Re: Latency constraints for remote operation?
Thanks for clarifying ... and that is pretty consistent with my
experience, using Quisk over network *or* just locally (no remote
feature) ... I'm pretty sure this could vary some from computer to
computer, and sound system to sound system, although with remote
usage, the sound system buffer needs to additionally make up for
any network jitter (but not average network latency) ... I have my
Control Head Play Latency set at 30msec on a pretty fast Windows
computer with WiFi connection to my local outdoor rig-in-a-box,
which gives me an occasional crackle, but is mostly fine ... I
used it all weekend in the CQWWDXCW contest (and it's amazing what
5 watts can do!? 400+ Qs in 78 different countries from East Coast
USA).

Re: Latency constraints for remote operation?
Thanks for the good report!? Glad things are working for you.
Which "buffer delay" do you mean?

Re: Latency constraints for remote operation?
Hi Ben et al,
So there are several (UDP) ports open at 4G in the Netherlands. Among them UDP port 1194, which is used by openvpn. Over the past days I installed openvpn as a server on the odroid XU4 on which I also run Quisk. The client part of openvpn was installed on the control head of another Odroid XU4. And now magic: It runs over a MiFi link! Using only 20 ms buffer delay I can still not notice hick-ups, and the data consumption is roughly 56 kB (Bytes!) up and 38 kB down, so about 500 kbps of total data bandwidth usage. My round trip (ping) delay time to the MiFi is less than 50 ms, 32 ms average.
So I am quite happy so far!
73s,
Peter, PA3BIY

Re: Latency constraints for remote operation?
Hi Ben,
I've found the reason why I can't connect over a MiFi: limited port access. The 4G providers here make only very few ports available (open), hence I will have to use some kind of tunnel. Initially I tried SSH tunneling, which worked but with a 10 s update timing of the graph :-(. So now I am in the process installing Openvpn, and will use port 1194 (UDP), as that port is open over 4G. I am not there yet, configuring openvpn takes more time than anticipated, but I will let you know when/if I succeed.
73s,
Peter

Re: Latency constraints for remote operation?
Hello Peter,
Are you using the latest Quisk?? I recently did some work on the network connection aspects (especially the "already in progress" issue); Jim released that work in the latest, 4.2.12.
If you are already using 4.2.12 (or even if not), try starting the Remote Radio Quisk (making it available to connect) before starting the Control Head Quisk.

Yes, PW is set on both devices. The remote and local are both sitting on my desk, so initially I connected them to the LAN, and it worked. Next I connected the Remote to the MIFI and set the appropriate forwarding ("virtual servers").
There is 1 error on the Control Head:
Remote Control socket.connect() error: [Errno 114] Operation already in progress
There might be another issue: Blocked port ranges by my 4G Provider (T-Mobile). I ran into that a couple of years ago, but have not found a list (yet) of blocked ports. That's if T-Mobile is still blocking some ports....

Re: Latency constraints for remote operation?
Hi Ben,
It seems that all my ports are closed, in spite of the port forwarding. At least that explains why it does not work, not the "Why" they are closed.

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....

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.

Re: Extra bottomWidget line?
Quisk runs with two threads, a GUI thread and a sound thread. You must not sleep() in the sound thread, as this thread is time critical. If you pause in the GUI thread, you run the risk of freezing the GUI interface. But this may be acceptable for short periods.
