	Don,

	You are correct. Uni_Trac 2003, and also Uni_Trac 2000, support the FT-100.

	We, Spectrum International Inc., have also supplied Uni_Trac for use with
the FT-817. 
	I have no personal experience of this but assume it works OK. 
	We have not received any complaints.

	To date, we have not been approached by a FT-857 owner. 
	We have no details of the FT-857 radio's control interface to the outside
world. 
	It may be similar to the FT-100; I don't know.

Just a reminder: Uni_Trac 2000 uses a computer's parallel port
                 Uni_Trac 2003 uses a SERIAL port or a USB port.
	An internal "slot" is NOT required for either of them.

	73s,   de John   G3BVU/W1.
