Hi Simon,

 

Sorry I can’t seem to find your post, could you please link it in.

 

P.S. thanks for the explanation.

Tom,
Did you get my post to this list on Sunday where I provided a sample command and python file that I used to transmit DVB-T with a HackRF, or did it get lost?

The dvbt-hackrf.py file you used from sdr-examples asks for a port because it is expecting to receive the data to transmit via UDP. The outfile, if I remember correctly, stores the transmitted output. 

My version that I posted on Sunday uses a fifo input file. I found this to perform better on my pc, I got overflow issues with the UDP method.

Simon.

Hi Luis,

 

Could you explain please how exactly you got this going, I tried dvbt-hackrf.py from srd-examples and all it asks for is a port and out file (not sure exactly what is needed there)???.  One of the flow graphs from gr-dvbt, dvbt_tx_demo.grc outputs the .ts to .bin and has a sink for usrp which I changed to osmocom sink for hackrf and got nothing, even tried to tx the generated .bin file via hackrf_transfer and still got nothing.

I do have it working, I did use both sdr-examples and the gr-dvbt and both are working.

 

Craig, maybe you have some missing block?

I could never get it going.
