Re: Are there firls and kaiser filter methods for C++ OOT?

Re: GNU Radio install on Mac Monterey

Ok, long story short, I was able to install and run gnuradio on macOS. In MacPorts, I uninstalled gnuradio and all dependencies, then reinstalled gnuradio. When I ran gnuradio-companion in terminal, I got an error messages similar to those described in: https://github.com/gnuradio/gnuradio/issue

Re: Are there firls and kaiser filter methods for C++ OOT?

Geroge, I posted the working code a few messages ago. Try to check this out. BTW as far as I can see those two arguments are optional (window type and beta). Try to run your code without them and check if it works. wt., 22 lut 2022 o 19:25 George Edwards napisał(a): > Hello Vasil and Marcin, >

Dave, I came across a situation that you described. I had a breakpoint, and I disabled it after hitting it. Sure enough, it brroke there again. It seems to be hitting it from another thread. So, check your call stack when you come across that situation and it may be that it is coming from a

" The LO synthesizer on the B210 is shared between the two channels, so only your 2nd tune request is actually "honored". Thanks for this answer, so both are always tuned to the same frequency. I should have bought 2 B200 as it also seems that the bandwidth is limited (not 2x56MHz) if you use both
