Sorry for for that.... I thought the "imoprt" block was a type of block that I could create from the modtool.
but In the import-block I can import modules. But I can still not import actuall code into my top_block and I can not call functions from the import-block. What I want to avoid is to add code in the top_block manually since I'm normally using the GRC to generate the top_block. /Daniel Date: Mon, 6 Jul 2015 09:43:24 +0200 From: marcus.muel...@ettus.com To: discuss-gnuradio@gnu.org Subject: Re: [Discuss-gnuradio] Additional code to GRC flowgraph Try the block search (magnifier button in GRC), type in "import" :) On 07/06/2015 09:33 AM, Daniel Brogren wrote: Hi again I have a MPSK SNR Estimator Probe and a Function Probe that calculates the SNR.

I would like to add some additional code to the top block but I still want to be able to work with the GRC.
