Narrative:

Flying from jean to las. Climbed to 5500 ft to make radio contact. Immensely busy on frequency -- couldn't get word in edgewise. Realizing this, did 180 degrees (but not before busting las class 'B'). Lesson: know exact boundaries of class B. Anticipate congested radio frequency, especially weekend at busy airport (eg, mccarran). Execute alternate plan (eg, 180 degrees) in event of congestion. Confess to ASRS if murphy gets his way!

Title: PLT OF A C210 ENTERED CLASS B AIRSPACE WITHOUT CLRNC DUE TO RADIO FREQ CONGESTION.

Narrative: FLYING FROM JEAN TO LAS. CLBED TO 5500 FT TO MAKE RADIO CONTACT. IMMENSELY BUSY ON FREQ -- COULDN'T GET WORD IN EDGEWISE. REALIZING THIS, DID 180 DEGS (BUT NOT BEFORE BUSTING LAS CLASS 'B'). LESSON: KNOW EXACT BOUNDARIES OF CLASS B. ANTICIPATE CONGESTED RADIO FREQ, ESPECIALLY WEEKEND AT BUSY ARPT (EG, MCCARRAN). EXECUTE ALTERNATE PLAN (EG, 180 DEGS) IN EVENT OF CONGESTION. CONFESS TO ASRS IF MURPHY GETS HIS WAY!
