Measured on the radio, steady carrier for three seconds:
RM1=0 RM2=unsupported RM3=0 RM4=9→18→21→22 RM5=208 flat RM6=0
RM4 is the index that RAMPS with the output, so RM4 is the power meter. RM5 sat
at 208 from the first sample to the last, unmoved by the power — that is not SWR
on an operator reading 1.1, and 208/255 is exactly the 81 that appeared on the
bar. Borrowing the FT-991A's table, which puts SWR on RM5, is what put it there.
SWR now reads RM6. It stayed at 0 throughout, which is CONSISTENT with a 1.1
match but does not prove the index — only a deliberate mismatch would, and I am
not asking for that. A bar at zero on a good antenna is honest; 81 was actively
misleading.
The measurement is written into the code next to the mapping, so the next person
sees the evidence rather than a table copied from another model.
