I have the EJ-41U in the Dr-135TP for my K1XVM Igate.  It is running 
in converse mode because it had a habit of locking up in KISS mode 
during bursts of data at random intervals.  I use it with Xastir.

Nice radio, nice little package (even can act as a tracker too), but 
yeah it has shortcomings.

If you have additional questions feel free to ask.. :-)

--Droo, K1XVM
