The one-shot survey fired as the transmission began and caught the meters still
at rest — RM4=13 and everything else zero, which identifies nothing. And the
operator's reading points the other way: the bar showing 81 tracks his 100 W,
while the one labelled power sat at 8.
What names a meter is which index FOLLOWS the power over a few seconds of steady
carrier, so the survey now samples on every poll while transmitting, capped at a
dozen lines. Two seconds of tune will settle it.
Still not guessing at the mapping: the numbers will say which index is power and
which is SWR on this radio, and it gets corrected then.
