The best GMRS base station in 2023 is the RT97S repeater. It has been upgraded on the basis of RT97. Not only can it relay signals, but it can also act as a separate radio to communicate directly with mobile radio or two way radio.
In today's article, we will introduce the RT97S repeater from four aspects: the functions of RT97S, the unique features of RT97S, the DB-9 connector of RT97S and how to connect to solar energy. Let's take a look.
The RT97S is a 10-watt GMRS duplexer with 16 channel capabilities, 50 CTCSS and 210 DCS privacy codes. The bundle of RT97S repeater includes program cable, power cable and car charging cable. The programming software and accessories of RT97S and RT97 are the same. The RT97S casing adopts a direct amplifier casing. Dimensions are 280×210×75mm. The size of RT97S is slightly larger than RT97.
RT97S repeater has a dedicated microphone. The connected microphone can act as a two-way radio and can communicate with other connected mobile radios or walkie talkies when relaying signals.
The RT97S has one more DB-9 connector for adding an external controller for connection purposes, mainly for ham use.
The DB-9 female connector allows multiple RT97S to be interconnected by connecting an additional component.
Connecting an interface board developed by our friend Scott makes it easy to set up date and time, weather advisories as well as repeater ID and zello. If this option is selected, content will be played over two-way radio waves and zello. Smartphones can communicate with two-way radios using the zello app. Therefore, connecting them together can provide greater range in areas where mobile phones cannot work.
RT97S can be connected to solar energy, which may solve our power supply problem. The operating voltage of RT97s repeater is 12-24V, and solar cells are usually 12V, so we use 12V as the standard. Standby current is 80-100mA. If you choose a 12V 350Ah battery, it can easily meet the needs of a whole day.
