Narrative:

After a long delay on the ground for IFR release, PNF (captain) decided to depart VFR and pick up clearance airborne. I (PF) agreed and briefly consulted class B local chart. After setting up radial identing class B airspace we asked for and received VFR departure. Once airborne and receiving handoff from tower PNF checked in with departure wherein departure said to call back in 10 mins. At this point I verified that we were still inside defining radial to remain clear of class B airspace. At that point I realized that #1 and #2 navigation heads were tuned to the wrong frequency. Being rather familiar with the local airspace I made an immediate northbound turn to stay clear to the east as well as stopping the climb until visually (by way of landmarks) I was clear to climb VFR. I am relatively certain I did not enter class B at anytime and neither departure nor ZLA controller questioned that we picked up clearance mins later and never questioned the VFR departure. Lesson learned, if there is a last min change in procedure for a departure, make certain you set up the aircraft (tune/identify radios, consult chart more thoroughly) before requesting takeoff clearance. If there are airspeed conditions make sure you remain situationally aware at all times.

Title: A CARJ CREW, WHILE ATTEMPTING TO PROCURE AN IFR CLRNC AFTER DEPARTING MYF VFR, VIOLATED CLASS B AIRSPACE.

Narrative: AFTER A LONG DELAY ON THE GND FOR IFR RELEASE, PNF (CAPT) DECIDED TO DEPART VFR AND PICK UP CLRNC AIRBORNE. I (PF) AGREED AND BRIEFLY CONSULTED CLASS B LCL CHART. AFTER SETTING UP RADIAL IDENTING CLASS B AIRSPACE WE ASKED FOR AND RECEIVED VFR DEP. ONCE AIRBORNE AND RECEIVING HDOF FROM TWR PNF CHKED IN WITH DEP WHEREIN DEP SAID TO CALL BACK IN 10 MINS. AT THIS POINT I VERIFIED THAT WE WERE STILL INSIDE DEFINING RADIAL TO REMAIN CLR OF CLASS B AIRSPACE. AT THAT POINT I REALIZED THAT #1 AND #2 NAV HEADS WERE TUNED TO THE WRONG FREQ. BEING RATHER FAMILIAR WITH THE LCL AIRSPACE I MADE AN IMMEDIATE NBOUND TURN TO STAY CLR TO THE E AS WELL AS STOPPING THE CLB UNTIL VISUALLY (BY WAY OF LANDMARKS) I WAS CLR TO CLB VFR. I AM RELATIVELY CERTAIN I DID NOT ENTER CLASS B AT ANYTIME AND NEITHER DEP NOR ZLA CTLR QUESTIONED THAT WE PICKED UP CLRNC MINS LATER AND NEVER QUESTIONED THE VFR DEP. LESSON LEARNED, IF THERE IS A LAST MIN CHANGE IN PROC FOR A DEP, MAKE CERTAIN YOU SET UP THE ACFT (TUNE/IDENT RADIOS, CONSULT CHART MORE THOROUGHLY) BEFORE REQUESTING TKOF CLRNC. IF THERE ARE AIRSPD CONDITIONS MAKE SURE YOU REMAIN SITUATIONALLY AWARE AT ALL TIMES.
