Note:

The following data to test in person, these data sheet is in 
a large heat sink can withstand 200W above measured, there 
is not enough cooling capacity, please do not limit, it's 
not safe.
The upgrade board test data,so it can be used for all HF 
Channel,
In 3 to 5 MHz this period, because of the low frequency, 
small inductance, lead to the gain has a certain loss, the 
output power is lower than 7 MHz this point.
