Crystals & Filters




Mechanical Filters

450 KHz Collins Mechanical Filters Used, checked OK

526 9901 010 & 526 9902 010 -- LSB & USB set, 2.2 KHz Bandwidth. $200 for the pair



Crystal Filters

10.7 MHz, 13 KHz Bandwidth Crystal filters. I believe these are pulls from some Motorola radio. Two carry what I think is a Mot part no. 532-0003-01.

They are all the same size & footprint. About 2+" long by 1" wide by 3/4" high. On the bottom, there are a pair of (4-40?) studs on diagonally opposite corners, in & out pins on the other pair of corners. A ground pin sits in the middle of one side. Assorted mfgrs. used $5 ea
