The locking amp for IPM2C24X cavity was changing sensitivity in auto gain mode. This is a normal condition when the current in the cavity is ramping up. This sensitivity change was also occurring during static current running. The lockin amp associated with IPM2C24Y did not exhibit the same behavior. Obit lock was moved to IPM2C24B which is a digital receiver with a stripline bpm.
