The SunSDR2 PRO transceiver was designed for advanced operation on HF and VHF bands, even the most demanding operator will be surprised by its capabilities. Modern hardware along with the ExpertSDR software makes this high-performance SDR transceiver the perfect base station and at the same time perfectly suitable for field operations.
SunSDR2 PRO Main Capabilities
- Independent RX path based on DDC (Direct Down-Conversion) architecture
- Independent TX path based on DUC (Direct Up-Conversion) architecture
- 2 software RXs + SubRX for each of them (4 slices total) + independent widebandĀ Bandscope up to 80 MHz
- A remote controlĀ operation, 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 interfaceĀ for seamless connection with third-party software, the list of software with TCI support
- Professional TX processing moduleĀ provides the most advanced tuning capability for voice operation
- ExtCTRLĀ connector to control external devices with 8 powerful keys with open collector
- ALCĀ connector for external power amplifiers*
- Supports use of VHFĀ transverters**
- An opportunity to use the transceiver as a signal generator viaĀ DAC OUTĀ connector (SMA connector)
- An opportunity to use external filters in the middle of the RF path, usingĀ ADC INĀ andĀ RX OUT (SMA connector)
- MonitoringĀ delayĀ inĀ CWĀ mode is aboutĀ 5-6 ms
- Input for external 10 MHz reference oscillator
- An opportunity to use the transceiver inĀ SO2V mode
- Full duplexĀ or half-duplex modes***
- Antenna switch with 2 HF antenna connectors and separate VHF antenna connector (Mini UHF connectors)
- Internal power-meter for HF and VHF bands and SWR-meter for HF band
- Ethernet LAN interface provides a fast and reliable connection to PC
* ** *** These functions are supported by the transceiver’s hardware, but are notĀ implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.

Totally different level from traditional radio!
Tons of custom settings, super nice filters, waterfall, bandscope, t.eq, etc, etc
Superb Forum & Support!

20W may not sound like a big number, but ample of power for day to day traffic. If you need more output, just put a amplifier behind.
Nice to be able to run 2m with a useful spectrum view in the normally very uncrowded band.
