Looking at earlier µBITX schematics, the lowpass filters on the V3 µBITX were switched by 'KT1' through 'KT3'.  Maybe the code reference is vestigial.

Hey Mark,

   K1's the transmit/receive relay - activated by the transmit signal.  I suspect that's how 'KT' was originally labeled.  It's in the lower left of the V6 schematic.
