I assume you are talking about JT-65HF on HF bands.
I decode JT-65 signals down to -28. -26 is 100% copy level and get
more marginal at weaker signals. I have decoded as low as -31 but
that is rare. Of course I am talking about JT-65b on 2m-eme where
sky noise is much lower.
For WSJT10 (which is a suite of sw that includes JT-65) I run
monaural audio from line-out from my K3. I run JT65c on 1296 with
this sw which only requires simple audio input thru a
soundcard. Bandwidth on the sw is limited to 2.5 KHz display.
I run MAP-65 on 2m-eme which requires IQ input which comes from a
LP-Pan connected to the K3 1st IF. I get up to 90-KHz panadaptor
display. The LP-Pan provides IQ into a M-Audio Delta44 soundcard
which can provide 90-KHz bandwidth.
SDR sw require stereo soundcards with IQ baseband input.

George,
That is great. -24 dB is good for a built in sound card. By the way
what version of JT65 are you using?
Note that your transmit signal level is usually critical for JT65 and
JT9. Also, I always use VOX to key the transmitter.
