[Elecraft] A KX3 Curiosity Question about ACC2 and RXIQ

[Phil Hystad]

On my KX3 the ACC2 and the RXIQ connectors are 2.5 mm rather than a more common 3.5 mm.  So, does anyone know why these are 2.5 mm rather than 3.5 mm.  I understand that they are smaller but looking at the KX3 and how and where they are located I do not see that smaller is required for the design.

Is there a good engineering design reason behind this decision?  I have no complaints but rather lots of curiosity.
