I ask the following because:
1. The rules in QST are ambiguous;
2. The people I have asked who should know the answer have differed in
their opinion.
In CQWW, are there High power, Single band, Assisted categories, or does
use of assistance automatically put one in the All-band slot?

I don't have an Ft-990, but... if it were me, I'd avoid the relay in the
FT-990 that keys the amplifier altogether. I'd go inside the rig,
find the voltage that's keying the rig's T/R relay (not necessarily
the voltage that keys the relay that keys the amp), and use it to
turn a HEXFET on/off to key the amp relay.
I've used similar setups with TS-930's and TS-940's and it works just
fine with my Alpha 76-PA (w/retro-fit QSK) and an Alpha 87 (I think
that's the model).
Good luck.
