RF output power:

1.8-25 MHz28.29.9 MHz
AM:~40 W (80 W input)~40 W (80 W input)
FM:~50 W (120 W input)~50 W (120 W input)
SSB (PEP):~100 W (240 W input)~75 W (160 W input)
CW (DC):~100 W (240 W input)~75 W (160 W input)

NB1! AM and FM transmit requires the optional AM/FM unit

NB2! The PA is very conservatively driven, and can produce significantly
higher output power if properly peaked and tuned.
