And no you do not have to blow your whistle to bring in a sub. That is optional at best and unnecessary most of the time.

The two statements in pink are obviously linked. Rut sometimes fails to note stuff like that when he pontificates.

For any locale or state that DOES use NFHS mechanics, one DOES blow the whistle when bringing in subs. The new NFHS manual says so on pages 40 and 77.
2.4.5 F and 3.4.5 G
1. Ensure that it is appropriate to beckon substitutes ...
2. Sound his/her whistle, raise an open hand.
3. Motion for the substitutes to enter the court.
4. Keep the other hand raised (stop-clock signal) until the substitution(s) is completed and play may begin.

Also these two sections cover the mechanics of which official brings in the subs.
For two-man it is "the official near the table, typically the Trail," (2.4.5B) while in 3-man the book says, "Generally, the Trail will acknowledge and beckon substitutes onto the court, except when the Trail is administering a throw-in. In that case, the Center will beckon the substitutes.
... In such case, when in-bounding the ball in the back court, the Center will beckon substitutes (if the table side Trail beckons the substitutes as he/she transitions to new Lead, he/she should hand off the administration to the Center)." (3.4.5b&C)
