How to measure the AGC voltage on a NetClock/2 with a beige enclosure
The top cover of the clock needs to be removed to access the AGC test points located on the receiver board. Turn the clock upside down and remove the two indented screws that hold the bottom cover to the top cover. Turn the clock back upright and carefully remove the top cover. Connect a DC voltmeter to the AGC test points. The AGC test points are located on the top PC board. The Black probe should go to TP 3, and the red probe should go to TP 5. The AGC voltage is approximately 2.3 VDC at a field strength of 100 µV/meter using a properly-oriented Model 8219 Loop Antenna and Model 8207 Preamplifier.
