[WT-support] Internal DVK and Windows 7

[Joe Subich, W4TV]

These USB sound cards are relatively inexpensive, provide "three
port" operation and are reported to work properly for DVK with the
original microHAM microKEYER.  I assume they provide analog echo of
the microphone to the line out in order to do that.
