K60XV -> ALC closed loop?

David Walker-8
Hello all.

On the first page of the K60XV manual says:  "... The K60XV's low-level
output is nominally 0 dBm (1 milliwatt), adjustable using the K2's POWER
control.  More importantly, the K60XV provides full closed-loop ALC that
works in both SSB and CW modes. ..."

Does this mean that the ALC will regulate the K2's power output more
accurately?  At the moment on my K2 will run 100w on SSB regardless of
my PO Setting.  I have to be in ALC to be able to reduce the power.  
This only occurs only on the 40mx band - all other bands the power
control on SSB is fine.

Cheers,

Dave

Dave,

That reference to a closed loop ALC with the K60XV applies only to the low
power transverter outputs of the K60XV.  It will not modify the ALC action
for the normal HF outputs.

Your lack of power control on 40 meter SSB is quite another matter.  It
could possibly be an oscillation occurring near 40 meters.  The KPA100UPKT
upgrade was developed because of an oscillation that could occur at 40
meters, so you may want to consider adding that upgrade as a first course of
action.  You could have a problem with the ALC on the KSB2 board, but I
would think it would show up on other bands if that were the source of your
strange behavior.

73,
Don W3FPR
