I kindly ask this community if FLdigi is already installed on my ZBITX that arrived a few days ago and if so, how to activate it

Judging by the traffic on this forum, I assume most of "us" are now working on sBITX and zBITX radios. If any of you have an unbuilt uBITX kit (V3, V4 or V5) that you will never get around to building, please contact me through my QRZ address and let me know what you need to ship it to WV Zip 25704. I would prefer to pay with a USPS money order but I can also do PayPal. Bob WB8BEL

After many QSO's on FT8, I do not see and reporting on pskreporter. I'm I missing some setting?

So I finally was able to chase down enough cables and a micro USB hub to hook up to a HDMI monitor, mouse and keyboard and got it all working along with connection to my laptop over wifi. My question is when I mouse click settings boxes with the remote mouse and monitor, the item high lights, but can't see to be able to change the value like say the drive setting. What am I missing?

I have a question for all you extremely BRIGHT people out there. Watching how the sBitx works, and thinking through how it mathematically computes the single side band modulation, based on a transform of the analog audio input, I am thinking that it is impossible to "splatter" outside the normal bandwidth. That would be highly desirable, because it basically means you don't need ALC (automatic level control) and that you sorta have a "built in compression" if your audio gets louder. Am I right in these thoughts? I've studied the ALC circuitry by putting some debugging print statements in it, and I don't think I've ever seen it do much at all and this was part of what got me thinking that this radio may simply NOT produce splatter. Your input welcomed, 73 Gordon Kx4Z

Hi, If I am running at 9V, and I am transmitting FT8 at 100%, what output power are you expecting and how much power is the device consuming? Cheers, Ben

When working in FT8 on my zBitx I can see the spectrum of the received signal, but I can't check if my TX pitch is at the unused frequency. In sBitx it was shown with the red line on the spectrum. I can see the red line on the spectrum, but its position does not depend on the TX pitch value. Do others have the same problem? Is it a problem with wrong version of the display firmware (i have not upgraded it)? 73, Wojtek - SP5DAA

Is there one place where instructions for swapping to a 64bit pi and installing the V4 are located. I'm an old geezer, but new to this Groups thing, I poked around but only found a lot of fragments to what I was looking for

Could the zBitx display Pico code be modified to show the Raspberry Pi desktop on the internal display?

Ashhar, could you please help with a couple of questions regarding radio ordering status. - Will the latest software updates (e.g. CW improvements) be included on zBitx orders placed now? - Are there any hardware updates anticipated (and if possible, on what schedule)? Thank you. -- Mike WA0YCN

Hi! I’m wondering how to turn the sound off? Thanks! Li KQ4EXQ

I'd like to add a second wifi network so that when at home it connects to the home network but when I'm away it would automatically connect to my phone's hotspot. Looks like tools like nmtui, etc are not installed but perhaps I can add the config manually via the shell interface in a Ssh session and avoid installing more applications that might increase the load. Any ideas on how to do this? TIA, Dino

Hi, So for those that have received their ZbitX in the last week or so..did it arrive with the latest firmware (for both the display and main)? Or did you have to immediately update it? Thanks, Everett-WB9FUW

I am not able to obtain a 'rig control (TX) when setting up QSSTV on the ZbitX (following the released user-guide). I am able to receive signals, just not able to TX. The ZbitX is unable to communicate to the QSSTV app (or vice versa) re: PTT/TX. Any ideas? I have tried 'many' different radios / rig control combinations, but nothing works. (I do have WSJTX running, and of course, FT8). BTW, a small, finned heat-sink plus a small fan seems to have solved any heat issues. Don in Austin N5CID

I was playing around on FT8 yesterday (just got the radio) at 2 watts and was surprised at how hot the radio got and quickly

Hi all, I updated the firmware and software to the latest and Im getting errors in my cli window. any advise? thanks Miguel

Hi there I ordered my ZBITX back in November 2024 when it was launched. Fantastic little thing with a interesting potential. Combining HF with known platform ( Rspberry PI ). Of course, I got my unit as one of the first with high hopes and exiting. So here my findings: * The battery on the side is somewhat interesting move. The battery holder on mine was faulty but I also removed it and are using a regular 9VDC power source. Looks better this way and I do not need to remove the batteries from the holder to recharge them. * Find it odd that there is no proper "shutdown" of the RPI. In my UNIX-book you should not remove power from a UNIX-system. It will potentially break the system. * Having a separate CPU to handle the display from the main system seems to be a compromise as the main RPI cannot handle both from a capacity point of view. That is probably good, but introduces the need separate for FW-updates to both systems. Somewhat cumbersome when needed. * The networkinterfacing using WLAN seems not to be very robust. I find very often (nearly all times) that the interfacing with my DHCP-server does not pick up a IP-address not DNS lookup-information. Meaning that a name resolution cannot be done and the unit is not able to talk to the outside world . Having said that, this is the first node in my LAN that is having this behavior. I have between 20 - 30 nodes that do work flawlessly. * The lack of robust TCP/IP-communication with the outside world has led to that I have not being able to do tries to update the system for many weeks. At one point I hade to rebuild my SD-card from a image given to me. * I find very often that the main RPI is overutilized with a lot of lag introduced when using the radio. So that makes the cumbersome user interface even more unuserfriendly. A more powerful RPI would have been handy to have. * The user interface is far from user friendly. Having to point there and there on the screen to change basically everything is very cumbersome and slow process. The good thing is that there is only one knob to turn. I do not say that the radios of today should have a load of HW-knobs and buttons. The design we have with the zbitx is a bit to minimalistic to my liking. Sorry for this somewhat negative feedback. But I though that I needed to share this feedback to the group. Some issues could be solved in SW. Many cannot be solved due to HW limitations Im afraid. -- Tilman D. Thulesius SM0JZT / Sweden
