That question has and will always get an "it depends" answer.
Understanding the cause and effect of buffer sizes (audio and DSP) and
their interaction with sampling rate is paramount before you can answer
that question. There is also a very important PC resource dependency
too; smaller audio buffers require more PC resources.
You can begin here on your buffer knowledge quest.

In my case, the answer is neither. I use 512.

For my part, EVERY time there is a new code load, I run the calibrations.
This is a huge piece of code and I never trust changes to be free of
unintended consequences ESPECIALLY if I had anything to do with it. ;-). I
regularly chastise that guy in the mirror while I am shaving every day (when
I remember to .....).

I gotta say the TNF is an amazingly awesome feature. Being able to
tune out individual birdies in the passband while on 80m AM is just
amazing. Works so well, and the user interface is so simple and
effective. Absolutely class A1 implementation, guys!
I also did a WBIR reset today. A long long time ago (in a galaxy far,
far away?) I loaded PSDR V 2.x, which did the WBIR calibration on my
rig. Not knowing any better I wasn't concerned in the slightest about
my antennas being connected. I did see some articles that doing WBIR
cal with antennas connected can lead to some not so good results.
I've been meaning to redo this, but hadn't got around to it. Well
today I had time and boy am I glad I did. Living in the Houston area
means, yep, there are a few pretty strong signals around. After
redoing the WBIR and the level calibration, it's like I have a new
radio. It's so QUIET! Really really amazing. I don't think
conditions changed that much, but man, it seems to be a pretty
significant difference.
Just thought i'd pass along my kudos and good fortune!
73,
Michael
