Use the firmware and FPGA image that corresponds to the distribution of UHD
that you have chosen to use. I don't think it's necessary to update
firmware unless you're getting runtime errors from UHD (it will explicitly
state that your firmware is not compatible with your version of UHD).

I'm having trouble trying to implement an energy detector in GNU Radio.
I want to find empty channels that have a signal power less than or
equal to the FCC's -114 dBm detection threshold. I've been modifying the
usrp_spectrum_sense.py code that came with GNU Radio, and it's been a
headache trying

You can use either antenna for RX.
In general, you should direct USRP & Ettus-specific questions to the
USRP-Users list only. This list is for GNURadio-targeted questions.

You have started 20 new threads on the GNURadio list in the last couple of
weeks. Most of them are one-sentence questions that aren't easy to
understand.
The GNURadio community is in general very helpful, but you will get many
more responses if you first try to find answers on your own,

It's my most
serious personality flaw :-)
