John : See the 1st picture. RE stand for Radio emittor.  

Me: Ok.

John : There's a wide distance between the signal of RE1 and RE2. In order to let the distance of signal between RE1 and RE2 become narrower,  we use an LC filter to filter out the low frequency between RE1 and RE2.  

Me: In another words,  we need not the low frequency. 

____

John : Correct. This article mention about the difference between Chip A and Chip B. https://johnkamchihau.blogspot.com/2026/07/httpsjohnchihau_01991067873.html?m=1 . You might have a look. 

Me: Ok.

John: See the 2nd picture. If I select Radio Emittor 2, in code, it is,

.

Int RE = 0000; // 0000 is the address of RE2

.

Function Open_Channel (RE) {

Chip B can transmit to or receive from Radio emmiter 2.

}

.

John : Meanwhile,  Chip A is able to receive the signal from both RE1 , RE2 and RE3.  Yet, Chip A isn't able to transmit any signal.

Me: Correct.
