[Elecraft] K2/KPA/KAT operation WITHOUT high-current power

[Chris Kimball]

My rig is a K2 with a KPA/KAT in a separate enclosure.  The rig will operate
at 10W or less with the power turned down, but I'm taking additional current
drain from the presence of the KPA/KAT.  

I'd like to simply disconnect the high-current supply from the KPA/KAT to
operate a low power and lower current drain without completely disconnecting
the KPA/KAT.  (The K2 has the low power antenna tuner.)

This  seems reasonable from the KPA manual and the KAT should become a
straight through connection.  However, the KPA schematic says that the
passive low pass filter will remain in place. No problem with that in
principle, however, will the correct band settings occur without the
high-current supply in place?  There's no straight through connection around
the filters that I can see.
