I am running an RX ensemble II with HDSDR and a Behringer UMC204(192 KHz) usb sound card on a windows 10 box.
I have a TX/RX switch to use this with an Icom 718 transmitter ( not always powered on)
Quite often the audio output will either gradually fade out or be killed after a small electrical or noise glitch.
The waterfall display does not change.
Toggling the mode in HDSDR from LSB to FM and then back to LSB always fixes it.
Any suggestions?
