Narrative:

Radio contact lost en route to atl. At first, approach control was being received intermittently, then lost all together. Squawked 7700, then 7600, and continued to the filed fix atl VOR. I switched to the #2 radio and started to hear atl approach controller again. I attempted to make a radio transmission to approach, but lost contact again. At that point, the captain attempted to contact atl approach with success. The captain xferred control of the aircraft to me, and the flight landed without any further problems. We were deiced in mem, and it was raining at the time (large transport fzdw). I feel water and glycol entered my radio communication panel and was shorting out my xmissions as well as interfering with atl's attempt to contact us. An atlanta line mechanic did meet the aircraft and did find moisture in the communication panel.
