<A band>

 

<B band>

 

 

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
