        Jupiter is not included in the Expanded Test Reports so I cannot
read the 1 kHz data.  There are some graphs for Pegasus included but I
do not see swept BDR and IMD graphs.  I believe the Sub RX in Orion is
roughly similar to both Pegasus and Jupiter, so here is the data for
Orion's Sub RX compared to the Main RX, to give you an idea:

1 kHz spacing, 500 Hz BW, Preamp on (cannot turn off Sub RX preamp):

Orion   BDR             IMD
Main RX 118             91
Sub RX  64              51

        These are from the graphs on pages 20 & 21 of the Orion ETR here:
