Note: There are basically two styles of 9MHz Ten-Tec filters out there currently: old-style for the Omni, Corsair and Orion 565 rigs and new-style for the Orion II 566, Eagle, RX366 etc. Be aware that the old-style filters (including both 9Mhz and 6.3Mhz i.f.) are beginning to show their age and a significant percentage show passband skew and low output. Any old-style Ten-Tec filter should be tested before purchasing - caveat emptor.
