Go up 3 kc, please

It is _not_ a pluralization. It is k(ilo)c(cycles-per-)s(econd).
The scientific notation for "X per Z" is "X/Z". Ergo, "cycles per
second" (cps) is "c/s". Thousand(s) of cycles per second is "kc/s".
The crude shorthand commonly used in ham radio is (was) "kcs"(, or "mcs")
-- probably due to morse code usage influence.
The pedantic argument back in the Olde Days was that a QSL card
confirming a QSO on "7180 kc" was wrong. (Just as "73s" on the
same QSL card was {and still is} "wrong".)

"7180 kc" is seven million one hundred and eighty thousand cycles.
Period. It could be 2 cycles today, 17 tomorrow, 6 the day after,
400 next week -- and, so on until the total number of cycles are
accumulated.

It's not until the "per Unit Of Time" is specified that we have
a _frequency_ .

(But, then, I think the QSL card should've stated
"41.783 Meter Wavelength".)
