Narrative:

Airport surrounded by thunderstorms during takeoff at clt on runway 18L. After liftoff told to switch to departure controller by tower. I switched to departure and called twice. There was no answer. I checked the frequency and it was correct. I switched to #2 communication radio and heard controller telling us to level at 4000 ft MSL even though we were cleared to 8000 ft on the hornet SID. We leveled at 4000 ft and continued to use the #2 communication radio for the rest of the flight. The #1 communication radio had been written up twice before as intermittent. Both write-ups had been cleared by maintenance. I'm not sure what we could have done differently. It happened at a critical phase of flight when we could least afford a loss of radios, with thunderstorms in the area. We switched to the #2 communication radio quickly because of the previous problems with the #1 communication radio.

Narrative: ARPT SURROUNDED BY TSTMS DURING TKOF AT CLT ON RWY 18L. AFTER LIFTOFF TOLD TO SWITCH TO DEP CTLR BY TWR. I SWITCHED TO DEP AND CALLED TWICE. THERE WAS NO ANSWER. I CHKED THE FREQ AND IT WAS CORRECT. I SWITCHED TO #2 COM RADIO AND HEARD CTLR TELLING US TO LEVEL AT 4000 FT MSL EVEN THOUGH WE WERE CLRED TO 8000 FT ON THE HORNET SID. WE LEVELED AT 4000 FT AND CONTINUED TO USE THE #2 COM RADIO FOR THE REST OF THE FLT. THE #1 COM RADIO HAD BEEN WRITTEN UP TWICE BEFORE AS INTERMITTENT. BOTH WRITE-UPS HAD BEEN CLRED BY MAINT. I'M NOT SURE WHAT WE COULD HAVE DONE DIFFERENTLY. IT HAPPENED AT A CRITICAL PHASE OF FLT WHEN WE COULD LEAST AFFORD A LOSS OF RADIOS, WITH TSTMS IN THE AREA. WE SWITCHED TO THE #2 COM RADIO QUICKLY BECAUSE OF THE PREVIOUS PROBS WITH THE #1 COM RADIO.
