Educated guess.  It seemed the likely answer, and I'm used to
unexplained acronyms all over the place in my fields of work
(electronics and video production).  But every now and them something
stumps me.

Since we're already off topic, and there's probably an old radio
engineer on this list, I'll put forward my own OT, hopefully without
upsetting anybody:

I'm still stumped by three acronyms found on an old radio mixing desk,
though.  NOL, ROL, and POL found on the attenuator pad on the meter
bridge.  NOL set the meter with the standard attenuation, 0VU equals
+8dBm (yes, it's that old that it's +8 and genuinely uses dBm).  ROL
attenuates it by 8dB, so 0VU is at +16dBM.  POL attenuates it by 12dB,
for 0VU at +20dBm.  I can only guess at that the abbreviations might
stand for, as the service manual makes no mention of them.  NOL may be
normal output level, ROL could be reserve output level, and POL peak
output levels.  But I don't really know.  Nor do I know what maximum
transmission levels the station would have set back in the late 1960s,
or early 1970s, in Australia, to confirm it that way, either.
