Re: KPA3 12V Sense Modification

Robert Mccormack
Hi All,

Two K3s in the ZM1A shack,  #320 and #321 - both have the Revision B March 15 2009 modification.

Recently, #321 has refused to turn off - no problem with #320.

Checked the 1N4148 diode, tests OK but replaced it anyway.   #321 still refuses to turn off.
Has anyone else experienced this problem?

73, Ken ZL1AIH (at ZM1A in contests)
