Confirming the farhandev branch does fix the issue. Thanks!?

I have an implementation to fix this. It is in the dev branch on the git
For the CW operators here ... have you had any problems with the sBitx CW keyer?
The timing seems off for me when keying at higher speeds, and the TX isn't quite right even using an external keyer. I took a couple of videos showing what I mean:?
Using an external keyer at 25 wpm, the dits are much more staccato than they should be and sometimes entirely cut off. The TX is bad enough that the RBN will not pick up my call when using the external keyer:
Using the sBitx internal keyer at 25 wpm, there are many keying mistakes introduced by the software, for example when keying the word "POTA", which is a word many of us will be keying of course:?
Keying using a small keyboard or a save message seems to work fine, so that's good :)?
I noticed the code polls the GPIO associated with the key only about 10-20 times per second, which I think is much too slow for faster keying, so I was thinking about rewriting it to use GPIO interrupts to change the CW flags instead of repeatedly polling the GPIO.
Does anyone have thoughts on this as a possible approach??
Thanks,?

Re: Time zone not changing?
HF Signals uses the name/password pi/hf12345, which you can change to anything in RPi Config, just don't forget it ;-)

Re: Time zone not changing?
Hi Gyula,
Thnak you and thank you for all and any help.
Just thought is the user name "pi"?
I bought the sBitX v3 directly from HF Signaals fully assembled, tested, configured and calibrated.
When I first powered on it didn't ask for a user or password nor did it ask to change anything, so not sure what has happened.
I will search how to restore the image which I am glad a made a backup of.

Re: Time zone not changing?
Ray,
I'm just a user and I'm sorry that you have so much trouble with this setting.
If it doesn't accept pwd (default hf12345), then I have to ask if you bought the RPi4 together with the device or separately. If you bought it separately, you should not use this id and pwd (in this case pi and raspberry).

does the pi4 operating system that comes with the sbitx v3 support booting from the usb port? can it be set to do that without opening the case?? tnx Don w8ptb

Re: sBITX 64Bit Pi Image Available

All -?
I fixed the scope display for CW mode today. The frequencies are back!
To update your system..
open terminal
type cd sbitx
type ./update

Re: Learning/fixing PSK31
I've been taking a look at the CW keyer, which is also kind of broken in that it doesn't really work at higher speed keying with a paddle or a straight key.? One thing indicated in a comment in the cw modem specifically is the `modem_poll` function (in modems.c) is called about 10-20 times per second, which to me seems too slow for high speed (20-25 wpm+) CW keying. The same function also appears to manage PSK31 transmission, but I don't know enough about PSK31 to understand whether 10-20 seconds is fast enough, or whether the problem might be elsewhere. It might be somewhere to start, just not sure.? Apart from this, there is a comment at the top of the modems.c file that explains how the digital modems work:?
/*
This file implements modems for :
Fldigi: We use fldigi as a proxy for all the modems that it implements
?
?
General:
?
There are three functions called to implement almost all the digital modes
1. There is the modem_init() that is used to initialize all the different modems.
2. The modem_poll() is called about 10 times a second to check if any transmit/receiver
changeover is needed, etc.
3. On receive, each time a block of samples is received, modem_rx() is called and?
it despatches the block of samples to the currently selected modem.?
The demodulators call write_console() to call the routines to display the decoded text.
4. During transmit, modem_next_sample() is repeatedly called by the sdr to accumulate
samples. In turn the sample generation routines call get_tx_data_byte() to read the next
text/ascii byte to encode.
?

Good luck!

Re: Time zone not changing?
Hi Gyula,
I did the file edit for the timezone e.g. removing reference to Arizona, saved, then rebooted but now it is asking for a password.
I have tried:
123
1234
12345
hf12345
hf
hf1234
hf123
etc
So at the moment it is a 'pretty' decorative desk item!
As for grid reference, I enter:
\MYGRID IO93GT but it shows "NOWHER", there is a screenshot in my recent post.
However, all this is academic until I can logon back in, might be a restore from the disk image, glad I made that on Raj suggestion!

Re: Time zone not changing?
Thank you Gyula.
I changed my settings to UK and Europe/London GMT (UTC) or thought I did.
And thank you for the document link.

Re: Learning/fixing PSK31
It sounds like you are light years?ahead of me in programming! I hope you are successful,? not sure what the issue is, but I know there are some here who can collaborate with you on that.?
Scotty WD4PYT?
I am a new owner of the sbitx v3. Already really enjoying it. I got the radio to learn and grow my knowledge of digital protocols specifically.
I see that the native PSK31 mode is broken. I'd like to try and fix it in order to learn better how the sbitx software is built. Does anyone have any pointers on why its currently broken? I imagine the modem parts are fine since it relies on fldigi, so is it likely the interaction with the gtk app ? Maybe I fix it maybe I don't but I hope to learn either way. Thanks in advance.

Re: sd card replace sbitx
Hello Ray. Who did you purchase your's from?
73 Frank
What booklet?
My sBitX v3 was preassembled and calibrated, came with a 'hello' letter, sheet with all the 'parameter's' and an invoice sheet.
That is a great link, thank you.
I think they should included more information with preassembled units, not all of us are hackers, tinkerers or coders, for one reason or another but like using radios.

Want to have a Homebrew-to-Homebrew QSO?
I make POTA Activation attempts on 20M Phone occasionally, and it would be nice to make a contact with any form of BITX? or other homebrew-type rig, which I have never done before? except on CW.?? If any of you are interested, please send me an email 72, Walter KA4KXX Orlando, FL
