[Elecraft] K3S, P3 and USB Audio

[Don Wilhelm]

Paul,

I don't know whether you can use the USB soundcard provision of the K3S 
while using some other RS-232 port connected to the P3 and through the 
RJ-45 to RS232 'dongle' at the same time.  But my thought is that they 
are separate, the soundcard function is just like any external USB 
soundcard.

I think you *should* be able to do that, but just keep in mind which COM 
port is connected to your USB to RS-232 adapter and which one is the one 
in the K3S.  The USB port FTDI will likely still show up in the computer 
Device Manager.  Note the COM port number and do not use it to connect 
with N1MM.
Do not set the K3S RS-232 menu to USB, set it to 38,400 instead.

You might want to try something more simplistic than N1MM first (like K3 
Utility) to verify that the PC to P3/K3 connection works.

Once you can verify communications with K3 Utility, then try N1MM.

73,
