Notes:
1] Frequency is recorded with 3 leading digits before the "M" and 4 significant digits after the "M" [including zeroes]. Frequencies that have significant digits
after the "M" that exceed the 4 digits. The remaining digits will be truncated from the CTS part number, but the factory will calibrate to the full frequency
desired. Examples below; P/N Frequency = Actual Frequency
13M5537 = 13.553750MHz
14M3181 = 14.318180MHz
16M6666 = 16.666670MHz
28M6363 = 28.636360MHz
