Narrative:

First officer landed runway 18L in tampa. I had not set up the radio for ground frequency (contributing factor). While we taxied clear, I thought I heard (assumed?) tower clear us to taxi to ramp -- they had not. As the aircraft nose crossed the hold short for runway 9-27, first officer tuned in ground frequency. Without even having time to transmit, we received a call from ground clearing us to taxi to the ramp. I have never seen runway 9-27 used, which contributed to my 'casual' taxi mindset. In the future, I will make sure I have ground set up for the first officer, and never cross any runway unless I am sure I have clearance. Supplemental information from acn 585011: I started my normal flow. I immediately raised the flaps, turned off the transponder and radar. When turning off the radar, I noticed that approach control was the backup frequency on radio #1.

Original NASA ASRS Text

Title: A B737 FLT CREW THAT THOUGHT THEY WERE CLRED ACROSS A RWY, ACTUALLY CROSSED WITHOUT A CLRNC.

Narrative: FO LANDED RWY 18L IN TAMPA. I HAD NOT SET UP THE RADIO FOR GND FREQ (CONTRIBUTING FACTOR). WHILE WE TAXIED CLR, I THOUGHT I HEARD (ASSUMED?) TWR CLR US TO TAXI TO RAMP -- THEY HAD NOT. AS THE ACFT NOSE CROSSED THE HOLD SHORT FOR RWY 9-27, FO TUNED IN GND FREQ. WITHOUT EVEN HAVING TIME TO TRANSMIT, WE RECEIVED A CALL FROM GND CLRING US TO TAXI TO THE RAMP. I HAVE NEVER SEEN RWY 9-27 USED, WHICH CONTRIBUTED TO MY 'CASUAL' TAXI MINDSET. IN THE FUTURE, I WILL MAKE SURE I HAVE GND SET UP FOR THE FO, AND NEVER CROSS ANY RWY UNLESS I AM SURE I HAVE CLRNC. SUPPLEMENTAL INFO FROM ACN 585011: I STARTED MY NORMAL FLOW. I IMMEDIATELY RAISED THE FLAPS, TURNED OFF THE XPONDER AND RADAR. WHEN TURNING OFF THE RADAR, I NOTICED THAT APCH CTL WAS THE BACKUP FREQ ON RADIO #1.
