The SunSDR2 DX transceiver based on the well-known SunSDR2 PRO transceiver and features several hardware improvements. It is a 100W-HF; 80W-6M; 8W-2M transceiver, very compact, has a fan for active cooling and improved supply system, meaning it’s perfectly suited for DXpeditions and contest operators. 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!

The E-Coder PLUS is identical to the E-Coder except that the VFO optical sensor produce 1024 pulses per revolution compared to 200 pulses per revolution for the standard E-Coder EP. This allowed for more precise fine-tuning when using maximum zoom in the spectrum.

Tilman, SM0JZT –
Great value for money radio. Does not look like a normal radio of course, and you have to get used to the “software interface” on a PC.
Fantastic for “remote control”.
Great improvement in RX but also great to have the big termostatical controlled fan on top.
Looking forward to revised software architecture.

Just as my SunsdrPRO 2, a GREAT radio, with a lot of possibilities. Looking forward to use it on my remote location, with the AAT-100.
A whole new way of doing Ham Radio.
Love it.

I have tried several radios such as Flexradio 6600, Elekraft K3, SunSDR2 Pro and more. The SunSDR DX has a definite fun factor and the challenge with additional software applications and Software Defined Connectors app with TCI appeals to my aging brain. CW and SSB operation runs stable and with excellent reports. With 100W output this radio is a bit more flexible in operation and the improvements makes it a great radio.

SunSDR2DX – is this a realy radio?
In the first days of SDR i wouldn´t have an SDR. Because its not a really radio with scales and knobs.
At our contest group i learn to know the advantages of a Panadapter in combination with a “radio”.
Now i am sitting in front of the SUNSDR2 DX, has the overview of a complete HAM-Band, have unbelievable filters, notches, capabilities,
uncountable functions in combination with the computer, have found a few new DXes.
The conclusion is: Its a really radio.
I don´t miss the boxes with scales and knobs……
Cheers,
Thomas DG1PY
Buy it by PileupDX for a good customer service!

At the beginning of February I bought a SunsdrDX. The transaction was easy and quick.
The device is very compact and fits in every chack. The connection to my home network was easy and now I can use the software on my laptop and Surface Windows tablet without any problems.
I use the software ESDR2 or ESDR3 and it works smoothly with both versions, version 3 is an alpha version and is not yet finished, so there is still a lot missing that can be used in V2.
I already had 2 SDR tranceivers, Flex 3000 and Flex 6300. For me, the SunSDR2DX is by far the better tranceiver.
