As the zBitx have started to be delivered would it be possible to download the manual without owning one unit? This would be useful to help us to decide and order one unit when they will be again available. Other kit providers like QRP-labs allow prospective buyers to download freely their documentation.

Zbitx external microphone recommendations
What seems to be the most practical external microphone for the Zbitx? Thinking about one for POTA or SOTA.

Hey Farhan, what would be the best way to report bugs, on the groups or over on the zbitx github?

Re: zbitx hung-up on startup
Tom, It shows the tubes only on the HDMI screen. Does the software run on the HDMI screen? If it doesn't run, then there will be a black terminal window (on the HDMI screen) with?some error message. Do you get any? - f On Thu, Mar 27, 2025 at 9:04?AM Tom Crowley KT4XN 1738 via <crowleytj= [email protected]> wrote:

What does it show on the screen? Can you send us a screenshot of your HDMI screen about 30 seconds after it displays the "tubes"?

Have you restarted the radio.?
If that doesn't work.? Try to connect to a monitor via the HDMI cable and connect to the wife and do the updates?

Re: zBitX radio hanging randomly.
Gwen, you should upgrade the firmware on the pico as well as the software on the raspberry pi? Here is how you do it: First, do this? Then, this?
Thanks, David. I think I understood all that. I'll try it tomorrow.?

What are these connectors - both what kind of connector (one I believe is USB-C) and purpose?

Re: zBitX radio hanging randomly.
Ok. I may have one of those keyboard/trackpad combos somewhere. If I don't, I'll get one. I think I was confusing the method for sending the updated display firmware to the pico with connecting a keyboard/pointing device to facilitate getting the time up. I just hope I have an open HDMI connector on my monitor. I know where I have the cable. Might need a displayport -> HDMI cable. I had to juggle my ports on my monitor recently.

Re: zBitX radio hanging randomly.
If you have a keyboard with a mouse pad on it, you connect the usb connector(from the keyboard) into the OTG dongle into the zbitx. If you
don't have a keyboard with the mouse, you may need to use a usb hub to be able to connect the keyboard and mouse, to the OTG. Once thats setup you can control what you see on the monitor.?
|
Re: zBitX radio hanging randomly.
I'm confused. You use the OTG dongle and? microUSB to the CAT for a keyboard and mouse? Wouldn't you use a USB-C cable to connect a keyboard and mouse, or do those only go to the Pico running the screen? Also, if I use the OTG dongle, I'll have a cable with microUSB on each end. I don't know that there's anywhere on my computer I can connect that. Again, foggy brain, tomorrow. Then we can sort that out. Hopefully. Sigh...

?D'oh. Looks like I was imagining things when I thought the barrel was smaller. Turns out it's 5.5x2.5, or 5.5x2.1, whichever is usual. Because that's what I got a bunch of pigtails for, and put PowerPoles on them for a bunch of other 12v radios. So that's ok. I've got one with an XT30 on it for connecting to the DC out jack on my Omnicharge Ultimate power bank. You can specify the voltage and amperage on that connector without resorting to PD. It HAS PD on it, but those are USB-C connectors. XT30 and XT60 are popular in drone battery power, the connector used on the SBitX. I have two battery boxes with LiFePO4 12v batteries in them. I got one from HRO, and I think the battery is 7Ah, and the one I bought is a 12Ah battery. I used PowerPoles for that output as well. I have a PowerPole to XT60 for the sBitX, to connect it to one of my more usual 12v battery boxes. The Omnicharge doesn't have PowerPoles, so I'll use the smaller XT30 for that. I'll have to put a flag on the cable to only use it for the zBitX at 9V.?

I had a couple of flat-top 18650s all charged up and waiting. They work very nicely.

I ordered a PD USB-C -> 9V tonight. But I ordered it with the fairly standard 5.5x2.5 barrel plug. Not realizing the zBitX used a WAY smaller barrel. What IS that size, anyway? I'll see if I have an adapter, as I don't think I can get a PD cable with it. Maybe. But I'll need the size and polarity of the barrel to even try. (Heck, I need the polarity of the barrel anyway, in case the cable I ordered is wrong!)
?
I'm also having problems transmitting. Set to IAMBIC, which I assume is A, but I find out after I've been a ham for over 25 years that it's only relevant to SQUEEZE keying. But IAMBIC is working very badly (and IAMBICB is WORSE). I'm usually better at keying a paddle, but it's throwing in random dits and dahs in elements...I have to run really slow to get it to come out correct. It's very similar to trying to key a rig listening to the sidetone in a Bluetooth headset, with all that latency. Is there latency that needs to be adjusted in the paddle on the zBitX? Is that the key delay setting in the SET menu for CW? I couldn't fathom what those settings were FOR. Please Ashhar, explain me!
