[hpsdr] Fwd: [apache-labs] PowerSDR/OpenHPSDR mRX PS v3.2.18 released

[Joe Martin K5SO]

There are unfortunately subtle physical differences board-to-board and chip-to-chip on all of the hardware we use.  These differences can sometimes result in different behavior of firmware on some boards.  There are no features coded differently in the firmware versions mentioned.  
Minor signal-path timing differences between v4.1 and v4.2 are all that distinguish the two versions, in this particular case.  

If an earlier version of firmware works better for your particular board than does a later version then by all means use what works for you.
