Hi Kyle - after I build gr-fhss_utils and run the tests, all 3 tests fail.
Do the tests work?
I did a pull but it was up to date.
I'm running gnuradio 3.8.2.0 on Debian 10 or buster.

just did a quick test, couldn't be simpler
max_i reports the argmax of the fft, with wrapping
So in the above example:
* 1 kHz -> 1
* 5.5 kHz -> 5
* -1 kHz -> 31
* -8 KHz -> 24
increase from 32 to increase resolution

Hi Kyle,
is there any document for how to use the block in gr-fhss-utils
especially for fft peak block. what is the two output of fft peak?

cmake version is too low so i can not build gr-fhss
gr-fhss has a 3.7 and a 3.8 version if you check the tags on github
how to store max result to a gui label?
qt-number-sink maybe

Hi Kyle,
Thanks. my cmake version is too low so i can not build gr-fhss. i try
to use fft->max but how to store max result to a gui label?

2 things that come to mind:
1. stream -> fft -> argmax
2. in sandia fhss utilities they have an FFT Peak block that does
what you want

Hi all,
i want to see the fft of the signal and also want to detect the peak
frequency if there is a peak signal.
how to achieve this?
