VxU reception
(144 MHz + 45.05 MHz) x 2 – (430 MHz - 49.95 MHz) = 45.05 MHz, 49.95 MHz
(144 MHz + 45.05 MHz) x 4 – (430 MHz - 49.95 MHz) x 2 = 45.05 MHz, 49.95 MHz
UxV reception
(430 MHz - 45.05 MHz) – (144 MHz + 49.95 MHz) x 2 = 45.05 MHz, 49.95 MHz
(430 MHz - 45.05 MHz) x 2 – (144 MHz + 49.95 MHz) x 4 = 45.05 MHz, 49.95 MHz
