Same here. Firmware version 1.06. Received my zBitx today, so I might need to upgrade. CW works pretty good BTW, I set delay to 500 and sending 20 ¨C 28WPM is no problem using IAMBIC A.
But SPLIT is not the only problem. If I set VFO A to a frequency in the 40m band (let¡¯s say 7020), and then select VFO B and set it to 7021, when I then switch back to VFO a, it¡¯s at 7015. And when I select VFO B again, it¡¯s also set to 7015. Whatever frequency I select, after toggling the VFO¡¯s they are always back on 7015. Same on 20m but then the VFOs always return to 14076. And split does not work.
?
But, that said, I did not upgrade any firmware yet. And I¡¯m a bit reluctant to do that, because CW works just fine for me, and I don¡¯t know how that will change when I upgrade. I¡¯ve read so many comments on the CW function that I was pleasantly surprised about the keying. For the moment I prefer good keying over a working SPLIT.
