528Hz was the frequency given as "the frequency of love."

Too late, for many Japanese, sorry.

Silly, probably in any case, but entertainment has its place.

PhilB is the well-respected designer and distributor of the SSTRAN AMT3000 transmitter kit

Wonderful....Obamah is the president....and.......

Perhaps that point could use another point. At one time even the mighty have to begin with tiny steps and had to go beyond the first...second..thrid and so on....even when at the top...one needs to look around and find out there is yet another step to go even further....that is if one is so inclined to do that...or remain where they are because its comfy.

All well in good.....for those who like where they are...does not apply to all. As long as that can be remembered..that there is no such thing as a one blanket fits all, especially when it comes to knowledge and ability, then everyone can reach a higher achievement.

Just a matter of prospective for one self. As to those who are at their comfy zone....its best to let others find their own higher goals without putting a thumb over their heads simply due to some success which becomes irrelevant when thrown around.

Cheers.

Ken puts things in perspective. That's
a whole big story by itself.

The other thing - and I don't want to
sound like a broken record - but the
Part 15 US board is a big part of my
life. I takes me away from the difficult
things that we all face in our lives. For
a little while every day I can get on here
and sort of dream about what I would
have always wanted - which was my
own radio station. When I was s lot younger,
I always pictured having a 1000 watt day/
250 watt night station in some little building.
It would be on 1490, or something like that.
And there would be a tower in the backyard. This
board, and experimenting with this stuff
sort of fulfills that dream.

I do tend to think outside of the box, but
that is because of my limitations. I could
not build the 3 meter antenna and loading
coil that Phil designed. I can't drive, so I
can't get the parts (well, there's more to
it than that.) Right now I wouldn't
be able to see well enough to assemble
the 3 meter antenna anyway. When I had
more vision, I built
my SS-Tran. It took me about 3 months to
do it. When I powered it up, I was lucky because
it worked.

When I decided to try to change the SS-Tran
from a yardcaster to something larger, I didn't
know what to do. I knew I wouldn't be able
to make the published 3 meter coil/antenna design.
So I opened a path in the
RF coil section of the transmitter, where the
little tiny fixed RF coils are. I put in a much
much larger coil, with many taps, and a sliding
ferrite(???) core to tune it. It doesn't fit in the SS-Tran
enclosure, so I had to put it on the outside of
the transmitter. But it is part of the transmitter.

No pun intended, but this time I guess I was
thinking outside of the box!

Anyway, the SS-Tran is one of my prized
possessions. I obtained a second unit.
It is not assembled, but I have a friend who
will do it for me.

The other thing that was mentioned by Neil,
and I think some other people, was this:

If you check out what the Longwave Part 15
people are doing (160 to 190 kHz) it is really
interesting. There is A LOT going on down in
that part of the spectrum.

Thanks for listening guys. I appreciate it.

Bruce, MICRO1690/1700

An air-core loading coil has nearby electric and magnetic fields external (as well as internal) to the coil. If the external fields pass through conductors near the coil, the loading coil Q is reduced, causing greater coil loss than if the coil were remote from conducting objects.

A loading coil near the base of an antenna would suffer reduced Q from electric and magnetic fields from the coil passing through dirt, as well as the ground shield. If the antenna is center-loaded, the coil would be more remote from the dirt and ground shield, resulting in better coil Q.

Incidentally, loading coils wound on ferrite or powdered-iron troroids (or pot-cores, etc.) would have reduced external fields, but the toroid material itself is lossy, at least to some extent, and often results in reduced coil Q compared to an air-core coil with the same inductance.

I admire MICRO1700 for his persistence in pursuing an electronics career and hobby despite his low vision. He explained in a previous post that he was born with this condition; but even so, he became an electronics specialist. This is quite an achievement!

Can you elaborate? I haven't seen any forum contributions from the basement folk ... where are they?

Despite the protestations, I found little respect in the response to PhilB's post. And it's too bad, because it certainly diminished the credibility of the points the poster was attempting to raise, at least for me.

Both are right, in my opinion. And both are also wrong. At the core of the 2 posts is not technical issues, but procedural ones. How to best solve a problem.

