Re: sBITX V2 TX no output
OK, I think that might be the original V2 software
OK, I think that might be the original V2 software
Can you check each mode, single side band, two-tone, and CW (press the key down, ) and check that you have output, ?& what it looks like on the screen?
If at least you can get that software working you have a working radio.

Re: Brainstorming: sbitx with new Raspberry Pi 5?
#sBitx
Hi Ashhar,
People have different needs, so the faster CPU and GPU would be helpful to some, especially for DSP and media intensive tasks, eg, for vocoders based on ML. Also, the I/O is very improved, while PCIe on it is very good for NVMe usage. I like to play smoke on the water!
: )
Anyway, do you know the limits of the regulator that feeds the Pi? I can just set the cpu governor to keep the clocks low anyway.

There will be little gain, really. The sbitx works just?fine even on the rpi zero 2w.
If you find it radio sluggish, what you need is more RAM, mostly for the web and other software.

I’ll agree with Discord being a good path / option. It is very hard to find things in an email repository with so many emails in it.?
As a new user (soon to be) of the SbitX, trying to get a handle on what is happening is very difficult. ?Separating out by channel would allow new owners to focus on specific topics such as software updates, using the UI, hardware changes, etc.?
Just my opinion. ?Oh, Discord has been very useful in the 3D printing world. ?

Re: v3 software, alpha is here
The way cw decode works is like this: 1. Switch to a span of 6k or less. 2. Set the bandwidth to 400 hz or less 3. Tune the signal to be right on top of the pitch line in the middle of the passband. 4. Nudge the wpm control to approximately the speed of the signal. You can be off by a wide margin. But you have to nudge it for it to decode, I am not sure why. - f
Hi Gyula
I think v3 alpha is a fantastic step forward, and I do appresiate the hard work Farhan and others have invested!
That said, I think this is an open forum where we also can discuss the shortcomings with a joint ambition to make the software as good as possible.?
Hope to hear others experiences with SSB and CW decoding, and hopefully learn from it.

I have used a TDK-Lambda LS75-12 for several years without problems.? It is switch mode but meets EMC standards to Class B, the tougher limits for residential use.? I have not noticed any RF interference from 80 metres to 70MHz (UK 4 metre band).
It is available from Digikey.? I mostly draw a max of 4 amps on trnamit, and on receive the power supply is very much underrun, which should keep it cool and reliable.

Re: v3 software, manually entering LOG does not work
When you call cq, with auto on, it picks the first responder and completes the qso. With auto off, you have to chose who to respond to.

Because there is no visible change.
I know, the programmer has enough problems.
The user wants to know which button performs which action.
So we just guess how it works, even if we have some knowledge of another program.

I don't think moving the conversation to Discord is a good idea because the group on groups.io is searchable via public search engines which is beneficial to all. Discord is a closed system and I'd hate to see fragmented information in multiple places.

Hello Pierre, The sbitx program first tries to read hw_settings.ini.? That is the file used by the program.? If hw_settings.ini is not found, it goes to hw_settins_default.ini and prints a message to the starting process.? It is up to the user to either rename or better to copy the correct file to hw_settings.ini. With a DE version and not adding the SWR/Power sensor, I copied my calibrated hw_settings.ini from my V2 folder. Here is the code in the sbitx.c file:
static void read_hw_ini(){
hw_init_index = 0;
char directory[PATH_MAX];
char *path = getenv("HOME");
strcpy(directory, path);
strcat(directory, "/sbitx/data/hw_settings.ini");
? if (ini_parse(directory, hw_settings_handler, NULL)<0){
? ? printf("Unable to load ~/sbitx/data/hw_settings.ini\nLoading default_hw_settings.ini instead\n");
strcpy(directory, path);
strcat(directory, "/sbitx/data/default_hw_settings.ini");
? ini_parse(directory, hw_settings_handler, NULL);
? }
}

Re: v3 software, manually entering LOG does not work
Barry, If you turn on the AUTO it latches onto the first response to your CQ. Often, someone tailgates the first call and the second call continues automatically. I have watched it sometimes run for 15-20 minutes, "running" calls one after the other without my intervention (ugh!). I am hoping nobody rights a javascript to pick and qso the entire dxcc list automatically. At that time, I will fire up my BC348 and 6L6 and retire to a cave. - f

Re: Quick question about the RTC

I'm lost here. I dont?have a "sync" button on my radio. Is this is another program? I am using the native system built in by Ashhar and not the others.

So FT8 has to be really accurate to work like it should and the sBitx V2 have the RTC in it and I am guessing for this reason. I have gotten a couple of emails from people saying the time is off by 1 second or maybe a little more and I was wondering how does the sBitx set the time and how long can I expect it to hold that time without internet connected? I am under the impression that the RTC is super precise and I want to know how long can I trust it to use FT8? That's all.?
Thanks for the help Ashhar, I am really loving the radio and look forward to learning how to install v3 at some point.
