[hpsdr] FW: NF Interrupts / buffer size

[DL7JP]

Meanwhile I re-compiled PowerSDR with an additional choice for a 4k Buffer 
in setup.cs/this.comboAudioBuffer1.Items.AddRange: still the same problem.

So, either increasing the buffer is not that simple (I just glanced over the
code...), or the reason for the problem is another one.

Subject: NF Interrupts / buffer size

Dear all,

I received the Janus/Ozy boards a few weeks ago, and recently succeeded with
setting things up.
So, firstly, thanks to all who are involved for the great work!

There is one issue I am still struggling with: I notice occasional
interruptions of the NF coming out of Janus; it is acceptable for 48k
sampling, but gets nasty with 96k. CPU load is < 50%, so I guess this is not
the problem.

This NF-Distortion is minimal with buffer size 2048, anything lower produces
more. However, a 2k buffer seems still not enough for 96k sampling, so I am
wondering if there is a way to increase the buffer size to 4k.

Thanks for any hints ... Joachim.
