[R-390] CU-872A/U RX multicoupler

[Chris Kepus]

Do any of you have one of these that is in active duty?    I'm curious about
its performance, etc.  
Since Goggle didn't turn up anything in the way of conversations about this
unit, it may be that the going price of 6922's caused these to be
sacrificed.
Many of you frequent the same forums and lists so please excuse the
multi-posts.  I am casting a wide net hoping to catch a bonafide user to
talk with.
Thanks es 73,
Chris
