True,
The term has come to mean the customer's radio operational information contained inside the product. Up to and including APX stuff and beyond. The X is probably the last to use a physical code plug, save the Midland ST1 series.
Even though it's Moto term, in the world of CCRs and other programmable radios, it sticks.
A real GE or Johnson guy would never use the terms "PL" or "DPL" for CTCSS or DCS but pretty much everyone eles does....lol
