You can if you aren't in an area that requires Mode/C can't you?



Have a look at FAR 91.215, especially paragraph (c): Transponder-on operation:

"While in the airspace as specified in paragraph (b) of this section or in all
controlled airspace, each person operating an aircraft equipped with an operable
ATC transponder maintained in accordance with §91.413 of this part shall operate
the transponder, including Mode C equipment if installed, and shall reply on the
appropriate code or as assigned by ATC."

Although paragraph (b) refers to the airspace where Mode C is required, I read the
"or" in the above sentence to mean: "if you're in controlled airspace (A, B, C, D
or E), and your transponder support Mode C, you must have Mode C turned on."
