[Elecraft] K2 AGC/S Meter

[Tim Rife]

Building K2 S/N 6430 and at page 48, AGC and S meter alignment.  I can only
get a maximum of 3.60V from the pin 5 of U2 with R1 set at its ccw limit.
Additionally, for S meter alignment, both CAL S LO and S HI I am not seeing
the LEDs illuminate at all with either dot or bar settings.  All other tests
up to this point have worked as described.  Any thoughts on where to look?

 

Thanks,

 

Tim
