Hi,
All of the changes are covered in the changelog (see below).
- The latest 4.2 beta firmware is compatible with the ATS25-AMP.
- PSK decoding is supported.
When the new firmware is installed, you will need to make sure you select the correct receiver type in the configuration, otherwise the receiver will not operate as expected.
It should be noted that the additional frequency bands requires a hardware modification which is not so straight forward for the ATS25-AMP.
An outline of a possible modification is provided in the link below. Further discussions can be found on the forum.
