Why? Why in bitx and ubitx is single balanced (2 diodes) mod/demod instead of double balanced??
Why in bitx and ubitx is single balanced (2 diodes) mod/demod instead of double balanced?? Just cost?

What's the downside of running the zBitx from a slightly lower voltage?
I have a few LiFePO4 18650 flat tops I got from batteryspace.com. I prefer that chemistry for its lesser fire hazard. LiFePO4 cells only charge up to 3.65V, and run down to around 3.2V. So a pair would only provide somewhere between 6.4 to 7.3V. Me too. So now I have to decide whether it’s better to use them in the simple battery holder, or use the alternative battery holder that I also got, that steps it up to 9V and has a USB-C charger. I guess with 9V I’d get a little more output power, and maybe have to worry about cooling a bit more? But it won’t cause any damage?

Re: SBITX v3 - Ability to use a Headset for phone modes
Don't stick to a headset with a famous brand name, they usually don't work for this purpose.
I decided to buy a good working headset that has worked well for others. It's true that its name doesn't appear in alsamixer, and all the switches and sliders work fine.
Thanks to JJ for that, which he wrote in message? #109910?? ?. Yes, the important thing is that there should be no error messages. --

It will run all the way down to 5.5v, the output will be much lower, though

Glad the Settings Editor helped you!
?
My recommendation is to write down your calibration settings and reinstall CEC 1.2. My V2.0 (beta) was primarily targeted at supporting more modern MCU's (e.g. teensy, pico, etc.)As such, the size of the software increased slightly to achieve the goals of 32 bit and portability. Consequently, some "standard" options that are available under CEC 1.2 (primarily WSPR, but some other settings that you would normally get to in "console" mode too), were disabled on Nano's to fit the software. After re-installing 1.2, you can transfer the calibration settings if they do not come across.
?
There is no increase in functionality for 2.0 vs 1.2 for Nano users. ?That is the reason for my recommendation.

Re: zbitx hung-up on startup
Mine, as received yesterday does the same.? There is a small weak buzz in the speaker about every 5 sec as well.? See attached screenshot.?

?Please? avoid sending? me? Word? or? PowerPoint? attachments.
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? - ff

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"?

As said above mine is 20-30 seconds.??
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?

Takes 30" to boot with V1.04.

Charu,
You can use the standard sbitx image and replace the sbitx sources with those from the zbitx repo. The git gurus can do this in a single line, I am told

You have one uploaded for sBITX.

Gwen, I'm not sure if you have updated your zBitx to the latest software and firmware. To do a firmware update, you will need to follow the procedure mentioned by Farhan in this post. To update the software, you will need to connect the zBitx to an external display, keyboard and mouse, and use the terminal program to run "cd sbitx" (if you're not on the sBitx directory) followed by "./update" to update the software.? ?
You can refer to the Farhan has shared on YouTube for reference.

Hope this helps.

All,

Note that posting to this thread will not put you on a list to be notified when the zBITX ordering is open.? ?There will be a post for the group when orders are accepted.? See this post:

You can send an email to HFSignals to get a private notification.

Re: Zbitx external microphone recommendations
If you are looking for a solution thats POTA/SOTA friendly, you can try either one of these three options:
1. 3d print a portable microphone such as
2. Buy a cheap microphone (like cheap baofeng microphones) from amazon, snip the exisitng connector and solder a 3.5mm TRS stereo connector.
3. Go for a DIY solution such as the ones seen .?
?
The wiring is similar to the uBitx and sBitx radios. The PTT switch connects to ring and sleeve. The microphone connects to tip and sleeve.?

Neil,
The connectors are (from left to right):
1. Type C USB for powering the Raspberry Pi
2 & 3. Micro HDMI ports for connecting HDMI displays/Monitors/TV. There are two ports for dual displays
4. 3.5mm TRRS audio jack used to output the audio from the Pi.

Those are the connectors directly on a pi4. ?Usb c is power only to the pi, ?other 2 are hdmi outputs and the last is the pi 4 audio jack. ?You can look up documentation on a pi 4 for more information.
