Greetings All, I'm building K2 SN 4245.
When setting the AGC threshold I was not able to get 3.8 volts on pin 5 of U2 as described in the manual. The voltage varied from 2.60 to 3.78 when adjusting R1 to the extreme settings. Is this close enough or should I have more room for adjustment?
I have a faily good DMM, and it compares very closely to the K2 internal meter, and when checking values on 1% tolerance resisters. All other checks to date have been fine.
Thanks and 73,
Mike, W8ENG
