Russell, Check your power supply (or batteries if using). Two of us from our club bought the zBitX at FDIM and bought batteries in the flea market. After about 15 minutes of just listening the screen

I remembered wrong because it was in the 3v3 circuit and the values ??were 47uH and 22uF. -- Gyula HA3HZ

Steve, I remember that it is possible to isolate individual circuits from the power supply with a series inductor and an electrolytic capacitor. It would be worth trying if you are already so deep

On its predecessor, the sBitx, the codec would occasionally go out to lunch (usually on startup) and then you get zilch nada nothing. There have been various improvements in the I2C connections, but

I received my new ZBitx last week and pulled it out for an initial operation today. Mostly checking out FT8, recriving signals and had answered a couple when suddenly the receiver started putting out

Thanks Gordon - I do remember all the work you did to reduce the spurs on your SBitx. Your comments did remind me of something I tried - In it's stock configuration, Q3 gets its power from the same 9

Here is a post where I summarize some of the work I did to clean up my (secondhand ) sbitx: Re: sBitx spurious emissions groups.io Gordon kx4z

Steve, that is really admirable work!! Without this kind of investigation, I’m not quite understanding how this project proceeds. I remember spending weeks and months trying to figure out Spurs in

I got my ZBitx earlier this week, and put it on the test bench to check it out. My setup is a Rigol DSA815 1.5 GHz spectrum analyzer, along with a newly build coupler with a -40 dB tap. Here's what

Thanks all! I’m not worried about simple issues. I don’t CW. My use is voice and I want to try digital My big issue is I’m sort of a nomad right now. I rent a small apt and work 2 jobs, (trying

Gents, Thanks for the info! I thought the review was great, BTW Dave! I look forward to fiddling around with this radio and honestly, weight isn’t a huge issue for me as I am loading my e-bike down

Yep. Putting the gps module inside is the best solution for portability. If there is no way to cram it in as-is, most of the case is 3D printed and with the stl files, it shouldn't be too difficult to

It DOES go below 9V. I missed that at first!

I have been wondering the same. *This (

Joe and Jody, thanks for the additional details on your set ups and usage.? I was all excited to have gotten four hours out of it this morning before wlan0 crashed.? Rebooted and got five minutes

I have wondered if putting one of these in the radio tied directly to the pi. I use this on a raspberry pi pico (no wifi) for a WSPR TX. They are tiny. I would think there is room in the zbitx(now I

Still on a steep learning curve with this remarkable radio I got at FDIM in Dayton and had my first SSB QSO with a good audio report using the built in mic and awkward touch screen TX/RX buttons. I

The zBitx display stops responding to the mouse scroll wheel or keyboard up/down keys after a few clicks. Jim N7IHQ

I have the same problem with the scroll wheel on my mouse. The values changes intermittently. It works ok on OS windows. Jim N7IHQ

Here's the keyboard/trackball I plan to use: https://www.amazon.com/dp/B094VVL7Q9 I got this one because the keyboard isn't quite as tiny as the one I'm currently using. It's really for two thumbs,
