Decimal to Binary Calculator For AM88 Programming
This calculator gives the binary equivalent of the AM88 desired output frequency. Enter the desired frequency and the programing for the 12 position DIP switch will appear. The rightmost digit is S1. There are eleven dipswitches to program. The twelfth is not used to program frequency. For frequencies less tham 1024 KHz, fewer than 11 digits will be shown. Since 11 digits are required, You must place zeroes to the LEFT of the displayed programming code in order to arrive at the necessary 11 digit binary number.
Enter Desired Transmitting Frequency kHz



This is the binary equivalent:
As an example if you enter 570 you will get 1000111010 as the programming code. Therefore, since this has only ten digits, you must add a zero on the left as shown: 0100111010. If you had entered 194 KHz you would get 11000010. In this case place three zeroes to the left, as shown in red, to get an eleven digit number as shown: 00011000010.
This calculator may be used for the MPX96 by dropping the decimal point in the desired input frequency and entering it as a three or four digit number between 760 and 1079. The output binary number will be nine digits for frequencies less than 102.4 MHz (entered as 1024). For frequencies less than 102.4 MHz add a leading zero to the binary result. REMEMBER THAT THE NUMBER WILL APPEAR IN REVERSE ORDER IN THIS CASE. ALSO, THE LEAST SIGNIFICANT DIGIT REPRESENTS THE PRESENCE OF THE JUMPER (0),OR ABSENCE OF THE JUMPER (1). It is probably more convienient to refer to the MPX96 Programming chart chart elsewhere on this website.
