Narrative:

I was receiving a line check on the medium large transport from a company line check airman. The last leg of the chkride was from ind to clt. We departed on time and everything was normal. Shortly after departure we lost the #1 communication radio. No other abnormalities were noted and we continued our flight. We were cleared via the shine 3 arrival to clt. We reported the loss of #1 communication radio to the company via data link on ACARS. Starting our descent for clt, we were cleared to cross shine at 11000'. Shortly we lost the use of #2 communication radio. All efforts to communication via voice proved futile. We advised the company via data link of our situation and continued to clt in accordance with the far's; i.e., we squawked 7600 and continued as filed. On final in clt, we were cleared to land via green light from the tower. A routine landing was made and we were led to the gate by crash crew personnel. The aircraft had several avionics problems throughout the day. It's possible a short or a loose plug was the cause.

Title: MLG HAS RADIO FAILURE INFLT. SQUAWKS 7600 AND CONTINUES TO LNDG WITH GREEN LIGHT.

Narrative: I WAS RECEIVING A LINE CHK ON THE MLG FROM A COMPANY LINE CHK AIRMAN. THE LAST LEG OF THE CHKRIDE WAS FROM IND TO CLT. WE DEPARTED ON TIME AND EVERYTHING WAS NORMAL. SHORTLY AFTER DEP WE LOST THE #1 COM RADIO. NO OTHER ABNORMALITIES WERE NOTED AND WE CONTINUED OUR FLT. WE WERE CLRED VIA THE SHINE 3 ARR TO CLT. WE RPTED THE LOSS OF #1 COM RADIO TO THE COMPANY VIA DATA LINK ON ACARS. STARTING OUR DSNT FOR CLT, WE WERE CLRED TO CROSS SHINE AT 11000'. SHORTLY WE LOST THE USE OF #2 COM RADIO. ALL EFFORTS TO COM VIA VOICE PROVED FUTILE. WE ADVISED THE COMPANY VIA DATA LINK OF OUR SITUATION AND CONTINUED TO CLT IN ACCORDANCE WITH THE FAR'S; I.E., WE SQUAWKED 7600 AND CONTINUED AS FILED. ON FINAL IN CLT, WE WERE CLRED TO LAND VIA GREEN LIGHT FROM THE TWR. A ROUTINE LNDG WAS MADE AND WE WERE LED TO THE GATE BY CRASH CREW PERSONNEL. THE ACFT HAD SEVERAL AVIONICS PROBS THROUGHOUT THE DAY. IT'S POSSIBLE A SHORT OR A LOOSE PLUG WAS THE CAUSE.
