[station21]

any body trying out motormouth mauls cobra 29 and modulator set up. is it worth the cash or what?:confused::confused:

[Mr. 557]

I really don't know anyone who has one. Never heard any feedback. I know that its a bit expensive though!

[10 Gauge]

Doesn't the Mauldulator just basically convert a cheap ass radio in to a transmitter, nothing more, leaving it up to the user what kind of audio pre-processing they want to use?

[sky hawk in the big horn]

A little more than that. Work has to be done to the radio just to allow the wider band spectrum through it from what i have been told. Then you have to use your rack gear or pc with a processing program.

After i am done with christmas, or when the tech that does this that i know has a spot open on his bench. I will be trying this also.

What good is having wide band transmit audio, if everyone out there is running a narrow 7.8khz front end? Sounds sort of like a waste, unless you are only going to use it locally with your friends who have had their receive modified.

[10 Gauge]

Hrmmmm. Wonder if I could get this to work with my condensor mic and my behringer fx mixer. That would be fun to toy with. I need a free sample. ;)

[Mr. 557]

Apparently from what I am gathering here, they use a Cobra 29 and convert it to a wide spectrum transmitter. Won't see a bunch of watts, but get a lot of bottom end wide sound.

Company Description About The Mauldulator

The Mauldulator does many things.

It allows the user to have a blank canvas for audio frequency response, and the ability to create 200% positive peak modulation and maintain 100% negative peak modulation. Coupled with the users own Audio processing, and limiting gear, the signature sound that the user creates is entirely up to the user with NO limitations on behalf of the transmitter. Just as Picasso is able to create a masterpiece on a piece of canvas, the very same peiece of canvas in placed in front of a three year old may proove to look quite different.

The Mauldulator comes with a new modified Cobra 29 LTD. Of which the receive circuit has been opened up to allow the user to experience HI FI audio, while maintaining the stock IF filter to keep the adjacent channel rejection to spec.

Only the RF Final and Driver stages are used in transmit, and the Mauldulator Board takes over every aspect of the modulation and carrier control.

Due to CB wives tales and other ways that Power, referred to as Watts gets goofed up, our Mauldulator is rated differently
We specify that the radio will dead key 3/4 Watt in to 50 Ohms. We specify that it can make positive peak modulation of 200%.
Peak watts are a relatively useless term unless those Watts are measured in to 50 Ohms, AND the carrier is modulated by a true Sine Wave.

The Mauldulator can produce just a Sine Wave, but it really shines on Asymmetrical Modulation. This is what broadcasters do.
CB wive tales speak of " Swing " It is beyond the scope of this description to discuss this. Suffice it to say that True Asymmetrical Modulation is LOUDER than the same looking signal on a scope created withe Swing Mod. This is due to the actual power in the Sidebands. Study Amplitude Modulation.

The user will have to LINEARLY amplify this signal to their desired or legal operating level.
Notice that I did not say use a linear amplifier. THERE IS A DIFFERENCE.

In addition to the above, The Mauldulator comes with Remotomaul. Remotomaul allows the user to set the radio up, and remotely control PTT and send and receive HI FI audio from anywhere on the Internet. You can be on vacation 1000 miles away, and sound like you are at your station. In the future, this Remotomaul will include a remote S-meter, as well as remote channel and squelch control for a adtional cost.

Finally, the Mauldulator has the audio connections to make great recordings, or " Watergates " and has a local receiver audio input that the user can pipe the audio from a local receiver into to get their audio on the recording off air instead of off the mixer or preamp. This input only works in Local mode ( when the user would be recording ) not in Remote mode when using the station from another location. The recorded audio can then be played back over the air if the
Remote/Local switch is momentarily placed in Remote mode.

This is an overview of what the Mauldulator has to offer.

If you haven't noticed a lot more people stepping out with these mods done. If enough people step out that can RX and TX wide band then we will hear the difference.

Even the Wright bros was thought of as idiots at first. Now there is not a day that you can look into the sky and see their results. And maybe one day it will be the same on the band.

