According to the scientific theory of entropy, the universe is drifting apart. All planetary bodies are becoming farther away from each other.
It occurs to me that this same thing is happening in the communications arena, where individuals are ever more empowered to be separately connected to the cloud by way of mp3 players and wi-fi hot spots so that central control is a vanishing monopoly.
As we all drift farther apart from each other there will come a day when we are each alone without a society around us.
At that time we might miss each other.
So while we still have a vaque sense of each other, we should share thoughts while we still can.
TRANSMITTER SECURITY is on my mind.
By transmitter security I mean the safety of the transmitter not only from lightning, but from theft.
As I get closer to building my first outdoor AM transmitter installations, I am beginning to feel insecure about putting valued AMT5000 transmitters out in the open where somebody could come along and steal them.
People steal potted plants, lawn equipment, yard furniture and even ornamental rocks.
A transmitter at the base of a pole near the ground would be asking to be taken.
No wonder people put transmitters up high on rooftops, or run long transmission lines from indoor safety.
One way we can distrust strangers, the other way the FCC.
The Part 15ers who want to use their FM permission become very befuddled about how to meet the rules, since they require a field intensity measurement so microscopic that one member says it can't be detected because it'll be "in the noise."
Maybe I'm getting confused with the 15.209 rule for AM, but my uncertainty kind of makes the point I'm making...
Plain people are allowed to operate transmitters under the FCC rules without having a diploma from radio technical school, but the FCC requires compliance infinitely beyond the comprehension of even the most popular man.
Given the dilema posed by the FCC rules for FM, I believe there's only one thing to do.
We should build the FM station of our dreams and wait until the FCC provides the service of coming along and making a field intensity reading. If they tell us to close shop we must remember to thank them for letting us know what we do not know on our own.

Would such befuddlement be minimized or maybe eliminated by researching and buying an FM transmitter that had been provably FCC-certified to meet §15.239, and by installing/operating it without increasing its output power setting as shipped, and/or modifying the antenna supplied with it?
The suggestion posed by Rich(F) begins from the realm of the reasonable. But in the physical world of what nominally passes as reality there come unexpected imponderables.
The so-called certified FM transmitters come with instructions included.
I own three brands of them and one of them includes a detailed mathematical formula for adding a resonant antenna, another suggests adding lengths of antenna wire to "improve" results, and a third includes frequencies not allowed for Part 15 operation, i.e., 87.5, 87.7, 87.9 MHz. CERTIFIED!!
When none-of-the-above results in usable use of these things, one tends to wonder if there might be a slight improvement possible.
If they can't be made to work, what's the point of 15.239?
Broadcast on FM radio for TWO FEET without wire!

What is the definition of "usable?"
Probably (when unmodified), such unlicensed FM transmitters with FCC Part 15 certification work within the limits defined by FCC §15.239.
Understood, those limits may be less than desired by some operators of such systems.
But in every case, doesn't the ultimate responsibility for FCC compliance under Part 15 lie with the buyer/installer/operator of unlicensed AM/FM setups, rather than the manufacturer(s) of its component parts?
I'm actually quite surprised that Part 15'ers are even allowed to use FM, given its popularity and the money involved.
I personally would be willing to live with NO FM Part 15, but the rules relaxed for Part 15 AM. It might revive the AM band with creative programming, while reducing potential interference on FM (you know anyone on the FM band is a pirate).
If you'd absorbed my original point your question would never arise.
"But in every case, doesn't the responsibility for FCC compliance under Part 15 lie with the buyer/installer/operator of unlicensed AM/FM setups." - so said Rich(F).
How can the responsibility be exercised by the user when the field strength reading required for compliance is utterly beyond the user to confirm?
None the less I enjoy your adherence to absolute uniformity with the rule.
Shall we click our heels and extend the right hand toward the homeland?

A major technical point was missed in the above quote.
Buyers/installers/operators of systems with FCC §15.239 certification have no need to measure/prove the fields it produces 3 meters away from its antenna, assuming that such an unmodified system actually complied with FCC §15.239 when it was received and installed, in the first place.
That is the purpose of using hardware with Part 15 certification.

IMO that comment is inflammatory and unprofessional, and posted by its author without due consideration (hopefully).
How dismissive you are of what's said.
Always back to the rules as they apply without thought.
There is no professionality from which to depart.
The inflammation precedes me and comes from the persistent accuser flapping the rules in the face.
Goodnight!

I thought about this subject, and posted its realities -- which you have not disproven.
Clearly you don't like those realities.
But does that change them?
Are you talking about your realities or mine?

There is only ONE reality.
See http://www.merriam-webster.com/dictionary/reality (among other similar definitions commonly learned in grade school).
I thought my Talking House would be idiot proof safe but simply plugging in the power supply which provides the transmitter a grounding point makes it non-compliant per previous discussions ad nauseam.
Not off topic-I'm just sharring my thoughts.
Every living person has a conception of reality.
Even the philosophers concede that each of us has his/her individual perception.
If there was one reality, there would only be one person in the world to experience it.
