[Elecraft] KAT500 operation?

[Fred Jensen]

Well, someone who actually knows about this needs to weigh in.  I recall 
a list thread about this and changes being made in the latest firmware 
to accommodate those who wanted the KAT500 to follow the current 
frequency of the K3, without making any RF.  Apparently there was a 
downside ... KAT500 clicked some while tuning, which I guess annoyed 
some.  I'm beyond half-deaf and I run my radios with headphones all the 
time so I don't hear anything from the KAT500 [or fans in the KPA500]. 
"Elecraft Standard Practice" in these situations seems to be, "Add a 
K3/KAT500 menu option to turn whatever on/off."  Possibly that might be 
the answer here

Not going to put money on it, but my guess is ... that's what they've done."
