Are you using AGC to control the drive level? You should NOT do that.
Ten Tec makes a point of this in their manual. ALWAYS set the drive
level using the power output control of the transceiver that drives it.
If you use ALC, use it ONLY as fall-back protection in the event that
something goes wrong.
