The FAR circuits 9850 VFO board uses SM parts for the filter - elliptical
not bandpass, but it seems to work fairly well. The inductors aren't right
against each other, but they are pretty close and in the same orientation
(not my idea of a good plan). There is a picture of the arrangement at

I'm seeking information about using 2 or more closely spaced SM
inductors (unshielded - not torid or shielded) in a bandpass circuit.

The application I'm thinking of would use two closely spaced SM
inductors and varicaps to tune both the center frequency and bandpass
and allow simple and repeatable construction without the need to
locate and wind torids or find specialty inductors.

Please - experiences and not pure speculation.

Thanks,
