The Expert Electronics' SunSDR2 PRO SDR 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 Expert Electronics' ExpertSDR2 software makes this high-performance SDR transceiver the perfect base station and at the same time perfectly suitable for field operations.
Expert Electronics SunSDR2 PRO SDR transceiver 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 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 like SDC (with its own Skimmer), LogHX, SWISSLOG and RUMlog, more are coming
- 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)
- Small delay in CW mode (about 10 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 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.
You must enable the program on windows10 firewall, otherwise it will disable the communication. After every firmware upgrade, you should do it.
Expert Electronics SunSDR2 PRO SDR transceiver box contains:
- SunSDR2 PRO Transceiver
- LAN-cable 1.8m for connecting to local network
- Power cable 2.0m for connecting to power supply
- Two 6.3mm phono male to 3.5mm phono female adapters to connect a headset to the radio
- Mini UHF (male) to SO239 (UHF/PL female) pigtail adapter with 30 cm RG58 coax.
Does it contain adapters for the mini-UHF to PL259/BNC?
Box contains one pigtail cable (cca 30 cm) that converts MiniUHF to SO239. If you want to use more than one antenna port, you may need to custom-make further similar pigtail cables or patch cables with MiniUHF on the radio end yourself. MiniUHF connectors, H155 coaxial cable and crimping tool are available from the Anico hamshop (check optional products). MiniUHF-SO232 adapters without pigtail cable are also available, however these adapters need to be used with special care (for explanation see video: https://www.youtube.com/watch?v=_w45ICmsCHU&t=493s )

SDR radios have no control panel, therefore manufacturers do not supply a user manual. Our company only sells SDR hardware; operation of these devices requires various software that you can download from the internet. Most of these software products are only available for download in the English language from the websites of manufacturers and third party developers (many of them radio amateurs) either for free or for a fee. Installation, setup and usage of the software require an intermediate level of proficiency in computing and the English language. We do not advise to buy these equipment unless you are in possession of these required skills, and we highly recommend to seek assistance and prior information from other radio hams on internet-based forums and user groups.

About the Sun SDR2 : I am just learning how to use it and it fullfills all my requirements, so far. So my rating is very good as well.
Despite the covid period the package arrived quickly.
This transmitter is really compact but of a formidable efficiency.
One immediately feels the extreme sensitivity and the quality of the audio.
The software interface is nice and powerful.
I do not regret this choice.
Thanks and Rregards
Keep up the good work!!
Tulajdonképpen nem is egy rádió hanem kettő egy tokban, továbbá 160m - 2m ig (HF -> VHF -ig) meg van oldva minden! A rádión rengeteg csatlakozási felület van amivel bármilyen komolyabb versenyzési célokra is lehet a készüléket használni. Ez egyszerűen egy zseniális technika. Vételi és szolgáltatási paraméterei lenyűgözőek.
Feltétlenül érdemes hozzá külsőkezelőt is vásárolni!
