Audio Equalizers

[riverrat373]

The kind of speaker you use makes a difference as well

Yeah, I know. I've tried many speakers lately and I have settled on an old Radio Shack speaker that came with my DX150 shortwave radio. It actually sounds pretty decent since it was designed for voice frequencies.

Mustang. I've got a Beringer 802. I bought it abot 2 year's ago in order to give my Madison a try at midfi. Along with a Shure sm 58, and an interface to tie it all together I'll bet you could guess how that experiment went?
I heard an eq could, and normally does an excellent job or improving one's recive.
Can you give me a layman's synopsis of how one tie's in the 802 (or any similar 3 band eq/mixer into a Madison in order to improve the RX? Thanks

It ain't rocket science. I bought 2 Radio Shack eq's with expander years ago for $20 a piece. I use one setup for channel 6 and SSB audio. I put the output of the left channel into the input of the right channel. This gives much more rejection above 3-4k and between 100-150htz. Trial and error method.
"Hi-Fi" CB, Ham, SW and AM broadcast stations sound fuller with a wide band radio and a expander. Again I use old RS base reflex speakers from a 100watt amp.
Most my gates are direct, but this one hifi. I know this is 8k+ bandwith, but it sound pretty good even on my 29.

Thanks 131.
Since I already own the Beringer 802, and all It's doing is collecting dust I've nothing to lose.
If I get results anything better than the stock rx on the madison I'd not only feel better about purchesing the 802, but put it to good use. I will certainly enjoy listening to SSB more than I already do. The stock madison has decent rx, but I suspect adding the eq should have it sounding much better (fuller.) I had a West mountain DSP speaker hooked up to the rig but couldn't pass up an offer to swap it for other goodies worth 4x more than what I paid for the speaker. I thought about buying another WM DSP speaker, but since the 802 isn't being used I might as well give it try.
After taking care of more pressing issues I'll take the 802 out of the closet, and give it a shot. Thanks for the info. 73's. PS. If I have any further questions I hope you wouldn't mind if I pm you when I'm ready to hook it up. I listened to your clip on my j7 which doesn't have good audio quality. And the clip sounded sweet. I plugged the headphones into the j7, and it (the clip) sonded awesome.

Something tells me an equalizer wouldn't be able to help this guy.

Did all that testing with his "box" on. The best the rig sounded was the very last recording with his box off.
What does that say about the box he's using? I'm curious as to why it says Mikes radio repair with the words Hi-Fi above it. To my knowledge Mike doesn't do Hi Fi direct injected, mmm modifications. He will to my knowledge work on radios that already have Been direct injected or have had an mmm added to a transceiver already. But as far as installing any of those devices I've never seen a single video in which he has done that work. On the contrary, he often comments about making a stock radio sound as well as it can when it came out of the box without all that Voodoo shit added to it. I always imagined him to be kind of a purist when it comes to fucking with those injected mmm types of modifications, and is not totally against them, but has mentioned quite a few of his videos how he is more of a purist and most transceivers don't need to be direct-injected excetera excetera excetera in order to sound good. I could be wrong. I'm only human. in actuality the radio sounded fairly decent when he shut off his box. I think there is a big clue in the video to his apparent audio issues. It's probably some class C piece of shit that's being over driven. He doesn't mentioned what type of box he is using during all those microphone changes. He also doesn't mention what his driving this box with. Is he driving it with 40 Watts pep and they 2 watt dead key? Yeah! There's a lot missing in order to come to a conclusion on why that radio sounded so poorly. But as I mentioned and I'm sure everyone else who watched it noticed it sounded fairly decent with the final microphone used and the Box turned off. It would have been interesting to hear how the radio sounded with each microphone he went through which I believe was approximately four or five different ones without the Box in the on position. I would venture to say the results would have been quite different (for the better in my opinion.) 73's

The customer told Mike he wanted it to sound HiFi with his mixer and his Heil PR781. I totally agree it needs to stay barefoot instead of running into the Texas Star 350 which Mike set the radio up for.
I thought it was pretty amusing nonetheless.

