Sometimes a question like this brings many replies from those that do this, coupling a Lite to the IF.
There are probably answers if you search old posts. eg
There is a special version of PSDR that is used for this, I guess it makes it easy.

Hi Ron, there's software to make some SDR receivers track the 590, I
believe you can make a Perseus do this and serve as an (expensive)
panadaptor. I have never seen any means of making the Softrock track
the 590, but would love to be proved wrong. I *THINK* Ian Wade has
some info on making software to track the 590 run with certain SDR's,
but there's definitely videos on You Tube showing this working. The
writer of the software is in the USA. I believe a forum member here
who posts using the user name "Richards" knows about this, we spoke by
e-mail ages ago as it was the one thing that made me wonder whether to
get a 590 with its dual IF's and no IF out port. Good luck, please let
us know how you get along.

I am using a Softrock with my Elecraft K2. I tapped into low-level audio and am using a buffer amplifier to bring the signal out to the back of the K2.
I use the Softrock as both a panadapter and to feed audio to CWSkimmer. I am quite happy with the setup.
Sorry if this doesn't make much sense; I just woke up. If you have questions fire away. Hopefully I will be more awake later :-)

I've talked to one local ham who gave me some ideas - just would like to hear what others are doing as well.

- Hi, Ron,
I have a TS-590S and use a SoftRock RX Ensemble II as a second receiver and panadapter, controlled with the HDSDR and Omni-Rig software:
Thanks to Bob, W7KWS, for the hint on using HDSDR. This software allows tracking of the TS-590S and SoftRock VFOs, as well as many other features.
In my application the SoftRock is connected to Beverage antennas through a homemade preamp and a passive "receiver saver".
The receiver saver I use is a T configuration, using two 22 Ohm resistors in the top of the T, and paralleled silicon switching diodes for the vertical part of the T. One of the diodes is reversed, so signals are clipped at about 0.7 volts. This T is then terminated across another diode pair going into the home-brew preamp for extra protection. Lastly, the same approach is used at the output of the preamp.
Another approach is to use the transmit antenna for both the TS-590S and the SoftRock through a relay switching arrangement, similar to the approach used to connect the SDR-IQ in this paper (see page 3):
On the TS-590S, you could select the RX antenna on the front of the radio. This connects the TS-590S receiver to the RX antenna jack on the rear panel. A Y-phono connector plugged into the TS-590S RX antenna jack allows the SoftRock to be connected in parallel with the TS-590S receiver. The remaining port on the Y connector goes to a relay that switches between the receivers, the TS-590S transmitter, and the transmitting antenna. Do this at your own risk! You do not want to transmit into the receivers!!!
Another possibility is to internally jumper the RX antenna connection in the TS-590S to the TS-590S Receiver board antenna input. This would allow an outboard receiver to be placed in parallel via the RX antenna input and would allow using the transmit antenna via switching through the internal TS-590S relay. Careful, as this may void your warranty.

For those who would like more information on using a SoftRock RX Ensemble II Receiver as a pan-adapter for the TS-590S, refer to this link:
