and ticket:199

I recently “upgraded” to UHD + GNURadio3.4 and they are giving me a hell
of a time to get my old codes working. I used to be able to use without a problem with GNURadio3.2, but after
upgrade I am getting seg faults. I googled around and found an old
ticket:199 that seems to describe my problem.

I then saw from the master tree that Tom wrote, “uhd: moved
fm_tx_2_daughterboards and usrp_spectrum_sense to gr-uhd/examples.
Neither are working properly quite yet.”

Is there any plan to bring back spectrum_sense? Or are we encouraged to
switch entirely to uhd_fft?
