    Maybe not so much the future, but the here-and-now.

    Bad news for tweaknicians. Only seven internal adjustments in this radio.

    The Uniden PC88XL is the current Cobra 29-equivalent AM mobile CB from that brand. They're done with copying obsolete designs from decades ago. This thing is nearly 100 percent surface mount, and has a total of seven adjustable components.

    The component side of the circuit board is a bit like a desert. A few lumps here and there with a lot of empty flat area between.

    The transmitter has five adjustments, total. Six if you include the modulation limiter. The three cans are the filtering after the 7310 mixer chip. The MOSFET final has a trimpot for gate bias, and the output has a slug-tuned coil pretty much the same as most older AM CBs.

    The modulation limiter has a trimpot, conveniently labeled "AMC".

    The empty component positions appear to be for a weather-band feature, not installed in this radio.

    Move along folks, nothing to tweak here.

    More like, boy, we’d hate that America’s three million truck drivers might ought to be able to talk more than a mile.

    What the standard “means” deserves investigation.
    The divisor between what it says and what it does.

    The push in truck company “Safety” (sic) departments is that bureaucratic control of driver legal responsibilities is justified. You, the driver, certify legal documents . . . but only as “allowed” by the truck owner. (DOT or Insurance requirements cited.)

    The genuinely stupid among us buy electric cars (any) which can be remotely-controlled.

    The control of the vehicle by those not in operation of it is deemed of higher importance than the true responsibility of the driver. Private or Public workarounds. The citizen, undercut.

    All men are (not) created equal.

    As it’s time to push Americans off the stage to welcome in the half-Americans incapable of exercising rights.

    “Oh, sure, . . . it has a CB radio!”

    (The term “Citizen” no longer with any meaning).

    This is the future and its here. I guess either adapt or not. Cant hang onto the past. The 1970s ended 41 years ago. Time to move on.

    Bullshit. Ill keep running my 30 year old radios and dont need or want this garbage. Dont buy the junk and plaster the web with horrible reviews. Make that crap sit on shelves. Slap Uniden in their pocketbook and those fools wont do this again.
    This was the future too.

    Dude I talk on Brownings and Trams and own over 100 radios and only own 3 new radios. I'm saying this new stuff is the future.

    I enjoy living in the past and the future. It depends on what mood I’m in at any particular time.
