The latest release of SPE Expert Controller (V1.2.1), and all earlier versions, work with the 1.5k-Taurus amplifier model. However, recent comms with SPE regarding specification missing from their Application Programmers Guide has identified that SPE Expert Controller isn’t identifying the Taurus model in its ‘Health information’ window. So instead of titling the window “SPE Expert 1.5k-Taurus Health” it will simply be titled “Health”. The upper value (Watts) for the “RF Power” bar-graph in the ‘RF Information’ window will be 2500 Watts and not scale according to the power level (High, Medium, Low) selected. I’ve updated the software so this will be fixed in the next release.

The next release will also include minor changes to the labelling of the SWR fields in the ‘RF Information’ window so it’s clearer to which SWR sensors within an SPE Expert amplifier they relate. The new labels will be “SWR (Before ATU)” and “SWR (After ATU)”. The spoken, audible report and associated ‘Settings | Announcements’ window fields have also been updated to align with this change.

The release of SPE Expert Controller version 1.2.1 has been successful and no issues have been reported. My plan was that the next release (V1.3.0) would be an update containing UI changes for macOS 26 (Tahoe) but I’m thinking in the interim I’ll push a version 1.2.2 containing the above changes.
