Re: Latency constraints for remote operation?
Just an IP address, in format 123.45.67.89 ... no " or anything else.

Did you use the WAN IP address or URL? And in the latter case: with or without " etc? 73s Peter Op 25/11/2022 om 22:56 schreef Ben Cahill: I've connected successfully (for Rx only; did not try Tx) with a Remote Quisk rig in New Zealand (from East Coast USA) ... round trip was about 205 msec. |

Re: Hiqsdr usb blaster hookup
Hi Jeff,
The manufacturer of the board seems to have ceased activities altogether, hence it is hard to get data. The only think I can offer is a schematic (but you probably have that one). Dl2STG still maintains a web site a and seems rather active, he might be able to supply you with more info. I am still on FPGA version 1.4, which I updated several years back, and cannot find my own cabling.... 73s, Peter, PA3BIY |
Re: Quisk Version 4.2.12 November 2022
Hello Jim,
There is no reason for it to be on Config/Tx Audio and I just need to learn to look a little harder. I missed the shift to the Config/Status screen but its a more logical place to have it there with all the other sound and level information. Thanks for the info. 73, Graeme ZL2APV |
Hiqsdr usb blaster hookup
Hello all, I just joined the group. ?I had bought the hiqtrx with the Hiqsdr board quite a few years ago and got distracted back then. ?I¡¯m dusting it off and want to program the flash memory with new programs for the FPGA. ?I know I need a usb blaster and a special cable. ?Do I need to make up that cable myself? ?Can someone help me out with part numbers and pin outs? ?TNX, Jeff - W1NC

Re: Quisk Version 4.2.12 November 2022
Hello Jaroslav,
Thanks for the information. I see that I made an error on my message when I said "after a period of transmit the graphical display freezes on my remote.". It should have been after a period of transmit the graphical display freezes on my Ctl-Head. The remote server keeps working normally and when I restart my Ctl-Head client everything continues normally. I'm still suspicious that I am getting RF into my local lan though, so my message is more of a heads up than a bug report but if others start experiencing the same thing then that will help to define that. 73, Graeme ZL2APV |

I am also experiencing occasional UI freezes, but for me it happens also on the local machine (without any remote function) and even in the RX mode (i.e. no RF). For me it isn't 4.2.12 specific it happened also in the older quisk versions. When the UI freezes all other functions continue to work (RX/TX/rigctl control, ...), i.e. WSJT-X still works OK, just the quisk UI doesn't react to the controls and spectrogram/frequency is not updated. Quisk restart fixes it. As for me it happens max once/twice per a day, I haven't found time to debug it 73! Jaroslav, OK2JRQ Graeme Jury napsal(a): Hello Jim, |
Re: Successful new install on raspberry pi but fails to calibrate
¿ªÔÆÌåÓýThank you very much for your detailed analysis. I did read somewhere that the mountain in the middle is caused by bad phase and amplitude adjustment, but cannot seem to make any difference by adjusting same. Last night I heard a QSO between a couple of hams on 7280, but the softrock indicated they were on USB on 40!? I tried to find an image but couldn't, their QSO was the only one on the band. I did see mirror images on
40 CW this morning, but again, could not adjust them out. The
image seems to reduce but then goes back to the previous level. Perhaps I was a bit hasty in installing the unit in the rooftop boiler room - I was just anxious to get it hooked up to the antenna!? I might just as well bring it down to the apt and hook it up to the service monitor - unfortunately the rooftop that I have to cross to get to the boiler room is covered with snow and ice so I thought it safer to try from down here!? My service monitor, even at 1000mV into the TV antenna goes not get heard - but that is because I have an ampolifier in the line that has some attenuation below 50 MHz. I think a trip to the roof will be in order as soon as I get over this cold! Thanks again for your suggestions. 73 de Nigel ve3id

