SunSDR2 transceiver - is an up-to-date system of the amateur radio communication in the HF and VHF frequency bands with the digital signal processing. This device is designed to work with the PC via Ethernet (LAN) or via WiFi. Receive path is based on the direct conversion principle, transmission path – over the direct synthesis principle.
Main capabilities
* 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.

Both diagrams can be used for creating two working places with a single SunSDR2 transceiver.
Connecting to SunSDR2 of external PA, fan and relay
In the document, you can find information about how to connect to external PA. Described the connection to transceiver a fan and relay to control the external BPF, antenna switch, etc.
The schematic diagram for connection VL-1000(Yaesu) and SunSDR2
This schematic diagram provides you to create a special control cable by your own hands. With this cable, you can connect the SunSDR2 transceiver to the VL-1000 power amplifier from Yaesu and control bands switching and PTT mode.
Also, you can use this schematic diagram for building additional cables for control PA, antenna switches etc.
