[Elecraft] CODEC

[Ed W0YK]

My experience differs.
When the K3S came out, I upgraded all my original K3 radios with all the available K3S parts.
I've enjoyed the simplification of the digital audio and the elimination of the Serial-USB adapter.  I seldom adjust the audio levels and certainly no more often than with the analog audio.  Across a weekend RTTY contest there might be a few very minor adjustments from 10 thtough 80 meters.
One annoyance is that the Windows level applet gives only mono adjustment for the K3 stereo LINE OUT but stereo adjustment for the mono LINE IN.  It appears that Windows is choosing stereo Playback control for LINE IN and mono Recording control for LINE OUT.
There must be a way to correct this, but I haven't found it.

I had a K3 in service (now a spare) for about 8 years before getting a K3S.  I 
didn't do WSJT but some RTTY and PSK using the Line In/Out into my Lenovo laptop 
internal sound card.  Worked like a champ, started with zero and now have 255 
countries on RTTY.

I tried to use the K3S USB sound and got tired of the incessant need to fuss 
with drive and VOX levels.  I requested many times for firmware that would save 
VOX settings by mode to no avail. (When I had another issue, Elecraft Support 
actually told me that they didn't recommend VOX on digital modes.)

I've returned to using the analog audio in/out of the radio and the laptop sound 
card, which is higher quality anyway.  (I have a TASCAM US-100, highly 
recommended by the resident audio guru, but haven't found it to be any 
advantage.)  This also makes it easier to resort to the spare radio when necessary.

In WSJT-10 they have Rate In/Rate Out monitors that should normally run at 1.000. Using the K3 analog audio these always stayed right on 1.000 but now that I am using the USB audio they are jumping around quite often and getting out of range indicated in WSJT with a red marker.  I have tried two different computers and the same result.  I tried changing the sample rate in the computer audio settings but no change in the problem.  I plan to go back to analog Line In/Out on the K3S unless someone has an idea on how to settle down the Rate In/Out fluctuations.  I have not found anything in the K3S that might affect this.  You can reply off line if you like.  73 Mike K4PI
