Rx- mute for transceiver / sdr compo

  • I've something similar. But I put a poti in between so I can reduce the level during my transmit and rise it up when tunig in (I'm using an analog non transceive transmitter). The mute level can be set. The hardware solution was chosen because SDR Console actual is not able to mute audio if not using a limeSDR or so. (V 3.0.12). And I want to use an analog receiver in future anyway.

  • Yes I know. But unfortunately not in receive only mode by using a RTL stick. When using a transceiver (FT-100 in my case) SDR console mutes audio to zero. But not to a certain volume. So I prefer my hardware solution. Like in AO10/13 times.

    I think SDR Console can mute the RX if it detects a strong signal, but not in your case - I will mention this to Simon. However, a practical solution is to use an relay driven by your PTT to put a resistor in series with your loudspeaker or headphones.
