[Discuss-gnuradio] BasicRX daughtercard for Ham Radio

Dear Sir, Referring to [1], the correct daughtercard for HF Communications is LFRX and LFTX. As a Ham radio receiver, could BasicRX be used instead of LFRX? Regards, Activecat. [1]. http://www.ettus.com/content/files/kb/Selecting_an_RF_Daughterboard.pdf

Re: [Discuss-gnuradio] Problem with large number of inputs.

Mostafa, I do not think you have truly run the complete codes using Qtcreator, because that doesn't have a gnuradio runtime (the scheduler). At the other hand, your problem sounds more like a c++ coding error rather than gnuradio-specific. The helpful approach is 1). Put up the OOT into github.
