Too bad that not a single bug was fixed and in the current version "ExpertSDR2 v.1.3.1 Update6".
from 21.07.2020 for MacOS contains many more bugs. Transmission bandwidth of about 20kHz, "Transmitter Signal Analyser " without function.....! I had to undo the firmware update and do a "deep reset". Now I have problems to use my RM Italy BLA 350 because my audio (SSB) is corrupted, scratched, no full power, etc.!
The power amplifier works fine on my YAESU FT-991A and also on my YAESU FT dx 3000. I am now very dissatisfied and annoyed daily about the numerous errors and missing functions. Tuning is a catastrophe!!! Drive%, Tune% and the "Power Correction" in the option menu are a complete unreliable disaster!
Profiles are deleted or changed from the 2nd created PROC-profile on. I really don't know what is displayed correctly...!!! I ask for short term troubleshooting, especially when controlling the power amplifier.
If I do not hear anything from you until 15.08.2020, I expect you to refund the full purchase price (please do not pass it on to the dealer!!).
The software is optically really successful but not more. The SunSDR DX was purchased in May 2020. Currently I use my old YAESU FT dx 3000 which does everything reliably.
