A friend and I are working on his DX-40.  It works beautifully with the 
exception of a hum (sounds more like 60 than 120 cycles to my ear) on 
the carrier when in phone mode whether the mic is connected or not.  We 
have just begun to look at it, but I thought if someone here has had 
experience with the same problem it could possibly save a little time.
