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

uBitX V6 --> adding separate fuse for finals.
3
Hello, Last time I used my uBitx the magic smoke was released. The radio was idling, just listening to something (probably FT8) when I noticed a glow in the room and pulled the plug. It looks like I may have just burnt the trace nearest the edge on the underside, which I think is the main power rail to the switch/pot. I repaired this today and the unit powers on, but I won't test it properly until it is back in the case with everything connected properly. On here Fix: Reverse polarity – uBitx there is mention of connecting separate fuses for the main board and the finals, using the P1 header. My brain gets confused by schematics which have breakouts, so I do not understand how P1 is connected: the article suggests that 3 connects to ground (correct) and that 1 and 2 connect to the main board power rail and the finals rail (not sure which is which). My DVM probing is showing the schematic's suggestion that 1 and 2 are connected rather than being separate. So, my question to anyone who has performed this addition, or is better understanding of the schematic, is whether I should disconnect the center pin of the barrel connector and connect two wires running to the two fuses, then respectively connected to pins 1 and 2 on P1, or whether I should be tapping a trace elsewhere for the finals, or just run two fuses in series (!?). Or just a single 3A (or 5A) fuse. When I had my magic smoke episode I did have a 5A fuse, but it may have been one of questionable origin in the power distribution block. I have subsequently replaced all my fuses with Littlefuse things, since they do seem to burn when they should. Thank you, KK7BCO
