Transmit, receive or both? You can't rule out the PS entirely if its
only on transmit but you have the added possibility of rf getting in via
the mic, etc.

Yep, scope it under load. You can even use a DMM or VTVM set to AC. Of
course you need to know the original specs or a ballpark idea how much
ripple (%-wise) is to be anticipated in order for the readings to be
meaningful.
