DR2 is also very simple and very good I/Q HF receiver frequency are limited to the 30 - 35 MHz with built in components. I never didnt measure S/N ration in HF CW receiver 80 dB before it. As demodulator it is far superior to the all other types common used demodulators in practice. This receiver can be used as a second or first IF in receivers after crystal filters which very easy reject unwanted image also. Present of image are not a big disadvantage like in DC direct conversion receivers but something about that later.
It can be realized for the very short time for the one afternoon and it is very cheep. This receiver was discovery for me and I spent a lot of time in testing and listening with it in different circumstances. This is series of three parts, three articles are: Parts 1 very simple receiver DR1 without image rejection receiver very simple but good start with the SDR receiving. Try this in field of mathematical calculation you will realize that is everything much easier but you have to be educated with much sophisticate knowledge to do it. Everyone who try to make DC (direct conversion) receiver knows how hard it is to build receiver with good opposite side band rejection or very sharp clear sound and changeable sharp bandwidth filter.

Did you ever build HF receiver 30 kHz to 70 MHz without any coil and that it work exceptionally? You are thinking that isnt possible probably but answer is that it is possible and answer is here in the articles This project is part of my try to made SDR transceiver for HF HAM bands in connection with PC sound card and PC DSP processing. With great technology progress and PC powers this dream is near to be finally realized. My dream, for the all this years was to make receiver and later transmitter design for HF to 50-70 MHz simple as possible without any real RF parts few coils Xtal filtersOf course all with very good specifications high IIP3 and very big SFDR.

Visite: 3037 Stampa Email The CIAOradio H101 is a portable 0.1–30 MHz. Scavone H101 Historical links: Thanks to Alberto di Bene, I2PHD Claudio Re, I1RFQ Ivan Guerini, IW2KBK. Required Library ExtIO_H101.dll uses RTaudio library RtAudio: a set of realtime audio i/o C++ classes by Gary P. ExtIO_H101 early test using: Copy Extio_H101.dll into the SDR application directory and then select the ExtIO_H101 from the SDR application setup. The ExtIO_H101.dll as been realized to enable the use of many SDR program that uses ExtIO interface with H101 hardware.
