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

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

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

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

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

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

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

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.

Got my zbitx and works well with ft8. Can you download fldigi to radio and use fldigi right from the radio just like ft8?

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

Yesterday I have received an email from the German tax office. It appears that my zBitx is stuck in the tax office… Never received something like this request before.
