So what is the benefit of switching the caps in a brand new radio?
Like this guy did in this new 6666
Search for Goldfinger CB Audio Mods - you'll see a plethora, tons, loads, a landfill - full of links, tips tricks and tints, to the various flavored "Colorization" of the Audio Mods done to the radio like shown above.
All done, to "widen" the frequency band pass, open up the audio band width, open up the filtered audio path that this radio has, just for more spectral artifacts and more noise for others to listen to on the other channels next to the frequency this guy is on.
So you "widen" the audio signals bandwidth, what you
DON'T gain, is everyone else's radio will hear him sound like - meaning that they aren't all set up to HEAR what that radio will produce.
For some, if you think about it, many will hear a radio that although is winder in bandwidth, sounds
weaker because their radios' own Reception bandwidth is narrow, so they only hear the narrow spectrum of that same signal - not all the information contained within the signal is conveyed into the listeners ear.
Even if they could, widen their radios own receive, a lot more noise also arrives in, from that extra width of spectrum that is; not just signal - it's including the ambient noise the signal has with it in the listeners receive.
This is AM Sir, not FM - you have carrier - not capture ratio...
A good example of this would be to listen to an FM station in STEREO, then press the MONO switch - you lose a lot of ambiance and fidelity - it's lost because of the mono-phased, reception.
Another way is to use a LOUDNESS button on the same stereo - using it, you get some Bass and Treble enhancement - then turn it off - everything seems to sound more more "flat".
Unless you like to play music, the effort is not always worth the price in the performance hits, like heat and power.
Yes, I said power - and heat - both are a necessary result of the effort.
Takes a lot more energy input into the radio to push watts with a larger spectrum of information than a narrow filter band pass one does.
Put this into your perspective of being the listener of, for and on, those other CB's.- you only hear what YOUR radio will pass thru it's filters, so if your looking for high-performance sound quality - look elsewhere, Become a DJ, or even work at a radio station - you'll get a better respect for the equipment used.
