[Discuss-gnuradio] not receiving sound of FM receiver
Thanks Nino and Marcus for the answer I also get some peaks but no sound just like you on n210 with WBX. I set the gain to 30 and using VHF Armature antenna for 100Mhz. still no sound. the same antenna works with any radio receiver. I have spent plenty of time to get something out of n210 with no success. can you help me on this or show me a working FM example or can you give me the right setting parameters for UHD Source WBFM receiver blocks on GRC.I have downloaded some UHD examples from internet but not working. By the way, I have put the constant block after WBFM receiver not before as Marcus suggested.

I found the antenna was the issue, I followed a tutorial on building a home made fm antenna and set the gain to 300 on the N210. When I get to my computer I'll mail you the GRC file I'm using :0) Nino ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Have you tried setting the gain value higher also what antenna are you using? Nino ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

If you've adapted some of the classic examples to UHD, you may need to put a multiplier block right after the UHD source. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
