Has anyone published a fix for this exact issue as yet?
Vince,
it seems like the problem is unknown to others.
I think this might be a unique thing. (has anyone else had this problem?)
When I first read about it, I thought it was a problem with the time displayed by various applications, but then I realized that it was something else.
I certainly wouldn't leave it alone, and no one else reported it, so you have to solve the problem yourself.
Have you created a new Image and set up everything from scratch?
In my previous message I referred to the Files folder, please take a look at what needs to be set up to use the new Image.
I don't know what is on the released Image, I just assume that the necessary applications are also on it, so they need to be customized.
Expect these devices to be like a precious egg, and always make backups of either the full Image (SD Card Copier) or the daily variables.
I have a USB stick ready and before I turn it off, I copy the daily changes to it.
It may happen that the next time you turn it on and the OS cannot recover, in this case you need the Image backup and the USB stick to be able to replace the changes.
This backup/Restore thing is important here because the many different settings take up a lot of time from your life, don't waste it on this.
It could also be an SD card quality problem.
I use sBitx v2 with the modifications that are important to me.

Re: FT8 time differential - how to resolve?
I do save directly to CQRLOG via udp. Wsjt-z/wsjtx write to the wsjtx_log.adi file also. CQRLOG does not post to which I also use, so I use the wsjtx_log.adi to import transactions into my logbook because it has only a few entries whereas my cqrlog logbook has over 62,000 records in it.
Leo, AI5II
Leo,
If I understand correctly, you don't save the QSO data directly to the cqrlog, but you copy the wjstx_log.adi file. I don't understand why, when you can save the data directly to the cqrlog when the QSO is finished, it stores it in the wsjtx_log.adi file as well. I also like to use the cqrlog because I can see the QSOs together and upload or download them to servers either automatically or manually. You can read the install and settings data in a pdf file if you don't do it that way. Since I made several guides during use, you can find them in the Files folder by clicking Updated twice in a row, it is visible for the latest upload.

Re: FT8 time differential - how to resolve?
If you open up a terminal and cd to '/' and issue this command 'sudo find . -name wsjtx' you will see that there are multiple versions. The wsjtx.desktop is pointing to the wrong one based on your $PATH. So you have both the original version of wsjtx and and wsjt-z on your system but to? run either one you issue the same command, wsjtx. The one that gets executed is the version that is found first. There are also multiple versions of wsjtx.desktop. If the desktop icon did not change when you installed wsjt-z then the wsjtx.desktop file is pointing to wsjtx not wsjt-z. You installed wsjt-z into the PREFIX=/usr/local folder so wsjt-z should show up as being in '/usr/local/bin' having the path of '/usr/local/bin/wsjtx'. The first thing I would try is to rename the wsjtx.desktop file that appears on your desktop and then? 'cp ~/build/wsjt/wsjtx.desktop ~/Desktop'. Now see if wsjt-z runs when you execute the new wsjtx.desktop file. If it does then all is ok. If the old version still runs then the issue is with your $PATH. I always install MY stuff into '/usr/local' and I want the system? to find my installed programs first,? but the search sequence finds the old version first so that is what gets executed . There are a couple of ways you can deal with this. The easiest I've found that works for me is to modify the $PATH in my .profile file to make sure that? the '/usr/local' directory appears before the directory that the old version of wsjtx is located. If you run 'echo $PATH' you'll see the search sequence. PI's .profile file is located pi's home directory. Just 'cd ~'? and 'sudo nano .profile' to edit it. Another that I currently am using is because I run CQRLOG, is to start wsjt-z from cqrlog which you can do in the preferences because you can specify the path to wsjtx as being /usr/local/bin/wsjtx' to start wsjt-z. If you leave that path blank? then CQRLOG would start the old version of wsjtx.? A way for you to see what is going on is to open a terminal and issue the command wsjtx. You'll probably get the old version. If you issue the command '/usr/local/bin/wsjtx', you'll get wsjt-z. The other thing that I have found is that if you decide to run cqrlog as your logger that cqrlog sometimes? has a hard time finding the wsjtx_log.adi file. So what I do is cd to the '~/.local/share/WSJT-X' directory and if the wsjtx_log.adi is present, I copy it to the '~/Desktop' directory, delete the wsjtx_log.adi file and create a symbolic link to the desktop file with this command : 'sudo ln -s ~/Desktop/wsjtx_log.adi wsjtx_log.adi'. A side benefit to this is if I want to import that adi file into or another logger, I have easy access to it? Hopefully this is not confusing you and it helps.

