So describe what is not working. Is the the attack, the hold or the decay and how is it not working?
I found on 80 during static crashes (like right now) that SSDR 1.2.1 SLOW mode was better than 1.2.17 and 1.3. While 1.3 has improved, the issue seems to be the hang before starting to release is too long for SSB and causes audio dropouts. This is with AGC-T at default 55 , 40 or 65. Trying to copy a signal below S9 results in audio degrading or dropping out some syllables.
1.21. slow would mitigate static crashes but not eliminate them. It did not degrade the audio.
I would suggest that they incorporate 5 settings, like PSDR off, fast, med, slow, and long.
Improvements I would suggest are to have a little faster release with a more gradual decay rather than long release with fast decay.
I can do a recording of how 1.3 degrades the audio for those that are interested.
