For Airspy support, the first step is to contact your distributor for high quality personalized diagnostics and assistance. Our distributors are nice people and have had all the necessary training to solve your problems efficiently. They can also escalate to the engineering team if necessary.
You can also chat with us using our community forum for sharing your experience or express your wish-list of things you like to see in SDR#. The discussions in our forum may get very technical by times, but never hesitate to post your question if you have any doubt.
As our SDR# software also works with different hardware, we often end up with specific questions about hardware we have very limited knowledge about. In this case, you should contact the manufacturer of your hardware.
For custom designs and projects, you can contact the engineering team.
