[Elecraft] AGC Threshold question - K2

2005-01-03 Thread Neal Campbell and Sarah Ferrell
Hi, I am just at the first alignment and test stage of my K2. Everything checked out just fine except the step where I am to adjust R1 on the control board for 3.80 v on pin 5 of U2. The highest I can get the voltage to go is 3.38v. Is this something to worry about? If so, any clues?

Neil, Yes you apparently have something wrong. The voltage measurement comes from a purely resistive network fed by 8 volts, and there is not much to troubleshooting it - that is if you can manage to probe the pins of R-Pak RP6. With the RF gain in the full clockwise setting, you should
