WSJT-X v.2.1.0

[N7US]

I had the line in on the radio at 35, but it varies as I tweaked the Windows level.

I understand the TX audio processing has changed, and the operation (sensitivity?) of the ALC reading makes it much harder to get the fifth segment to flicker.

I went back to JTDX (and JTAlertX), which is much easier to get the correct TX audio level.

What is the Line gain on the radio?


My values:

For transmit:

Computer SPKR level  @ 30 or -18 dB

WSJT-X PWR at mid scale, thus  Transmit Digital Gain is -17.3 dB

K3S Line gain at 25.

For receive:

Microphone (USB Audio CODEC) = @ 27 or -10 dB

K3S   Line Out =  Normal 010


These values above taken directly from the computer, WSJT-X, and K3S. This is with WSJT-X version 2.1.0 64 bit running under Windows 10 Pro. The computer is a HP EliteBook 6930P with Windows 10 Pro, version 1809 (OS Build 17763.615).   Processor is P8600 2.40 GHz 2 cores,  RAM 4.0 GB.  In other words....nothing special in terms of hardware or processing.

If you are running any other interfaces, software, logging applications, station control software or hardware interfaces, then all bets are off. I just have a single USB cable between the radio and computer.   When I use WSJT-X or any other application that is all that is running, other than my antivirus and malware applications.    Everything else is shut down or exited and closed.

I'm a happy camper and these work 100% reliable for me.  It is simple and I like it that way.

Yes as I wrote earlier there are 3 places which are "in series" if you
will, that affect the audio level to the radio.  In order: (a) Windows
SPKR level. (b) WSJT-X PWR slider, (c) K3S Line Gain.

I don't know anything about TX audio processing changes and I don't find
it a challenge or any difficulty to get the 5th bar to flicker.    Again
I will comment that I find the default WSJT-X TUNE frequency of 1500 Hz
does appear to cause a beat with the ALC meter display refresh rate.  
It appears as a fluctuation or pulsing of the value.   By moving the
TUNE frequency away from 1500  a 100 Hz or so I find the issue is resolved.
