Option W1 Level Detector - Provides 0 to +5 VDC level indication for -60 to -30 dBm 140 MHz output.

The DC voltage comes out on pin 8 of the DB9 connector, J10, with pin 5 being ground. The impedance of

the 0 to +5 VDC level indication signal is 1k. The relation between the change in output level and the

change in DC voltage is linear.
