 ## Known Limitations
 
 - RTTY Modes **NOT** supported: 5bit baudot, 1.5 bit stop
-- SSDV is not supported
 - Decoding will stop if decimation setting is too low or too high. It was tested to work with stream around 40kHz bandwidth.

 - Connecting from browser is not very reliable yet, sometimes you need to refresh and wait.
