Eschew obfuscation.
Consult with Arthur Schopenhauer and we find that the negative is exactly what is true about the world, and the positive the exception.
By such enlightened reasoning we can say that part 15 is a very negative subject, yet we all hope for those positive exceptions which might give us relief from the home arrest imposed by the federal government.
To Mr. Janze:
I so much respect how you've shown trust in the membership in being free to speak for themselves and I also feel very comfortable with the membership who are very self-regulating and have never been flagged by homeland security for dangerous speech. The webmasters have very seldom called "time out", but even then, it's done with delicacy.
Any website that tolerates me must be great.
"...accurately describing the technical functioning of "Part 15" systems..."
First, hardly accurate. You've made many statements since you've resurfaced that, when called upon, you've had to clarify (such as your outlandish - Part 15 signals are not useful beyond a mile).
Second, your ATTEMPTS at technical accuracy are one thing, but your additional comments are hardly positive. Such as your continuing insinuation that most Part 15 operators do not attempt to adhere to "THE RULES". Even your statement in the above post - from what I've seen and read, the rules ARE the basis for Part 15 broadcasting (otherwise, we could all become pirates), and certainly they are very important. But not the be all and end all.
There is so much more to this hobby, or whatever you want to call it. And the rules are open to interpretation. What is considered compliant yesterday may not be considered compliant today. Hardly technical. Or science. Just politics.
So your continuing harping on legality makes me wonder - just what is it you're trying to do here - REALLY - since you don't appear to want to stick just to the facts, ma'am, in spite of your protestations?
i say one thing and one thing only.
if we were not trying to strive to be legal wouldn't we just say eff it push the tx to it's maximum power into huge antenna's and not bother buying expensive test gear such as SA's, FIM's, Scopes, DMM's, etc or be here asking questions on how to push the limits and serve our communities while still being legal?
i say no. we would not be here if we were blatant bootleggers and did not care about being legal we would be on forums such as the pcs electronics pirate radio forum ,etc talking about how to get away with running high power tx's on fm while avoiding the fcc, etc.
certain individuals arguments don't hold water about us being illegal.

I don't write that anyone here is operating illegally, and truthfully I could not -- because I would not know if they were, or not.
I post technically accurate information about how Part 15 systems operate.
However readers view their operations with respect to that information is left for them to decide, privately.
It's up to the inspecting agent if a setup is compliant or not, none of us here has that decisive power, regardless of what is assumed to be, it is not until validated either by actually seeing the setup, or measuring it.
As it has been noted, and now more apparent than ever, laws are written vaguely and left for interpretation that is also open to swing in either direction for the situation at the moment.
This all means that there is no absolute rule or law that is 100 percent clear or precise. That in of itself is a conundrum and a major conflict.
Is it any wonder why DC is so mucked up?
And its all lawyers up there.
Go figure!
RFB
DC is so mucked up?
No say it inset so LOL!
But I will say this, Nothing has really changed over all in this county other that we have become fat lazy TV Watching yahoo's .
It's up to us to fix all that is wrong with our country , If you leave it up to the stupid people who killed our economy then you will get what they want for you.
Take our Part 15 network , That is us doing something about an issue we don't like.
That is all we need to do , Is deal with the issues our selves .
In other words it is up to you and me to fix DC.
As the infamous document begins with the all familiar 3 words "WE THE PEOPLE", it means the people do have the end say and are the only ones capable of changing things.
Though big brother wants you to believe that complying to their crooked laws is mandatory, it is not. It is US..the people that GRANT them authority. That means they work FOR US.
Now until the population recognizes that and stands up together in a huge mass, nothing is going to change and the powers that should not be will continue to do what they are currently doing.
And anyone, I mean anyone show me and the entire world what they are doing to better things.
Anyone?
RFB
There is a small misunderstanding about the expression WE THE PEOPLE.
It really refers to a small race of Wee People believed to exist in Irish mythology living somewhere in the green forest, which of course is brittle brown in the drought.....
But the thugs do work for us. In principle.
We are not responsible when you consider what is going on in our Country.
What every single American needs to do is get off the couch and shut the moron box off and pay attention to what these people are doing IN DC.
Then when they do things that are against the US Constitution they should be removed from office period .
Example , The FCC has an issue with my antenna because some radio maggot hates the fact that we are stealing the ratings number from them ??
Then we need to change the laws and make better sense for our Radio service.
In other words we are in charge if we do the right things.
The Government does not own our airwaves , We do .
So we must take care of it . And if we vote simpletons in who make changes to their benefit then we need to remove them.
That is our Job.
Have a swell day and remember we are in charge .
problems is the system is rigged so all we have is simpletons now. look at our choices. obama and romney. what kind of choice is that? a Marxist and the other Bush II who will continue and expand upon bushes failed policies.
"I post technically accurate information about how Part 15 systems operate."
Might I ask is this technically accurate information based on NEC simulations or actual systems you have set up and measured and then compared to the computer simulations, then put 2 and 2 together to develop the conclusions?
Going over other sites, there apparently is the question if you have ever actually set up a Part 15 MW system.
From my own hands on experience, both with computer simulations and actual systems, the two rarely ever get along very well.

From my own hands on experience, both with computer simulations and actual systems, the two rarely ever get along very well.
As with all computer programs, accuracy of the results depends on the accuracy of the input data (the model). But M-o-M software (NEC) is used to design the directional arrays of licensed AM broadcast stations, which must (and do) meet their pattern requirements required by the FCC, and do produce the field intensities calculated by NEC.
Calculating this performance requires Maxwell's equations, which prior to computers had to be applied by other means. But the underlying science has not changed. The software just makes it easier to use those equations, and to provide graphics of the results.
It is true that I do not have a Part 15 AM setup, but this isn't a prerequisite for setting up an accurate NEC model. That just requires knowledge of antenna theory/practice, and of the proper use of the software. My 40+ years of engineering experience in the broadcast industry also is helpful.
In another thread I have opened what will be a long running research on the results of various designs of indoor AM & FM antennas for part 15 application.
If the NEC simulations are able to describe indoor systems it could be very helpful to making the results technically expressible.
In my point of view this should take into account the degree of attenuation introduced as signals escape the indoor environment and radiate outside the building. It is in the outdoor domain where the FCC has jurisdiction to measure the signals in line with the part 15 rules.
NEC will calculate the radiation pattern of an antenna, but it is not the best tool to determine the effect of the passage of radiation from indoors to outdoors.
Such effects vary considerably depending on the construction of the building, the operating frequency, and other factors.
I have a Tecsun PL310 receiver, which displays the strength of the received signal in "dBµ." When I tune it to a local station on 1530 kHz, it reads the same maximum value no matter where I am in my house as when I am outside the house.
On a local FM station, the radio reads about 3 dB lower inside the house than outside, in general, but there are some places on the first floor of the house where it reads 5-6 dB lower.
My house is a typical ranch style, brick veneer structure. Houses with aluminum siding, stucco over a metal grid, buildings with steel beams etc all behave differently. In some cases they can make radio reception inside them almost impossible.
