[Elecraft] K3 Hissy and Noisy Audio

[Roy Morris]

I concur with what has been said regarding the "hissy" audio.  The receiver audio seems to be on the mid-range to high frequency side without enough low frequencies in the passband.  Experiments with RX EQ apparently have not done anything to eliminate this hiss, but maybe the firmware can be adjusted to increase the low-end response of the receiver passband.  If this doesn't work, maybe a component change is in order.

I also think the noise reduction is too sharp in both SSB and CW.  Perhaps NR could also be improved with more low frequencies in the passband.
