APPENDIX A
Cautions
The board drive level is very low and excessive drive level
will destroy the transistor. If used with a transmitter, be
careful with your power control as some transmitters have
very high power spikes at startup due to a badly designed
ALC. It is a better idea is to put a power attenuator ahead of
this amplifier to protect against overdrive.
