Congratulations
On behalf of the whole Expert Electronics company, we'd like to thank you for purchasing one of
the best modern SDR transceivers!
The SunSDR2 DX transceiver is the smallest 100W SDR transceiver, which is perfect for
contests and DXpeditions!
1.2
Features
The SunSDR2 DX transceiver based on the well-known SunSDR2 PRO transceiver with several
hardware improvements. It is a 100W-HF; 50W-6M; 8W-2M transceiver, very compact, has
active cooling and improved supply system, meaning it’s perfectly suited for DXpeditions. Also,
we've added a separate connector for an external ATU, thus SunSDR2 DX has all the
functionality you got used to in our radios and even more. Improved hardware along with the
ExpertSDR2 software makes this high-performance SDR transceiver the perfect base station.
The evident choice for a true contester!