There are really only two approaches, each at opposite ends of the spectrum. PhilB is describing a Solution Builder, interested primarily in getting an end solution, something up and running (and hopefully, somewhat effectively). At the other end, RFBurns is describing the Tinkerer, who is interested in solving problems, without necessarily getting anything physically running.

Of course, each and every individual uses both approaches to varying degrees, but everyone falls into either one camp or the other. I'm by nature primarily a Solution Builder, so I understand where PhilB is coming from. Solve the most important issues! Stop fiddling around with things that likely won't work, they're just a waste of time. I'm more interesting in playing around with the resulting radio station, than solving the myriad of technical issues to squeeze out just a bit more range. Radio station running at 60% vs no radio station - for me, there's really no issue, I'll take the former every time and not look back.

On the other hand, some of the most brilliant people I've ever known have been primarily tinkerers. Rarely actually completing anything, they would attack problems that interested them, and when they got a solution that they were satisified with, they moved on. In many case, they provided the basis for what I did to complete the work and apply it to the end solution.

Different approaches. Different mindsets. Both worthy of respect.

THANK YOU!!!

So I was long winded in my post. For good reason. I found the post I was replying to to be more of protecting marketing interests than the interest of helping the experimenter seeking those unusual ways of doing things.

That's just how the post came across to me so I replied to it based on that.

The post does have a point...going the quickest route to going on air. All well in good. But the majority here are already on the air or are close to going on air..so obviously there are the "traditional" sticks already in place.

After being on air at that point...when someone sits there in their studio wondering "what if I did this"...and seeks out advice in forums such as this asking that question, it is only fair to respond in kind and help them out with their idea..not start quoting regulations and "honored tradition" worn out statements found on forums A to Z. That is not exactly providing much enthusiasm for the hobby, its more like popping the balloon of enthusiasm to the person who wants to expand their knowledge.

Perhaps that was not the intent of the poster. The original poster has yet to comment since the start of this thread...which I find unusual but that is just my take on it. So I will not make assumption or assertion..only stand my ground in what I replied with..and still do.

RFB

"only stand my ground in what I replied with..and still do."

For me it was more about the rough tone of delivery than content. This constitutes the end of my comments on this thread.

The problem is that practically nobody has the instruments needed for making quantitative measurements. A 3dB change in signal level represents twice the power level, but it is very difficult to detect by ear when using an ordinary radio receiver as the measurement instrument.

It's the same problem in ham radio. Hams have been experimenting with various antenna configurations for about a century, but definite conclusions are rare.

Experimentation is a good thing because it increases expertise. Just keep in mind that it is really difficult to prove anything by performing experiments that do not involve the use of professional test instruments.

The opening contribution by PhilB has been seeping into my ongoing thoughts about finally mounting an outdoor rig, and now a seed has sprouted.

The outdoor installation will be 100% ultimate, based on the letter of what PhilB described. For me it will serve as a laboratory standard and remain intact permanently.

I also happen to enjoy the novel experimentation that presumes known science to suffer from the shadow of unknown science (things waiting to be discovered), and will do experimental setups, but the beauty is that it will be possible to compare the trial setup to the lab standard setup.

Perhaps the trickiest part about comparing two setups is trying to get them as physically alike as possible, i.e., same height, same clearance from objects, etc., but that part of the design question is also interesting as a project.

Another inspiration came today in a radio conversation between two research psychologists who discussed the new discovery that at the quantum level, it is possible for a particle to be in two places at the same time; it is possible for one particle to influence a second particle instantly regardless of distance, ignoring the speed of light; light waves under observation convert to particles, the point being that the observer of quantum space changes it by observing.

What does this have to do with radio transmission? I don't have the slightest idea.

Soft and cuddly rarely applies these days when points need to be made. Ever been to New York or Los Angeles in heavy traffic? Try it sometime...think I was rough....HA!

I was incredibly nice compared to the colorful metaphor exchanges that takes place there. But if what I said ripped the rice paper and smashed the egg shells that lines the floor here...well I'm terribly sorry I speak my mind.

