use osmocom source for portability
Sorry, but both apps don't work for me. the osmocom app complains about Param - Value(value): Value "len(decimation_lpf)" cannot be evaluated: name 'decimation_lpf' is not defined
and the wav file reader complains about Block key "variable_low_pass_filter_taps" not found in Platform - grc(GNU Radio Companion) Error: Block key "fosphor_glfw_sink_c not found in Platform - grc(GNU Radio Companion)
Which version of gnuradio are you using? I'm using a pretty fresh development build. On Jul 14, 2015 2:28 AM, "Volker Schroer" [email protected] wrote:

That would do it. I'll send you a screenshot illustrating the changes... On Jul 14, 2015 8:46 AM, "Volker Schroer" [email protected] wrote:

I'm using v3.7.7.1-166-g28f69a54.
Fosphor is just a visualizer; you could replace it with a regular QT or WX waterfall.
Newer gnuradio has helper blocks to calculate filter taps rather than making the user remember the magic to invoke the filter designer: lpf_taps = firdes.low_pass(1.0, audio_rate, 4.9e3, 1e3, firdes.WIN_HAMMING, 6.76)
