PC Software & Smartphone APP Control
Want to wirelessly operate your radio? In addition to normal PC software, the QR20 can be easily controlled by custom phone APP through Bluetooth. Android & iOS available.


Built-in Auto Antenna Tuner
The QR20 is equipped with a 160-6 meters high-speed automatic antenna tuner. Tune your antenna directly so that its impedance matches the transceiver and reduces SWR.
Extra Functions Available
You can customize the QR20 with optional modules that add functions like GPS, digital compass and DMR mode. Note that the modules are not included.
