Subject: Transmit / Receive switching and station control
Presenter: Gavin Jacobs VE7GSJ
Agenda:
* Requirements for TX/RX switching
* VE7GSJ Solution (hardware & GNURadio Companion)
* Demo on 2m repeater

this might depend on how you install it
I see you are using and /opt/ prefix. I just install it with `pybombs install
gr-fhss_utils` and it works.
Maybe you are missing a dependency?
FYI the FFT peak block you want is a simple hier block you could make without
installing anything. Look at this
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.
-- Cinaed
Running tests...
Test project /opt/gnuradio/src/gr-oot/gr-fhss_utils/build
Start 1: qa_cf_estima
just did a quick test, couldn't be simpler
[cid:6a484104-b817-47bc-b349-49ea6aaca429]
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
