There were changes to the layout since we went from discrete components (Diodes D2 & D4) to
IC (IC, U15). The “Transmitter portion” was not altered by the layout changes since Transmit
output power, Transmit frequency and Transmit modulation, were not affected.

Below are software changes
       On the Tx side, changes were made to the FM modulation waveform (digital shaping
        filter).
     On the Rx side, changes were made to the demodulation filter (digital shaping filter).

Change current Modular equipment approval to Single Modular approval


Please contact me if you have any questions or need further information regarding this application.
