[Elecraft] Interfaces

[Edward R. Cole]

I am glad that I started soundcard programs way back before 
commercial interfaces were born.  It is so simple to make.  I bought 
two 600-ohm pc board 1:1 audio transformers from RS and one 2n3904, 
some resistors and caps.  That was to set up my FT-847 on psk-31.  I 
then used the interface to run the WSJT suite of programs.

When it came time to interface my K3, it was way more simple: connect 
line-in and line out audio with standard computer cables and connect 
a RS-232 patch cable with sub-D 9-pin connectors.  Of course I have a 
computer with a RS-232 serial port and run winXP.  I guess it you are 
using a brand new win7 quad-core computer with only USB ports it 
might be more difficult.  You would have to get a USB/RS-232 cable.

I have more problems with finding the dialog boxes in the computer to 
adjust audio in/out levels.
