I really don't have a preference,the cbc unit is the only one I have experience with,but I will say this,they are alright for a m,BUT for ssb RF proscessing is the way to go,I know of no kits but most top name ham radios come with it switchable,I've found in my own experience that a fully modulated carrier with no distortion has the most natural sound,but a proscessor may be useful in competition and pile-ups and with an RF amp ohHO!,but be careful you can overheat an amp using one very quickly.Bigbob |

Best speech processor?
For AM- Omnia AM
Reason 1: Large parameter selection can taylor bandwidth and limiting for each of 4 bands to tailor dayparts.
Reason 2: Digital processing power gives high loudness for minimal perceived distortion.
Reason 3: Ramovable flash card can store processor settings and allow easy setup of additional units at other installations.
For FM- Orban Optimod 8400
Reason 1: High end processing is much better than previous units with noticeable reduction of sizzle on highly processed info.
Reason 2: Ability to plud AES/EBU directly into unit and get composite out makes losses in audio chain the last thing on my mind.
Reason 3: The ability in 'advanced' mode to tailor individual nuances that program directors will never understand. |

The original Optimod 8400 has a poor quality op-amp in the front end which causes hum & noise and won't pass proofs...8400B is the precious model to desire! |

Oh yea, Here's what I run:
Mic: Sennheiser e855 Dynamic Microphone
Effects/Procecssing: Alesis MidiVerb 4
Compression: Yamaha GC2020C Limiter/Compressor
EQ: Yamaha GQ1031-C Mono 31-Band 1/3 Octave EQ
My three reasons: Studio quality, what the professionals run on stage, I use it as a Sound Engineer for my side job and know the quality I get, might have to sell it to pay bills since I got laid off. lol
Seriously, all the big gun hams are running professional grade audio processing gear and for a good reason. Just listen the the broadcast quality of the 75 meter band Dawgs!
This is the procecssor of choice among the Big Gun stations: 
Although you might need a PhD to understand how to operate it if you have never seen this type equipment before.
Good Luck!

Sp-1a, is speech compressor, tunable input and tunable output easy to install 29.99 cant beat that with a stick! |

What if you are using a turner +3B like me and the mic already has voice compression, will this clash with a speech processor? |

That compressor looked more like a compandor,besides I don't think I could paint my car with it, |

I`m using with my TS870s Behringer equipment.
B1 microphone, DSP1124p parametric eq and MIC2200 tube preamp. Reasons? Studio quality audio, no problem to tune, I like it.
For my second trx - modified Lincoln I`m using home made preamp with compression and noise gate based on SSM2166 - best for home use with not only CB radios. It gives punch, clarity, compression and noise gate, what is important to cancel background noise. I highly recommend that.
For schematic go to search engine, it is easy to build. |

Just thought of something, now with my echo board taking up space in my Galaxy DX 95T, I can put this device into my rig and use the echo switch to turn it on and off, I already know where the microphone wiring is in this rig too..
Hmmmm...

Mr rf
I would love to hear the audio on that setup.I like the deep basey sound.I run the Md-200 mic and want to someday get a audio equilizer in line.I dont think I'll go as far as you did but thats pretty impressive!
Take care! Gage

Gage,
It's all being in the right place at the right time, and knowing the distributors of the gear. therefore i get big discounts on gear when I want something at home too...Perks!!! I am in the A/V dept of a rather large church and we have spent mega bucks on sound reinforcement, 7 zones of audio, monitor and FOH mix points, click tracks, orchestra, we have even published our music and do studio quality sound tracks from the sanctuary. It's the most impressive sound system I have ever been a part of or seen in medium size churches in my travels.
In fact, most major Christian singing groups and artists have been in our church at one time or another and I have even been blessed with mixing music for them. This has certaintly been the most exciting thing I have ever done with my hobby time! And the blessing is seeing these groups come in and being comfortable enough with our system and staff that they don't even unload their gear, and give their roadies a much needed break.
I know I am very blessed to have had the opportunity to play with such quality gear and see lives changed through the sound of music! |

Gabriel,
Hooking up the gear is very simple. Most all professional audio gear uses either what's called "XLR" or 1/4" phone connections. It's really a plug-n-go technology and requiring only a soldering iron and maybe a matching transformer to hook it up to two-way equipment. I have mine configured in the same order as it appears above in my post...mic to effects, to compressor, etc. If you buy gear consider stereo (two channel) devices. It only cost a little bit more for the stereo version of the mono stuff and you can use it on the home stereo if you ever get tired of it on the radio. There are used equipment sites too. Mail order equipment dealers usually have better prices than locals assuming you don't have any local contacts. These guys are great: http://www.stagesound.com/ and these are a close second: http://www.sweetwater.com/
The only trick to the final hookup is PTT switching. Some radios, especially some CB's require the mic audio to be switched out of line during receive to prevent feedback during receive. And ham gear needs mic audio live to make VOX circuits function. So, attention to mic switching is as tricky as it gets.
Also, some rigs have a mic input impedence of 2K ohms and higher. The professional gear is usually 150 to 600 ohms so ocasionally a matching transformer is neccesary. However, most transformers change the frequency reaponse of the network but not enough to notice it on the air.
Tune-up is a whole different story, everyone has a different way, most all of which ends up with the same similiar results. You can't listen to yourself talk and tune-up very easy unless you have been doing it a very long time. And, there isn't an easy way to do it well without a piece of gear called an RTA (real time analyzer).
Also, tune-up using the least ammount of power, and into a dummy load. That's the nice way to prevent interference to others. One more thing, most radios really roll off the TX audio response around 4 to 6 khz and trying to push the high end only causes unwanted distortion. Also, too much low end audio will stress the components in the TX audio circuits most CB's very quickly. Another note, if the radio's built in modulation limiter ("the clippers") have been removed then you will want to run the compression amp last in the chain of equipment. A last note: common grounding of all equipment is very important, and running all equipment from the same wall socket will all help reduce any hum & noise.
Start off small with the mic you have, an excellent mic, and a 1/3 octive graphic eq and compressor/gate. These two devices are the meat of the processing and will make even an average mic sound like a million bucks.
Oh, one more thing, use the reverbs to enhanse the audio by keeping the timings short but roomy. Not big and hollow...this does nothing for the sound quality, just makes sounds or noise as I call it!
Ok, that's my epistle on this subject. Good luck to anyone who tries this and most of all be nice and have fun with it, don't boast on the air, just enjoy the compliments and keep'm in suspense as to how you do it!!! |

Mr RF, can you record what you sound like on AM so we can hear what your audio must sound like.. Maybe you could put the sound file on the web somewhere, or email me the file and I can put it on the web and give the web address for public listening. I bet it sounds awesome.. |
