K3 Beta 3.27 NR makes audio all but disappear

[Robin Diane Goldstein]

greetings all... i'm still a relatively new K3 owner but realize the
functionality of firmware, especially with respect to DSP functions,
such as noise reduction, is hotly debated, as it is a
work-in-progress.

that said, i'm an SSB-only op and found that the 3.25 version of the
Noise Reduction system, while awkward (in that you had to turn it off
and then on again in order to have the FIR filters rebuild
themselves) was actually useful...  an ssb voice signal burried in
noise could be helped with a setting of 2-2 or 3.2 without
fundamentally changing the characteristic sound/overtones of the
original audio.

i was, therefore, eager to try 3.27, which came out tonight... the
first thing i noticed is that pressing the NR button effectivelly
makes my audio disappear almost completely.  even with a very
strong/clean signal against almost no noise, pressing NR regardless
of the underlying setting, will cause the audio to go far far away...
if i wait a bit (30sec?) some audio sometimes comes back, but it
seems heavily filtered with no overtones (underwater bubble talk is
how i describe it)...  i dont know if 3.27 works great for CW, but
for SSB, while 3.25 was somewhat functional, 3.27 is a non-starter.

have build 2102, btw, in case there's some other issue that's causing
this feature to work well with some rigs but not with others (ie,
mine!)
