Joe,

Thanks for recalling this!

I also remember these was an issue with the wattemeter trim. It was only usable to 50 or 70 watts and someone recommended not calibrating past these values. Does anyone remember that issue?

All, 

As the latest versions of Angelia code which support PureSIgnal are based on Hermes code, they all contain the particular LPF switch points that the Hermes code does.  Some time back (I forget when exactly) Abhi determined that the ANAN-100D needs different switch points from Hermes when 12m operations are used.  I completely forgot about that when I created the PureSignal versions of code for Angelia and this improper switching exists in the current Angelia_v2.5 firmware, unfortunately. 

I will make the appropriate correction in a new Angelia_v2.6 firmware release immediately.   Hopefully that will cure this low power problem with the ANAN-100D on 12m.   Not having ANAN-100D here to test with is a distinct disadvantage when trying to write firmware code it, I must rely on others to test the firmware that relates to anything beyond the Angelia board itself in the ANAN-100D; I apologize for the inconvenience my coding oversight has caused on this issue.
