Installing a TCXO in the HackRF One
There is a many old manuals how to install TCXO. Like this https://ceworkbench.wordpress.com/2016/11/01/installing-a-tcxo-in-the-hackrf-one/
But I had two unresolved questions after.
First. All photos in manuals didn't show what exact pins must be inserted. I found it only on some aliexpress seller photos.
Second. Previous version of HackRF tools had hackrf_si5351c but new one don't. A new utility, hackrf_debug, replaces three older debug utilities, hackrf_si5351c, hackrf_max2837, and hackrf_rffc5071. (HackRF 2017.02.1 Release Notes)
To check TCXO execute the command:
hackrf_debug --si5351c -n 0 -r
If you get the response:
[ 0] -> 0x01
the HackRF has recognized and is using the TCXO.
