Look on the rear apron of the TS-930.
There is an RCA Phono jack labeled IF. That has it already brought out
for use with the Kenwood SM-220 and BS-8. That IS the 8.83Mc IF tapped
already for panadapter purposes.
There is no reason to poke around inside to get what you are looking for.

On the 440 & 940 I use a LP-PAN http://www.telepostinc.com/ panadpater quadrature unit that allows me with a good quality sound card to get a 192Khz full view receive panadpater on my laptop computer. The panadpater input is set for the IF frequency of 8.83Mhz. I recently purchased a 7 million serial number TS930 and have been studying the schematic to understand where a good tap off point would be located on the signal board, to get a reasonably strong 8.83Mhz for the LP-PAN unit. I couple the IF to the LP-PAN with a 33uuf capacitor using RG mini 52 ohm coax.

Nearest I can figure is that I should tap off at either of two spots: On the signal board: tap at anode side of diode D93 OR tap off the anode side at Diode D88. These diodes are either side of XF3.
