I use these to help dissipate the excess heat. Slap them on back and let them do their job.?
Also use on Xeigu 6200.

What was your order number?

Ryan,
?
I'm sorry to hear that the zBitx arrived with a crack. I'm guessing the parcel had a rough journey to your location. Can you share some photos of the radio and the packaging with us. You can email it to us at support at HFSignals dot com.
?
I will share the STL files for the case soon.?

VFO Knob replacement for zBitx posted
Hello All,
I wanted a dimpled knob for the front of my zBitx, so I turned to Thingiverse to find a suitable knob and adjust the size to what I wanted and 3D printed my own in black PLA. The knob I've remixed is 10mm tall and 30mm in diameter, and will sit low to the front panel of the radio if you [very carefully] trim the length of the rotary encoder shaft. Please be careful to not bend the shaft of the encoder as you are doing this.
?
I've shared the files and full trimming instructions here

Re: Does zBitx have SWR display?
Ensure your software and firmware are at the latest versions. I also have found a power cycle helps with this.

Hi Farhan I loaded firmware 1.06 and I am very happy the chugging sound has gone from cw reception. This afternoon listening on ssb 20m I did notice some less pronounced chugging sounds. I will try and add this to the github bugs list. Thanks for the fast cw fix. 73 Nigel MW0NDE?
I have fixed the two issues of zbitx on CW. The new update has good keying with Iambic keyer and the cw decode noise is now gone as well. To get this update, you have to: 1. Flash the new firmware (the firmware version is now 1.06). The firmware is available from? 2. Update the new software on the raspberry pi, the latest version with the CW keyng fixed is 3.051 (or later). Here is Jose, VU2JOS sending CW with the new firmware update.
With this, I hope we have moved on with CW issues. - f ?

Re: Does zBitx have SWR display?
Mine doesn’t seem to do that. I’ve never seen a power output or SWR there.

When you TX, you'll see power and SWR:  This snapshot is from the manual, available here:

Re: Zbitx RPI SD-card image needed
Ragav
Thank you so very much !!
Now Im a happy bunny. unzipped and then flashed another 32Gbyte SD-card I had laying around.
Im using "Balena Etcher".?
Again - Im a bit concerned with the fact that the system is somewhat fragile. So I guess it makes sense to have the image available for download with instructions on how to flash if things go sideways out there.

Yeah I think the new software update is an improvement but some of the keying is still rough around the edges. It definitely helped with the chugging sound.
?
This issue remains unless it is unreachable code.? I posted this in the other thread about CW mode.

Changes/suggestions zBitX
1) does or could the transmit frequency show on the FT8 waterfall , currently only a red/orange line shows at the receive frequency. Maybe I am missing a setting?
?
2) Also on FT8, make the second “Call” button (F6) show on the display, I would edit the macro for “CQ POTA”. ?Now I have to access the keyboard to get to F6, a three step process. I use CQ, Call and CQ POTA often. I would suggest that REPEAT button could be lost, making it accessible only when connected to a HDMI display.?
?
Maybe there is a file that I could edit to accomplish this, any suggestions would be welcomed.

Just want to report I received my zbitx yesterday. ?It did have a crack in the side panel and there was something rattling inside. ?Took it apart the rtc battery was loose. ?Connected to my bench power supply at 8.5v and it booted fine. ?External monitor worked fine. ?Connected to the net time set just fine. ?I would not recommend this but I opened chromium and downloaded and installed nomachine. ?I figured it would freeze up due to lack of memory but went ok just a little slow. No machine remote is working fine. ?Listened to some ssb with it and opened fldigi for some decode went fine. ? Haven’t done any tx yet. ?Will test on a dummy load first. ?
?
Is there a file somewhere for the 3d case? ?I want to replace the broken side panel and probably change the color.

Sorry to be a stickler for detail here but, no, CW issues are not fixed.
CW operation has been improved but there are still timing issues. I'll be posting a video later today.

Re: Zbitx RPI SD-card image needed
you probably ran "sudo ./build sbitx" resulting in this problem. let us delete the sbitx file: sudo rm /home/pi/sbitx/sbitx and now, run? ./build sbitx
Here we go:
pi@sbitx:~ $ ls -l /home/pi/sbitx/sbitx*
-rwxr-xr-x 1 root root ? ? ? 0 Mar 31 04:40 /home/pi/sbitx/sbitx
-rwxr-xr-x 1 pi ? pi ? 1002132 Mar 19 04:54 /home/pi/sbitx/sbitx1
-rw-r--r-- 1 pi ? pi ? ? 42536 Mar 19 04:54 /home/pi/sbitx/sbitx.c
-rwxr-xr-x 1 pi ? pi ? ? 24576 Mar 19 04:54 /home/pi/sbitx/sbitx.db
I extended the "ls -l" slightly to see some more.
As you can see the "sbitx" is root/root but also empty...?
The other files are pi/pi... Does that ring a bell ??

Re: Zbitx orders might close soon
We are trying to get some ex-hfsigs peeps who retired from work to?help us out. it would be good get the band back together. If that works out, we may not have to suspend sales. keeping fingers crossed...

Re: Zbitx RPI SD-card image needed
Hello Sam,
?
The file is stored in a zip file.? Try extracting the image and creating a microSD card with the extracted file after you rename it to remove the extra .img at the end.
?
It should be "zBitx_image.img" without the quotes.
?
This image may not fit on some 32 GB microSD cards.? I use 64 GB cards to ensure that the image will fit.
