On climb out from jax, runway 7, departure complained of poor quality radio transmission. There had been no prior indications of radio trouble. The first officer, who was the PF, was able to communication clearly. We were given a turn to the northwest and a climb to 15000 ft. Shortly thereafter, we realized that we had no communication at all. We maintained heading and altitude while attempting to troubleshoot. Not having any success, we decided to return to jax. We set 7600 in the transponder and proceeded back. Beginning a descent as we approached the airport. For approximately 30 seconds, the #2 radio worked as we approached jax, and during that time, we were able to notify company of our return and establish that jax approach was aware of our situation and got the active approach and a vector to the downwind for runway 7 ILS. Communication was again lost and we proceeded onto the base and then final and an uneventful landing. I called the tower after landing to thank them for their help as well as jax center. Neither indicated any concern about the procedures used. Contract maintenance found both communication radios to be without power. They were able to restore the radios with a generous amount of re-racking and swapping.
