[Elecraft] KIO2 - sidetone blues -- less blue

[Eric Manning]

Managed to put the Q5 gate lead onto U8 pin 4 instead of
RP7, & now we have sidetone, Houston.
Only thing is, it's much lower volume than before. I wonder why that
is??

I had the Rev A control board so I had to hack it. Now I'm damned if I
can get the !@#%  sidetone to work.
I have firmware rev 2.01, 

I changed the menu item to U8 pin 4, 

I can hear the KIO2 oscillator on 16.9 MHz, 

I have inspected the hack umpty times -- it all looks fine to me, no
shorts or bridges visible. 

Heck, it's only one cut trace, one cap & 2 new wires, and only one
wire has to be right to get the sidetone I believe [Q5 gate to U8 pin
4].


And everything worked PERFECTLY before I started on this little exercise
=(


Any hints or thoughts??


The trace to be cut is a green band about 1 mm wide with black borders on
both sides, right? I checked for continuity from Q5 gate to U6 pin 25 and
there isn't any, so I think I did that right.
