CB radios in the United States have come a long way since their introduction, with significant advancements in technology and equipment.

Early CB radios used vacuum tubes until 1965, when solid-state transistors became widely available, making walkie-talkie hand-held units more affordable.

The first CB radios had limited channel coverage, requiring plug-in quartz crystals to select operating frequencies, but with the introduction of "mixer" circuits, frequency-synthesized radios became possible, reducing cost and allowing full coverage of all 23 channels with a smaller number of crystals.

CB radios often feature various features, including an automatic noise limiter or noise blanker, which reduces background noise, and an automatic level control (ALC) that limits transmitter modulation level to reduce distortion.

Some CB radios also have a PA function, allowing them to drive an external speaker and act as a low-power public address system, or "bullhorn".

Microphone choices for CB radios include dynamic microphones, which use a magnetic coil and permanent magnet, and ceramic microphones, which use a piezoelectric element and are rugged, low-cost but high-impedance.

Here are some common microphone types used in CB radios:

Technology played a huge role in making CB radios accessible and functional.

The first CB radios used vacuum tubes, but it wasn't until 1965 that solid-state transmitters became widely available. This was thanks to the introduction of RF power-transistors.

Early CB radios had limited channel coverage, but plug-in quartz crystals helped select operating frequencies. More expensive units had a panel control to switch between channels.

Superheterodyne receivers were the norm in good-quality equipment, but low-cost units used super-regenerative receivers. This was a significant difference in quality and functionality.

Transistors made walkie-talkie hand-held units more affordable, and mixer circuits enabled frequency-synthesized radios in the mid-1960s. This reduced cost and allowed full coverage of all 23 channels with fewer crystals.

By the mid-1970s, crystal synthesis was replaced by PLL technology using ICs, enabling 40-channel sets with just one crystal. Almost all CB radios were AM-only, although some were single sideband sets.
