[Elecraft] K3 SSB Noise Reduction

[Tony Fegan VE3QF]

    Yes Mark you are not alone. I normally run with the AF gain set at 9 
o'clock. but when the NR is on I have to advance to nearly 11 o'clock 
for the same volume from the speaker. In config , my AGC settings are 
all at the default and AF GAIN is set to Hi.
    I have a couple of skeds where the signals run close to the noise 
level. I have a 2.1 KHz filter and I usually run with a bandwidth of 
2.0KHz under these circumstances. I am constantly switching the NR on 
and off but I sometimes forget to reduce the AF gain before switching 
off the NR. I get a rude awakening with a blast from the speaker.
    The NR does work very well and greatly improves the readability when 
signals are close to the noise level. The more agressive NR settings 
reduce the volume still further.
    I would prefer the audio level to be as close as possible whether 
the NR is on or off. I hope this can be taken care of soon.
