Correct, except when kilomegacycles per second was in vogue [and giga
apparently had yet to become popular], it was abbreviated KMcs.
Technically, it should probably have been KMcps, which I seem to
remember it sometimes was. Kilo in that era was upper case, as in 500
Kcs. Then again the abbreviation Kcs was sometimes itself abbreviated
to Kc. All of this, and the ever popular "Colpitts Oscillator Question"
could be found on the FCC license exams of the day.
It's similar for capacitors. In that era, they were mainly mf for
microfarads [10^-6] or mmf for micromicrofarads [10^-12]. I do not
remember any that were kmf [kilomicrofarads - 10^3 mf]. No wonder we in
the USA are going metric inch by inch...

Skip,
The proper way to represent units with kilo (10 exp 3) in it is with a
lower case "k".
"m" stands for milli (10 exp -3) while "M" stands for Mega (10 exp 6).
Hz is capitalized because it is a man's name - Hertz.
