K2 ALIGNMENT & TEST, PART I....R1 ADJUSTMENT ??

[Ken J.]

Hello Elecraft K2 Builders....


Page 47 says to adjust R1 for a suggested setting of 3.80 volts. The maximum I can get is 3.79 at "full" rotation.

Supply voltage is 13.8V on the K2 voltmeter.

Any comments/suggestions much appreciated.

THANKS !!

Ken,

3.79 is nominally 3.8 volts.  However, since your 8 volt regulator is on the
lower side of tolerance rather than the high side, I suggest setting the AGC
Threshold for 3.7 or 3.75 volts - either will work and after you complete
your K2 you may want to optimize the AGC Threshold for maximum receiver
sensitivity.  Ask about that when you are ready - or check the archives for
the optimizing procedure.

73,
Don W3FPR
