[Elecraft] K3 data decode for dummies?

[Andrew Moore]

Okay, I've got to ask for help now... I'm a geek and been a computer junkie
since 1980 or so, but for the life of me I can't figure out how to get my K3
to decode data modes.  All these choices: AFSK A at 45 bps, FSK D at 45, PSK
D at 31, DATA A... and I feel like I've tried every permutation of mode,
filter width, VFO tuning, etc.. and still come up with gibberish on the
display.  How do I know if the signal is at 31 or 45 bps; which mode;
etc...  Can someone give me a quick "how to get up and running fast and
easy" tutorial?  I've successfully decoded data via a sound card on the PC
before, but the K3's getting the better of me here.  Just want to try it out
on receive... only do 40m CW here (100%), but since the capability is there,
I'd like to try it out.

Sorry for the newbie Q's
