Mike, Are you measuring on the correct pin, and do you have the RF GAIN at full Clockwise rotation (Max gain)?
I see no indication that 8 volts should be measured for the AGC. The manual page 47 calls for setting the AGC Threshold pot to achieve a voltage of 3.80 volts as measured at Control Board U2 pin 5. If you are not able to adjust that high, check the soldering of Control Board RP6 and pot R1 carefully, make certain the resistance from Control Board P1 pin 6 to ground is close to zero (if it is higher, check the connectors), and lastly check the voltage available at the OUT terminal of Control Board U4. There are no active devices in this part of the circuit - it is just a resistive voltage divider with two legs and driven by the 8 volt supply rail. 73, Don W3FPR > -----Original Message----- > > Last night I completed what the manual calls "Assembly, Part I" of the > RF board.
