The relevant section is §97.119 Station identification. The call of the
station must be used, "an indicator
consisting of the call sign assigned to the control operator's station must
be included after the call sign."

As I read it, that paragraph (3) applies only when the operator's
license class exceeds that of the station licensee... and most seem to
feel that it's required only if you're transmitting beyond the
privilege level allowed by the station license.

However, I don't think the FCC prohibits one amateur from lending his
equipment to another. So
you could take the position that the station owner has lent his equipment to
you, and during the loan,
it is your station, so you only have to use your call sign.

That seems to be the usual convention.

There seem to be several common practices, which I believe (speaking
*not* as a lawyer) fall within the scope of what the FCC considers a
reasonable interpretation of the rules:

- Use your own station callsign (the "borrowing/lending equipment"
concept). This makes you fully responsible for the transmission.

- Use the station's own callsign, only. This seems to be legitimate
if you're operating with the station owner's permission, and are
transmitting within the privileges covered by the station's
licensee or trustee (and your own, if you don't have a higher-
privileged control operator present). This is a common approach
used for transmitting at a club station... you use the club station
ID.

- Use the station's callsign, slash, your own callsign. You'd do
this if you want to actually ID the location you're transmitting
from (e.g. a club station or that of a friend), but you're
transmitting on frequencies which are allowed by your own operator
class but not by the station licensee's class.
