Re: [Elecraft] K3: PSK 31 What do I need?

Absolutely nothing.  You can work PSK31 with just the basic K3 either directly 
with 
your CW paddles using data mode PSK-D, or with your favorite software with a 
couple 
audio cables between the K3 and the computer soundcard.  You can set up PTT 
using 
the same K3 RS232 connection to the computer.

BTW...if you are going to use you computer for PSK...you need to have the K3 
data 
mode set to DATA-A and make sure your MIC SEL menu is set for Line-In.

Everything you need in the radio to run PSK or RTTY is part of the 
basic K3. No extras required. You can even run PSK or RTTY by 
sending with a paddle and letting the K3 decode for you. I have 
worked DXpeditions that way, and a few souls have even worked 
contests that way (I don't recommend it). 

For more serious PSK or RTTY work, you will want to use your 
computer sound card to generate the RTTY or PSK tones and to 
decode the tones. Most guys who use only RTTY use MMTTY, a 
freeware program that works by itself for general QSOs and 
integrates with several contest loggers (Writelog, N1MM) for 
contests. For PSK, the nicest software I know of is DM780, also 
freeware, distributed by the guy who wrote Ham Radio Deluxe, a 
very nice radio control program, also freeware. All of this stuff 
is easy to use and install on your computer.   

To use this software, you will need three cables between your 
computer and the K3. You need a serial cable for radio control, a 
cable from the sound card output to the radio input, and one from 
the radio output to the sound card input. You should also do the 
simple chassis bonding shown in my Power Point.

It's also explained in words in Chapter 8 of
