STAGE GAIN CHARTS

Ref: Para 104, R-392 Manual

Connect VTVM or DVM between the diode load (red test jack J615) and ground.
Connect signal generator output to antenna (via 50 micro-micro farad cap) or
to internal points (via .05 microfarad cap); ensure sig gen ground is also connected
to receiver ground. Table signal generator voltages are the minimum and maximum
sig gen output required to generate -2.5 volts across the diode load.
