Re: [softrock40] Ensemble TXRX - Background/Image Audio?
Check in the Rep Mixer that you don't have the line input enabled, because you can be hearing the IQ input directly, even with the radio program off. Don't ask how I know that ...

I have just completed the RX section of the Ensemble TXRX which seems to work very well.
The 'problem' I have is that I still get some background audio coming out of the speakers, at a low level, even with no software running!
It can be influenced by running CFGSR and changing the oscillator frequency but will return when put back to the original frequency.
I have tried reversing the audio connections on J2 but this makes no difference. This 'image' type noise also breaks through a little when I run Rocky or SDR Console.
My questions are -
1. Is this a sound card feature?
2. Is this a construction fault?
Your help would be appreciated!
My soundcard details are listed below-
Device: 01 Realtek HD Audio Input
Device: 02 Realtek HD Audio output
