Ten-codes, especially "10-4" (meaning "understood") first reached public recognition in the mid- to late-1950s through the television series Highway Patrol, with Broderick Crawford.
The S stands for "Strength". Strength is an assessment of how powerful the received signal is at the receiving location. Although an accurate signal strength meter can determine a quantitative value for signal strength, in practice this portion of the RST code is a qualitative assessment, often made based on the S meter of the radio receiver at the location of signal reception.
Historically “10-codes” and “signal codes” were used when radios were less reliable and frequent repetition was required. These codes were rarely uniform even between local agencies. Most used “10-4” to mean “acknowledged”, for example, but some agencies used it as “message ends”.

Plain language is generally preferred in such cases (presumably via radiotelephone), but the various codes provide a succinct method of communicating to a doctor the nature of the ...
The Q-code is a standardised collection of three-letter codes that each start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio.
