Hello All,
?
I'm new to Linux so I have a quick couple of questions, On line #5 of Ashhar's install.txt, of the new Sbitx 2.0 software, in Github. Do I have to put "SBITX Audio? ? ? ? ? ? ? ?WSJT-X Audio" just as it appears on the command line? Do I put "WSJT-X Audio", with all the spaces before it, on the command line also?
?
Question number 2, on line #5, below the above line, do I have to place the arrows as they appear , ¡°hw:1,0 -> Line out ----> hw:1,1 Mic In / Capture¡±, with all the dashes on the command line also?
?
Question number 3, last question I promise. Do I use the Sbitx's radio command line to place all the commands on or do I use another program on my computer? Thanks for all of your patience. I really appreciate it..
?
Thanks Again,
Robert, AG6LK

Re: sBitx V2 HTML audio latency
Yes, these apis are inconsistently implemented across the browsers. The API that we are currently using is not meant for live audio. Hence, its real time performance is suboptimal. If we ca measure how many samples are already in the queue, we can make this much more live.? The webrtc, unfortunately only works with a website that has an ssl certificate. I think we should look for solutions that work without needing the internet. Lets see if we have any other way to do this. Going the app way is too painful. We will have to write at least five apps : windows, mac, linux, androie, ios. HTML is the way to go, I think. - f
I thought that the latency was a Safari issue.
As far as the API, I notice a flush function in pcm-player.js

Re: sBitx V2 HTML audio latency
Mark, As I had mentioned?before, this is sn early stab at audio. The audio is using websocket instead of udp.? However, even with websocket, it doesn't have to be so bad. The culprit is that the safari is buffering the audio samples inside its engine. It is much better with chrome. The delay is under a second. We need a way to measure the buffer size. If the buffer gets too big, dump it and start over. I am not sure what the api for this is. It is somewhere in the labyrinth of all multimedia apis. - f
The Safari Browser on a Mac Mini M1 has a latency problem with audio from sBitx V2.
The spectrum and waterfall appear to be in real time, but the audio is delayed. For example, when people are talking on SSB you see a burst of activity on the spectrum and waterfall and then you hear the audio.? If you turn on the audio on the sBitx speaker, that audio is in sync.
To get a handle on the latency, I started listening to a time standard station (WWV) and compared the start of the minute tick with another clock set to UTC.
For the first test, the audio on the Mac was 9 seconds behind (the top of minute beep occurred when my clock said 9 seconds past).
I closed the Safari window (but not Safari) and repeated the test. This time the audio was 17 seconds behind.
I closed the Safari window (but not Safari) and repeated the test. This time the audio was 27.5 seconds behind.
I shut down Safari and opened a window. This time the audio was 4 seconds behind.
I did the same test with Edge on Windows 10 and the audio was within a second.
After some time doing other things (but the sBitx was running the whole time), I repeated the test with Safari. This time the audio was 24 seconds behind.
I listened to a net for half an hour and the audio played fine, it was just delayed. But there were no jumps in the audio. Apparently, the entire latency is being buffered somewhere.
FWIW, I tried accessing sBitx from Safari on my iPad. The app runs fine and responds to user input, but there is no audio and no activity on the spectrum/waterfall.? I don't whether some privacy protection is blocking those streams.

Re: Sbitx v2 Function Knob
Gyula, ? Yes I did see that on the video. However it still doesn¡¯t work. If I leave the graphical display mode and push in the knob it shifts to the audio square, highlighted, on the right side of the display and still unable to adjust vol with knob ? 73 Art N2AJO ?

Re: Sbitx v2 Function Knob
the videos show that you press it in first, then roll it.

The function know on the upper right isnt working. I can change vol & rf by dragging but unable to get the knob to work. I can change the color on "VOL" from blue to white but the knob doesnt work. Looking for guidance

pictures and videos of sbitx v2
The sbitxs have started to arrive. Can the operators send us pictures of working the radios? There maybe some hiccups in the way it works. As a programmer, one gets biased to the way the code is written and sees nothing unintuitive about the implementation. This is not the way end users perceive?it.? While we imagine sbitx is simple, users may find some parts perplexing. These are usability bugs and need to be fixed. Very often, we live with such "features", with sbitx that not longer a restriction with is ability to update with a few keystrokes. - f

I have been looking for a 18650 power supply for my UBITX and finding a supply of 18650 from various battery packs with bad wires, management boards etc. I did not want to mess with the spot welding on used batteries. I found this at Parts Express. everything I want? DC in 5-24 VDC in for charging, a solar input up to 19v a relative battery charge indicator, and other outputs. Also replaceable battery holders.? ?The only thing I need to figure out is it needs a temporary charge volt to start the circuit. Small problem. Take a look at it. 73 KG4VHV john

Sbitx-V2 + winlink HF + FLdigi>Mt63?
Farhan,
What would it take to interface the above with the new V2?

Yes, unfortunately. We have asked DHL for clarification but we haven't received anything yet.

Re: sBitx original GUI CW input device with V2 software
It is like any other touch screen, a la iphone/android. We have cramped up too many controls, taking up any draggable real estate from the display area. I dont know what we can take out from the screen. Feel free to customize the index.html file in the web folder. - f
Ashar,
No, I didn't know that that was a feature.?
It does make operating with the touchscreen easier.

Hi all,
the same here. I paid 30% extra cost from total cost of package for VAT+DHL custom clearance fee. There is no chance to help or change it I guess. There was no TAX cause of ham radio gear but somebody need to pay the VAT when it is coming to EU¡
So even although I paid additionally 140€! ¡I wanted the radio so I accepted it.?
I don¡¯t think that Farhan or HFSigs team can do something in this case. ?

Hi Ashhar and group
For sBITX W/o Raspberry I just pay 97 € VAT and DHL fee? Its "fine", no customs tax I suppose is because its a kit.
Since July? 2021 in France with E Sales we have to pay VAT from the first Euro!!
?There is nothing to do unfortunatly
Thnaks for the job!

With the regulatory environment in the EU, producing the sBITX there would likely not reduce the costs in any meaningful way.? Paying duties, etc. on the parts you would need to import would also add to costs.? It is also doubtful that PCB manufacturing would be as reasonable.
