Re: [Discuss-gnuradio] Multiple hackrfs

Sylvain,

Thank you so much for the help, I thought I had read through the documentation 
for the osmocom source, but obviously I missed the one about the brackets, so 
thanks for taking the time to explain that to me. And that makes sense about 
the 2 osmocom sources now that you explain it in that manner. Have a good day!
