I have a couple of questions about readings I have collected during my present build process.
First: The procedure outlined for setting the AGC Threshold on page 47 recommends setting the voltage from U2 pin 5 to 3.8 volts by adjusting R-1. In the troubleshooting section Appendix E Page 6, the procedure recommends setting the voltage to 3.9 volts. As I understand it this is a initial adjustment that I will fine tune later and that I am just adjusting for a peak voltage. However the maximum I can adjust my U2 Pin 5 voltage is 3.78. Comments? Second: The IF Amplifier Alignment, outlines a procedure to tune the VFO to 7.000 MHz then with the L34 slug turned down 1 1/2 turns from the top of the can, adjust the L34 for signal peak. I hear a tone at 6,998 MHz and the audible tone is pretty solid for a full one and half turns in either direction on the L34. I hooked up a DMM to the headphone output and the voltage appears to peak at the top of the L34 can. Comments? Third: I remember seeing a posting that discussed a rather elaborate procedure to Calibrate the K2 S-meter using the Elecraft XG1. Or was I dreaming? Can someone point me in the right direction to speed up my search. 73, KI4DGH Chuck G. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
