The only difference is that the rear mic version does not support 
the up/down controls or the +8V line that are available on the 
front mic jack.  If you were to try to use a "Foster" style mic 
that required power or had up/down buttons they would not work 
with the rear mic cable (when the buttons are supported).

The "advantages" are in the additional features of microKEYER II 
- specifically the USB sound card, dual channel receive for KRX3 
support, Icom transceive output for use with Icom accessories 
(e.g., band switching with a PW-1), native control of a SteppIR 
antenna, or an auxiliary serial port for rotor control.
