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.
* ** *** These functions are supported by the transceiver's hardware, but are 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 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 is device-specific! Don't mix software with unsuitable hardware, it may lead to issues that are not covered by warranty!
