[Elecraft] Control board diode

[Andy McMullin]

Hi All,

I acquired my K2 pre-loved (second-hand) and it seems to be working just fine.

However, today I started working on installing a new option into it and I noticed that the diode D1 on the control board has been disconnected at one end (but left soldered in at the other end - so it hangs off the board). 

Can someone enlighten me as to why this might have been done? I've looked through the manuals and haven't spotted it as a step in fitting any of the options.

Thanks in advance.
