[Elecraft] headphones in phone jack makes meter go up ...

[Duncan Carter]

It could but I don't think it's too likely.  As far as misalignment is 
concerned, I think if you don't bend a pin and you carefully line up the 
pins and sockets and if the pins slide into the sockets freely as mine 
did, if there's any mis-alignment, there's a socket issue that's beyond 
my control.

Elecraft has circuit diagrams available on-line and I've spent quite a 
few hours lately studying them.  What I haven't seen are drawing of the 
circuit board traces which are common service information; having trace 
board drawings would really help in troubleshooting the problems.

I could, of course, just send it to Elecraft but that's not very 
appealing to me.  I've been a ham for fifty-five years and build, 
modified, ad repaired my own gear and other peoples.  I've done repairs 
and managed service depots for industrial vibration equipment.  One of 
the things that I've learned that if you send something with 
intermittent problems in for repair without knowing what is really 
wrong, there a good chance that you'll get it back without the problem 
really being cured.  I also have a good collection of test equipment.
