ZBitx hangs on startup
5
ZBitx hangs on startup TC Tom Crowley ? To:[email protected]? Thu 3/27/2025 16:30 Ashhar, with a monitor, keyboard and mouse plugged in. The zBitx screen image remains the same (no change during boot-up). The monitor shows a normal startup with a window showing what may be an issue. Rebooted the machine and the zBitx window did not change, however the monitor showed a normal reboot. Unable to kill the zBitx program using the normal tools.

sbitx v3 no output after upgrading to 64bit
3
Hi eveyone. I have been trying for the last couple weeks to upgrade to the 64 bit software. On the 32 bit, output is about 17.5 watts but when I swap to the 64 bit I get very little to none as far as output (my watt meter doesn't even register). I have redownloaded, reimaged multiple times and still can't get any output. I can reimage to the 32 bit image and everthing works correctly on transmit. What am I missing here? The 64 bit works much better in every way except the transmit.

zBitx DOA
13
Good morning My zBitx arrive DOA. I sent a message HFSIGNALS but got no response. It will not power up with the connector in place. I used my multimeter to test the power on the connector from the fully charged batteries and it is 8.33v, so the power source is good. The radio will not come on. I can bring up the screen with the CAT port so that is all. I think I need to exchange it. How do I get that started. This is very disappointing https://youtu.be/I2fcVvsSaQQ?si=KRBCrjFCZKEzHMk- Mike,, N4GW

zBitX radio hanging randomly.
16
First thing to note is the firmware is 1.02. I'm unsure how to upgrade it, but I saw there was a topic on it, so I'll try that. Second thing to note is that most of the interface chrome is working most of the time. My issue is that the radio just stops working. Audio stops, the waterfall stops, the decode window stops. Nothing besides a reboot helps. It seems to be caused by raising the frequency. I have it on 7.046.330, and I'm trying to tune up to 7.047.5, to try and tune in W1AW. I have a strong signal in the right third of the waterfall, and it doesn't stop to let replies go, so I'm thinking this may be W1AW. The decoder is not decoding it properly. I'm not sure why W1AW would be so offset, but it seems about 700hz low. Is that a factor of the offset affecting the frequency of the station? That seems odd to me. For some reason, the radio portion would just stop. I've tried to adjust it more slowly, in case loading of the processor was too much for it, but I don't know that it was having that effect. I've got a decent signal at 7.052 that is decoding well. It's a slower signal, around 12-15wpm, but that's good, because I can follow along in my head for some of it. Once in a while I hear the station in Texas he's talking to. I'm not sure where he is. But now it seems to be working. I need to update my time in this lovely beast, but am totally unsure how. It doesn't have a GPS. I'll have to see if I can find one and figure out how to get the value into the radio. Until then, my FT8 just isn't decoding anything. I hope a manual will be out sometime soon, I'm one of THOSE who needs to read the fancy manual! Gwen NG3P

Yahoo. Getting close. I happened to check the status(link was provided in your email order confirmation ) of my order and saw that it's packed and ready to go.

What seems to be the most practical external microphone for the Zbitx? Thinking about one for POTA or SOTA.

The Pi zBitx process is locking when I select an FT8 station
6
Ok. I managed to get the WiFi going, which updated the time. Now I'm seeing decodes in the FT8 screen I wasn't seeing before. I ran the update for the firmware on the pi from the HDMI screen. I updated the pico, and it is showing 1.04 firmware for the interface. So now, I'm in FT8, looking at decodes, and followed the example in the "Working FT8" video. I tapped on the decodes with my finger, then turned the encoder, which showed a white outline around the decodes, moving from entry to entry. The problem is, when I choose a decode to work, and press the encoder to grab the callsign and start to work the station, the radio process in the Pi locks up tight. I can't get the process going again without simply rebooting. But this doesn't fix the problem. It only repeats. When I select a decode by tapping, turning the encoder, and pushing the encoder to engage the switch, the radio process locks up. The interface part run by the pico continues just fine, but the waterfall stops, and the signals stop decoding. I can move the selection to another decode, because that's farmed by the pico, but if I press the encoder at that point, nothing happens, because the radio process is still hung. If I have the HDMI output showing on my monitor when I press the encoder, the radio process stops displaying there, too. Unfortunately, while I had a good pointing device to get the WiFi going, that mouse is no longer causing the pointer on the screen to move. I can't try selecting another from the Bluetooth stack, because I can't point to it, and my knowledge of Linux is shaky enough that while I can move the focus from window to window, I don't remember how to bring up the Pi menu or select anything without a mouse. I just need to get a new keyboard/pointing device, so I can fix part of that problem. Just as an aside, I never managed to get that USB-A > microUSB adapter supplied with the unit to work. The dongle I put in that adapter never seemed to be tightly held, and I doubted it was making proper contact. I had a different USB-A > microUSB adapter, which allowed me to access the radio at all. Getting a tad frustrated. I'll probably take a break for a while at this point. 73, Gwen, NG3P

Just received my zbitx. Plugged in the batteries and the unit is hung up with the message: zbitx firmware v1.02 Waiting for zbitx to start... Has any one seen this and how to get the radio working. I can change modes and enter my call sign change parameters. No volume and no signal detected Tom Crowley KT4XN

Zbitx 5v USB Question
2
If the zbitx USB is used to load firmware without voltage applied snd the zbitx powers up to perform that task, is it possible to run the transciever from a 5v USB power pack rather than from the batteries or external 9v supply? Thanks Leo Aniol, AI5II

