Welcome to SunSdr.eu. We are here to help with your order and to answer any technical questions you might have. Please notice that we ONLY can help you if you bought the radio from us (Pileup Communications , www.sunsdr.eu). If you bought your sunsdr radio or equipment elsewhere you need to contact the dealer you bought it from or directly contact manufacturer at www.eesdr.com .
In our downloads section we also offer the latest firmware and accompanying manual for your sdr transceiver, amplifier or accessory.
