Hello Dave,
It's normal, what you hear ! The direct connection to the d-sub connector is 
not recomended as it can damage either the computer or the transceiver. You 
will have to build the interface shown in the N3FJP software, either with 
transistors or with optical coupling ( prefered, no groud loop!). The result 
should be very nice with either interface. GL Dave!
