USRP master clock rate setting in SHOUT long profile

[Yiyang Li]

Hi all,

I have collected good captures for the OFDM sounding packages, the only problem is that the captures happened with 32Msps instead of the desired 30.72Msps. We are suspecting it is because incompatible master_clock_rate on the USRPs but I have not found any documentations on the SHOUT long profile in terms of configuring USRPs throguh gnu radio commands. Is setting master_clock_rate=61.44e6 something configurable, and how? Thanks for helping!

Best,

Yiyang

This is probably something you can change by editing the `radio.py`
file in the Shout source that initializes the radio. I don't recall if
there is a command line option to pass through a master clock rate.

I took a quick look, and there is an `--args` argument for the
`meascli.py` Shout client that runs on the nodes attached to radios.
You can probably pass through the master clock rate by doing something
like:

--args "master_clock_rate=61.44e6"

Thank you Kirk! Will take a look.