Be nice if the poster did the same thing and not depend on the minions to speak for him after purposely posting crap that anyone with a 1st grade education can clearly see is a post intended to cause the dust to fly. 2 days and counting and not a peep. Don't any of you find that as being a bit of a tilted picture on the wall?

In any case...experimentation is the key to discovery and ideas are the key to invention. Without them, we would still be in the stone age. Face it...progress happens when thought and creativity are allowed to function without a leash. It has been that way and will always be that way. Want to remain in the past...go to a 3rd world country or find a time machine and go back to the time when it was all comfy cozy. Good luck with that!

In the meantime...time moves this other direction..forward..as does discoveries and progress. It cannot be stopped by anyone. It only stops when you stop yourselves, or let someone else lead you to the dead end.

As to the quantum particles....light is a part of the electromagnetic spectrum..as is radio. It's been years since the discovery of moving quantum particles from one point to another was possible. It is called Quantum Teleportation, some neat videos about it here >>>>

Michio Kaku is one of the leading researchers on this subject.

Yes..indeed...progress friends. And this technology stemmed from thinking OUTSIDE the box and ignoring the stale pale tradition nonsense.

Remain in the past if you like...just do not stand in anyone's way who wishes to move into the future...be it with quantum mechanics..or new antennas.

Cheers.

Carl, it has to do with everything I'm sure. But when the time comes that we can comprehend and harness it, I doubt there be any desire or need to be broadcasting on the AM or FM bands!

I don't find that strange RFB. When attacked, a person generally has two options; either to react with a like force attack, or to deter from the act of force and avoid the onslaught all together.
I like you RFB, but was definitely shocked when I read your initial response to Phils post - it took me by surprise and was quite unwarranted and out of place.
It gave me the impression that you two must have had some kind of ongoing feud going on for you to have lashed out like that. It caused me re-read Phils post to see what I had missed.. and there was nothing there to explain the attack.
It seemed to just come from out of the blue.

I think Phil's attitude may be that an unwarranted comment doesn't warrant a response.

I have no idea who Phil is, or have ever spoken with the guy, or anything else for that matter since being a member of this forum. Other than what I knew through a graphic website link on the left column over there.

After owning/administrating/moderating forums over the last 15 years, some of them far more popular than any of these radio forums, with memberships exceeding 500,000, I can tell you this guy's agenda is that of something every forum board has to deal with. And it is not to help any of you out there with your antenna ideas or anything else.

It's called trolling and board baiting.

So I called him out. Funny...but like a roach lurking in the dark when the light shines brightly upon them..they scatter and hide and not come back out till the light goes out. Well the light has not gone out with this yet...and where is the roach?

That was an analogy, I'm not calling him a roach in case some of you need it ABC 123 clarified there. :/

The post could have been put in the on-going thread about antennas and top hats..but it got posted in a new thread so it would appear at the top of the new topic list like a bright neon sign, first line is "everyone looking for holy grail antennas" as if like that is such a bad thing, post once and then vanish. Why? THINK ABOUT THAT FOR 1 SECOND!!!

A typical tactic all too common of a baiting board troller with no more intent to but to cause division amongst the gathered at the round table discussion where wonderful ideas are being exchanged.

Sad...just frigging sad.

Well like Rich, I'm done with this particular nonsense and this particular worthless thread. I got better things to do than to feed this false king's ego. You all might want to find something else better to do as well and quit feeding the king who will gladly bite your head off if you think outside the box.

Cheers

For some time, I have been experimenting with top-loading coils for Part 15 AM. They work about the same as capacitive hats. The only method for doing the design is cut-and-try. The NEC antenna simulation program will work for base-loading and center-loading coils, but not for a top-loading coil. This is because an inductor in an NEC simulation is a lumped-constant element with zero dimensions, and therefore with no coil capacitance. The self-capacitance of a top-loading coil is an important part of its design. The inductance is considerably higher than for either center-loading or base-loading.

Because the coil is heavy, guy ropes are necessary for a pemanent installation, but I haven't used any for my experiments. It would be nice to have a field strength meter for this work, but what I do for testing is take a walk from the antenna while it is transmitting a 1 kHz tone to see how far away I can hear the signal on a portable radio. This gives me a relative reading for various antenna configurations.
