<h1>Simple PTT plugin</h1>

<h2>Introduction</h2>
|

|
|
|

|
|
This plugin controls switchover between a Rx (Device source) and Tx (Device sink). It has no other controls than an adjustable delay from Rx to Tx and back to Rx. Because of its simplicity it can also serve as a model to build other feature plugins.
