12.21mhz X 2 = 24.42 mhz, 24.42mhz X 2 =48.84mhz, 48.84 X 3 = 146.52mhz 12.21MHz * 2 = 24.42MHz, 24.42MHz * 2 =48.84MHz, 48.84 * 3 = 146.52MHzWhen talking about a total deviation at the final frequency of 5kHz then consider we arrive at that number (5kHz) the same way we multiplied to arrive at our target frequency of 146.52MHz. 416.7Hz * 2 = 833.4Hz, 833.4Hz * 2 = 1666.8Hz, 1666.8Hz * 3 = 5000.4Hz which rounds to 5kHz
