locked Re: Decode lag
Just managed yesterday to get JTDX working reliably on Linux ubuntu 20.04LTS OS ; IC-7300 rig; JTDX v 2.2.0rc.155
Resource monitor on Panel indicates max of up to 40% CPU when
JTDXjt9 -s time slice is active all other workspace timeslices are
in range of 11%- 20% CPU usage. Max Mem usage with all apps
running using multi workspaces less than 4 GB and zero swap space
Apps running, weewx wx stn software, firefox 9 tabs open, chromium 6 tabs open but not streaming (streaming sites),chrome (qrz.com db lookup, hamqth.net db lookup, Cdn Government ham call db search, PSKreporter) GridTracker, Thunderbird email, JTDX,
When I see the Band Activity window top line showing headers for text message columns and Avg.= and Lag= and NO signal coming in I get Lag -0.1 /0 as traffic shows up and increases the Lag indicator shows -0.04/40 with Avg=0.18.
The time, freq and DT I understand but I can't find how to interpret the Lag or Avg figures or understand what exactly they represent. If I click on Decode button Lag just goes to /54 and remains there until the next decode cycle.
Can anyone point me to a good wiki or floss type manual explanation respecting Lag and Avg measurements are arrived at as the ops manual and user manual do not seem to touch on the subject at all let alone even in sketchy detail.
Seems strange that the resource monitor/task manager
taskbar panel indicators indicate max CPU resources peak out
at 40% only when time slice devoted to JTDX and the rest of
the time less than 20% and memory never exceeds 1/8 of what is
available that the software would seem to be taxed so high as
contact messages increase only to effect Lag and Avg. so
Thanks all pointers appreciated.
