A Smartwings Boeing 737-700, registration OK-SWT performing flight QS-1131 from Preveza (Greece) to Prague (Czech Republic), was enroute at FL380 just within Austrian Airspace after being handed over from Budapest Control (Hungary) when the crew detected they could hear the ground stations, but ground stations obviously did not hear them. The crew set the transponder code for loss of communication and continued towards Czechia while trying to identify the problem. About 7 minutes later the crew was able to restore two way comminication just before crossing into Czechia's Airspace and continued for a safe landing in Prague.

Czechia's UZPLN reported in their third quarter 2019 bulletin that the crew attempted to resolve the issue (on the ground only noise was heard when the crew attempted to transmit) while communicating with company dispatch via ACARS in the meantime. Selecting other frequencies did not solve the issue. The microphone plug at the captain's side disconnected. When the crew put the connector back into the correct position, the problem disappeared and two way communication was restored.
