As the number of DMR registered contacts grows. the hams play DMR radio more and more. We not only can communicate with other hams via simplex, repeaters. With the development of the hotspot, we can communicate more and more hams on the air. Different countries hams can communicate each other on the air well.
When we are standing by one a band, and hear a voice. We want to know who is on the other side of the radio. which country, states, citry, or his callsign,name etc. To meet hams need, more and more dmr radio in the market support to save lots of contacts. When there is a call, the radio can show the caller's information. So we can know the caller clearly when we receive the signal.
RT3S is a dual band dmr radio. It support to save upto 120,000 contacts. Here we need to know that, RT3S supports to record function or import 120,000 contacts. but you only choose one, RT3S can't support them at the same time. That's why there are two different editions. If your radio is RT3S GPS, your radio firmware must be P****, If you radio is non GPS, your radio firmware must be V****. If not, you need to upgrade your RT3S firmware first. more information, please refer to this blog. https://www.ailunce.com/blog/How-to-Upgrade-Retevis-RT3S-Firmware
