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.
