* This version implements a change to the modulation fidelity meter. In previous versions, the modulation fidelity reading
  would increase if the symbol deviation were other than 1800 Hz. Now the symbol deviation and modulation fidelity readings
  are separate from one another.

* The PassPort(r) option (2975OPT19) has been updated. Bands 7, 8 and 9 were configured with a 5 MHz offset. They have been updated
  to have a 3 MHz offset. 

NOTE: The PassPort(r) option update requires a new Option file which can be obtained from the Aeroflex Customer Service department 800-835-2350.
