Using it, you connect PTT and CW-key to the E-Coder panel. Microphone and E-Coder are connected to the remotely set up PC
- TCI interface
Use it for seamless connection with third-party software, the list of software with TCI support
- No need for an external soundcard
The SunSDR2 QRP does not require an external sound card and audio cables, just plug your headphones in the transceiver and listen to the air
- 16-bit ADC at 122.88 MHz
The SunSDR2 QRP has the best ADC in its price range which provides 122 dB BDR
- Sample rates: 48-384 kHz
At the same time, you can use a 60 MHz wide bandscope + 2 software RXs, each has a SubRX
- Special mode for 768 kHz or 960 kHz sample rate, only for 1 RX + bandscope at the same time
- Supports 4M band only for RX in the 2nd Nyquist zone
Application field
- HAM amateur HF transceiver
- Remote operation just for fun and for contests
- Spectrum analyzer with the wide bandscope up to 60MHz
- Record IQ files and listen to them afterward
