Re: [wsjt-devel] Transmit signal problems

2018-10-06 Thread Anders LA9NKA 

Hello.

Using v2.0.0-rc2 on Linux/Ubuntu 18.04, with an Icom IC-7100 using the 
USB-audio.


I've also been seeing this issue sporadically over the last week or so, 
but I'm having a hard time trying to reproduce it.


Seems to happen more often if I have been cq'ing, and get a reply, and 
dbl-click the reply just as the radio starts tx with my next cq (and tx 
msg changes from cq to reply on same period).


The behaviour then is as described by op earlier, tx starts at low pwr, 
and gradually rises to desired level over the first 5 seconds or so. 
When this happens, the next period(s) usually behaves normally without 
any issues.


Have also noticed sporadically small fluctuations in tx-power when 
pwr-slider is around -25 db (the radio's usb-mod-level setting is at 
35%). Giving the wsjt-x pwr-slider a bump up or down then seem to make 
the issue disappear.

First signal is 1.9.1 tune button (looks fine) followed quickly by 
RC2's tune button (yikes!!).  Both systems at full scale on the pwr 
slider.

I would hope this can be duplicated on somebody else's system.
And RC1 behaves badly too.


Just for the record, I have not been able to reproduce this issue here 
on OS X or Linux. I’m using latest development code - but nothing 
related to generation of the audio output has been changed since RC2.

[wsjt-devel] Transmit signal problems

Having a problem with transmit signals behaving badly when 12dB down or more on 
RC2.  The behavior I see is my output power gradually rises over about 3 
seconds and that's what started my investigation.  If above 12dB no 
problem...power is spot on when PTT is asserted...but this is just a symptom of 
what appears to be a bigger problem.

So I compared the signal being generated by RC2 with 1.9.1.The image included 
here is the tune signal from both WSJT-X versions going through the same VB 
audio cable recorded with Audacity so the audio paths are identical.
