Booty why not ask these questions at the place it originated from and get the answers directly from the people involved.
thats a very fair question Camo . ive only see this on CB forums . i do enjoy CB forums but ive learned that sometimes folks are caught up in the advertising or personal connection to a product or person producing it , and just accept something as true . and some just have bad ideas . ive also found when something doesnt make sense to me or i develop a intrest in something that i can come here and get answers that i feel during the course of the post that common sense and truth will rise to the top . and ive learned that NOT ALL folks selling and/or building equipment focused on CB'ers can be trustet for truthful or technically correct answers . i certianly dont understand all the answers i get here all the time . but they give me a basis in facts that as time goes buy i SOMETIMES gradually understand more and i use google and such to search topics and sometimes individual technical words or terms . yea...........im a nerd . but i find it greatly entertaining and add to my joy of this hobby .
think of it as having a diagnoses from a doc-in-a-box and then getting a second opinion from a specialist .
ive said it befor and ill say it again..........this is my go to place when i really want to know whats going on .

Booty you hit on the way to get "broadcast" audio. Get a Yaesu (just an example) or similar radio where the mic plugs into the rear and it keys when you start speaking. That way you can run your mic through all kinds of rack gear, delays, eq's etc. and have as a result a full range audio. Have you heard any of fortymobiles videogates ? I wouldn't buy into this maul whatever snake oil.
"Everytime I've heard MMM in dx he's always had his lips clipped and it only gets worse with his bass reverbatronoplastisizer software. imho he sounds like shit. Bob85 will try and dispute my opinion."
"Don't be swayed".
he's 59 when the band is open here and is trounced regularly. the audio IMHO is noticably muddy, missing too much midrange and no hi-end at all. what i would term low-end syllabic distortion is readily discernable. i'm with you.

all 40's videogates are totally processed after the radio, not impressed there either.

that may be but since we were discussing tx audio I mentioned the fact that his mic is put through processors prior to the input stage of his transmitter giving him a fuller audio

key word being "broadcast"

...after the radio I guess you mean rx which is 180 degrees from my point

the reality is that cobra 148 gtl dx you have when aligned properly probably has better tx audio than 75% of far more expensive yaesu's.and all the rack gear in the world ain't gonna change that.

I heard that a lot of times jazzsinger (about the 148GTL-DX) but since acquiring my amateur status I've been using the AR and the 2950 more. currently eyeing a FT-101
I wanted to respond to the responses I saw about the Mauldulator. I will try to respond in chronological order. First off, I will plead guilty in advance to some bias because I am the one that designed the asymmetry circuit used in this device. I was there the first night of the proof of concept, and the proof was dramatic. I am also the person that came up with the receive mod on the 148 that several people have performed and are happy with
Next, I would like to point out that the mauldulator allows you to have a blank palette, meaning that whatever you put in is what you get out. Whatever MMM puts in to it, it is what he wants to sound like. He is in the broadcast business and routinely tunes the processing at commercial stations and has a reputation. I agree that I don't always like the sound, and I don't like reverb, but he likes it. The first night we had the circuit going, we had absolutely no low or high pass filtering. We could literally go down to 5 Hz and we did go all the way up to 30 KHz input signal. When we put in a 30 KHz signal, we saw a dead carrier 3 channels above and below the channel we were on. I hope that established the bonafides of the fidelity possible with this thing. We had to intentionally roll off the high end and low end, but they are well beyond the bandpass of all the radios listening
My first direct response is to this comment --> "asymmetrical modulation is what an "NPC" mod produces." This comment is technically true, but has little to do with the mauldulator. Negative peak clipping does produce an asymmetrical result, but the clipping that occurred also introduced unnecessary distortion. Furthermore, whatever asymmetry is produced still has the limit of radios internal circuitry for whatever positive peaks can be reached. Finally, you are still limited to the fidelity of the radios circuitry even with the distorted asymmetry.
The mauldulator suffers from none of the problems. None of the internal audio circuitry is involved at all, and the RF stage is directly modulated. While it is true that asymmetrically modulating the envelope is technically distortion in itself, at least you don't need to have multiple stage of distortion with the mauldulator. The perception of loudness is definitely there, and broadcast stations routinely use asymmetry with 125% positive peaks. They would not be doing it if it did not have a benefit. The only downside I have experienced so far is that in some radios, the rapid envelope growth is perceived by the noise blanker to be noise and it causes a problem. If this is happening, the signal is strong enough that the noise blanker is not required. There is a youtube video showing the envelope growth from a customer at
"ive got far better and more important things to spend $800 bucks on" was one comment I have seen. That is a personal preference and not really a reflection of the quality of the mauldulator. "seems for $800 a ham radio converted to 11 meters would be a much better and cost effective option , not to mention much more frequency and mode options" Again, this comment is not speaking to the quality of the mauldulator, but the priorities of the writer. This product was not meant for you. Hell, I designed this thing and I don't even use it on CB, but that is because I can't get into the lingo. It has nothing to do with the technical merits. I challenge you to come up with a ham radio that can beat this system on AM. Of course that challenge is meaningless in a discussion that is filled with subjective terms. That is one of the downfalls of discussions like this because so many things are in the ears of the beholder.
"all you need to do an NPC-RC mod is a resistor and a diode. LOL". You can do that, but again, this has nothing to do with the mauldulator. It's like saying a skateboard is like a Lotus because they both have four wheels.
"Everytime I've heard MMM in dx he's always had his lips clipped and it only gets worse with his bass reverbatronoplastisizer software. imho he sounds like shit." I like this answer actually. He called it his opinion. I don't always like MMMs audio either, but HE DOES! I did not buy my radio for your enjoyment, I bought it for my enjoyment. I did not paint my car for the opinion of others, I chose the color I liked. Of course others can have an opinion, but the point is you can make the mauldulator sound like whatever you want. Also, you mention every time you hear MMM. I wonder how many of you have ever been heard by him.
I need to comment on the "plastiszer" comment also. I have my share of tube equipment, but I am slowly phasing it out. Part of the reason is because of this mauldulator and how it works. Yes, I will be using it on the amateur bands where I am comfortable. This whole project came about because people were saying that you could not make a "plastic radio" sound good. That theory has been invalidated. Again, this is a blank palette, even more than a high level plate modulated tube rig that has the limitations of the transformer to deal with.
"he's 59 when the band is open here and is trounced regularly". Sounds like you are discussing signal strength and not audio quality. That being said, he has got to get more attention than anybody else that is using a lowly 5/8 ground plane 1 foot off the roof.
"Booty you hit on the way to get "broadcast" audio. Get a Yaesu (just an example) or similar radio where the mic plugs into the rear and it keys when you start speaking. That way you can run your mic through all kinds of rack gear, delays, eq's etc. and have as a result a full range audio". You bring that stock ham radio over here, and if it can even match, not beat, the mauldulator, I'll put a $100 bill in your hand.
Broadcast stations (music) have different requirements that non-broadcast stations (voice). I've yet to see a non-broadcast station benefit from using broadcast quality audio, unless they are sending something that has a wider frequency range than the human voice. (Don't get caught at it, it can get expensive.)
That wider than normal voice frequency range always ends up with a wider transmitted signal. That's probably the biggest problem with doing that, you take up more than normal frequency space with no practical benefit. Sort of like driving an 18 foot wide car. Might mean lots of conveniences on the inside, but a real PITA for those you happen to meet on a typical street. I also wanna see you find a parking space for that thing!