Re: sBitx V3 64 bit has new noise problem
Did you put a ferrite choke on the I2C cable? Also make sure that you post this on the Discord server so the original developers (us) can assist.

That would indicate that there isn't enough amps provided in the PD cable.? That is a common issue when there isn't enough power/amps to provide the tx and the raspberry pi's
I¡¯m using a PD power supply that comes with my MacBook computer along with a 9v trigger cable rated at 5 amps. But I cannot set Drive beyond 60 with FT8 on 20 meters. If is over 60, the zBitx restarts when transmitting . I don¡¯t know it¡¯s the trigger cable or the PD voltage drop.

Re: zbitx - WiFi question
That?is correct, setup the wifi first(home / phone) and then afterwards when you boot the zbitx it will autoconnect. No need for it to be connected to the monitor/keyboard/mouse.

zBitx - red line in FT-8 spectrum display
Just got my new zbitx and I love it. Have only run FT8 so far. I have some questions.?
Is the vertical red line in the FT-8 spectrum display not the TX tone? I select PITCH and turn the knob. The number in the box changes, but the red line doesn¡¯t move. How then does one avoid being underneath the strongest signals?

zBitx - selecting in FT8 (responding to CQ)
Just got my new zbitx and I love it. Have only run FT8 so far. I have some questions.?
The manual says to answer a CQ, select that line and press the knob once. Doesn¡¯t say HOW to select. From other discussions here, apparently tapping in the decode list then rotating the knob. OK, I did that then pressed the knob. Nothing.?

Re: FT8 time differential - how to resolve?
Vince,
So if I understand the issue correctly, the zBitx goes into TX mode when it is supposed to (0, 15, 30, or 45 seconds after the minute, but RF isn't transmitted until 1.8 seconds later, correct? Or does the zBitx go into transmit mode 1.8 seconds after it is supposed to.
By 'transmit mode' I mean the GUI indicates it is in TX mode.

Time Zone is not the issue. I have commented out the one line in .profile that forced the TZ to Arizona and rebooted, and now it shows proper TZ. Thank you for this comment on what to do, but note that the sBitx manual states this, not the zBitx. ?
Clock Drift is not an issue for my radio. My clock is DEAD ON accurate.
?
The issue is that the FT8 client delays when you hit the transmit up to almost 2 seconds - and it does this right away after boot. It is consistent in this amount, so clock drift isn't an issue like Joe is seeing.? SO to me this is something with in the FT8 client and how it transmits. Best described as "press CQ, wait for the clock to hit the next transmit interval (0, 15, 30, or 45 seconds), count to two seconds and then the TX engages.

At the other end it looks like this:

sBitx V3 64 bit has new noise problem
I am getting this band noise. It has not always been present. Could this be caused by the INA260 voltage/current sensor module I recently added? I¡¯m asking to see if I need to remove it from my radio. I am hoping this has been discovered and fixed by someone else already. Has anyone else seen this yet?
Thanks?for your help in advance, David WK4DS?

zBITX working fine - Test Report attached
Hi, There have been few reports on this list of customers' zBITX units arriving with issues.
Mine arrived in fine condition here in?Australia via DHL courier.? Standard packaging seems ok, with little chance for damage if treated properly.
If we were to assume nothing being equal, we might be able to trace the issue starting from final "Test Report" before shipping to testing after unboxing.
When I received my unit, I placed a couple of batteries in the holder, attached a dummy load, and tested it briefly using another transceiver.? All seemed OK.
I do not know how useful it would be, but I am attaching a photo of my test report below in case that helps.? I am wondering if those that have issues with their units want to do the same in case it might help discern a pattern.
I am basically a software guy, and am looking forward to buying?another unit to test them together with each other,
Best regards,
-Rob, VK4SSE

So I was playing with getting some of the display noise out of the receiver today.? I used metal standoffs to ground the lower board to the backplane, then an extension cable to the display, next I was power the display with a separate power supply.? Lead popped off and landed on the pi zero. Display would no longer update.
?
Hooked up HDMI and it threw a bunch of coms errors, no receive, and the pi is getting hot.
?
I figure the Pi is done. And maybe anything hooked to the I2C buss.? Thought I would order the rtc and si5351m shown in the schematic too. But mine has a ms5351m instead, which is normally in the zbitx???

In the event that ?needed to return the zBitx to HH Signals and receive a refund how easy is the process and who pays for shipping ?
