求KG105V/U的编程计算方法望赐教。谢谢！！

A number of parameters need to be worked out;

The 12MHz TCXO is divided by 16 (IC101) to provide a 750KHz Reference Frequency. This reference frequency is sampled and divided by the 'Reference Division Rate' to determine the channel spacings.

Reference Division Rate - 750KHz/12.5KHz = 60 = C30 in reversed Hex as used by the Key (see TX(R) & RX(R) in the table below).

Reference Division Rate - 750KHz/10KHz = 75 = B40 in reversed Hex as used by the Key (see TX(R) & RX(R) in the table below).

Each Address code ALWAYS starts with F i.e. F* F* F* so that for the reference division rate for 12.5KHz C30 works out to be FC F3 F0.

D = Basic Division Rate = Frequency of operation / 12.5

d = Prescaler Division Rate fixed at 64

N = Number of Complete Divisions

R = Remainder of the Basic Division Rate

'N' & 'A' are calculated using the following equation; D = ( N x d ) + A / works out to the following in the example below
11.602 = (0.181 x 64) + 0.018

A TX frequency of 145.025MHz = 145.025/12.5 = 11.602 = D then divided by d (fixed at 64)

11.602/64 = 0.18128125 = 0.181 Number of complete divisions = N = 181 converted into Hex and reversed = 5B0 (see TX(N) in the table below).

0.181x64 = 11.584-11.602 = 0.018 = A = Remainder of the basic division rate

18 converted into Hex and reversed = 21 (see TX(A) in the table below).

Receive is similar BUT 21.6MHz has to be taken off the RX frequency

A RX frequency of 145.625MHz = 145.625-21.6/12.5 = 9.922/64 = 0.15503125

0.155 Number of complete divisions = N = 155 converted into Hex then reversed B90 (see RX(N) in the table below).

0.155x64 = 9.92-9.922 = 0.002 = A = Remainder of the basic division rate

2 converted into Hex and reversed = 20 (see RX(A) in the table below).

这种机器本来就有专用软件的嘛，那用这么复杂。

可借此学习EPROM的编程计算方法。

您好！请问这软件写频，是使用写频器还是用本机直接写到EPROM里的呢？
能否介绍一下写频经验？如有这软件的使用说明可否发一份给我？谢谢您！
