[Elecraft] KX3 TX Problem

[Don Wilhelm]

Dave,
I suspect he is having problems with the Trnasmit Carrier Null. That 
procedure is normally done at the factory since it needs a spectrum 
analyzer to do it correctly.  If he has access to a spectrum analyzer he 
should ask support to send the complete instructions.  See page 34 in 
the manual.

When the closes the CW key it puts out 10 to 12 watts and stays at that level. In LSB, he hits PTT and gets the same 3 to 4 watts out without an mic audio. Sometimes the KX3 power out on the display agrees with his watt meter. At other times he does not see any power out indication on the KX3 display. In VOX he gets the same results however, he does see a quick "High Current" message flash up very quickly on the display when he keys it. Any ideas would be greatly appreciated. TNX es 73, Dave N8AG
