I gave myself a toy, one of those cheap USB Software Define Radios, and would like to use it on my C7 box. Having wasted some time on it, I gave up and installed Ubuntu on a USB HD so I can boot that to play with SDR. The Ubuntu GQRX installation is well documented and went off without a hitch. but I just hate having to boot something else on my main box (partly because it also runs a mailserver for my personal domain, partly because, well, I just want my box running CentOS, not Ubuntu.) Searching through SDR info on line I see someone has documented installing all the bits for C6, but I suspect the process is different for C7. BTW, I installed the various bits I could find from, er, I think some came from li.nux.ro, some perhaps from epel, on C7, but couldn't get them to properly function. Worse, when the USB radio is unplugged from the system, it locks up hard. then a few days ago, I had been playing with it using the UBUNTU install, did a reboot and for kicks fired up the GQRX on Centos, and lo and behold it worked! I tried running it on Centos yesterday and it reverted to type, i.e., lock up hard. I suspect that Ubuntu is leaving some hardware in a state that allows it to work on a subsequent Centos boot (without poweroff), but no clue what. So, if anyone can point me to how to use it on C7, I'd greatly appreciate it. thanks in advance!
