Back To the Original Question
Jim Henry asked: (Paraphrasing)- "Is it possible to feed audio from Zara to the BUTT Encoder and to the Studio Monitor (the hardware output from the soundcard) BOTH AT THE SAME TIME?"
This is an important question and so far Artisan (DavidC) is the only one of us who included an answer to the question when he said: "I use a utility that came with VAC - Audio Repeater - assign VAC2 as input and my computer's speaker jack as output (which is then routed to the transmitter)."
This DOES WORK and I have spent a lot of time experimenting with the Audio Repeater Tool that comes with the paid version of Virtual Cable.
Yesterday I tried to accomplish the same thing with the free VB-Audio (virtual cable) and was unable to do so, but I became admittedly confused by the accompanying instructions and have yet to comprehend how to manage this software.
Unless I missed it, Admin (MRAM) did not address how he monitors his Zara-BUTT setup, and I hope MRAM returns to the site of this traffic scene to comment further.

Couldn't a radio be the studio monitor?
EDIT-- Nevevermind, your paraphrase threw me off. His actual question was : "So will BUTT, or Shoutcast, or any other application allow you to send your stream to both your transmitter AND the Internet?" Which was answered by David, to use multiple VACs.
But still.. Why not simply use a radio as a studio monitor? Or simply use a splitter at the audio output.

Another Useful Detail In the Complex of Designing a Streaming System
End80 asked: "Why not simply use a radio as a studio monitor?"
Yes!
Here at KDX we use ONLY radio for all the monitoring we do.
KDX does not have ANY hard-wired speaker monitors.
Even audio editing is done at 89.9 MHz using a C.Crane FM2 Transmitter and C.Crane Radio Plus.

How's the food at Sunrise?

The Compellor is fantastic on AM, I'm not sure why someone would advise against it. There are TONS of Part 15 AMs (and full powers too!) that have an aphex compellor in the airchain. The Compellor works best when feeding a processor, which is pretty much what it was built for. It also can be used to protect an STL from overmod.

Compellors and Exciters
We have an Aphex Compellor and Aphex Aural Exciter over in the audio room... it is now like a sunken ship because it was part of our audio/video business but is rarely used anymore.
During the 1990s we duplicated audio cassettes by the thousands and after testing many compressor/limiters I was very super impressed by the two Aphex devices as part of the audio chain for duplication.
The objective in those days was to make the audio cassettes sound as loud and clear and undistorted as possible. The Compellor does a fantastic job of raising the average level very strongly with absolutely no noticeable artifacts as you'd hear on some compressors and the Aural Exciter re-constituted upper-audio harmonics that tend to get lost in some magnetic tape recording while also bringing low frequencies back into time-alignment with a feature called "Big Bottom".
I have never tested the Aphex Compellor with radio transmitters.

Sorry, did I say that, I said it backwards. The Aphex Compellor is good to go, it's the Aphex Dominator of which was advised to me was not ideal for AM. Nevertheless, I observe that the Dominator definitely does boost the signal loudness noticeably without distorting the signal, so it's not I'm disappointed with the Dominator, but I've never compared it to using a processor which is actually made for AM, like a Orban or a CRL unit.
The Sunrise is a breakfast restaurant, though they do offer burgers. It's open from 6am to 2pm everyday. Good food, and good staff, employees tend to continue long term. The restaurant is roomy, comfortable, clean and attractive. It's popular, with good prices.
It's owned by a Chinese woman named Agnes, who also happens to be who I rent this little store front from. I had also rented this same spot back in the early 1990s for about a year or so, during the time of which I had also leased the little diner next door in front of Nickies Lounge.
Incidentally, I assume you're looking on google street view. That huge vinyl canvas purple canopy to the Sunrise restaurant was re-covered about two or three years ago.. If I recall right it cost her about $7,000-$10,000 to have it completely redone.
Well, the hurricane a few months ago had ripped and twisted the entire steel framework off the building, and ripped the canvas at some seams.. She hired someone to come and remove and dispose of the remnants, but I stepped in to confiscate the vinyl canvas, because it was premium quality, and still reasonably new with no fade, and perfectly appropriate to recover all the cushions in my boat, and frame a new canopy for the cockpit, and still have plenty left over!
Of course I still have not been able to get my sailboat off the dry land of the island the hurricane stranded it on, (it's no small task) but eventually it's going to come off of there, so that canvas will go to good use, even though the color is not something I would have chosen, but it's not bad, and the canvas should hold up well for another twenty years. You'd be surprised how expensive marine grade canvas is.
Ok.. back to part 15..

I've heard of a few P15 stations running the Dominator but I think it doesn't allow for asymmetrical modulation. That could be what makes it not optimal for AM use. (I wonder if popping a 222 after it would make it any better?)

I'm not sure. I mean I've never really been clear on the concept of asymmetrical modulation, but yes it is apparent that the 222 does allow for it, though not it's actual purpose, which is to confine frequency within specific limits to conform to requirements of licensed broadcast (hope I described that correctly). Also, even with a 222, isn't it necessary to hook it up to a scope and know how to use it in order to even take advantage of the 222s ability of allowing the positive and negative peaks?
Lastly, and I hesitate to mention this since I noticed someone just offered an 222 for sale at the part15.us forum, but I have heard on numerous occasions through the years that many owners don't particularly like the way the 222s sound, so I quit desiring one years ago.
So when and if I ever do replace my Dominator (which I do like the sound quality of), for something specifically intended for AM, it will probably be something like an Orban or the more reasonably priced CRL units. |

End80, .... ..You mentioned your 5000 is being built in slow motion. Did by any chance did you order it assembled and tested from Pat? I did and ordered mine from him on 12/6. A few days later he emailed me to tell me he had it in stock but had 5 others to assemble ahead of mine.... Jim I had bought my 3000 second hand from a guy name Paul Bock back in 2011. I just searched out our old correspondence and yes in this email he tells me it was built by a guy named Pat: ..I forgot to mention that the SStran was professionally assembled by Pat Ryan from Overtheair3.com in St. Louis, Mo. I had him build the transmitter with the intention of NOT using the external coil and antenna design for Part 15 broadcasting so you'll have to make some minor changes to the circuits if you plan on using it for broadcasting. I think these changes are outlined in the instruction manual that I shipped with the transmitter. If not, they can be found either directly on the SStran webpage or a link from their page to Carl Van Olden who makes the coils and ground systems for the transmitter.
Additionally, I had him set the broadcast frequency at 1700 for the AM band. This I know is easy to change... |

This is why I ordered a 5000 instead of a 3000, the antenna flexibility. BTW Pat's domain is ontheair3.com, not overtheair3.com. End80, .... ..You mentioned your 5000 is being built in slow motion.

The above is just a copy and paste from his email, so I guess he just type the ontheair address wrong.
I didn't realize the 5000 somehow had more antenna flexibility than the 3000.. I do know the 3000 has the option of being used with either a regular wire or a base loaded antenna, it's just a matter of different connections.
