rtl_433 spends a lot of time whenever it hops from 433mhz to 915mz 
adjusting the minimum detection level based on noise (automatically).
I purchased a fine offset clone WH25 today which is on 433mhz to avoid this 
problem.
Perhaps what is happening is a lot of the archived results are getting 
nulls because the slower (WH32B) is not done communicating by the end of 
the archive_interval.
Note the short archive_interval = 30 or 120 seconds.  Is this way too short 
especially in my case?
