Hi Michael, Thanks for your input. I will change the grc script as you suggested. This may not solve my issue explicitly, but I want to learn gnuradio so everything helps. I have been running gnuradio 3.7 mostly because I have seen everyone's scripts use WX widgets and I found it easier to port them to QT via 3.7. Perhaps I should upgrade, but I found a small bug in 3.9 when I was using it. (I couldn't get and 'ID' for my 'QT GUI Tab Widget' so I could use ID@0, ID@1, ... with the my other QT GUI widgets and place them into tabs. I emailed the list, but didn't file a bug report and my email wasn't very verbose. Sorry. I ran a git rev-list to try to get an id as to be able to log the error. 'git rev-list --count HEAD' gave me 13291. Not sure if this will help you track it.)
Thanks again and take care, Chris On Mon, Aug 26, 2019 at 1:43 PM Michael Dickens <michael.dick...@ettus.com> wrote: > > Hi Chris - A few comments, more than anything else: > > * You're generating 2 sinusoids then pushing them directly into the audio > sink.
