What's inside the Retekess TR110 multi-band radio (similar to HRD747 and RF760 models)? Let's take a tour of the mainboard component side only. I've added two diodes for static protection. All other wires and parts are original. The radio functions across all bands. Surprisingly, these are the only components for a modern DSP radio. The ferrite rod antenna contains the only coil in the circuit, while the speaker has one coil inside it. There's no oscillator coil, no IF coil, and no ceramic filters—everything is managed by the software of a small DSP chip.
