Let me know of you disagree with any of these conclusions
Last selftest: Both tinySA have same signal to noise at 30MHz with LNA on?
Attenuator test: Both tinySA have a good attenuator
400MHz test: same noise and same signal level for both tinySA
823MHz test: same noise and same signal level for both tinySA.
Conclusion
I do not see a difference between these two tinySA
What is happening?
