So, it seems like no official place exists yet. Some things are mentioned in the issues on github, but they don't contain very much information at the moment.
So, to summarize what I found out so far: To get the xtrx version of gr-osmosdr running with the USB enclosure, it is necessary to replace "/dev/xtrx0" with "usb3380" in xtrx_sink_c.cc and xtrx_source_c.cc Then the dwvice can be used with the osmosdr source, when specifying the device as "xtrx". For what I have not found out yet: How to select other antennas than the first one. In the source code, I find references to "RXL", "RXH" and "RXW", however I have no idea how those map to the two available receive antennas, or what exactly the "AUTO" option does. I also don't know what the different gain settings do. There seem to be "LNA", "TIA", "PGA" and "LB". Judging from the acronyms, the probably mean something like "Low noise amplifier", "Transimpedance amplifier", " Programmable Gain Amplifier" and "Loopback". But I have not found any further documentation on what function each of them serves in the XTRX. I am also worried because I have not yet managed to receive any useful signal at all. The transmit side seems to be working, although it has a bug, that the frequency isn't set correctly unless you change it at runtime. But I have not yet managed to receive anything, or even see a difference in noise level between a connected antenna and a dummy load. This might be an error in my usage of the software (e.g. wrong gain settings), or it might be hardware related. One of the small cables in the case seems to be slightly damaged, however I would still expect some signal to pass through it. I would be happy to hear how this experience relates to that of other users. Am 4.
