The SunSDR2 DX transceiver is based on the well-known SunSDR2 PRO transceiver with several hardware improvements. It is very compact for a 100W format, has active cooling, and an improved supply system, meaning it’s perfectly suited for DXpeditions. Also, it has 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 ExpertSDR2/3 software makes this high-performance SDR transceiver the perfect base station. The evident choice for a true contester!
Hardware improvements in comparison to SunSDR2 PRO:
* ** *** 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.

Using the transceiver for SO2V operation with SDC
Both diagrams can be used for creating two working places with a single SunSDR2 PRO/DX transceiver.
Connecting an external PA, fan, relay, etc. to the SunSD2 PRO/DX
In this document, you can find information about how to connect the SunSDR2 PRO/DX to an external PA, fan, or relay to control the external BPF, antenna switch, etc.
Control cable schematic for external PA VL-1000 (Yaesu)
This schematic allows you to assemble your own control cable for PA VL-1000 by Yaesu. With this cable, you control PA's bands and RX/TX mode. This cable might be used for control of other devices, which works with 4-contact control protocol by Yaesu, e.g. PAs, antenna switches, etc.
