It's all about the Software

Hello,
I may be making a mistake.
The filter bandwidth is displayed at odd setting for example 2,5khz with 2,488 Hz.at even setting for example 5khz is also displayed 5 khz. Is this a bug or am I making a mistake in the settings?

Why are you only at 2.4kHz bandwidth on W-FM (WIDE FM)?
The default filters start at 8kHz in SDRC for both N-FM and W-FM

2.4kHz bandwidth on FM will sound terrible!

Hello Kriss,
this is not about the modulation type but about the display. The picture was only meant as an example, the faulty display in HZ also occurs with NFM or BC-FM if the bandwidth is not set to an even number like 5Khz or 10 Khz.
Please try and change the filter bandwidth.

Georg,

Not sure what you are running, since your DSP panel looks NOTHING like mine.
Are you running the latest software?
Are you running SDRC with a 'real' radio via Omnirig?
You have more info than mine!
This is where the WHOLE screen shot attached helps with the back n forth posts trying to
obtain good data, versus the chopped down frequency window of the DSP panel.

Hi George

Sorry to say, I have no idea what you are trying to describe? A full screenshot would help, instead of the cropped one, so that we can see your selected filter setting in the RX DSP panel?

I've just tried setting up some odd, even and random filters in NFM and WFM and all seems to behave totally predictably.
