you are allowed up to 1 watt and a 6dbi omni in p2mp mode although typical tpo is 300mW or less.
getting a node up high will also efficiently cover a lot of real estate per a node.
you would basically stream over a wide area semi private license free wireless intranet.
there are numerous online vendors for carrier grade wifi stuff, as well as a host of municipal wifi, and commercial wisps going bust and flooding the market with quality used gear for cheap.
i have thought of melding the two technologies part 15 am and wifi.
or even placing part 15 certified fm tx's at each mesh node with a self contained stream decoder.
certified part 15 transmitters can be had for 10 bucks. makes you wonder why the certified am tx's cost 600.00 or more. Re: 1750m band am tx idea

ok ;)
i can use a "Wireless" short range video sender and use the video channel for the carrier sync and the audio channel for well the audio.
as a side bar: rangemasters were supposedly type accepted with the syncing feature under part 15.219. but again according to hamilton. his explanation for the wsjl bust was under composite rules, but not because they were connected via wireline, but because they were mounted too close to one another.
but surprise, surprise. no one including the fcc can seem to produce the testing data for the rangemaster so that we can see exactly under what conditions it was certified.
all we have is the certificate stating it was certified under part 15c. Re: 1750m band am tx idea

That would pretty thoroughly destroy the ability to have any ground connection at all. As is, there is no limitation on what is in the ground, only the length of lead going to it--which, I notice, the Rangemaster website weasels around by saying to stick that toroid coil into the ground lead so it's not part of the antenna system.
Well, the FCC makes no such distinction in the rules. Ground connection is ground connection, whether you use it to conduct RF or lightning or microscopic green space aliens. It's also a little disingenous of them to claim the choke makes it not an RF ground anyway, considering that they give lots of advice on burying the radials for maximum effect in increasing range! The truth is, that toroid is only going to act as a supplement to the antenna loading coil.
Basically, the real secret of their self-styled "incredible range" is to put a 102" antenna on top of a transmitter on a 35 foot or longer pole with a correspondingly long ground connection. That's 15 meters of radiator, not 3, so I imagine they aren't too happy with the enforcement crackdown on lead length. Not hard at all to get a couple miles range with a tenth of a watt if you pay only lip service to the antenna limitation.

i hope they indeed do leave the wording in 15.219(b) alone.
the only thing that bothers me about ground mounting a $800.00 transmitter is someone coming along and taking it.
then there is the apartment dweller who does not have access to dirt ground.
i have lived in garden apartments where i had to stick everything in an attic due to a no antenna policy.
fortunately in nj landlords can only regulate what is outside the apartment, not what is in an attic or your 4 walls.
but these are only two of the many scenarios one can think of.
then don't even get me started about city dwellers and this theoretically could apply to long wave experimenters as well.

Hi Rick, Re: "PBO' on for a few more days
I got a copy on PBO but not fully disernable, I have a screen shot, (finally got it working) Sunday ...nothing copied Saturday. turned on spectran Sat 10 to 11:30 local and Sunday in the afternoon arnd 2 to 4 pm local. I'll try again 10 to 11 am local this week. what I copied was washed out but the time was correct for the characters.

Hi Lloyd Longwave Broadcasting Station in Spain - Fake?
Thanks for looking! My loop is facing east/west so Im suprised that you copied as much as you did.Im going to try a different coupling method this weekend and check my antenna current.I notice I draw more current at different parts of the day now with the snow on the ground.
Thanks again

According to http://en.wikipedia.org/wiki/Longwave, there is a 300 metres tall radio mast at Logroņo, Spain, which is used for a longwave broadcasting station on 207 kHz. As I know, there is and was never a longwave broadcasting station in Spain although there are some frequiencies coordinated for Spain. Does this transmitter really exist or is this a fake?

"Fake" is probably too strong a word. More likely, it's a serious misunderstanding by the writer of that article.
The only other place on the Internet that I have found any reference to such a station is also on Wikipedia, in the article about Logroņo itself, which only states that there "may be" a longwave station on 207 there carrying Radio 5, the all-news service.
Certainly, there have been no listener reports of such a station in our loggings column in The LOWDOWN, or in any of the online DX sources I've consulted. At the RNE radio site, only mediumwave AM, FM, and VHF Digital Audio Broadcasting stations are listed anywhere in all of Spain, let alone in the La Rioja region. (http://www.rtve.es/rne/emisoras/frec-rne.htm)
If you'll notice, the Wikipedia longwave article states that the antenna is directional. This would require multiple towers at HF, MF or LF. The only tall tower site near Logroņo that I find through Google shows a single mast on the ESA satellite view. This is most likely the tower hosting the various RNE FM and 204.64 MHz DAB antennas.
Now, considering that VHF radio services can very easily be directional from a single tower, it is possible that someone mistook the DAB frequency in MHz for a longwave frequency in kHz and assumed that a tower of that height would necessarily mean LWBC. That's just a guess about the reason for the misinformation. But whatever the reason, it's pretty clear that there is not really a longwave broadcast station at Logroņo.

