Perfect Transmitter

SS Trans EX
Or a SS Trans 3000 with a TH ATU ?
Or perhaps a rangemaster with two slaves for even better coverage.

A Big Fat CBS Compressor to push that signal and perhaps a AM Stereo Rig.
Then we at ALPB sell the radio to listen to our Kick butt AM Stereo broadcasts.

Would the 3000 & ATU be legal? I bet that would be strong though...

I like Breakaway or Stereo Tool for the audio. Perceptually, it cleanly lets me squeeze the signal into a nice 98%-100% pancake. With the TH I have, it is helpful....

What about matching the whole thing with Rangemasters and using that same synch for a CC... (IE: amplify a Rangemaster into a coupler)...

I gotta get me an SSTrans. Don't want to have to build it though... maybe after Christmas.

If you put the antenna at the transmitter with a very short cable, it should be the same as using any other antenna.

The trick is to get the antenna to load right depending on what the SST output is designed to work into.

If it already has a loading coil internally, not so good. I'm sure this has been discussed here somewhere.

But, to separate the SST from the ATU with a long cable, no, the SST with the ATU is not certified as a system as the TH with ATU is.

You can't have PowerSide and C-QUAM on the same carrier. Like I was explaining and answering this point in your other thread, and at my forum, PowerSide is a "lop sided" sideband method which pumps up the upper sideband, and lowers the lower sideband. C-QUAM needs a symmetrical level of BOTH sidebands so that the 90* shifted lobes of the L-R signals are at proper phase AND amplitude in relation to the main L+R envelope.

The result will be the L-R information tilted to one channel in the receiver, while the other one will contain either muffled distortion or an out of phase condition at a lower level.

If you study up on the C-QUAM format, and the PowerSide format, you will then see why the two won't work together.

Leave out the C-QUAM, then your dream transmitter could be a reality. Or leave out the PowerSide, same thing, can become working transmitter. But with both, no way.

BTW..there is a reason why PowerSide has fallen out of favor. I would research that too. Basically it doesn't work too well with the NRSC pyramid curve AND by itself, doesn't work too well with standard AM detectors which looks at the whole envelope and needs the whole envelope..ie both equal lower and upper side bands.

Your transmitter concept would work if receiver manufacturers incorporated detectors that could follow and adjust to the transmitted format. An example of that is some of Sony's receivers made in the 80's that could decode all 4 of the AM stereo formats...ie Kahn-Hazeltine/Harris/Magnavox/Motorola.

Out of those 4, only two were compatible with mono receivers. The Harris V-CPM and Motorola's C-QUAM.

"But, to separate the SST from the ATU with a long cable, no, the SST with the ATU is not certified as a system as the TH with ATU is."

Correct..for 15.219. However he could combine the SSTran and the Talking House ATU with a long coax and operate under 15.209..providing he meets the 24,000/f uV @ 30 meter field strength.

But that mode of operation will produce a weaker field strength than a 15.219 system will. Moral there is to operate the ATU with it's TH transmitter as those have been certified as one unit under the certification number, which you pointed out.

The AMT3000 may work with the TH ATU when the AMT3000 is set up as it must be for the external base loaded antenna. However, coax between the units will not work because it would disturb the L-network scheme for matching the transmitter to the base-loaded antenna. The presence of the extra RF transformer before the tuning coils in the ATU also raises doubt concerning the L-network. The transformer may need to be bypassed.

The AMT5000 would work with the TH ATU with two restrictions. No coax, and the absolute requirement to bypass the ATU RF transformer. However, using the ATU in place of the internal tuning network in the AMT5000 wouldn't make much sense because it would cause greater losses. The ATU uses small ferrite slug tuned coils which are lossier than the iron powder toroid already built into the AMT5000.

All of my transmitters are perfect.

Tonight the programming I heard from my own station was so superb that I got down on the ground and kissed my AMT5000.

It was not like kissing shoes. I have done that, as many men have, but I would say that it was more like kissing Kim Bassinger.

Then of course I rush over to the two AMT3000s to be sure they don't feel ignored and smooch each one.

If I had a Talking House I might simply kiss the cheek.

Carl, I want your BC world to BE perfect...I have a TH I will sell you cheap...

Thank you AM radioman, but I don't think I would be happy with a Talking House. That's why I said I'd only smooch it on the cheek, which is kind of an evasive action.

But if others find success with Talking Houses, that is a very good thing and I encourage it.

The SStran transmitters are so excellent that I am not looking for an improvement by looking elsewhere.

I almost feel guilty about it, because the Rangemaster and Chez Procaster also deserve our support.