My lessons (learned here) taught me unless your transceiver is operating at 3 kilohertz wide (or wider) a Heil microphone, or any studio microphone for that matter and a mixer is not going to give you the maximum ability that it would if it were 3 kilohertz or wider. I tried that mid fi thingy with my Uniden Madison. I purchased a Behringer 802, Shure sm58, and an interface from some guy who builds them in Pennsylvania. $300 + only to learn that the mids and highs will be affected in a positive way if you're operating under 3 kilohertz, but if you're operating below that 3 kilohertz mark the Low's won't be detectable, and from my experience that's what the goal seems to be. The the mids and the highs are nice to change but if you can't affect the low then it's a useless waste of money. Just my two cents of course.
I would sell those three items I purchased, but think I'm going to keep them as I will be soon be owning a transceiver that does operate at 3 kilohertz, and the Behringer 802 and Shure sm58 might come in handy. As for the interface I'm not exactly sure what I'm going to do with it, but I am going to keep it. If I ever wideband a CB transceiver that interface just might come in handy. It's currently wired for a 5-pin Uniden, but can be rewired for any configuration. Live and learn. That's exactly what I did.

No offense intended but you clearly have a very harsh bias against Mike so you have less than zero credibility when discussing anything to do with Mike. Your about as credible as Thomas Edison with regards to dealing with Nikola Tesla! LOL Let us see how much business you can drive away from "Hard Drive" with your acrid rants against Mike. Too many people have used his services and had no problems for you to attempt to poison the well. You would have better luck convincing people Baden Powell was a raging pedophile and Communist sympathizer! Not to mention things get damaged in shipping and everyone makes a few lemons even Toyota pushes a few lemons out.It happens and usually, we give the person a chance to fix it or respond to charges of incompetence.

 

[Low_Boy]

Sounds to me like the real problem is that that guy does not know how to use a cobra 138 or any radio. LOL
Why don't I just crank up the monulation all the way. Daaaaaaaa. He deserves to be made fun of. His amp sure is being over driven also.

What was the other guy running? His radio sounded great.

Using an equalizer will improve audio; but that can only do so much. To get the full benefit from your radio (dunno what you are using) is to give it the 'Goldfinger' audio mod. This will widen both your receive and transmit audio bandwidth some, but enough to realize a real change.

YOU DO NOT WANT TO BE WIDENING THE AUDIO.

The stock audio is wide enough. You need to be reducing the lows, not increasing them, and you need to be peaking 2kHz to 2.1kHz.

TX audio with a lot of low end sounds nice and boomy but nobody can work out what the hell you're saying.

There's a video on Youtube on the Ham Nation channel where Bob Heil explains what you want to be aiming for. Hint: Its the complete opposite of what most CBers seem to want to sound like.

20 minute segment from 41 minutes.

I've watched that video over a year ago and I (like yourself) think one can learn lots from it.
Great clip to share.73

I don't pay enough attention to what particular members say about techs and or other members, but good looking out. Sticking up for Mike. I've spoken with Mike dozens of times over the three years plus that I've been sending him equipment. I know for a fact his feelings about wide banding and "hi-fi" CB radio.
I actually never noticed a pattern of rabbiporkchop either bashing or under minding Mikes work. I know without even having to ask. Mike made no such claim. His thoughts and feelings about these types of CB modifications are stated in many of his YouTube clips.
If the ear can't hear it why transmitt it. Is what I believe Mike to have stated on several occasions. HesH gone on record many times stating that unless you're a bat or have the hearing of one why bother. 73 s

Never heard Bob on ssb but his AM rig is about 8khz wide. Sounds good.

This is the other guy coming through my receive this morning. Not bad for a cheap $20.00 Chinese Mic.


He's running a Stryker 955

No bias on my end. I'm always referring business to Mike for recap jobs and basic repairs. I simply observe how something performs and sounds over the airwaves. A buddy of mine recorded it. I wasn't even there. Definitely funny though.
