check this amplifier out

hi everybody,

is this power amplifier design below a FM or AM power amplifier. is this a linear amplifier. the link to the power amplifier is below

The transistor is biased into class AB operation when volts are applied to the key input.

This amplifier is suitable for AM, FM or SSB.
It could be used in class C without bias to the base of the transistor for FM operation, better output filtering would probably be required to reduce harmonic output to a reasonable level.

This amplifier is designed for radioamateurs 2m band. Besides AM, FM and SSB it can be used for CW (telegraphy).
