Re: [wsjt-devel] QMAP query

Hi David

I will have  a look here also.  I am not familiar with those settings, yet,
in SDRC. I more or less used it 'out of the box'.

Re: [wsjt-devel] QMAP query

[Joe Taylor via wsjt-devel]

Hi David,

It seems that SDR Console stopped sending its I/Q data stream to QMAP, 
or for some reason QMAP closed its input port.  Unless you can find a 
way to replicate this unwanted condition at will, I have no particular 
suggestions.  I have never seen a comparable fault in the Linrad-to-QMAP 
setups that I use regularly.

Today, all was running fine. I clicked on a station in “Active 
stations”, and WSJT-x took me to transmit, and the QSO ran as normal.


However, after my first transmit period, on return to receive, QMAP was 
showing no input signal, whilst SDRconsole was displaying normally. 
WSJT-x was working normally. I closed QMAP, and re-opened it, then it 
was working again.


I obviously need to try again a few more times, but didn’t have time today.

Any thoughts?

Re: [wsjt-devel] QMAP query

[David Hilton-Jones via wsjt-devel]

Many thanks Charlie

 

Done some further testing this morning and I think I have a partial 
explanation/solution.

 

Windows 10

 

WSJT-X rc2

QMAP

SDRC

RSPDx

 

No moon to play with at the moment, but just played with hitting “Tune” in 
WSJT-X.

 

If the auto-mute in DRC is off, then there is no problem. The QMAP thermometer 
reads ~48db.

 

If auto-mute is on, AND the Peak and Mean options are set to -20db or lower, 
then QMAP does not recover when going to receive. Thermometer is zero. Have to 
exit and reload QMAP then OK.

 

BUT, if Peak and Mean set to 0db, then after transmit QMAP returns to receive 
as normal.

 

Will be interesting to see if you can duplicate.

Hi David

 

As far as I know, this hasn't been reported before.

 

I've been running SDRC to drive QMAP now for some time here, pretty much since 
SDRC build 3117 came out, and also haven't seen this behaviour.

 

The only problem I had, at first, was to have SDRC's demodulated audio 
outputting to the same audio 'port' as WSJT-X uses for transmitting, cured by 
muting SDRC.  It did not result in loss of signal to QMAP as you are seeing.

 

What level do you see on QMAP's thermometer normally?

 

What operating system are you running?

Hi David

As far as I know, this hasn't been reported before.

I've been running SDRC to drive QMAP now for some time here, pretty much
since SDRC build 3117 came out, and also haven't seen this behaviour.

The only problem I had, at first, was to have SDRC's demodulated audio
outputting to the same audio 'port' as WSJT-X uses for transmitting, cured
by muting SDRC.  It did not result in loss of signal to QMAP as you are
seeing.

What level do you see on QMAP's thermometer normally?

[wsjt-devel] QMAP query

[David Hilton-Jones via wsjt-devel]

I am using rc2, SDRconsole with RSPDx, and QMAP

Today, all was running fine. I clicked on a station in “Active stations”, and 
WSJT-x took me to transmit, and the QSO ran as normal.
However, after my first transmit period, on return to receive, QMAP was showing 
no input signal, whilst SDRconsole was displaying normally. WSJT-x was working 
normally. I closed QMAP, and re-opened it, then it was working again.
I obviously need to try again a few more times, but didn’t have time today.
