Hello,
I am working on making a binary format for rtl_power to save space on
my server for observing the spectrum. I am wondering if anyone else would
be interested in this idea.
I am hoping keep the same format in terms of how the data is organized in
the file but instead of using text use some form of binary format. For
example for the date and time I think using a unix epoch timestamp would
work.
I am hoping to receive any comments or criticism.
Thanks, KD9KCK
I can not transmit signal please help ? I am taking a low signal 165MHz after device is stopping to send signal. Why ? Please Help? İn this picture I take a very low signal after device stopped to send signal . Why I dont understand ?

Dear all,
I just subscribed to this list since I encountered an issue after
pulling the latest git commits.
> lib: use interface 0 altsetting 1 instead of interface 1 ...
> This makes osmo-fl2k work again with Linux 5.5.0-rc6 or later,
On my system (Debian stable, kernel 4.19) this change results in
"Error enabling IF 0 altsetting 1". Reverting to the
previous version (with Interface 1) solved the problem for me.
I will investigate a bit more whether it is related to kernel or
libusb versions. Or have I missed some other required configuration?
Best regards,
Carl-Fredrik SM2YHP

Hi all:
I'm trying to build the latest gr-osmosdr package from the gr3.8 branch, but I'm
seeing some unusual errors, and I'm not quite sure what the deal is.
I'll note the following:
- I had errors related to existing python2 packages, so I tried building with Python3.
I'd be less than surprised if someone says that this is the cause of the issues, but
personally, I'd like to roll with the Py3 products from now on, what with Py2 being EOL…
- OS is Arch.
My cmake command was:
```
cmake \
-DCMAKE_BUILD_TYPE=Release \
-DPYTHON_EXECUTABLE=$(which python3) \
-DPYTHON_INCLUDE_DIR=$(echo /usr/include/python3*) \
-DPYTHON_LIBRARY=$(echo /usr/lib/libpython3.*.so) \
-DENABLE_DOXYGEN=1 \
-DCMAKE_INSTALL_PREFIX=/usr ../
```
Output from cmake:
```
