Pure signal or auto ATT issue. 300Khz wide splatter
Posted: Fri Nov 24, 2023 4:03 pm
I've found an issue with pure signal, very visible, when using 2TONE.
If you adjust pure signal at a very low drive level and then you try to adjust for a full power output, PS produces a very wide 300Khz splatter/spike while auto ATT is trying to find the correct value.
Same issue, but not as clearly visible, when PS auto adjusts using your modulation.
Tested in my Anan 7000DLE/Thetis 2.10.3.4 and also in an Anan 7000MK2/Thetis 2.10.2.2 from a friend of mine.
First time I saw this issue was 15 days ago when going from low to high drive power on 15m. After the spike/splatter, one of the LDMOS transistors in my power amplifier was damaged because of a fast SWR trip.
Is anyone else experiencing the same issue?
