The SunSDR2 DX transceiver is the smallest 100W 160M-6M + 2M HF/VHF SDR transceiver in the world, which makes it ideal companion for your future contests and DXpeditions. It is based on a popular well-known SunSDR2 PRO model. On top of all our previous radios functionality the SunSDR2 DX transceiver offers new features, such as compact hardware design, active cooling, improved power supply system and dedicated connector for a native external ATU. The upgraded hardware design coupled with the ExpertSDR2/3 software makes this high-performance SDR transceiver an outright base station for any DXpeditions and home use.

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, i.e. PAs, antenna switches, etc.
