ARRL QST July 2021 Field Strength Meter Schematic; and, Correction.

Below is the Field Strength Meter Schematic Diagram from the July 2021 Edition of ARRL QST Article
'A Sensitive Field Strength Meter for Foxhunting', by Woody White - KZ4AK

Noted Mistakes:

01. The Pins and 'IN' and 'OUT' Labels of U2, the LM78L05 Voltage Regulator, are incorrect.

02. One Lead of R5, the Feedback Resistor of the Non-Inverting Amplifier U3, is incorrectly connected to Ground. R5 should be connected between Pins 3 and 4 of U3 to produce the 1 + R5/R3 Voltage Gain from U1, to drive the Meter beyond full Scale (before calibration).

03. The Polarity of the Analog Meter is missing. The Positive Terminal of the Meter should be connected to R7.

Below is a corrected Version of the above Field Strength Meter Schematic Diagram.
