I used to build the APRS Mic-E (MIM) module into
a variety of mics so that APRS could be used with
any radio, just by moving the mic and GPS from radio 
to radio.  But my most practical application was
putting a 9V battery and mic in a tiny box from RS
that looked like a speaker mic so that it could be 
plugged into any HT in the field and allow APRS
position reporting from handhelds...

The one in the middle will plug into any HT.  Note the
PTT button and mic hole near the top and the
MESSAGE switches on the face and the GPS plug
in on the bottom.  A plug-n-go solution for adding
APRS to any HT...

I no longer make them... but someone should....
