■Internal Beats Frequency Formula

When you receive a signal on the A-band within the 2 m band;

(A-band receive freq. + 59.85 MHz) x 10 – (2 m band receive freq. on the B-band + 57.6 MHz) x 10 = ±59.85 MHz or ±57.6 MHz 1

(A-band receive freq. + 59.85 MHz) x 3

– (1.25 m band receive freq. on the B-band + 57.6 MHz) x 2 = ±59.85 MHz or ±57.6 MHz 1

(A-band receive freq. + 59.85 MHz) x 8

– (1.25 m band receive freq. on the B-band + 57.6 MHz) x 6 = ±59.85 MHz or ±57.6 MHz 1

(A-band receive freq. + 59.85 MHz) x 4

– (70 cm band receive freq. on the B-band – 57.6 MHz) x 2

= ±59.85 MHz or ±57.6

MHz

(A-band receive freq. + 59.85

MHz) x 6

– (70 cm band receive freq. on the B-band – 57.6 MHz) x 3

= ±59.85 MHz or ±57.6

MHz 1

(A-band receive freq. + 59.85

MHz) x 7

– (70 cm band receive freq. on the B-band – 57.6 MHz) x 4

= ±59.85 MHz or ±57.6

MHz 2

(A-band receive freq. + 59.85

MHz) x 9

– (70 cm band receive freq. on the B-band – 57.6 MHz) x 5

= ±59.85 MHz or ±57.6

MHz

(A-band receive freq. + 59.85

MHz) x 11 – (70 cm band receive freq. on the B-band – 57.6 MHz) x 6 = ±59.85 MHz or ±57.6 MHz 1

within the 1.25 m band;
