Here's the listing, in case anyone is having trouble finding it:

Looks like a fairly compact 8-pole filter with a 5 MHz bandwidth, so it 
appears that it could be tuned to eliminate much interference on the 902 
MHz band. The only bad news is that it comes tuned for 896-901 MHz, so it 
*MUST* be re-tuned to be of any use at 902-903 MHz. I wouldn't have a clue 
how to twiddle those 8 controls to change it to a more appropriate bandpass 
range.

73 and Merry Christmas to all
