-
- No, the actual frequency is the actual minus the i-f (10.8 for
- Bearcat, 10.7 for all other scanners.

- > holder: what's this? Did i misunderstand?
-
- How is the crystal mounted - solder-in, socket? Which size? I
- don't know the specific type names.
-
-
- > tolerance : is that ppm? what's normal for this sort of thing?
-
- Primarily for transmit crystals. How much can the crystal
- frequency vary over a given range of temperature.
-
-
- > load capacity: is that like power capacity? what's normal?
-
- A crystal operates in parallel or series with a small capacitor
- (load capacitance).
-
-
- Now, after all that; get in touch with a company that deals with
- scanners or scanner crystals. They will have all the above info
- on file for the various models. Look for names in a Scanner
- Guide or communications magazine.
