RDF getting stuck on target

[bencodes07]

In some cases, the RDF gets stuck indicating an aircraft is transmitting, which is not the case. This means, every other aircraft calling in afterwards is indicated as 2 aircraft are transmitting.
So the RDF gets stuck on a target even though they are not transmitting anymore.

This is exactly why .RDF REFRESH is introduced as a work-around. It's a complicated issue involving both TrackAudio itself and the WS SDK.

Maybe it would be an option to just "forget" all transmissions older than some time? Maybe stop displaying transmissions longer than 15 seconds?
Then that problem would solve itself after a short period of time and without the user having to intervene.
