Narrative:

While receiving radar advisories en route from ZFW on flight from hou to ftw, was advised to contact ftw approach for descent into ftw, call made approximately 41 mi from dfw which is 11 mi from TCA. Copilot was handling communication while I was talking to FBO on unicom listening to ftw ATIS. Controller had radar contact and transponder squawk and told us to 'stay clear of TCA. Remain VFR.' I heard him to say 'clear into TCA remain VFR' flew into TCA without clearance due to miscom. I asked copilot if we were cleared in before entering and she said 'no, I told you we weren't.' apparently, I was so used to the standard 'cleared into the TCA' response from the controller that I assumed on hearing the word 'clear,' that it meant proceed as usual. Shouldn't have been listening to ATIS and talking on unicom that close in. Solution is to listen up, always.
