Sigh, why can't the answer just be given without the nitpicking?
Yes, when referring to trunking systems, sometimes LTR (standard) is referred to as EF Johnson.
You will also see EDACS referred to as GE sometimes.
You will also see (incorrectly) P25 systems referred to as Motorola (they are not); but this mistake is laid at the feet of the scanner manufacturers who continue to incorrectly associate these two.