[295]

I haven't heard anyone with the muddy audio (when listening to a wide band signal on a narrow front end) on the band around here. I've heard the SSB cousin of this on ham (ESSB), but they still keep the bandwidth sensible around 3.6 -4.0 khz. If you go too wide the effective transmit energy starts dropping off.

I am not saying anyone is an idiot, but this "new technology" is not new at all, but is something that has been around for years. Tune across the AM dial and you will hear it in use everyday. It is good for broadcast, but not too good for communication. When you open up the front end on the recieve end, you also let in all those narrow band signals, so use of the regular CB channels would be limited. Imagine trying to listening to six or seven channels at once, your wide band signal would get clobbered on the recieve end if the band is open. Sounds like a fun novelty, but I doubt if we will ever see any wide spread use of this.

By no means i am not saying "NEW" i have listen to am broadcast. But to our hobby "CB" it is newer to us. Not all do not like it. Same as not all do not like c class amps.

As with me i do not like hams. I even let my call expire. KC5HKV. One of the first groups of nocodes that did not have nothing more than tech class. And if you wanted hf then you had to pass the code. But the elders would let you know that we was nothing more than a glorified cber. Man i just wish i could see all those hams now that there is no codes on their precious hf band.... :lol::lol::lol:

But as with all things in cb. It may come, it may go. But i will still be here on the 11 meter band. I have seen so many people come into the hobby with gusto and leave out like the july winds in Texas (Dead still and quiet)

And one thing i have always seen. What one person likes on the band is another persons annoyance. Such as roger beeps, echo, noise toys... the list goes on. Not one radio , amp , or antenna can ever be mutually agreed upon as being the best for our hobby because there are so many taste as to what is good and bad for our hobby.

[MoJo]

That's why these radios are optimized for the bowl and it is recommended you use an AB1 biased amp with them.

All that code/no code garbage died off long ago, no one even cares anymore, it's only a few bitter old farts who even bring it up these days. I never got involved in any of that crap, I had better things to focus my energy upon, and I have more sense than to listen to a bunch of old fools crying about the FCC changing the testing requirements, it is what it is, you earned your ticket, and that is good enough for me. Too bad you let it lapse because a bunch of old fools turned you off to the hobby.

Nevertheless, I too have seen many come and go in both realms over the years, and I've seen tons of gimmicks come and go too. One of the problems with 11 meters is there are so many snake oil salesmen lurking around trying to pull money out of unsuspecting people's pockets for the current must have flavor of the month.

It's not a matter of like or dislike, just trying to understand the reasoning behind this, where is the advantage or what is someone gaining? If there is nothing to gain, seems like a waste to me. It reminds me of those hams who invent some new digital mode that no one can copy, that is a waste too.:yesnod:

The biggest of the snake oils. RadioHACKTIVE and stargun beams.:lol::lol:

As far as gains. To have someone that is RX in wideband to watergate your TX. Then when you pass on to the other side. Your family will be able to hear you from the watergates that you have stored from your friends or like me. I consider my fellow dxer's as family.

[HiDef]

Real hi-fi transmit audio done right still sounds better than a lot of other radios on many stock receivers. You don't need a 20 kc wide filter to hear the increased articulation.

[CCWaters]

Bottom-Line........


Nothing new, even on 11 meters, 25+ years ago people were playing with the principles on CB. Only thing new is introduction of computers into the mix, and the latency issues suck, going to be a bit yet before software is up to affordable real-time processing.

Mauldulator might be a fine piece of gear but until he gets the price down substantially, and has worked out installs for more popular radios (think its just 148GTL and 29 right now) Its not going to be very popular. Also no reason in the world this has to be restricted to any one frequency or band.

Installing isn't that hard, but to be successful they are going to need road maps for mainstream radio.

[HiDef]

The latency seems to drive a lot of people nuts but it really isn't that bad to listen to when you get used to it.

My opinion is it's well worth the major advance in reduced transient compression using the "look ahead" gain reduction loop.

