[TenTec] Filter identification

[d.e.warnick at comcast.net]

Has anybody ever come up with a model number for the 48074 filter? It's the standard 2400 Hz filter in the 6.3 MHz IF of the Omni VI.

A bit tougher perhaps. Can anybody identify a 48057? It's a 4-pole filter. That's all I know. It was in a box of spares with an Omni VI that I recently bought. If possible, the IF freq and the bandwidth.

Thanks
