a. The "bandwidth" of your transmission is limited to 200 KHz, centered
on the actual operating frequency. Since 200 KHz is enough spectrum
space for several different FM stations, this is a "generous" limitation de-
signed to accommodate cruder FM devices. Properly built and adjusted,
the FM25B kit operates well within this limit. In fact, its signal should
sound no "wider" than any other FM station when listening on an ordinary
FM radio.

b. FCC Rule 15.215(a) says: "Unless otherwise stated, there are no re-
strictions as to the types of operations permitted under these sections."
This general provision appears to leave you free to use your FM stereo
transmitter in a manner similar to operations of an FM broadcasting sta-
tion, or to use it for any other non-interfering, practical application.

c. FCC Rule 15.5: General conditions of operation: "(b) Operation...is
subject to the conditions that no harmful interference is caused and that
interference must be accepted that may be caused by the operation of an
authorized radio station, by another intentional or unintentional radiator,
by industrial, scientific and medical equipment, or by an incidental radia-
tor. (c) The operator of a radio frequency device shall be required to
cease operating the device upon notification by a Commission representa-
tive that the device is causing harmful interference."
