Hello folks,

Just received my LimeSDR-USB today and i already did the first steps on LimeGui, but I am now working on SDR Angel trying to transmit and receive information, the simple antennas I made work well on the 2.1 Ghz band. I am wondering if it is possible with SDR Angel to transmit an audio and ear it at the same time with only one LimeSDR?

Thank you.

I do not know about SDR Angel, but SdrGlut can transmit and hear a signal with one LimeSDR.

Start with the transmit gain at it lowest setting and turn it up until you can hear it.
