[Orion] FS: Inrad #759 (400 Hz at 9000.75 kHz)

[Bill Tippett]

	This filter is a plug-in for Argosy I and II, Omni V and VI,
Omni B and C, Orion and Triton IV.  It can be wired-in for the
Argonaut 506, 509 and 515.  See following compatibility chart:

455 kHz 6 dB bandwidth and 2.1:1 6/60 dB Shape Factor is
a direct substitute for the Ten-Tec #217 500 Hz filter.  See
Inrad's Performance Curve here:

Inrad's price is $115 plus $6 S&H (Priority).  Ten-Tec #217 is
$109 plus $6.75 (UPS surface).  First $85 check or money
order gets it shipped to USA only via Priority Mail in original
packaging.  This filter works fine but I plan to use Inrad's #352
kit in my Orion and no longer have a use for it.
