[Elecraft] K3 - SR2O

[Chris G3SJJ]

I am trying to set up my K3 for FD here in Eu in 10 days time. I have 
successfully used SR2O in the past with FT1kMPs but so far not with the 
K3. I have a splitter box which takes both Rx audio channels from the 
headphone socket and splits to one headset for main rx and another with 
sub rx. Neither operator should hear the other rx. This works perfectly 
with the FT1kMP but so far I can't get it to work with the K3. Any 
suggestions?
