Hytera BD505



Hytera’s BD505 two-way radio is the compact device that provides a professional communication in easy to operate way.

Rugged and Reliable

BD505 is designed and tested to meet Military Standards 810 C, D, E, F, and G, including temperature shock, vibration, high & low temperature, and humidity. IP54 dust- and water-proof design guarantees reliability in different environments. Based on TDMA technology, the radio can work longer, up to 22 hours in digital mode.


This feature allows the switching of channels to be quick and accurate even in adverse working conditions.


With digital encoding and correction technology, the human voice is transmitted much clearer without background noise, even from a rather far distance. This is a new experience of better audio quality.


BD505 can support both analogue and digital modes on the same hardware. You can switch between two operation modes very easily and it helps you to communicate with analogue radios.


Based on TDMA technology, BD505 in digital mode can work as long as 16 hours @ 1500mAh or 22 hours @2000mAh in 5-5-90 mode.
