Re: adjust bandwidth for WFM

In all modes apart from SWFM, audio limiters prevent the audio level from overloading the audio DACs. In SWFM, these are disabled because of the need to decode the RDS and stereo signals (which appear in the demodulated audio path) and so of you have the volume slider set above 50%, you risk audio c...

Re: A FOOLPROOF ANTENNA SWITCH

Once again, I have had to delete posts that I feel are inflammatory or likely to raise personal tensions. It is a great pity because this debate has been interesting and informative and in my view it is more educational when people are not actually all agreeing. Debate and disagreement feeds new kno...

Noise cancellation with SDRuno V1.32

Here is a great example of how Release 1.32 can be used for local noise cancellation: https://youtu.be/2ptiTxU2wMU The user uses a LZ1AQ active loop which is connected to Tuner 1 of RSPduo, and a active whip connected to Tuner 2. The two antennas are placed 5m apart. Note that the Auto mode is NOT d...

Re: RSPduo ExtIO Plugin – v1.1.1 (9th Apr 2019) crashing service

Please reinstall V3.04 of the API and this should correct your problem. We have just realised that the V1.1.1 of the ExtIO plugin still installs V3.03 of the API and this will be incompatible with release 1.32 of SDRuno.

We will fix this ASAP.

Re: Diversity - how does it work?

Hello folks, There is a problem in using the Hi-Z port in that the gain line-up and gain steps are completely different to those of the 50 ohm ports. For diversity to be effective, it is necessary to scale the two paths such that the levels are equal and then they are combined with the appropriate p...

Re: Diversity - how does it work?

Hello Martin Hi Tech_Support, Thank you for your swift response. I hadn't heard of MRC Diversity and unusually the Wikipedia reference has left me only a little wiser. When MRC talks about "channel", what does that refer to in SDRuno terms. Is it the whole captured spectrum or the just the bandwidth...

Re: Diversity - how does it work?

Hello Martin, The type of diversity implemented in SDRuno is called Maximal Ratio Combining Diversity (MRC Diversity). See: https://en.wikipedia.org/wiki/Maximal-ratio_combining With the correct antenna setup, this can give you an improvement in SNR, particularly in a fading environment. What you de...
