It just occurred to me that this doesn't solve an RF user sending one 
simplex to another RF user, but I have enough trouble manually 
formatting one to send to myself with a computer and keyboard, I can't 
imagine doing one with a spin knob and push button.  As long as the 
ItemInMessage came from the -IS, all local RF users could benefit from 
the conversion and transmission.  (They'll all see the message anyway if 
they care to look).
