[Elecraft] K3 Caution when using an external monaural speaker

[Ron D'Eau Claire]

Yes, but it was also phased in at Aptos on Rev A boards at some point so,
while all Rev A and earlier boards need the mod, the more current K3's with
Rev A boards probably have had the mod made at the factory already. 

There's a way to check by just opening the K3's top cover shown in the
document.

According to the Enhancements and App Notes page at:

http://www.elecraft.com/K3/k3_app_notes.htm

"This modification is needed for all K3s shipped approximately before
01/12/09 containing either a Revision "XB" or Revision "A" KIO3
board."
