If you want to learn more about how SDR works, try starting with spreadsheets. Then again, having a programmable signal source on the Arduino isn’t a bad thing and compared to the older version of the board, the new board offers easier breakout for the oscillator signals. That could have led to some interesting possibilities. Plus there are many capable CPU and FPGA boards that have Arduino shield-compatible layouts. That’s a shame because some of the 32-bit Arduinos might be able to do some interesting things with the right hardware. The IQ signals appear on the PC’s soundcard via a microphone or line-in jack, and don’t really route to the Arduino. We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions. There’s also a review video from Elektor about the board in the video, below. There’s also a series of Elektor articles about it. The board is available alone or as part of a kit that includes a book. The Si5351-based board uses that oscillator IC to shift RF signals down to audio frequencies and then makes it available to the PC to do more processing.
If you want an introduction to SDR, Elektor now has an inexpensive RF shield for the Arduino.
Software-defined radio or SDR means you get the RF signal to digital as soon as possible and do everything else in software. We always thought RF electronics would be immune to that, but the last decade or two has proven us wrong. Music synthesizers? RC controllers? Most likely, all microcontroller-based now. A project you might once have done with a 555 now probably has a cheap microcontroller in it. ↳ Licence Free (PMR446/LPD433/SRD860/2.Microcontrollers tend to consume other kinds of electronics.↳ CB & 11m Multi-Mode Modification & Repair.↳ CB & 11m Multi-Mode Radio Equipment Discussion.↳ CB Radio - General Topics and Discussion.↳ Amateur Radio - Digital voice and data.↳ Amateur Radio - General Topics and Discussion.
Elektor sdr receiver software#
↳ Datamodes, SDR & other Radio Software.Also, plug the SDR into your Mac and see if your antenna is picking up interference when the PC is turned on. There's also the Roland Edirol FA-66 Firewire, and M-Audio Profire 610.Ĭan you borrow another soundcard to try in your pc? Might help determine if the noise is soundcard or PC related.
Elektor sdr receiver drivers#
Be aware the drivers can use a lot of PC resources, may struggle with older machines. Popular among these is the E-MU 0202, (a replacement model has come out E-MU 0204, which looks promising). USB audio interfaces have been reported to solve some PC user problems with soundcard SDR. Likewise but with only 96k sampling available, M-Audio Audiophile 2496 and Delta 44 (with external unit). 24 bit 192k record sampling, it's drivers can port audio to multiple applications, has a low noise floor and not expensive. The Asus Xonar D1 is a popular choice for an internal PCI card. A replacement PCI card may not improve things. * The interference may be generated by your PC (ground loops/defective component).

* It could be a windows driver issue, try ASIO drivers if you haven't already done so. A couple of things to consider before replacing your PC soundcard:
