Re: [Discuss-gnuradio] gr-lte updated to GNU Radio 3.7 API

[Ralph A. Schmid, dk5ras]

Do you have the possibility to upload the file to my server? It is on a
VDSL50 line (50Mbps in, 10 Mbps out), so upload from the university (DFN)
network should be fast enough. Then I could post a link for direct download
(well, only 10 Mbps) and provide the file via bittorrent...

Ralph.
