Perhaps you should use your connections and ask that very same
question to San Carlos Tower (KSQL), as they have pilots coming in
exactly like this, and they *ARE* a Class D airport.


No need to, I already know the answer. What makes you think NORCAL approach
makes a phone call to San Carlos tower to coordinate VFR arrivals?



In fact, it isn't only the TRACON that is doing this, KSFO
Tower does this as well. Constantly and Consistently, the following
is given to pilots:

"N123CM, leaving Class Bravo airspace to the south, radar services
terminated, maintain your present beacon code, contact San Carlos
Tower, 119.0."


That instruction tells you that San Francisco tower makes a phone call to
San Carlos tower to coordinate VFR arrivals?



Want proof of it, hit up the KSFO Tower feed at LiveATC.


Interfacility phone calls are on LiveATC?



Now, I haven't visited KSQL so I don't know if they have BRITE, but from
my
tour of NCT, controllers there told us that it is done so the tower
knows who is who as they drop below the Class B floor.


What would be the point in telling aircraft to maintain their present beacon
code if SQL tower had no radar?



For some they do
call the tower to let them know who is coming in (pending how the
traffic load is), some they don't. But it is a standard practice
happening at one of the busiest centralized TRACONs in the airspace.


More likely a misunderstanding on your part.
