[Elecraft] KIO 2 Not operating

[Alejandro Fernandez - EA4BFK]

Wow !!!

Don, you are great my friend.

Problem solved in less than 1 minute, from question to resolution.

Looks like I changed the sidetone setup by mistake.


Many thanks

PS. I've to start with my KAT100 kit, some others like XV-144 are already in 
the box. Some work for the future
