DQPSK/GMSK receive strengths

Is there a way to know or log (in the verbose logging) the maximum
received strength of a packet- or running max perhaps over a period of a
few seconds? I’m trying to measure it with a scope and coming up short-
I think I have some faulty hardware in the loop here, but that’s what
I’m trying to diagnose. If there’s a way that the USRP can report the
received strength while using tunnel.py that’d be quite useful to me at
least.
