 This plugin is used to produce a wide band FM signal (1 to 250 kHz) with deviation up to 100kHz. The user interface is described [here](https://github.com/f4exb/sdrangel/blob/master/plugins/channeltx/modwfm/readme.md)
 
-## Remote source plugin

-This plugin receives I/Q samples from UDP and copies them to the baseband to be transmitted by the sink output device. It can use the FEC protection sent in the stream to restore lost data blocks. It can use a half-band interpolator (thus in powers of two) to interpolate the stream so that it matches the baseband rate. The user interface is described [here](https://github.com/f4exb/sdrangel/tree/master/plugins/channeltx/remotesource/readme.md)

 ## UDP source plugin
 
 This plugin can be used to receive samples from an application over the network using UDP blocks. For example this can be used to make a connection from GNUradio using its UDP sink block. It can also be used with a UDP source block in a transponder configuration within SDRangel. Also some of the Rx plugins provide an optional UDP output with their audio that can be used for a similar purpose. Note that only the UDP source provides I/Q samples and is therefore suitable for a linear transponder. The user interface is described [here](https://github.com/f4exb/sdrangel/blob/master/plugins/channeltx/udpsink/readme.md)
