Re: Using SDR# to drive the SDRplay RSP
Hi Folks, The SDRplay team have put together a very good technical that describes the gain control and AGC concepts very well: http://www.sdrplay.com/docs/SDRplay_AGC_technote_r2p0.pdf Reading through this, it became clear to me that the SDR# plugin allows the user to programme gain settings that ar...

Re: Using SDR# to drive the SDRplay RSP
Hi Captain Nemo, Now set LNA GR T =75 (it is allowed) Raise GR till 63 ===>>> LNA on - MIX on - IF GR 63 GR = 64 ===>>> LNA on - MIX on - IF GR 64 but the audio jump to high level (so the display) until you reach GR 75 ===>>> LNA off (24dB) - MIX on - IF GR 51 (now the audio jump down to expected le...

Hi CaptainNemo and all, let me give you my inputs on these questions: >>>Q: When should I use IF mode greater than zero? Can you tell something about? In Zero IF mode, you will tend to be more vulnerable to any residual DC offsets and possibly flicker noise. You will always have some level of DC off...

Re: SDRplay and SWL usage
Hello all. After some delay(!) I have managed to return to the forum. Re the frequency discrepancy I don't think the 'shift' feature is suitable, as it adds or subtracts a fixed offset at all frequencies, whereas the SDRPlay (in common with all PLL synthesised tuners) has a 'per Hertz' offset. This...
