Thanks Tim, however that is not what is displayed on screen when executing the script. It says,

invertptt=1                                                            │
              ; Invert PTT 0 = ground to transmit, 1 = open to transmit  
              ; This is the collector lead of the 2n4401 on the modified
              ; usb sound fob

I still think something is backwards either in the script's logic, the comment lines, or the way the y/n question is worded.  When you answer (YES) to the question "Should PTT be grounded to transmit?", it writes invertptt=1 (open to transmit)

apt_rpt assumes high true as is typical in boolean logic. Therefore low true is inverted.
