Ken,
Yes, and no, I don't believe NaP3 does logging internally, but adding
LP-Bridge to provide virtual serial ports (which emulate the K3 to the
application) can allow loggers, CW Skimmer, etc. to connect through a
single physical serial port (NaP3 would also connect through
LP-Bridge). No
Ed,
The I/Q outputs are baseband audio - just as would be the case with the
output of LP-Pan, or a Sofrrock receiver, or most any SDR receiver. The
serial (or USB) port is only used when rig control is introduced in
addition to the panadapter function.
