The Radioddity QR20 is an ultra-portable full-frequency full-mode SDR radio with a reception from 100kHz to 2GHz and transmit from 160m to 70cm. The operation modes include SSB, CW, AM, FM, RTTY and digital modes. It includes multiple advanced functions and features as an SRD radio station.

The QR20 is designed with both USB and DC interface power supply modes.
The display adopts high-brightness and high-resolution liquid crystal display with adjusted backlight brightness, which can be clearly displayed outdoors. The panel is designed with full keyboard, which is convenient for various operations. The keyboard is with backlight to help operate this radio in a dark environment. The QR20 has a built-in Bluetooth module, a USB cable integrated sound card and a serial port. You can easily control the radio with a single USB cable.

The QR20 has a lot of advanced features that are only available in large base stations. This gear has dual VFO mode, different frequency operation function, intermediate frequency offset adjustment,receiving frequency fine-tuning, intermediate frequency noise suppression, AGC speed selection, RF gain adjustment, squelch control, front attenuator, AM aviation communication reception, AM/FM Broadcast reception, built-in telegraph automatic key, automatic key-point ratio adjustment, built-in CTCSS analog tone, automatic shutdown function (APO), transmission timeout function (TOT); connection with computer and computer-aided control function, copy function, etc.

In addition, the QR20 has several modules to customize more functions.
