Hardware improvements in comparison to SunSDR2 PRO:

Improved supply system, which leads to less heating and less power consumption
Active cooling and improved design of the heatsink
Improved TX IMD3 ~37 dB across all HF bands, with 100W output power
Antenna switch supports Predistortion without external devices
HPF for VHF (100 MHz) to eliminate strong out-of-band stations coming from HF
LPF for HF (70 MHz) to eliminate strong out-of-band stations coming from VHF
New VHF LNA chip - PGA103+
New high-performance built-in stereo audio codec 24 bit with 114 dB dynamic range (CS4272)
Firmware based protection algorithms in the PA board
Sturdy DIP-type ExtCtrl connector
New connectors: external tuner control, GND
Improved PCB topology

Main capabilities

Independent RX path based on DDC (Direct Down-Conversion) architecture
Independent TX path based on DUC (Direct Up-Conversion) architecture
Output power: 100W on HF, 80W on 6M and 8W on 2M
2 software RXs + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 80 MHz
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 set up PC
TCI interface for seamless connection with third-party software, the list of software with TCI support
Professional TX processing module provides the most advanced tuning capability for voice operation
ExtCTRL connector to control external devices with 8 powerful keys with open collector
ALC connector for external power amplifiers*
Supports use of VHF transverters**
An opportunity to use the transceiver as a signal generator via DAC OUT connector (SMA connector)
An opportunity to use external filters in the middle of the RF path, using ADC IN and RX OUT (SMA connector)
Monitoring delay in CW mode is about 5-6 ms
Input for external 10 MHz reference oscillator
An opportunity to use the transceiver in SO2V mode
Full duplex 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 is not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.
