Transceiver with direct digitization
and direct signal synthesis
The SunSDR2 PRO transceiver was designed for advanced operation on HF and VHF bands, even the most demanding operator will be surprised by its capabilities. Modern hardware along with the ExpertSDR2 software makes this high-performance SDR transceiver the perfect base station and at the same time perfectly suitable for field operations.
* Full-duplex mode is supported by the transceiver's hardware but is not implemented in the firmware and software yet. This mode will be implemented in future versions of ExpertSDR2 software.
** ALC functionality is supported by the transceiver's hardware but is not implemented in the ExpertSDR2 software. It will be supported in the ExpertSDR2 1.3 software release.

ExpertSDR2 and CW Skimmer
This guide describes how to setup ExpertSDR2 for use with one or two CW Skimmers.
Using the transceiver for SO2V operation with SDC
Both diagrams can be used for creating two working places with a single SunSDR2 PRO transceiver.
Connecting an external PA, fan, relay etc. to the SunSD2 PRO
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.
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.
Warning! Software for each device is different! Double-check your device before downloading!
