My Sbitx is in breakin mode on CW
2
Hi to the group, I am new to the Sbitx and was following thee directions to check for updates and i got an 'fatal error' No such file or directory, #include oled.h When I rebooted the radio it now has no delay in CW relay click and clatter and no delay. Again it appears to be breakin mode. Not sure what to do to fix it. I may need to reload the software, if that is the case -- what are the commands to do that? Thanks in advance -- Rick W7RNB

zBitx Buster upgrade error
4
I tried to upgrade the original Buster 32-bit distribution using sudo apt upgrade. After rebooting I get the error message: sbitx: simple.c:649: snd_mixer_selem_has_capture_switch: Assertion 'elem' failed Is the original distribution image available on the web to reprogram the SD card? Can the zBitx software be compiled for a standard Raspberry OS distribution? Thanks, Jim N7IHQ

Folks, I bought the radio kit, built it and I don't believe I was ever able to transmit. I have another radio and I can receive on the ubitx but nothing I do makes a transmission. I bought a crummy baofung microphone and cut off the speaker connector. From what I could tell the 3.5 connector is supposed to be wired correctly for the ubitx. When I plug the mic in the red light on the mic is on. When I push to talk the red light goes out and the TX lights up onthe display. However, I do not hear anything on my other radio. Is there something simple I am missing. It has been ages since I looked at this thing and now I am somewhat regretting it again. It has been nothing but a headache. But I thought I would give it a try again. Thanks for any help you might be able to provide. Andrew

zBitx disassembling guide?
5
For sBitx v3 there is a nice disassembling guide: http://www.sbitx.net/index.php/2025/01/24/disassembling-the-v3/ Is there a similar documentation for zBitx? 73, Wojtek SP5DAA

zBitx - Loud Audio on FT8 Transmit
3
#ft8
#zbitx
I have the same issue. It appears it's a timing issue. In that, the RX audio is not fully muted before the tx is activated and we get a partial audio feedback. I am assuming your not referring to the actual tx audio, as that is controlled in the SET button. Joe VE1BWV

Zbitx at 12vdc
11
I would like to run my zbitx at 12vdc and up to 14vdc. I already swapped the linear regulator and the finals and re biased. It works great up to about 10vdc over that the receiver starts to attenuate. I am assuming this is because of the switching design for the bpf. I remember Farhan mentioning that there were components that could be swapped to allow for running up at 12vdc. Is it possible to get a rough list as to what these components are? Ryan KK6DZB

Has anyone had success using the QSSTV program which is installed on the Zbitx? I tried many options available for the Sound but none worked. I cannot see any action on the rx waterfall, even when I see it on another rig. Thanks Joe VE1BWV

Has someone of you tried a distribution upgrade from Buster (Debian 10) to Bullseye (Debian 11) already? Or one brave one done a reinstall complete new to Debian 12 Bookworm 64 bit? Please let me know your results or share your hints to be successfull. 73, Michael

I have a minor update to make zbitx work with wsjtx/fldigi/etc and fixed cw latency. You have to update just the raspberry zero. From a terminal window, type this: cd ~/sbitx ./update sbitx this should do it

No output power SOLVED

zBitx's no power issue fixed. Thanks to HF Signal's support, a problem with the SD card contents was detected. Just reflashing it was enough to bring the zBitx back to life. Thanks everyone! Raul EA3HLF

Where is the line at for ZbitX's that are shipping.

Where are they at with the order numbers on shipping the ZbitX's. I might need to be out of town and need to make allowances to have someone get my package for me. Thank you Jim KE0VVU

Is there an option on Amazon for a handheld mic for the zbitx? Or perhaps another online retail outlet?

QSSTV on ZbitX
2
I am not able to obtain a 'rig control (TX) when setting up QSSTV on the ZbitX (following the released user-guide). I am able to receive signals, just not able to TX. The ZbitX is unable to communicate to the QSSTV app (or vice versa) re: PTT/TX. Any ideas? I have tried 'many' different radios / rig control combinations, but nothing works. (I do have WSJTX running, and of course, FT8). BTW, a small, finned heat-sink plus a small fan seems to have solved any heat issues. Don in Austin N5CID

No output power
16
Hi all I've just received my Zbitx and plugged in for the first time, all seems to be working, I'm only using ssb, but when I touch the transmit it shows the screen but NO output shows and the swr remains at 0, so I don't think anything is getting out. I'm using an EFHW that the swr on my main rig shows about 1.2 - 1.5 . Do I have to set the internal mic on somewhere? I don't have an external mic yet so I'm using the internal one. Can anyone help please Martin G7UGB

Web Interface Band Selection Buttons
4
#zbitx
Hello, At the web interface at the first row there are placed the band select buttons. Here I can see at the 10m Button under the 10M text the number 4. Funny thing is that this is only at the 10m Band button. When I added a 60m button => means one more Band Button at this row, the digit 4 disapears from 10m button and is now at the 12m button visible. Anyone else with this "digit 4" at 10m Band button? 73 Michael

Microphone query

Can I just plug a general microphone with a mono 3.5 plug (and no switch) into the mic socket and use the on screen transmit/receive buttons or does it have to be configured with a ppt switch.

Zbitx Musings
5
Hi, Taken the covers off my Zbitx, and just trying to work my way around the PCB. In the circuits available which are possibly out of date, it shows LC matching on either side of the 40 MHz crystal filter. Looking at the board it appears to have one L matching inductor T30-6 with 13t (one is a wire link, but the 22pF capacitor appears to be still fitted) Please could someone confirm whether that is correct. Thanks Kevin
