    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I have a Cobra 25 straight over of the box, untouched.

1. Do all radios need to be peaked and tweaked (normal use, no amps, etc.)? Does this radio need a golden screwdriver?

2. What is the best way to dial in the audio?

Thank you.

— Design, construction and operation put this new mic above similar mics.

Have now bought (2). May get more. Sound can be modified by removing inserts (not really recommended unless one’s voice is at either spectrum end).

Astatic 636 or RK-56 the others. 656 takes cues from each.

The Xtra positive switch sold me first. “Feel” and body material, second. Cord, third.

External Speaker also recommended. KES-5 or BC-20. (DSP Speaker would be best).

That term..... "peaking & tweaking" .... just bothers me.
And NOT because you asked about it @smittie ........ I understand what you are wanting to know.
If anything... what you want is an alignment... and a PROPER alignment.

"peaking" just builds this image in my mind of a guy with a screwdriver and a power meter, turning anything he has to inside the radio ... to make that power meter's needle go up!!!!!!!! And .... in Mandalorian terms.... "this is NOT the way!"

@KANE4109, back in the day (late '70s) every Tom, Dick and Harry was offering to open up a radio and turn the pots in the promise of better clarity and more power. Even then I hard my doubts but I never knew if there was any basis in truth.
Most of my background at this point is based on military experience. Never had to mess with making the audio sound decent. Just had to connect all the parts correctly.
Still sorting out the CB world again.

Thank you.

There seems to be very little Quality Control when if comes to CB radios. If you're really wanting something done to your radio, I would agree with the above about a proper alignment. However, on a non side band radio... Im not sure how much you are really gaining by said alignment. Back to the "Quality Control" I've seen many brand new untouched radios far off when it comes to SSB.
But to each their own. You may be able to achieve some "feel good" watts on the meter by a peak and tune, but for what? On proper test equipment, it may show you bleeding across half the band.
Get rid of that stock mic, but most importantly focus on the antenna.

Thanks @522.
It's not something I want to do. I'm inclined to leave the radio internal alone, get the antenna dialed in and figure out a way to perfect the audio.
I mostly wanted to confirm that what we did back in the day was kids playing at things we didn't really understand.

Usually a good idea unless you are 100% sure you have a tech that knows what they are doing. Too many just crank things up for more swing on the watt meter.

I know, I know, it's better to have a good sounding radio. But I doubt most of these guys actually have the right equipment to do it right.
Most users are running stock radios and somehow they survive.

get the antenna dialed in

Best bang for your buck. A good antenna install will make a big difference. When I used to be active in CB, I found most were using really crappy antennas, not tuned and usually stuck in a less than ideal location.

and figure out a way to perfect the audio.

Last CB I ran (many years ago) was bone stock. I connected it to a Motorola external speaker I already had installed in my truck. The larger speaker really helped voice intelligibility and volume.

I mostly wanted to confirm that what we did back in the day was kids playing at things we didn't really understand

There's a lot of people on here that can give you good advice.
If I was going to install a CB in my current truck, I'd make sure I did the following:
-Clean power off the battery, with the negative lead grounded close to the radio.
-Proper antenna installation. Since the mid 1990's I always ran a permanent NMO mount on the roof of the truck with a Larsen NMO27 antenna.
-Tune the antenna using the right tools. An SWR meter will work. Something like a NanoVNA is even better.
-Add a larger external speaker.

If you do all that, and still feel like you need a 'peak and tune', then go for it, but don't do the peak and tune first without having all the other stuff done. That's just pointless.

NINE FOOT mic cord?!?!

Makes it easier for some of these guys to keep talking on the radio while sitting on the crapper.

Thanks @mmckenna.
Mostly concerned about the outgoing audio. The little speaker is fine. It's about six inches from my ear given the mounting location.

The Jeep has a fiber glass roof which limits mounting locations. Mine is less than ideal but it'll have to do.

I might explore the world of mic a bit more. I definitely do not need nine feet of cord all over the cab of my truck.

I would not allow anyone to Peak and Tweak my new radio. I would pay extra for them not to open the box! Unless the radio was poorly tuned in the factory by the robots and software, there is nothing you need to do.

About 90% of the people you hear on the channels may sound like crap because they had some "tweaker" mess with their radio, or they have an overdriven mike and amplifier. There is nothing you can do to improve that. As far as SSB most stations should be on frequency unless they are using a ham radio with VFO or have modified the RX clarifier into a TX "slider". Again, leave you radio stock and stay in your lane.

the folks that make the radio did their best. it is probably as close as it can get.
handing the radio to someone that "knows stuff" would not be the best.
having a multi-tester and a scope, does not mean they know anything.
yes, you might get lucky and find a good guy, but what could he get even a 10% improvement will not really be noticed.
