Re: #sbitx - an ugprade kit is on the way
#sBitx
Ashhar,
We all accepted some risk inherent in a developer¡¯s edition. I imagine most of us would have been happy just to learn of the fix. To send upgrade kits free of charge was extraordinary. Thanks much!

Re: Connecting the sBitx Digital Audio Board to a x86 PC
For quite a while "just buy an HL2" wasn't an option. Another batch is finally available.
You would need to install an i2s interface in the PC and they seem to be shockingly expensive, why on earth would you want to do this ?
If you want to hook an SDR directly to your PC there are a plethora of SDR's which do this off the shelf, just buy an HL2.

Re: sBitx process no longer starts
John - try opening up the command prompt window, going into the sbitx directory, and starting the sbitx program directly from the command line ./sbitx
You may get an error?message or some other clue that will be useful in debugging the problem.

Hi Jim,
Yep, that is exactly the model Nextion I used. It will most likely come with a card telling you to download the latest editor software. I did that and re-compiled the .tft file, which seems to work, so I can send you that if it helps.
I¡¯ve got the components coming for the S-meter as well, so we can compare notes as we go - WhatsApp is fine for me.

Re: sBitx process no longer starts
I would guess the codec on the digiboard isn't responding, maybe pull the pi & digiboard and check the connectors, check of any signs of issues, if all looks good put back together and fire it up to see if it works.
I assume you are using Ashhar's image in an unmodified state correct ?

Re: Connecting the sBitx Digital Audio Board to a x86 PC
It has i2s pins and runs linux so in theory it should be possible to port the code with some adaptions. The China site seems to be out of stock though, a shame wouldn't mind buying one to play with.

Re: Daylight radio toroids
I don¡¯t think things are working the way they should OR I am not interpreting the data correctly. I really have not measured Q before with the NanoVNA. The micrometals? core showed a resonance of 13MHZ with a Q of 1000. The bird cage showed a resonance of 28MHZ with a Q in excess of 40,000. Those inductors were just from port1 to ground. Something does not add up:{ I used NanoVNA-saver and my SAA2 to get those figures. 73 K3BO Sent from for Windows ?

Hi Jonathan I am about to do the exact same thing and purchased this Nextion:
Which I basically pulled from the same youtube video.? There have been discussion threads about different versions of the Nextion and different versions of the CEC code so glad you had success.
Can you confirm if this is the Nextion you used?? I may want to separately Whatsapp you for details while doing this.? You possibly up for that?? I am also building in the same S meter referenced in the video as well. Thanks in Advance for any guidance. Jim K5KKB

There's no need for any metalwork on the case to fit the 2.8 screen, if you feel a bit brave: I followed the Youtube video from Lockdown Electronics:
I used my Dremel to gently widen the mounting holes on the Nextion board - it only requires 2-3mm each side - and then you can use the existing mounting stands & case holes. The screen centres nicely in the window and is fixed securely.

Executable File & User Settings
#sBitx
Hi Ashhar,
I would highly recommend that the "live" sbitx executable file, macro files, and user settings be moved out of the user¡¯s git directory and be placed elsewhere. I noticed the sbitx executable and user settings file makes pull requests become unmergable. This is easily fixable, but will be an ongoing issue. As I believe someone else mentioned, there are conflicts with the user settings file that is pushed via git pull and the user¡¯s settings file. Perhaps there should be a versioning method in the user setting file which the executable checks at runtime and informs the user if they need to update the user setting file from git. This will likely happen as new features which include new settings are added to the settings file.
I¡¯d be happy to work on the user settings file version functionality and also a script users could run (i.e. ¡°install¡± or ¡°update¡±) to place the executable and macros in another directory from their git directory, and give the option of keeping their existing user settings file, or overwriting or appending new settings from git.

Re: Funtronics uBitx digi interface installation in V6CeC
KK7BCO,? DISCLAIMER -? I'm not sure about the original stock firmware as all of my radios have been modded with Nextion displays and the KD8CEC firmware.?
All I have needed was a USB sound card dongle to my laptop to provide a mic and phone jack and a USB cable to the Nano on the Raduino.? If you are using a desktop PC the dongle probably wouldn't be needed.

Connecting the sBitx Digital Audio Board to a x86 PC
Hi all,
I'm trying to find a solution to remove the raspberry and use a PC connected to the sbitx digital audio board.
