  1. HAM Radio: Software Defined Radio (SDR) Transceiver (TRX), 16Bit ADC, 2 RX & 2 TX.
  2. Red Pitaya compatible. Firmware of the STEMlab 14, because the TRX-DUO uses 125 Samples, like the STEMlab 14.
  3. You can buy your TRX-DUO from Jan (QRO.cz).
  4. Red Pitaya Charly 25 TRX by Smart Radio Concepts, Edwin, DC9OE.
  5. Heinz, DC5WW, has created a site for the Red Pitaya. He has developed for instance a 50/80Watt PA (max. 32V Input (80W), 24V Input (50W)).
  6. We are developing a TRX-DUO adapter board together with Jan, OK2ZAW, from HamParts.shop, a la the Red Pitaya adapter board of Heinz. But without the audio CODEC board. Audio comes from the PC. If you have a good audio interface (ASIO driver with 64 samples), latency is no problem. With a Low Pass Filter, -60dB at 70 MHz, (a la Gerd, DC6HL) switchable RX/TX and a Preamplifier/Attenuator (a la Jan, OK2ZAW).
  7. (Indian Low Pass Filter 50 MHz (may be not good enough) in front of the RX and in front of the PA. Used by ANAN-SDR. (Thanks Helmut DC6NY for this tipp))
  8. Gerd, DC6HL, has made extensive measurements with the TRX-DUO, published in CQ-NRW.de of Jörg Saure, DD8JM.
