[Elecraft] K3 - ERR PL 1

[Brett Howard]

If you're careful you can get the synthesizer boards out of the radio
without removing the subRX.  I just got done installing the stiffeners
onto my synthesizers and didn't have to remove the subRX to do so but
you do need to remove the 2 Meter internal transverter if you have that.

Also when you do this mod if you need to make sure that you do NOT
install the resistor where that document tells you to.  Instead use the
location that is outlined in this document:
http://www.elecraft.com/manual/ELECRAFT%20KSYN3%20Stiffener%20Mod%20Rev%
20D.pdf

As you read that second document you'll see that it shows you moving
that resistor to a new location.  I personally recommend just changing
out the resistor with a new SMT part of the correct value (thats what I
did).  But I just wanted to make sure you had a full picture of the
mods.

Actually to ensure that you have a full picture while you have the
synthesizers out you should also perform this mod:

Have fun!
