Narrative:

Loss of contact with ATC. On bucko arrival, first officer switched to 133.65. We heard radio chatter and assumed our xmissions were being blocked. There was a crossing restr at druzz for 15000 ft that we knew we would be unable to comply with if we did not have radio contact soon. Switched back to previous frequency and was told to switch to 133.65. At that time we noticed the frequency we had set in before was 134.65. ATC had to give us a 360 degree turn to make druzz at 15000 ft.
