Re: Zbitx power cord connector
This is unfortunate. We actually ordered a die to be made for this connector! On Thu, Apr 3, 2025, 8:01 AM Matt via <rehash_dolor_0b=[email protected]> wrote:

Re: Waiting for the zBitx to start…
In addition to the uSD card, you need to buy a uSD card reader, which can be read via USB and written with a writing program.
Make sure that the USB can be connected to both the PC and zbitx. To the PC when you download the Image, to zbitx when you want to make a backup.
Since the published Image is in .zip format, you have to unpack it first, which is 32GB in size here.
It may happen that during production, the 32 GB SD card cannot be written to, because the new card is a few bytes smaller than the Image.
That is why you may have to buy a 64 GB card.
If the creator of the Image is more skilled, he will remove the empty part of the card using the shrink method, and the Image could be much smaller.
It is advisable to buy a good quality uSD card, which can also be used for Backup.
Don't worry, if you insert a 64GB uSD into the device, you can copy it to a smaller size than Backup using Raspberry->Menu->Accessories->SD Card Copier. It is advisable to make a Backup, if you have successfully set the .ini files, you can use the Backup to restore in case of an error.

zBITx Power Plug Intermittant
The only thing Which jumped out at me was a highly intermittent power cable between the batteries and the unit which was supplied by HF Signals. Rotate the connector or barely touch the cable and it would recycle power. I replaced it with a new 5.5mm outer barrel and 2.1mm inner barrel cable and it now works fine and is very stable.
?
The new cable has a full 360 degree "tube/barrel" to make GOOD contact with the center pin in the female connector,?the original does not....take a look at it.?
?
Great Little Radio?

Re: Waiting for the zBitx to start…
开云体育Unfortunately, not yet. I'll follow Jeff's advice tomorrow and buy an SD card and research how to transfer the data to the SD card via PC. I haven't done anything like that before. I'm still clueless and hope it will work. I'm not a computer expert.vy73, Frank? Am 03.04.2025 um 20:54 schrieb wa6ara via groups.io <wa6ara@...>:

? On the sBITX, the shut down button in JJ's sbitx code is in menu 2. There is no need to open the toolbox.
? On the zBITX, unless you have an external monitor, there is no way to get to a Linux window. The zBitx display is controlled by the Pi Pico run by the zBitx app on the Pi Zero. A useful shut down function would have to be part of the zbitx code.

Re: CW on zbitx
I updated my Zbitx yesterday (Wednesday) to 3.051 and 1.06. Yes it fixed a couple issues but CW remained unusable. So today (Thursday) I decided to update again, thinking I might have gotten an earlier Raspberry pi copy.
Now I have bricked the radio... No boot up of the Pi ( screen is ok). With an external monitor the Pi doesn't go past the first steps of booting, freezes and ignores keyboard and mouse.
?
It stops at the following:

Re: CW on zbitx
开云体育?Line 4527: ?modem poll is only being called every 20th tick Modem_poll , then calls cw_poll -but this cannot happen any faster than every 20th tick with the current code It is actually CW_POLL that really causes transmit to occur. But this cannot start any faster than every 20th tick because of the way the routines ?are being called. It is easy enough to prove us wrong. Simply change the calls to modem pole to occur every fourth tick (instead of every 20th tick ) and if it doesn’t get a lot better than we’re wrong. Wishing you the best!

I do not yet have my zBitx setup, so I can not test using a macro to call JJ's shutdown script in the toolbox.? The macro button, like the logging function buttons, could be available on all screens.

Re: CW on zbitx
Farhan,
?
The issue is most likely caused by poling the state of the key 96000 times a second and only acting upon it in modem poll 10 times per second. The solution in the 64-bit branch was to adjust modem_poll to check multiple times in each call.? The transition states are being made but not acted upon.
?
From modem_pol()
?
/*
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.
?

I need to look at the details more to verify that the comment is accurate.

Please provide a link. Please see the manual. You can export the log into adif. It is on the hdmi /gtk user interface On Thu, Apr 3, 2025 at 1:29?PM Ashhar Farhan via <farhanbox=[email protected]> wrote:

Re: Just ordered by ZBitX
开云体育
Geeze.. so sry I am slow to really look at the pics.. I don't really see frame damage..?
And I see the ref output on the rear panel.. guess this model didn't have the front connector for ref?
IF the reference works on the rear connector, would you take $275?
thanks for your patience.

Re: CW on zbitx
I am not making myself clear. The cw_poll nor modem_poll has any use of reading the keyer.

Re: Waiting for the zBitx to start…
开云体育Until someone can help you...I’m no expert. If I was in your situation, I would probably get another SD card. Download the image, burn a new SD card and put that into the radio to give it a try.?
You would still have the original SD card available if needed.. |
