Are they being nice or is their phasor obsolete?

Phasors can not be obsolete. They can be badly designed, hi-Q and
narrowband, but there is no real change in components (coils and caps and
vacuum caps) or design since the first directionals on AM were used at
WSUN
and WOR in the 20's.


If the Q is too high for an evolved transmission scheme, and cannot be
"adjusted" to a more broadband spec, the phasor is obsolete.

No, that is not obsolescence. That is just a design criteria. Any phasor can
be broadbanded.
