Narrative:

Shortly after takeoff from sbn we lost the use of our #1 VHF communication radio. The first officer was very quick to respond to this failure and switched to our #2 VHF communication radio. Radio contact was reestablished with departure control. Departure then cleared us to 8000 ft and asked us to switch to chicago center. Which we did. When we contacted chicago, we advised them that we had lost the use of our #1 VHF radio. Center acknowledged this and then cleared us to 12000 ft and direct crl VOR. About 5 mins after contacting chicago it became apparent that we had lost our #2 VHF communication radio. We immediately placed 7600 in our transponder. The first officer searched for a frequency that would work. After several tries, he found that 124.25 worked. This happened to be dtw approach control. We again established contact and also said that we did not want to change frequencys again for fear of losing contact. Approach then vectored us for the approach. Throughout this situation, we used the lost radio communication procedures outlined in both our company operations manual and the aim. Using the lost communications guidelines seemed to work well and the use of 7600 in our transponder seemed to alert the ground personnel to our situation. Throughout this whole experience our navigation radios seemed to work well and never faltered. We landed in dtw without further event and turned the aircraft over to our maintenance personnel.
