FINE TUNE CB SHOP FOR REAL?

[rabbiporkchop]

RPC, this is a email i sent heil about his mics on the cb. His end quote i hope will come to pass so we could use them on the cb.
Hi Tony
DOn’t have any thoughts on this. Hand microphones are always pretty terrible. The other situation is the the CB transmitters do not have good audio to star with. Wish I had better news.
I am working on an accessory that will allow the use of our balanced professional microphones to be used on the equipment…. Stay tuned
BOB HEIL

It's all about the tune. the pr 781 and the pr 40 work great on my radios and sound awful on almost everyone else's unless you bypass the whole audio chain altogether or Mark had his hand in the radio in which case the Heil would work just fine just like you heard in that video from Mustang 131.
I guess another way of putting it is if you are unable to plug a Heil PR 781 directly into your black box export radio and have it sound phenomenal then it might be time to find a better radio technician because my Anytone at-6666 sounds awesome with the Heil pr40 or 781 plugged directly into it. if you listen to the audio clip again you'll notice a spot where Mark is talking about having the Heil PR 781 but that he's not actually using it and at that point in the recording he's actually using a ranger SRA 198 microphone one of the cheapest microphones out there and it sounds almost as good as the PR 781.

Cheers, Im going to run my 2970n4 at less than half power ( unmodified ) when I get replacement this week. My goal is reliability and stability, maybe I got the wrong radio for that but I feel he can help bring out the best in it. After a lot of research on here and other forums which I am not a member of, I read and learned that its best to have the radio "out of the box" looked at, since more often than not some of the settings from factory are not optimal, and with optimal I am not just talking modulation or power.

I just wired a Heil Sound Gold Elite microphone to plug directly into a Ranger RCI 2970N4 radio. I used the CC-1-K4 adapter cable and had to change the pinout connections. Also using a 6 pin to 4 pin adapter coming out of the radio. My friend wanted to be able to change 4 pin microphones if he wanted to, and also to be able to change radios and use same Heil microphone......All works very well and the 2970N4 now sounds very good, studio quality sound.

Thanks , Bob emailed me back, the unit will have equilization also. He said probably by the end of the year.

I like the hc-4 he made when i had it on the ts-50 kenwood.
Is there a way to run the hc-4 on the cobra 29 ?
My understanding is it will not work.

If you could run it through an equalizer you can probably taper the response enough to make it sound clean. I don't know of anybody that is willing to make the modifications to the Cobra 29 without bypassing the audio chain to make it sound clean running the mic directly into the front of the radio.

Yes. Not worth the effort.

This would work.. Do you think it would sound ok without any equilazation or mixing ?

There's a lot of variables but basically it depends on how the radio has been set up and by whom. There's a guy near me that had a President Lincoln 2 set up for wideband audio by Mike's radio repair and he's got his pr781 going into a mixer and an equalizer and it sounds awful and he had another President Lincoln 2 done by Mark and the pr 781 plugged directly into it and sounded great without The Equalizer or mixer. Unfortunately he sold the good one and kept the bad one.

Give an inexperienced person an equalizer and a mixer and they can make any radio sound like shit.

Mikes radio sounds like shit after the customer got it home and used an external audio chain, so that makes Mike a bad tech??? That couldn't possibly be operator error with the audio gear. (Sarcasm)

You say the mark radio sounded great with the mic plugged directly into the radio. I'll bet it did because you took the operator error out of the equation. Just more propaganda....

when he first got the radio back from Mike he tried plugging the pr 781 directly into the radio and it didn't exactly sound too stellar so that's when he started buying these additional components hoping to make it sound better but it just kept getting worse and worse so yes you're correct operator idiocy had a lot to do with it.

Once your radio has "opened up" for higher fidelity and using an external audio chain, there's alot of trial and error of many many hours listening to yourself on a dummy load, getting it dialed in to what you think sounds good!, nothing is just plug and play.
But that is the fun going down this rabbit hole.... At lest for me it is

You really want to sound like the HC-4???

whenever I hear one of them, I just spin the dial

My question is will the cobra 29 sound better with the heil hc-4 mic opossed to the stock cobra mic , by using the adapter box in the link above ?
Forget the mixing/ equalizing.

Lol... you make a good point. It did not have that sound on the ts-50 on AM its low level modulation.
I can relate to what you are saying , most of the guys on 80 meters have the same problem too much compression and the highs is like fingernails on a chalkboard
I think it would have been better if cb was FM like talking on the phone night/ day difference.

So if it was that bad why did he keep the mike radio and get rid of the mark radio. If the guy is an idiot as you say how can you put any faith in his results with each rig? He could have screwed up anything.

This is good info. equilazation is most important.
