[Dominic Spill]

Hi Hutz,

I'm sorry that I missed your email last week, I'm not sure how that happened.

Have you checked your antenna?  Have you tried with the amplifier
switched off?  What are your gain settings in gqrx?  Could you take a
screenshot to show us what is wrong?

Good, it's goof to update both the firmware and CPLD at the same time.

This is the latest release, which is a known good firmware.

It looks to me like the version of the firmware is correct, there is
no need to use the DFU update procedure.

Did this complete?  Was this all of the output?  Those messages are
mostly warnings and appear whenever updating the HackRF using
dfu-util.

When the DFU procedure completes it restarts the HackRF running the
newly downloaded code.  Did this not happen?  Were there any other
error messages?

Do you mean for sending from one HackRF to another?  You can use any
radio system that GNU Radio supports.  I suggest looking at the list
in the GNU Radio gitHub repository:

Thanks,
