[Elecraft] Regarding the K3 and high QRN levels

[Martin Sole]

Me too!

I'm not a K3 owner but I've had one here in the shack the past few weeks.
Judicious use of the AGC settings has made it noticeably quieter and sweeter
sounding than it was originally but as with all DSP radios I've heard it
still 'sounds' harsh/rough. The primary box here is an Orion 565 and my
baseline was coming from a TS940, maybe not the last word in ultimate
receive performance but still a good radio, that together with a Collins S
line have a quality of audio reproduction that I could listen too for hours
on end. All rigs are still on line for comparison so not much guess work. By
contrast I find the DSP radios a little tiring to say the least, maybe it's
the audio circuitry itself, the O565 uses a TDA1013B, what does the K3 use?
I find that reducing the filter taps from the default 199 makes the audio
smoother, though that brings other issues, can the filter taps be changed
with the K3? 

Cheers
Martin, HS0ZED

Getting crowded, hope it´s a big boat, I´m in there too.
