K3 # 282

[Nand Kishore]

Did a K3DSPLPF mod along with an addition of Xtal filter in KRX3.
Also did SS H/W change.

At the closing phase noticed a capacitor fallen on work table.
Went ahead with assy.after looking for a missing capacitor in
available visible areas.Gave up looking after an hour.This was
yesterday night.K3 seems to be working fine, made one CW and
one RTTY qso before going qrt.

Brought the capacitor to my work place which has an avionics
shop,confirmed that the component is indeed a capacitor,
measured the value.I am told the value is 5.6 pf.
Now where could the capacitor have fallen out of ?
It is a mystery to me.

I would contact K3support at elecraft.com, providing your K3 S/N plus all installed options.  They should be able to provide you a list of all possible component locations with that value.  Then it will be a matter of inspecting all locations physically to find the one missing the capacitor.

I cannot believe that a capacitor would actually come unsoldered and fall
off a pcb; it's more likely that it was packed loose for some odd reason and
just happened to drop out when you opened up the box.  I've never come
across a component not taking any solder at all having passed thro a solder
wave.  Does it look like it has been soldered at some stage?
