BFDX BF-TD501 DMR digital walkie talkie
BF-TD501 is a professional digital two way radio-TDMA, supporting digital and analog
2 working modes.According to standard DMR protocol,TDMA dual slots,dynamic
encryption,with 4FSK modulation,AMBE+2™ vocoder,this make BF-TD501 as a best
radio for you to migration from analog to digital.
Wroking in digital and analog 2 working modes
It supports digital and analog 2 working modes,meeting different communication demands.
Dual slots
Dual slots TDMA-Time division multiple access,greatly increase the communication capacity.
Voice encryption
Encryptioned code can be set via software,which can be used to scramble and descramble
voice call on encryptioned channels.
Individual call
Except the pointed 2 person can talk with each other,noboly elase can hear,which can well
