Hello,
i have tested on 20,40,80 and 2m with my SUNSDR2pro, SPE Expert 1K-FA and RM ITALY LA 250. I used the full Tune Power. The result for RF is excellent. For VHF I will still change the attenuator of the LA 250 in order to achieve the 200 watts.

20m in 15,5 W out 841 W
40m in 14,3 W out 1.161 W
80m in 14,4 W out 904 W
2m in 4 W out 106 W
