I did a quick search looking for polarity and can find things on the Battery case but nothing specifying the barrel/tip of the connector for power to the ZbitX.? ?Does any one know what it is.? ?I

Gordon The sBitx performance above was seen with the 64 bit code. A lot of work went into making it work well. Someone will have to repeat that effort or just use the developed code. Also, the Pi 4B

So it looks like the workaround is to just send a dit before you get going; and set the delay long enough so that it holds in. You’re going to have to basically make it hold in for your entire

As a temp solution open the menu after you have landed on your desired frequency and operate with it left open. ?This will keep the screen from refreshing. ?If you’re on ft8 turn the volume

The common consensuses is that the screen writes to the touch display are causing this. There are some that are working on improving this so hang in there and keep your eyes peeled to this group for a

Mine was stuck on MST but there was a hard coded setting in the .profile. ?After I removed that it seems to be working fine.

Lee See the first post for waveform at about 15 wpm with delay 50 and post 117502 for the same speed with delay 600. -- 73 Bob? KD8CGH

zBitx 40 wpm, 150 delay. again looks reasonable except for first dit. -- 73 Bob? KD8CGH

Looks like a drum line - or a bug operator with Great Lakes Swing..............................fortunately, I stay about 20-25, but I can see this as a potential issue.? Lee KX4TT

Thanks Gordon I used the same setup for both the sBitx and the zBitx. Same dummy load, receive antenna, K3, Audacity and Python program. The first excellent results posted in the first post were from

zBitx test rerun at 40 wpm with delay 600. I start recording before sending see the an issue with the first dit in both zBitx 600 delay tests. stats Number of dits 23 Number of spaces 23 Average

zBitx test rerun at 15 wpm with delay 600. stats Number of dits 12 Number of spaces 12 Average Pulse Duration: 0.084414 seconds Standard Deviation of Pulse Durations: 0.011073 seconds Average Space

Bob, with the sBitx we seem to have much better results.? ?Have you tested the sBitx with the same setup? Thanks for your work! Gordon KX4Z

BTW in tests the zBitx delay was the default 50. -- 73 Bob? KD8CGH

I have been working with Mike Johnshoy, KB2ML, on the sBitx 64 bit development. For straight keying I use a test setup of the DUT transmitting at low power into a dummy load with another receiver (K3)

Hey eveyone I have recently received my zBitx and it is making alot of electronic noise either on battery or any other PSU. There is a constant electronic noise then also a periodic pulse. Is this

I used ssh and nano to do the work and commenting out the line in the .profile worked> \\ I think this is a "bug"??

Thanks Juan. I knew this to be the case. ?Tx on higher voltage is fine. ?Rx is the issue. ?As the unit doesn’t use relays for bpf switching I am only assuming that the issue is the higher

Already updated to asia/manila but upon nooting this greets me. Any suggestion for proper updating?
