[TangerineSDR] Field Day 2019 DigitialRF Data

[Engelke, Bill]

Tom:

What error or problem do you get when you try to play back the field day data?  I can get it to work (see screenshot).

Idea:   The Digital RF block in GNURadio looks for a very specific directory structure and the properties file must be in the right place. In this case, I have the directory pointer in the GNUradio block set to /tmp .  Under the /tmp directory is the directory /hdf5.  Directory hdf5 contains the file drf_properties.h5, plus the folder of the time slice to be displayed, in my case 2019—06-22T17-00-00.  Within that directory is the file of the data, in this case rf at 1561226332.000.h5<mailto:rf at 1561226332.000.h5> .

This structure is peculiar to Digital RF, and it also assumes that you have selected data for a particular center frequency (this is not automatic), and have entered the center frequency into any FFT display you want to use.  You might be able to get it to work for you by replicating this file structure.

Thank you, Nathaniel.

I pulled down a small segment of one channel. However it will not playback in gnuradio.
I think the dataset is OK, it appears to be the gnuradio Digital RF Source module that's the problem.
The error that I am getting has already been submitted by other folks on github:
"py_io_signature' object does not support indexing #3"
back in December 2018, it appears not to have been addressed yet.

Hi guys!

Last week some people asked for copies of my Field Day DigitalRF data. I put it up on a SFTP server:

User/URL: hamsci at w2naf.d2g.com<mailto:hamsci at w2naf.d2g.com>
Password: hamsci

The connection is slow (raspberry pi connected to a residential xfinity connection), so try just taking what you need at first. I'm going to be working on making some summary plots of it over the next few days.
