My 2 friends just linked their 440 machines together using an Alinco DR-235T at each end for the link. They did find that there is a delay in time in which the decoder takes to decode and release. They are going to fix this by using Audio Delay Modules in the controllers at each end of the link. Also, using a high PL tone should help the decoder decode faster.
