Audio or carrier

[295 antenna]

Heres a fun Topic for Discussion ,

What matters more ? Audio or carrier? Using the formula that it takes 5 dBs to make one s unit on a radio.

Audio is everything but what do I know,, I'm a SSB'er.

Audio vs. Carrier...Audio all the way! The missing proponent here is the Antanna system. Without a proper antenna system, neither means anything.

I have seen guys with a lot of audio being able to come in over another ones carrier. so to me audio will be the biggest help when talking.

[Blue Ox2]

Absolutely. Audio is the best with a properly matched, well tuned,
and high enough antenna. The antenna is key. Without good ears
nobody gonna hear ya anyway.

definitely audio what good is a big carrier with low audio

[KP68]

Well, they go hand in hand. For me it's all about the proper ratio, audio to carrier 4:1. Just to toss out numbers say I have a 10 watt dead key, I would bring up my audio to just around 40 watts PEP. I incorporate a little bit of asymmetry so I can go above the 4:1, say 50-60 watts PEP without carrier pinching. My oscilloscopes are my bible. All depends on how you want to sound. Me personally, I strive to be as clean and clear as possible.

Awesome. We are looking for the clean, positive, strong signal.
I am looking forward to getting my IMax 2000 up so I can do some real
talkin' !

Oh heck, I just noticed how relatively close you are to me. Cool man, maybe if you are ever out my way we could say howdy in person. I am about 12 miles south east of downtown Pittsburgh. Peace.

Some great food for thought ! I also look for good clean audio and a strong signal

[-=PEAKABOO=-]

It takes 6 dB to increase by 1 s unit, 6 dB happens when power is multiplied x 4. 100 % modulation can only be achieved with a 4:1 ratio any modulation above you have to very careful or you will have distortion. Its possible to make well over a 100% modulation and still have asymmetry but most people run a low carrier and lots of swing and this is trashy 99% of the time. The other thing to consider is that the receiving radio can only demodulate about 150% of modulation so anything above that they could not tell anyway. Someone running a 1 watt carrier and 50 watts swing will get their radio cut off by someone running a 10-12 carrier and 50 watts of swing. Clean is mean.

I like em both, audio to be heard, and signal to stomp on my locals.

[SemperFubar865]

I'm new to the radio world and have been researching my ads off and wouldnt mind a little disambiguation.

I've heard several places that not only is 1:4 carrier/swing ideal and cleanest. But also that carrier is literally what carries the signal where as swing is volume. If you have 2 guys with the same radio sitting next to each other, 1 has 12watt carrier and only 18 swing and the other has 2 what carrier and 30 swing the guy with 30 swing will look good with the needle swinging and blast the guy aitting next to his ears off (to the point where nobody can understand a fan word he's saying. Like more than half the truckers on the road), but wont make it more than a mile or 2. While the guy with 12W carrier and 18W swing will sound really quiet as a mouse and be bowled over by everyone else. But the people 10-12 miles away will be able to hear, and talk over, him as well.

Is this true?

I have a cobra 29 that's a brick that I would love to use for experiments and mods. It's not like I can kill it much worse. But I've heard if you follow the MOSFET mod instructions it makes a very dirty splatterbox that's overmodulated, loud the the point of being indistinguishable/undescernable, swings but doesn't get out very much, hemorages across all the channels AND peoples TV's, HiFis, the PA in walmart and mama Ethel country kitchen where the family with small children is trying to eat lunch in peach hearing you cuss about the Prius **Censored**, etc.

I want a good clean radio that gets down the road but also shares it with other people. I want to respectfully stay on my channel, not splatter, not bleed, not talk over everyone. If I'm getting 30 watts of swing I would prefer to have a carrier of at least 7 or 8. Is it possible?

Hello SemperFubar865 im not sure what your getting at 1:4 carrier ? Antenna match ? Any way im sure somebody here can give you a better answer than me,,While your here why dont you stop by here http://www.cbradiotalk.com/viewforum.php?f=89 and tell us about yourself and we can all say hello.

[MDYoungblood]

The 1:4 ratio you are referencing is for RF power to feed an amplifier. Depending on who or how the radio was adjusted most times the meter is reading "fake" wattage caused by CMC (common mode current).
Go ahead and play with that 29 (not like they are going obsolete), like you said you can't kill it anymore than it is now. I'd get one of those cheap dongle SDR's and use it as a analyzer so you can see what the changes you make are doing. Build a dummy load too so your not transmitting over the air.
