This "should" be the final update in this thread (assuming no other gremlins
The use of the "Low IF" option in the SDRPlay configurator appears to have
resolved the SDR stability issues. It was running for over 24hrs solid
during IOTA, I'de call that stable!
I would recommend that a note be put into the N1MM+ manual in the
Spectrum Window -> SDRPlay section to advise the use of "Low IF"
if users are experiencing stability problems.
Many thanks once again to all those who helped!
