[Kenwood] FW: TS930 8.83Mhz 2nd IF component axcess point

I own a TS940, TS440 & TS930.  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.
  I am having difficulty in knowing where to tap off.  Can anyone help me (I will pay for the solution if need be) where to tap off the 8.83Mhz.  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.  Thank you Terry  Clinard  WA8OPR
