[Dxbase] RADIO2 not working

Fri Jul 29 04:32:00 EDT 2011

 I just connected Yaesu FT5K as "Radio2" via COM2 to DXB2007. It took me a
while before I discovered that it does not operate ONLY as Radio2. When
defined it as Radio1 instead of my old Icom- everything became fine, but now
my IC746 does not operate as RADIO2. FT5K still connected to the same COM2
and IC746 is still on COM1.
 Most strange: in order to activate RADIO2 I'm pushing the DXB's virtual
button "activate Radio2", but ANY operation (QSY'ing, for example),
"releases" the button and the command performed by Radio1. 
 Cancelling Radio1 (in Tools section) leaving defined only Radio2 leads to
the same behavior. In other words nothing works for me as Radio2, stand
alone or in conjunction with Radio1.
 Will appreciate any comments.
