 This plugin can be used to watch amateur analog television (ATV). This is black and white and there is no sound carrier. Low refresh rates (FPS) and small number of lines are implemented to support NBTV (Narrow Band TV). The user interface is described [here](https://github.com/f4exb/sdrangel/blob/master/plugins/channelrx/demodatv/readme.md)
 
-## Frequency tracker plugin
+## DATV demod plugin
 
-This plugin can be used to track the center frequency of a carrier. It will try to adjust its center frequency on the carrier center frequency. It is normally used in conjunction with a utility program that monitors the plugin center frequency via reverse API. This utility can then make use of this information to control other plugins or any other purpose. The user interface is described [here](https://github.com/f4exb/sdrangel/blob/master/plugins/channelrx/freqtracker/readme.md)

+This plugin can be used to watch digital amateur analog television (DATV). Accepted standards are DVB-S and DVB-S2. Please note that DVB-S2 does not perform very well and needs a high SNR (>20dB) to work properly. The user interface is described [here](https://github.com/f4exb/sdrangel/blob/master/plugins/channelrx/demoddatv/readme.md)

+## FreeDV demodulator plugin
+
+This plugin can be used to demodulate and decode FreeDV signals (see: https://freedv.org). Not all modes are supported. More information and user interface description can be found [here](https://github.com/f4exb/sdrangel/blob/master/plugins/channelrx/demodfreedv/readme.md)

+## LoRa demod plugin
+
+This plugin can be used to visualize and decode LoRa (Long Range) modulation designed by Semtech. It comes from the original source code and decoding technique has been preserved as is. It has been reported that it works in some cases but there is no formal support for it.

 ## Local sink plugin
 
 This plugin sends I/Q samples from the baseband to a Local Input plugin source in another device set. It is basically the same as the Remote Sink channel plugin but pipes the samples internally instead of sending them over the network. The user interface is described [here](https://github.com/f4exb/sdrangel/tree/master/plugins/channelrx/localsink/readme.md)
 
+## Remote sink plugin
+
+This plugin sends I/Q samples to another SDRangel instance that uses a Remote input sample source plugin to receive the samples. The user interface is described [here](https://github.com/f4exb/sdrangel/tree/master/plugins/channelrx/remotesink/readme.md)

 ## UDP sink plugin
 
 This plugin can be used to send samples to a listening application over the network using UDP blocks. For example this can be used to make a connection to GNUradio using its UDP source block. Optionally the audio at 48kHz sample rate can be returned to this plugin to be incorporated in the audio mix.
