Description

The problem appears when one stops the flow-graph, changes some parameters (e.g. freq.) and starts it again.
As soon as the flow-graph is started, Receiver block will still output some bursts from the past for some time.

Please note that I just assume that this is a problem of Receiver block.
It might be also a problem of any other block(s), such as 'TRX Interface'.
