[Elecraft] PSK D and FSK D, request for feature

Thu Oct 2 15:13:46 EDT 2014

I want to Echo Rob's question and wonder if it is possible to implement some 
basic autotune algorithm similar to pressing SPOT button in the following 
situation:
When I call CQ in PSK D and someone comes back to my call slightly off 
frequency, I have to enable RIT and try to manually tune to a signal to get 
it decoded. That is not easy. I would like to see the situation when 
enabling RIT in these two DIGI modes would start autotune algorithm 
automatically.
