I'd suggest using the quadrature modulator block to build a better TX side. Iterate on that until your signal looks correct. Then you can focus on the RX. On Wed, Feb 14, 2018 at 3:14 AM samuel verdon wrote: > Hello everybody, > > I am building a FSK receiver to recover data on UHF. The bit rate

Hi Gilad! Thank you for the feedback; happy to hear you've got that sorted out through observation of the buffer fillage. Yeah, we need to get smarter on how to understand and prevent such situations. Kernelshark not being the most intuitive tool here is understandable. I'll have to look into how

Hello everybody, I am building a FSK receiver to recover data on UHF. The bit rate of the data is 9,6kbps sent at 437MHz. I put all the information of the flowgraph. The data sent are a Stream of 0x55 or in binar « 1010 ». the medium between the emitter and the receiver is coax cable. Here is my

Hi Marcus, Thanks for the detailed answer. After a long period, I managed to work on it (in several steps) during the last couple of months. I managed to find the bottleneck using ControlPorts. It showed a couple of blocks that were bottlenecks (based on previous block's output buffers). Interesti
