I am looking for an International Radio #1906 AM filter. This is a 6khz filter centered at 9.001mhz (50 ohm impedence) and is used to improve AM reception in the Drake TR4/TR6 series of radios. INRAD has discontinued and I think they are pretty hard to come by, but I thought I would check here.
Thanks,
