Hi, I'm trying to create a flowgraph with a TCP Source block and a Pluto sink to tx the packet.
From the Freq. Sink seem to transmit but if I try to received the modulated signal with another Pluto it is absent.
Currently, I'm running the flowgraph in Ubuntu 19.04 and GNU Radio ver. 126.96.36.199.
You are at different LO frequencies and I would recommend using slow-attack on RX.
I updated the flow wiht your suggestion but nothing has changed
You will need to dig into the receiver code then to determine why you are not able to correctly recover a signal.
use low pass filter at receiver, that might help.