Why? Why in bitx and ubitx is single balanced (2 diodes) mod/demod instead of double balanced??

zBitx manual
2
As the zBitx have started to be delivered would it be possible to download the manual without owning one unit? This would be useful to help us to decide and order one unit when they will be again available. Other kit providers like QRP-labs allow prospective buyers to download freely their documentation. 73 - Pierre - FK8IH

Power for zBitx
16
Having just received my zBitx, I'm looking for advice on the proper batteries to use in the battery holder. Since the zBitx does not include a battery charging circuit (a good thing, in my opinion), I'm looking for a recommendation for a pair of cells for the attached battery holder (18650? Flat top?) and ideally an included battery charger to charge the two cells. The ability to order them off Amazon is a plus, but not a requirement by any means. Also, Bioenno offers 9v LiFePO4 battery packs in 3 and 6 amp capacities, I assume such a battery would work FB with the zBitx, correct? Here's a link to the 3 amp 9 volt pack and charger I'm looking at: https://www.bioennopower.com/products/9v-3ah-lfp-battery-charger It is not the cheapest option, but it is an option - with a suitable Powerpole to coaxial plug adapter it should be fine, right? (My concern comes from watching Farhan video earlier today and his comment about "always" running the zBitx at 8.2 volts... Thanks, Ken, N2VIP

The challenge - I and many other users want to be able to use a headset for the phone modes in the sbitx e.g. USB headset or a Bluetooth headset. Logically the problem is similar to the routing of audio for the digital modes from the audioinjectorpi sound card to/from the software used for the digital modes. The soundcards identified in the sbitx using the command aplay -l | awk -F \: '/,/{print $2}' | awk '{print $1}' | uniq generates on the sbitx: pi@sbitx:~ $ aplay -l | awk -F \: '/,/{print $2}' | awk '{print $1}' | uniq audioinjectorpi Loopback Loopback_1 Loopback_2 pi@sbitx:~ $ audioinjectorpi (card 0 in ./asoundrc) is the default output (and mic input) for the sbitx analogue audio Loopback,DEV=1 (card 1 in ./asoundrc) is used for software output(Input) to JTDX, WSJT-X or others Loopback_1,DEV=0 (card 2 in ./asoundrc) is used for Software input(Capture) from JTDX, WSJT-X or others Question - is Loopback_2 used by sbitx? If yes, could we use this one to route analogue audio I/O from card 0 (audioinjectorpi) on SBITX to another audio I/O device such as a USB headset or Bluetooth headset? After connecting my USB headset I ran the command again: pi@sbitx:~ $ aplay -l | awk -F \: '/,/{print $2}' | awk '{print $1}' | uniq audioinjectorpi Loopback Loopback_1 Loopback_2 II pi@sbitx:~ $ the II shown in this command output is the USB Headset (Jabra Evolve 30 II in my case) More detail re the ./asoundrc file: The system configuration file is /etc/asound.conf (not exist on sbitx), and the per-user configuration file is ~/.asoundrc. sbitx asoundrc: pi@sbitx:~ $ cat ~/.asoundrc pcm.!default { type asym playback.pcm { type plug slave.pcm "output" } capture.pcm { type plug slave.pcm "input" } } pcm.output { type hw card 0 } ctl.!default { type hw card 0 } pcm.input { type hw card 0 } pi@sbitx:~ $ A couple of references: Advanced Linux Sound Architecture - ArchWiki (archlinux.org) Alsa Opensrc Org - Independent ALSA and linux audio support site These suggest it looks promising, the devil is in the detail I am trying to avoid the use of PulseAudio as that has been replaced in newer distributions using Pipewire and Wireplumber, however both of these sit on top of ALSA. Based on this will focus my efforts on using Alsa if possible to minimise complication. Might not be possible but it is a starting point with help from the references above. Research continues - if I get the answer and tested, it will be added here to begin with and then the wiki page as a Howto If anyone already solved it then please add to the topic. Regards Paul G0KAO

Hi, I have massive problem with my uBITX v5 for Calibrating. When I set the Calibration: eg +10 for the accurate 700 Hz on 14996.000 in USB then press the Mic Button - says calib set. goes back to receive - seems ok. But if I turn the RIG off and on again - the frequency is much lower: eg bay pressing Button 14996.000 - after boot 14664.650 It look like the value is not really set, only temporary in RAM. I had this problems since I have this RIG. Also the Rig is really deaf.. only the most strong stations are received TX - I must on a given QRG go up for abt 300 Hz then is on the QRG for transmitting to the partners QRG I spent hours for resolving this - but no result.... Is there not a point ( Tp on the PCB ) where I can set the Calibration ? Have an Frequency counter/generator here, also other RIGS with are 100% accurancy. -- ** 73 de HB9FIH Erich

zBitx shipping is on the way. We are shipping out about 30 per day. This is mostly due to the slow paperwork at our delivery partner. We are pressuring them to bump us to providing APIs for faster paperwork. We hope it resolves soon. In the meantime, I have uploaded a few videos about the zBitx from my bench. They are in a playlist on https://www.youtube.com/playlist?list=PLm2NDXV2if5C6NdPIbqEXSVMKaZCe36dG Let me know if you have any questions - f

I understand the Z has a built in microphone, however, I prefer a handheld mic. I searched around but can't determine what might be an acceptable mic for the unit. Ideas/insight appreciated. thanks N2KVZ
