[Hallicrafters] SR-2000 draft schematic clarification

[james.liles]

Good morning!
The draft Hallicrafters SR-2000 schematic that I sent to several interested parties includes an added notch filter.  I did not identify it but it extends above the schematic and can be identified by a "Special crystal" component.  The next update to the schematic will include more detail for clarification.  Kindest regards Jim K9AXN
