How to achieve Retevis RT52 DCDM function?

 

Taking HD1 and RT52 to test this function

1.When turning off the DCDM function

For example:

HD1: TX=RX=462.23500 cc:1, contacts: lee, the time slot: 1
RT52: TX=RX=462.23500 cc:1, contacts: lee, the time slot: 2
RT52 can talk with HD1 each other, the time slot doesn’t work

2.When turning on the DCDM function

HD1: TX=RX=462.23500 cc:1, contacts: lee, the time slot: 1
RT52: TX=RX=462.23500 cc:1, contacts: lee, the time slot: 2
RT52 doesn’t talk with HD1 each other, the time slot will work

if you change the slot time 2 on HD1, RT52 keep the same set
HD1: TX=RX=462.23500 cc:1, contacts: lee, the time slot: 2
RT52: TX=RX=462.23500 cc:1, contacts: lee, the time slot: 2

RT52 can talk with HD1 each other, it also indicates the slot time will work, only same slot, they can communicate with each other