Do you mean the mast at 42°26'34"N 2°30'43"W ? It is a mast used for mediumwave broadcasting. But there is surely no 300 metres tall mast at Logroņo!

I did not take note of the geographical coordinates, and there was no way to tell the exact height from that one view. The main point is, although it is the tallest tower I could find in the area associated with RNE, it is clearly NOT part of a directional array for longwave broadcasting; nor does there appear to be any other antenna site in the area which could be used for such.

i believe it is the schematic of a rather popular part 15 certified tx. and yes, the wcbo/ka2vem tx was measured at 1200mW input to final.
i think they are over rated to offer some level of protection for the finals.
if you go over about 300mW you lose asymmetrical capability.
so i believe it was intended for 100mW. Re: High Efficiency MedFer Transmitter Schematic

Solving PC noise in my receiver
Posted by Andy - XR on January 26, 2010 at 20:34:28.
Hi everyone: Just in the hope that this information may be helpful to someone out there going thru the same problem I have for months. I have had horrible noise in my receiver from the PC connected to it. I tried line isolators, line transformers, external filtering, and absolutely nothing worked. Many operators kept telling me that it was my power supply, But it was virtually new. However, it was the noise maker. At the reccomendation of a couple of guys. I was told to " Beef Up " the input filtering in the supply. One operator told me of some SMPS that didn't have any input filtering in them at all !! Well, to my surprise, when I opened my supply case, I found out that mine was one of them. "PBO" back on the air
No input filtering at all, just empty spaces on the circuit board where the filtering components should have been. I had an old power supply that had the filtering parts, and put them in my PC power supply. When I did; the PC noise almost disappeared. It was on a different frequency, and dropped down 20dB.
If you, or someone you know is having problems similar to mine; before you spend the money on a new supply that very well could be the same way; open up the one you have and see if it is filtered. You may save some money in the long run. *** 73 all *** Andy - KU4XR - Beacon " XR " , Friendsville, TN.

Hi Sal. Yes, I just was able to copy EH, about 13557 KHz, about 3/4-3/4-9, with QSB, today(30 Jan. 2010), starting after 2000 UT. No one else heard, but broad band noise is S 2-3. I have heard the sweeping noise and thought it was just local, but then listened 200 mi. out in the Gulf and it's just as strong there. As if the splatter from the SW Bcst on 13070 isn't bad enough. At least it's off on Saturdays. EdWSlidell,LA

How about going qrss 30 or 60 and giving some of us back east a chance to copy?
Let us know how you are getting out.

Hi Paul
I have considered using qrss30. As a matter of fact I am trying to figure out how to program my memory keyer to send 2 messages. First message 5 wpm and second "JAM" ID at qrss30. Thanks for the input.

MP and CV copied overnight with good signals. Also one other signal just above MP but not enough for copy.

The large mast is 94 meters tall which puts in the MW range.
You can measure the heights of masts using Google Earth and the NOAA Solar Position Calculator. Most imagery on GE has a date stamp and you can measure the length and bearing of the shadow. If the antenna is over fairly level ground (most are), you can put the coordinates into the NOAA SPC and adjust the time until the sun azimuth is the reciprocal of the shadow bearing. Then read off the solar elevation. A little trigonometry gives you the mast height.
I've tried this with know masts and it works very well.

New beacon IO on the air
Posted by craig on January 31, 2010 at 23:02:42.
I am setting up a new beacon located in Garrett county - in far-western Maryland. It's on approximately 185.321 although I have not calibrated it yet. I made a first crack at a loading coil but need to tweak it a bit, so can't say if I'm getting out or not.
It id's as IO at approx 10wpm and QRSS10 although the dits are a bit short right now.
It will be on the air all week. If anyone hears it, let me know. Also - if anyone knows of any grabbers that are up and running on 185.3 point me to them as it may give me some way to see if I'm getting any signal out.
