Hey Andy, Thanks for the reply. I will take another look at the code I think I know what to do now. I will make sure the mailing list is included from now on. Thanks again. Josh > On Mar 11, 2016, at 10:20 AM, Andy Walls wrote: > > Hi Josh: > > I misread your question. See my additional an

Andy and Nathan,I really appreciate the insight, resources and the direction you have provided. I am starting to look into adding the constants to the blocks. When I run into questions, I will check in on irc or send another email.Thanks again for all of the help!JoshOn Mar 06, 2016, at 01:08 PM, A

Hi Josh, Glad you're interested in GSoC and GNU Radio. These suggestions from Andy are pretty good, and any work that you've done on or with GNU Radio by the time we make decisions definitely improves the credibility and strength of your application (that's true for *all* students by the way... i
