Narrative:
Takeoff was normal. Changed from tower to 119.2 (frequency). Climbed and turned as requested. Do not recall if controllers were changed, but was given a new frequency by departure for ZNY. Neither first officer nor myself understood the frequency. First officer asked again. Controller responded with same speed. Again, neither understood numbers. First officer asked a second time with same result. I then said 'this is the captain of air carrier flight XXXX. We do not understand your numbers.' the controller repeated the numbers, same speed, and stated he did not have time for us and continued same transmission with some instruction for another air carrier flight. Together, myself and the first officer guessed at the frequency 120.85.
