DX Engineering, DXE-7580FS-VA-2, 80M vertical antenna raising first time. Little scary but no issue. Been up there for 6 months without guy wires and been through couple of high windy (70 MPH) days without an issue.

Two MRF1k80 LDMOS combined to obtain 3KW RF output - its under testing.
Looks like a very rugged amplifier Mukesh. Lots of headroom and reserve in that build!
thanks Rob, I just finish optimizing it for linear operation, its avergaes out 2400 watts on almost all band, little less on 6 M,
