TRX-DUO
- HAM Radio: Software Defined Radio (SDR) Transceiver (TRX), 16Bit ADC, 2 RX & 2 TX.
- Red Pitaya compatible. Firmware of the STEMlab 14, because the TRX-DUO uses 125 Samples, like the STEMlab 14.
- Wir haben unseren TRX-DUO ueber AliExpress gekauft. Lieferzeit nach Deutschland circa 1 Monat. Zollabwicklung ueber DHL. (Wichtig: Mit Garantie kaufen, bzw. am Anfang intensiv testen)
- Red Pitaya Charly 25 TRX by Smart Radio Concepts, Edwin, DC9OE.
- 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)).
- 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).
- (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))
- Gerd, DC6HL, has made extensive measurements with the TRX-DUO, published in CQ-NRW.de of Jörg Saure, DD8JM.
