[Dxbase] Using Two Icom Radios with DXbase2005

[FKaczmarek at aol.com]

(I looked through the DXbase archives prior to posting this question, but 
didn't find this issue previously addressed) 

Background:  I'm currently using DXbase 2005 after upgrading from previous 
versions over the years.  My original configuration was a Yaesu FT-1000MP (Radio 
1) connected to the computer via Com 1.  The second radio (Radio 2) was an 
Icom IC-756Pro2 connected via a CT-17 level converter to Com 5.  I was able to 
select either radio through DXbase with no problems.  Everything worked as 
expected.

I'm now using an Icom IC-7800 (Radio 1) connected to Com 5 via the CT-17 
level converter (it works fine).  I would like to use the 756Pro2 as Radio 2.  
Since the addresses are different for each radio, I thought I could simply plug 
the Pro2 into one of the unused ports on the CT-17 and make the appropriate 
radio selection in the "User Options/Radio 2" tab in DXbase.  However, when I do 
this I get the following response after I check the "Connect HF Radio 2 Serial 
Interface" box:

"Unable to open <HF Radio 2> comport.  This feature will be turned off"


I must be missing something, but I'm not sure what it is.  Also, Com 5 IS NOT 
derived from a USB-Serial port adaptor.  It is a "real" serial port on a PCI 
I/O board.
