With the upgrade to Big Sur, I’ve been unable to initialize my B210.

Could the "decay" you are seeing actually be the phase changing due to
offsets in the carrier frequency? Unless you are doing some kind of
phase-locking
on the RX signal to correct for frequency differences between the
transmitter
and receiver, the apparent phase will drift a bit. Especially over
Note that the CBX lower frequency "limit" is around 1.2GHz
while the UBX is quite happy tuning down to 10MHz.
There are many powerful ambient signal sources between
10MHz and 1.2GHz. I suspect you are seeing those.
Nonlinearity being what it is, I have seen AM broadcast signals
appear in the sam
Yes this has been addressed before. But it is worth going through an
example of where the number might come from. Note that I do not work for
Ettus. I have Ettus radios on my bench here. (And like them a whole lot.)
I am not advocating for a different limit in the datasheet. However, I
