I think it's a bug that happen when you start Quisk and you don't click on any band.
In this case it seems to ignore the tx level setting.
|
Hello,
On my Quisk version 4.1.52 (linux), I have a tx level in one band of 0,
because I need this "low" power output to not burn my PA that is connected to my HL2.
And it works really well.
I noticed, that if I power cycle the HL2 and restart the software,
then it transmit full power. Why my tx level of 0 is ignored ?
I guess that I must miss something in the config to restore the values.
Do you have any clues ?
Thank you
Julien, F4HVX

Hi Jim,
Attached is a short summary of the IQ study. After doing that and then playing with Quisk with the new softrock_tune_vfo.py file, I conclude we have a good way to operate a Tayloe-style SDR with Quisk. I don't find it at all awkward or unnatural to use. With
that, I'm also betting Quisk's existing IQ correction means can provide whatever results one might seek, depending only on the user's willingness to provide enough calibration points.
Thanks very much for that new softrock hardware file. Using it today, I made my first FT8 contacts with Quisk. Maybe that gets me off the WindowsXX marketing-driven treadmill, at last!

Re: I/Q Phase and Amplitude Calibration for Tayloe-style SDRs
Hi Jim,
Today, I had planned to work on plotting the results of the little offset measurement exercise, but was diverted when I found your last posting with the link to the new hardware file. I copied it to my home directory, changed the config to point to it and fired up quisk. It does indeed appear to do exactly as we discussed. I have not noticed any of the clicks or pops we speculated might occur. Tuning by waterfall clicking or scrolling works as hoped. Larger leaps are accomplished by clicking appropriate display digits, up or down. The up/down arrows just produce a transient display displacement, with no other effect. So, with this patch, we shall just? ignore those buttons.
It would have taken me considerable time to learn enough to write that little hardware file. You made it look trivial. Thanks so much.
As time permits over the coming days, I will do the i/q calibration with this patch in place and see how it looks by comparison to the other measurements. My goal now is to write a short summary report and post it here.
For others who may be interested, the radio here is a Multus-Proficio SDR. It emulates Softrock and Peaberry hardware with respect to usb tuning control. The expectation is all radios of that ilk will work with this.

Re: I/Q Phase and Amplitude Calibration for Tayloe-style SDRs
I would imagine that a UHFSDR would work as well ....

Re: WSJT-X / Quisk - Software problem
OK, glad it's OK.
Whenever I have a new SBC, I copy quisk_settings.json from a current SBC and find it's AOK.

Great! I think it's time for a new setup from scratch now. Obviously, something is wrong here.

How to set up quisk for wsjtx
Hello everyone :-)
hope that I'm right here with this problem!
First - there are no difficulties to work with FLDIGI - but if I start WSJT-X there's no audio (I/Q) output anymore between Quisk and the soundcard until I restart Quisk. I've done the installation according to the documentation:
"... Using PulseAudio is the easiest method because Quisk can set up the loopback devices when it starts. Set Digital Input to pulse:QuiskDigitalInput.monitor, and set Digital Output to pulse:QuiskDigitalOutput. These names should be on the drop down list. If they are missing, make sure that you didn't set "show_pulse_audio_devices" to False in your config file. Then restart Quisk. In your digital program, connect the digital input to QuiskDigitalOutput.monitor and the digital output to QuiskDigitalInput. These names will be on the sound menu in wsjtx, and you should be receiving and transmitting digital data.
Fldigi only has a PulseAudio check box, and there is no way to set the proper device. In this case, first install the program pavucontrol to control PulseAudio. This is a useful program to control and understand PulseAudio even if you are not using digital. Set the Quisk devices as above. Now start both Quisk and Fldigi, and then pavucontrol. The Playback and Recording screens in pavucontrol will show the devices being used. Change the Fldigi playback to QuiskDigitalInput, and the Fldigi recording to Monitor of QuiskDigitalOutput. Then everything should work ..."
PTT works right and the program is receiving well. Did I overlooked something?

Re: Missing tutorials or bad links?
Hi BruceN,
Quisk wasn't mentioned on their website.
In any case for HL2 a recent version of quisk is the best option. When I have pisdr_v2.fixed.zip installed I'll build 4.1.52 or whatever is latest.
73 ... Sid.

Re: WSJT-X / Quisk - Software problem
Hello Karl Heinz,
thank you very(!) much for the efforts which you have made for me. The settings are exactly the same on my Pi. But the OS is Buster. Maybe this makes the (little) difference (between function or not).

Re: Missing tutorials or bad links?
In my previous post, I mentioned a couple of products with which I'm impressed.? Here are the links:
PiSDR:?
The PiSDR takes the I/Q signals from SDR hardware and uses them to work with Quisk on Linux.? It will work with a special version of PowerSDR on Windows.? They provide the special version of PowerSDR.
I use a RS-HFIQ for my SDR hardware.? Nice machine.? A 5 watt transceiver.? Here's the link:
They also make a pretty neat 50 amp for a reasonable price that works with the RS-HFIQ, the Elecraft KX-3 and I suspect many other rigs.
Check them out.

Re: WSJT-X / Quisk - Software problem
Karl-Heinz,? here are three screenshots of my setup (two from WSJT-X, and one from Quisk). This is what works for me and also works on a Raspberry Pi (but I don't have one set up right now, I would have to restore one of?the SD card images to actually be able to take screen shots).? This is the audio setup in Quisk:  Here is the rig setup in WSJT-X:  And here is?the audio setup in WSJT-X:  If you still cannot get it to work, maybe it's time to restore one of my Raspberry ?Pi systems to running Quisk and WSJT-X.

Re: Missing tutorials or bad links?
Those links take me to , I guess linuxplanet.com no longer exists as a standalone site.
The PiSDR image does not come with quisk thankfully so I would recommend building and installing quisk using , fielding questions here if needed.
BTW thanks for alerting me to PiSDR, never heard of it before, perhaps I can get my LimeSDR-USB to work using it on my Pi3B.

So, if someone has copies of those tutorials, it might be good to post them in the Files section here.
I'm setting up to use an image provided by PiSDR for a standalone application which uses Quisk.? I would hope that I can upgrade to the latest version.? It appears that the PiSDR uses an OrangePi3 board instead of a Raspberry Pi.? Wish me luck.
