Narrative:
While briefing passenger prior to departure, I realized I was transmitting on the 121.65 ground frequency at dfw during an evening push. As a result I hampered the movement of traffic for about 2 mins. The transmit light on the radio alerted me to this event prior ot the completion of the passenger briefing. This event did not cause any mishaps,however it was embarrassing. Ps: the transmit light on radios are a good safety feature.
