zBitx order held by DHL
#zbitx
Anyone else have their order to the US held in East Midlands, UK, with this message? The shipment is being held due to known restrictions at destination and additional processing is required prior to export. If so, what did you have to do to get it released? I'm waiting to hear from DHL whether I need to do anything to get it moving again. I suspect it is something tariff related. Grumble.....

zBitx beeping noise on transmit
I got my zBitx in great shape delivered a few days ago. I am wondering what is causing a beeping noise on my transmitted signal on SSB. I tried both internal and external mics and problem is the same. SWR is great and Battery voltage is 7.6V. I tried using 18650 batteries as well as an external power supply running about same voltage. Any ideas?? 73 de K0NEB

The modified ft8_lib available at https://github.com/gdyuldin/ft8_lib , and it offers a better handling of nonstandard callsigns . However, I wasn't able to simply use it as a replacement of the original ft8_lib sources in the sBitx or zBitx firmwares. It looks like certain non-trivial integration work is needed. Unfortunately, I won't be able to take a look at that before the half of July. Has somebody else succeeded to replace the original ft8_lib in [s/z]Bitx with that improved version? 73, Wojtek SP5DAA

Has anyone used the batteries like on the SbitX that use the XT60 connection. Yes I know its different but they do have adapters or I can make one to change from XT60 to 5.5/2.1. I know the ones I looked at are 7.4V and around 5000ma. Thank you Jim KE0VVu

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

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
