[PVRCNC] Help for Prospective PVRC/NC'er

[Guy Olinger K2AV]

You can put it all on one com port in N1MM.  See
http://n1mm.hamdocs.com/tiki-index.php?page=Serial%2C+Parallel+and+Sound+Card+Interfacing&structure=N1MM+Logger+Documentation#Everything_on_one_COM_port


I seem to recall that there was something about if you do that, that you
can't interrupt a program send before it ends.  I can't find a reference
about that.

The problem with not using winkey is the CW can get choppy on a slower
and/or single core  PC.  Fast quad core PC will never have a problem.  Chop
comes when Windows pays attention to things other than the N1MM program.
 Also Microham boxes take a USB port, include winkey, and break out PTT, CW
and AUX to the transmitter.
