In attempting to make a list of ham equipment I have owned in the past, I recalled with fondness a surplus cavity bandpass filter I used with OSCAR 10.  At the time, in the 1980s, these were cheap and quite popular with satellite users.  I was living in downtown New Orleans, and the filter, which was mounted at the antenna next to the mast-mounted preamp, totally eliminated my problems with birdies and local cross-mod.

Does anyone recall this filter and perhaps have a photo or info?
