Transceiver with direct digitization
and direct signal synthesis
The SunSDR2 PRO transceiver is designed for advanced use in HF and VHF bands. Even the most experienced operator will be surprised by its capabilities. The modern hardware in a small physical size makes this high-performance SDR transceiver the perfect base station while at the same time very portable for field operations.
SunSDR2 PRO has a special connector for controlling the external devices. It allows connecting to it practically any power amplifiers, rotators, narrow band pass filters, etc. With a help of this capability your place can become a professional studio for work in the air.
The SunSDR2 PRO is perfect for contesting. Its powerful and flexible software lets you create custom designed station setups for many different types of contest efforts.
* Full duplex mode is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.
** ALC functionality is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the future ExpertSDR2 software releases.
The ExpertSDR2 works with Windows 7-10 and Linux Ubuntu/Kubuntu.

This guide describes how to setup ExpertSDR2 for use with one or two CW Skimmers.
Both diagrams can be used for creating two working places with a single SunSDR2 PRO transceiver.
In this document, you can find information about how to connect the SunSDR2 PRO to an external PA, fan, or relay to control the external BPF, antenna switch, etc.
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.
Warning! Software for each device is different! Double-check your device before downloading!
