         It's not that simple because Orion's firmware
expects the old 500 and 250 slots to use 9.000750
MHz center frequency instead of the 9.001500 MHz
the first bank filters use.  The filters would
not be centered unless there were an internal
firmware change, and I doubt Ten-Tec would want
to do that since then the 500 and 250 slots would
not be IF centered.  Good idea but the different
IF frequencies for the first versus second filter
banks would not allow it.  Were it not for that,
it would be easy for Inrad to do what you said.
