Re: zbitx hung-up on startup
Mine is hung but will not power up off batteries. ?See the video. ?All the ports are not standard.?

Tilman, tnx , I 'll update the RPI, I've already update the front panel.

I have also been a CW op for 40+ years and am unable to send anything accurately with the built in keyer. Will try with an external keyer later today.?

Re: Zbitx external microphone recommendations
Interesting point, and probably relates to why there is a momentary transmit activation of the radio when plugging in a microphone. Gordon KX4Z
Hi there
I find it odd that the pinout of the microphone is different from all other radios having 3.5mm stereo connector.?
They "all" do have PTT to tip and ground and microphone to ring and ground. Means that I would need a adaptor to connect up my microphones? :-(

Hello Ashhar
?
I've received my zBITX this morning and have been listening on the bands in different modes. So far all seems to work as expected and it is fun to use this little rig.
But I'm lost by trying to send CW with the built in keyer. I'm not used to Lambic A after using Lambic B for 40+ years. When set to Lambic B you get a straight key. Is Lambic B not yet implemented or have I set something wrong? If not, will this be included in a firmware update?
Taking an additional external electronic with Lambic B keying half the size of the zBITX for portable use was not my plan...
?
Many thanks for this otherwise nice rig and for any info

Re: ZBitx hangs on startup
The image didnt come through. Can you mail it to be directly?

Pierre,
The manual should be up on the site soon. We're working on revising it to make sure we document all the features on the zBitx.
Meanwhile, please have a look at from Farhan where he documents the functions of the radio.?

Re: Why? Why in bitx and ubitx is single balanced (2 diodes) mod/demod instead of double balanced??
It was just because, in a modulator, we didnt need to balance out the audio. The audio automatically gets filtered out by the crystal filter
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"?
