11804RE: [wsjtgroup] Wide Graph Display - enhancement
- Oct 6, 2013Thanks, Joe. I will experiment more with sound settings in combination with
WSJTX settings. Since you are able to see the entire cumulative graph
"above ground" then I should be able to as well. With my current settings,
I can't let the signal get above about 30 db with waterfall whiteout
beginning - and that is pretty much independent of the type of display I am
using. I have been using Linrad and Default mostly.

I set-up WSJT and the sound card as follows using Windows 7/Windows 8:
I set "level" in the Windows driver (Level tab for the input device in
Windows Control Panel) to 80. I preset the "Line Out" in my K3 to 10 and
set the input control on my interface to 0 (fully CCW). I then adjust audio
input control of WSJT for 0 dB.
With those settings, and *no antenna* (or dummy load), I adjust the input
pot of my interface until the WSJT level display (lower left) shows between
15 and 20 dB - on just the "noise floor" of the rig.
When I connect an antenna, the WSJT level indicator will generally show
about 30 dB on 20 meters between x:49 and x:59 (absent any CW ID). The
strongest audio will generally run up to 50 - 55 dB and peak signals will be
roughly 10 dB *below* clipping level of my sound card.
With that configuration I show a nice variation from back with no signal
through orange to white on the strongest signals with Zero at 0 for
"Current" or zero at +5 for "Cumulative". Note: I use the LINRAD palette
since that is most "familiar" to me from other software. I also turn off
AGC in my receiver.
