AGC question

[Larry Naumann]

I am building a K2 and when I try to adjust the AGC voltage the most I can get is just under 3.8 volts, about 3.7 is what I can get. Is this okay or do I have a problem somehwere?
Thanks
Larry

Larry,

This is a frequently asked question - and it occurs when the 8 volt
supply rail is on the low side of its tolerance range.  If you cannot
get it up to 3.8, then leave it set at the highest setting.

No problem.  The value quoted in the manual isn't actually achievable
for some combinations of component tolerances.  Originally the preset
was fixed, and they've quoted the nominal voltage when it is set to maximum.
