Weak signal modes

Since my 2013 stroke my voice has been poor, so I have made more use of digital modes to save my voice and help others! On 630m I still use WSPR, but on most bands I use FT8. WSPR works with very weak signals but transmissions take 2 minutes. FT8 is much faster but less sensitive. In both cases they work with signals much lower than CW. They are not chatting modes. All the software needed is free.