Re: Successful new install on raspberry pi but fails to calibrate
¿ªÔÆÌåÓýHello Nigel, Thanks for the screen shot! I'm not sure what the mountain in the middle is, but the I/Q calibration is used to remove "ghost" images mirrored around the VFO frequency. In your screen shot, it looks like the VFO is at 9995 KHz, with WWV at 10000 KHz (5 KHz above the VFO) ... looking for a mirror image of WWV at 9990 KHz (5 KHz below the VFO), I don't really see anything, which is good. OTOH, we may be seeing a mirror image of the 9980 KHz (15KHz
below the VFO) broadcast station at 10010 KHz (15 KHz above the
VFO).? Does changing the I/Q balance change the amplitude of this
(possible) image?? If so, that shows that I/Q balance is making a
difference.? If not, perhaps it is simply another signal. NOTE:? We may be able to see the (possible) 9980 mirror image much better than the WWV mirror image, because the? 9980 broadcast signal is about 20 dB above WWV's signal, and its (possible) mirror image is just about 20 dB above the noise floor.? WWV's mirror image might be just at or below the (somewhat stronger) noise floor at 9990, masking the image. Suggestion:? To avoid possible strange results from listening outside the intended range of the receiver, try finding one or more strong CW signals in the 40 meter band ... look for mirror images on the other side of the VFO ... it's easy to visually tell if it's a mirror of a CW signal, based on when the signal is keyed vs not ... you can even listen to the mirror image to listen for the same call sign, or CW tempo/style.? BTW, it's good to calibrate close to the frequency you are intending to use, as I/Q calibration can shift somewhat with frequency. Good luck! -- Ben, AC2YD -- On 11/22/22 15:24, Nigel Johnson MIEEE

Re: Extra bottomWidget line?
I want to thank Jim for making it easy to add a new widget, including the remote control messaging for it, in such a straightforward way.

Jim leveraged his recent work with MIDI, along with Quisk's widget infrastructure, to replace much of the less-elegant control messaging I had in my Remote Quisk proof-of-concept prototype, and it works great! Just a note of caution ... I'm not sure whether or not it's good to sleep for 2 seconds within your new OnTune() function ... Jim would need to comment on that, as he understands thread considerations much better than I do.? Same for Harald's recent question about blocking. -- Ben, AC2YD -- On 11/22/22 04:40, Niels Jalling wrote:

Re: Quisk Version 4.2.12 November 2022
Hello Jim,
Keeps getting better, LNA slider works as you have said and is the best solution. I have one bug to report which has been through several recent versions: The Config/TX Audio screen has no boxes to display the audio levels anymore. They were pretty handy for setting mic gain although it can be done just as well by using FDX and observing while making sure no clipping is happening in Pulse Audio Volume Control for PA but a little more care is needed for alsa. I don't know if it is a bug in the software or RF breakthrough but after a period of transmit the graphical display freezes on my remote. Everything else works fine and I can tune with the cursor moving but nothing else on the frozen graphical display. TX and RX are fully working and if I shut down the Ctl-Head and restart it all works fine again so the graphic channel had not stopped from the remote and VNC viewer also shows it running on remote when Ctl-Head is frozen. I'm reluctant to report this as a bug as it could be RF getting into my system but over the last 3 days I have put common mode chokes onto every ethernet cable at both ends and run the remote via wifi further eliminating RF into CAT-6 cables. Another thing that makes me think that it may not be RF is that it happens on all bands which I would not expect from RF breakthrough as it tends to be frequency independent. I would be interested to hear if any one else has experienced this issue. 73, Graeme ZL2APV |
Re: Successful new install on raspberry pi but fails to calibrate
¿ªÔÆÌåÓýOK, I will have to drag the service monitor up there, but will have to wait until the snow clears a bit!? I thought I could adjust it by tuning a carrier, of which there seems to be many.? I can get a good signal from WWV on 10MHz in? the evening, so the frequency calibration is spot on. Understand about the remote
- I am using VNC to access the headless node. Another thing is that Tony Parks sold me this as a 4-8 MHz RX ensemble, so I'm wondering how much of what I am seeing is images - certainly not WWV so I wonder if he shipped me a wider-band one by mistake. Not sure if attachments go through here but I will try - the 10MHz WWV signal is perfectly readable and the over-modulated signal at 9980 is a religious broadcaster. I assume that the mountain in the middle is what I am supposed to be getting rid of! 73 Nigel ve3id

Re: Quisk Version 4.2.12 November 2022
Hi Jim,
As I intend to use Qusik as panadapter, I set the VFO frequency in Quisk to 10.7 MHz. This works and is copied into the quisk_init.json as "VFO": 10700000. After a restart the frequency is back to 0 in the display (the audio button is used, as no AUX is available anymore in this version). Or is there another way to set Quisk into a fixed IF mode? (the former hardware files I created all set VFO to 10.7 MHz, but this does not seem to be copied anymore). 73s, Peter, PA3BIY |
Re: Successful new install on raspberry pi but fails to calibrate
Hello Nigel,
I tested on a local machine (no remote feature) with my RxTx Ensemble and everything seems to be working. When I inject a sine wave, the slider controls adjust the image to zero. And I don't see a frozen graph display. Note that you can not adjust the image from the control head in a remote setup. Adjust at the remote. If you still have problems, please describe more completely. And send any tracebacks. Jim N2ADR |