[mikehammer]

What Motormouth is doing is absolutely not new... HOWEVER, it is new to 11meters.

The reason he uses the 29, and 148 is because he is only using the radio to generate a dead carrier. Why do it to a more fancy radio. Also, He is asymmetrically modulating the carrier. It is a big difference. He also completes the receive mod that he has devised.

Asymmetrical modulation is not a top gun mod. The carrier does not grow with the modulation.

His 29 with the mauldulator is a bargain compared to a connex 4300-400 or other expensive radio.

I do realize that most people dont want it... Cool.

Agreed, my issues with latency depend greatly where I'm using it, Slow keys of a lazy round table its not an issue....

Any how I doubt it will be to much longer and the latency issues should be reduced even further...

What kind of delay are you experiencing? I don't use a PeeCee for audio but I do use a stand alone unit which uses A to D and D back to A. IIRC it's delay is less than 300 milliseconds. Fast keying is no problem.

[mikehammer]

Many of the latency issues are caused by the breakaway software. You can avoid them with pro tools or rackmount compressor/limiter/eq gear.

[Mr. 557]

Does anyone have a watergate of this Mauldulator? I would be interested in hearing the before and after results.

[CCWaters]

Exactly, however 100% PC processed audio is probably the wave of the future, and lets you get buy with minimal hardware investment. Problem is it currently still runs about .5 second latency. Nothing big, but enough to make live monitoring difficult, and use for communications Annoying. I've tried the newer low latency ASIO version of a specific software, and it is better... Still a ways to go though.

Is a few around of MMM, but I've yet to hear one that is impressive, everything I've heard contains some nasty AC, he even comments about it... Just don't understand how a supposed Audio Guru cannot keep the AC out of his gates:confused:

[mikehammer]

yes there are watergates available on page two of wwwmotormouthmaul.com Click the picture of the Mauldulator on page one.

Also, he is featured on Prime's song The Hammer hits hard. Many of those gates were recorded on his equipment. He then edited them and sent them to Prime for inclusion in the song.

There will always be haters. Thats what I love about CB. Citizens Band, means you dont always like what you get but, you get the will of the people.

BTW the AC hum is in one particular gate. and its in his studio. That gate was recorded to help 626 improve his audio. The AC hum is not a by-product of the Mauldulator circuit.

[CCWaters]

The AC hum is not a by-product of the Mauldulator circuit.


I've heard it on more then one, and when did I say it was caused by the Mauldulator?

[mikehammer]

where in my post did I say anything about you? I merely said BTW... It was for informational purposes only. You are entitled to be non-impressed. In fact thats what makes America great, a sense of entitlement. LOL

Mr. No pity in Virginia has at times also run a Mauldulator. As well as Rickety Bones in Arizona and a few others.

MMM is in fact a Broadcast Engineer.

[CCWaters]

and your point is? MMM isn't even the brains behind the Mauldulator...

[mikehammer]

ROFL.

[CCWaters]

Not from MMM's keyboard..........



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.


AND


"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."


As seen on another forum.....

He may be the one marketing the Mauldulator, and perhaps even packaging it with "remotomaul" or whatever its called, but then those are not what is at the heart of the "Mauldulator" Again, this stuff is old news modernized....

On that note, I'd like to give one a try...

[HiDef]

Broadcast engineers are scary.

This is recorded by grasshopper of ms. He is on 28 and you can hear it about half way into the gate.....

Good gate grasshopper i hope you do not mind i posted this.

[Mr. 557]

Might be my computer, but can't get it to work.

[sky hawk in the big horn]

Might be my computer, but can't get it to work.

Still working on the site to work with vista. XP works fine with it. I had to down load quicktime on to my setup on 7. I had to also load it on to my Vista sytem.

Also you will have to turnoff pop up blocker for it to start playing. There is no sponsors on the site for popups. The popup is the gate starting to play in quicktime.

If you still can not get it to play. You can click download link and it will download it on to your pc then you can open it up.

[ala skipshooter]

Just wish i could get a cross the yard.:d
