[Elecraft] high back ground noise

[simon m0vky]

evening

i updated my k3S yesterday afternoon, to MCU 5.50, FPF 1.25, DSP1 2.87.

now, i have a high white noise (back ground) on my audio on SSB or when 
i press the PTT. this wasnt present before i installed the new firm ware.

the only change is, i have my k3S on RTTY. i turned of the audio via USB 
from the pc and this helped reduce, but not completely.

any ideas ?
