    I can't speak for what or how others write but I'll take a swipe at clearing it up.
    Results are the only things to take seriously and the only things to pay for.

    My first post said to put something inside the amp to reduce the drive in such a way that it would not reduce the good reception of the radio.
    It had no explanation because it would have been very long and is best handled using accurate free online calculators, which is what I do to save 15 minutes, pencil and paper, calculator, and getting out a thick book to check my work.
    Additionally, a 'qualified' technician should do that work, both deciding what type of attenuator and the parts for it as well as where to insert it in the amp. Traditionally an engineer did this but techncians are expected to know it these days. Sadly it's not the case for hacks. Nothing to confuse, but find the right technician or find the regret.

    My second post, a comment to the post of Meteorgray, just gave a fully described example, showing my work, of how to use a length of wire and auxiliary battery to avoid overloading an alternator when using a large amplifier that wants 100 Amps.
    It was as simple and straightforward as possible. It's not for the rank beginner but no one should be impressed by it at all. It's at the level of a beginner at an electronics 2-year trade school.
    Even if it's rarely used (because people always want to pay more for 'high tech' solutions), there's no magic expressed or implied, just the most fundamental arithmetic, Ohms law, and wire gauge tables. It could be learned in one evening by anyone here, if someone would explain 1-on-1 with a basic book.

    I don't know what exactly 'mark speak' means or who this Mark is, but without reference to that, a technican's explanation or dialog should never intentionally confuse. It might seem impressive, but don't be impressed until the statements can be checked or confirmed by someone you know to have real knowledge. If they laugh then so should you.

    Electronics/radio a totally different trade than trucking so it may have things not yet understood by the recipient and it may seem much more mysterious than it really is. The barn doors are therefore wide open to charlatans of the occult and snake oil salesmen.

    Is what's written or said the kind of high speed technobabble full of made-up words, unprofessional slang/vernacular and ghetto terms for acts, parts, and other objects? Are a few errors intentionally babbled-in or crucial facts left unspoken so that no knowledge transfer or learning is given the customer? Run away!

    Many youtube CB shop videos contain this clownishness along with bombastic bragging ("Only ME!" , "I myself invented...") - and cutting down competing shops. These should only be viewed for entertainment, not taken seriously.

    That is different than what I offer. All real words for real things, nothing hidden, just fact. I have no axe to grind and do not perform CB repairs except my own. Not that I'd refuse a friend but I'm finally retired from a diverse and fruitful high tech career where only the observed and measured results mattered, and I hope that my comments about electronics are useful.

    There I fixed it. XD

    My bad choice of words maybe. How about competent? Neither are absolutes.

    To claim oneself qualified without proof is the pfft thing.

    Verifiable proof of knowledge or accomplishments attested to by a recognized authority, work that stands up to close scrutiny, industry certifications, or a degree, that is another thing.

    I meant the latter. The 'acceptable' technician will have work that stands up to close scrutiny. :D

    Look I'm not bashing you, but it is funny to see qualified used with the words cb radio,

    CentralScrutinizer, it's a pretty neat idea to use an auxiliary 12 volt battery to help supply a big amp with big watts. It isn't a complicated "fix" at all, just a little straightforward wiring and a battery to avoid having to install a second alternator and/or whatever.

    About the attenuator, I don't know any "qualified" techs, so I like to leave the covers on my equipment.

    Thanks for the response!

    I didn't think you were bashing. I think I agree with you. I find the same humor, double so by qualifying the word 'qualified' by ptuuing it in quotes. I guess I like or respect the old days where the FCC General Radiotelephone license (GROL) was required for fixing CB radios and a lot of other transmitters.

    I know this is probably not what you want to hear, but if it were me, I would buy a radio that has a variable rf power control , like a Galaxy 929. This feature would allow you to adjust the carrier/ deadkey to a level between 1/2 watt to 4 watts. From my experience you are not going to run the amp 100 % of the time, and when you are not using the amp it would be better to have radio set at 4 watts instead of a lower level like 1 watt.
