Spitfire starting/take off at Manston 118.45 canal A( trying all, B C D nope), in the air, calling tower no replies ?? i've tried P-51, Mosquito all voice call  & tower reply fine, weird issue in cockpit i hear "my" request but no "voice" reply text onscreen only ?

i did a repair (full & slow one) without success, maybe something corrupted somewhere ?
