I just uploaded into the fles section two files
main directory : https://ultralightdx.groups.io/g/main/files/Tabled%20comparison%20between%20L330%20and%20PL380.pdf
this is a comparison table of features between my old PL380 and my new PL330

https://ultralightdx.groups.io/g/main/files/3%20Radios,%20Reviews,%20Manuals/Tescun%20PL330%20special%20features.pdf
These are all special - hidden- features of the 3306 version of PL330 with updated information edited earlier this week
Hope that you are interested for that
