the biggest problem would be finding space for an additional connector
inside the jornada. after that - just wire the jack, so that the
microphone is connected when there is no jack inside. the level attenuator
and a DC blocking capacitor can be external to the jornada in the cable
(inside some heat-shrink tubing).

i'm not sure if the jornada can handle PSK31, due to no floating point
capabilities, however RTTY and SSTV should be ok
