Check that a long lead from the KSYN3 or KREF3 modules aren't shorted against the bare metal they mount to. That was my problem. One cap had a lead that was too long and was touching. Rob NV5E K3 #1417

The rig seems to power up OK, but returns error messages when I do the Synthesizer Calibration. It returns Err VCO with E 00374 data and/or ERR VC4 with E 00039 data. I checked the seating of the oscillator, the KREF3 and KSYN3 modules and the three TMP cables, but the results are the same. What is going on and what can I do? Thank you. 73, Phil Shepard NS7P _________________________________________________________________ See how Windows connects the people, information, and fun that are part of your life. http://clk.atdmt.com/MRT/go/msnnkwxp1020093175mrt/direct/01/_______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
