X-Mailer: Unknown (No Version) Hi Lawrence the Winradio 313internal or external receiver contains DSP internally and does not rely on Soundcard so that it can be used for other processes. The internal version can also be ordered with IF out and also external precision oscillator input to ensure accurate tuning. Well worth looking at. I have had no PC interference problems affecting the senitivity etc, and use Argo,Skysweeper and SpectrumLab without problems dave G8SZX Glenfield Leicester IO92jp webpage www.g8szx.mediumwaveradio.org lawrence mayhead wrote: > So that leaves SDR receivers like the Perseus, thanks Johan, but these > are digital, can the AGC be turned off? and another problem if my > computer sound card is tied up processing I/Q signals can it also do > the FFT analysis ? at the same time.
