Immense functionality at a reasonable price
When designing each of our devices, we try to achieve the best balance between price and functionality
Full ExpertSDR2 software support
The ever-growing and improving ExpertSDR2 software is 100% compatible with the SunSDR2 QRP and will continue to support it for many years to come, for free!
External control connector
Connect up to 8 external devices to 8 powerful keys with open collectors, such as PA, external filters, antenna rotation devices etc.
Remote control operation
Using it, you connect PTT and CW key to the E-Coder panel. Microphone and E-Coder are connected to the remotely configured PC
TCI interface
Use it for seamless connection with third-party software, the list of software with TCI support
An external sound card is not required
SunSDR2 QRP does not require an external sound card and audio cables, just connect headphones to the transceiver and listen to the air
16-bit ADC at 122.88 MHz
The QRP SunSDR2 has the best ADC in its price range providing 122 dB BDR
Sampling rates: 48-384 kHz
At the same time, you can use 60 MHz broadband + 2 RX software, each with a SubRX
Special mode for 768kHz or 960kHz sampling rate, only for 1 RX+bandcope at the same time
Supports 4M band only for RX in the second Nyquist zone
Field of application
HAM amateur HF transceiver
Remote operation only for fun and competitions
Spectrum analyzer with wide bandwidth up to 60 MHz
Record IQ files and listen to them later
