Hi Ashhar, From another post: "I am preparing a new messagijg system that works over ft8 protocol that is different from js8call. It is more like a messenger. It needs the radio to be on, 24x7 (and why not!). That will happen ay the FDIM." Any updates? 73 Wei AG6AQ

Picked up a zBitz at Dayton, I couldn't pass this up. My interest tends more to experimenting, developing and improving than operating, but I do enjoy operating also. My development experience is mostly on embedded systems (flight computers for amateur rockets) where timing is critical and it has to work. The RPi environment is totally new to me so I will be leaning for occasional help from some of the developers here for help in bringing me up to speed if they are willing. Of course I will share all of my trials and tribulations. 73, John N2AFU

I just got notice my order number 4001 is on the way. I am excited to get it in hand and play with it. I ordered it on 04.06/2025, so that's good with all the supply problem they have had. I missed getting to Dayton, but watched the YT video. FT8 messaging sounds very interesting also. Another tool in the tool box to play with. Don KB5KWV

Tony, I just purchased one (a zBitX) at Dayton (FDIM, the QRP Meeting) and have tinkered with it learning everything I can. The bands have been less than stellar but everything seems to work well for me. What fun in a little box for $170 (no shipping if bought at Dayton). If you like to tinker and experiment it looks like a good choice. I would rather have a new thingy to play with (built an Old Friend for 30 meters and a CFT1 on the dining room table in our condo this past winter in Florida -the weather was ucky) so this was an ideal something new to get on the bands with when our club does a POTA adventure. I am always the first to try new things but our club has two more zBitX’s on the way, one by a newbie and one by a more experienced ham. We have lots of fun with QRP and low power here in northwest Michigan. The G90 seems to be a popular item too. I remember when I first moved to this area 53 years ago there was a ham who was rather well heeled and always had the best and newest rigs back when they cost a month’s wages or sometimes more. We had difficulty not drooling on his newest rig. Now it’s easy to have the newest in the QRP field as the size and cost is much different by comparison. And if you want more power the amplifiers aren’t that expensive today. Dave K8WPE

Hi All, I have had my Zbitx for a month or so now. Been using it. Had a few QSOs. Noted the problems others have identified. Choo Choo train noises. and heating. I would like to take apart to add shielding etc. Have taken the front panel off but can't see how to withdraw the 'sandwich'. Rather not resort to 'brute force and ignorance'. Has anyone posted a YouTube video of how to do this or some pictures. Also like to know how to upload FT8 QSOs to PSKreporter & QRZ.com does the zBitx work in a similar way to WSJTX in this respect? If these are seen as silly questions. Please no snark. My request for future revisions for the zBitx to display the IP address it has been assigned somewhere on one of its screens. 73 de 2E0IIY Andrew Wade 6 Elliott Grove BRIXHAM TQ5 8RT 07971 827026

BitXers? Someone have a link for a decent low cost mic for the zBitx? All my mics are Kenwood or Yaesu. They wont work of course. I am assuming any standard 3.5mm plug microphone will work but want to check with the group before I order -- "POWER, WE DON'T NEED NO STICKIN' POWER" - EVERY KX2 OWNER Always respect the airwaves, 73 de KI7PBR, Gary

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

Just got my zBitx today. Powered up, and the nice screen pops right up. It says "Waiting for the zBitx to start..." and no other response. Been waiting a long time, but no joy. Tried power down and restart - same result. Any advice would be appreciated. 73 Dave, VE3WI

I ordered my zBitx on April 3rd, 6 weeks ago. I sent sales an email and got this response "Right now, we expect your order(#3941) to ship by early next week. We ran into some unexpected hiccups with sourcing some components which slowed us down a bit" Fingers crossed I should have mine next week. That will be 7 weeks from order date. Clearing a spot on my work bench to bring it up. Got a road trip in a couple weeks that I hope to have it ready for Excited and anxious, 73 de KI7PBR Gary

I now have my ZbitX and am getting it setup Thank you KE0VVU Jim

Good afternoon, I had a Raspberry TFT screen saved and today I put it on a sBitx computer version DE. But now a problem has appeared, the sBitx does not start and gives the error "snd_mixer_selem_has_capture_switch: Assertion `elem' failed". pi@sbitx:~ $ cd sbitx pi@sbitx:~/sbitx $ ./sbitx sbitx v4.301 Unable to load ~/sbitx/data/hw_settings.ini Loading default_hw_settings.ini instead i2cbb.c:writing address failed at 8 sbitx: simple.c:652: snd_mixer_selem_has_capture_switch: La declaración `elem' no se cumple. Abortado pi@sbitx:~/sbitx $ If I disconnect the power supply from the TFT screen and restart the computer everything works correctly. The Raspberry is a v4, the OS is 64 bits and the sBitt version is 4.3. Any ideas? Thanks, Ramón EA4GZI

When I use my zBitx in FT8 mode with AUTO set to ON, the messages related to finalizing of my QSO (RR73/RRR and 73) are not displayed on the screen (at the end of the scrollable list). I have to open the log (with OPEN) to check if the QSO was successfully completed. However, when I browse the sbitx.db with sqlitebrowser, I can see those messages in the "messages" table. Is this "feature" somehow configurable? 73, Wojtek SP5DAA

Hello to the group-- I'm working on a V6 transceiver and need an AGC board. Anyone have a spare? Thanks -- Rick W7RNB

I'm interested in analyzing the received FT8 messages in a software (e.g., a Python script) to detect messages from DX entities which I'm especially interested in. In case of sBitx, it can be a script running on the radio itself. In case of zBitx it can be a script running on a connected laptop or smartphone. Is such a functionality already supported, or should I patch the software myself? 73, Wojtek SP5DAA

Before I spend any more time building out code modules for the sbitx, I’d like to know - is that product “never to be sold again” or simply delayed? While I enjoy spending days modifying my own radio, I need to know if it’s going to around in the future. VA3CGF

After working with Unix/Linux systems for a lifetime, i know that bad stuff will happen if you just disconnect the power on a regular basis. I still feel a twitch in my fingers if I don’t run sync; sync; sync; before a shutdown or halt command ;) I’ve forked Farhan’s code and added a button on the UI to shut down the Pi Zero: https://github.com/khkremer/zbitx.git https://github.com/khkremer/zbitxfrontpanel.git The "Shutdown" function is behind the "Menu" button. After selecting it and confirming, wait until the LED on the Pi Zero (which you can see through the covered USB connector) stop to blink. I moved the confirmation button a bit up so that it’s harder to fat finger the shutdown with an unintentional double tap on the shutdown button. de Karl Heinz - K5KHK

I and a few friends just got back from Four Days In May with our new zBitx xcvrs. The manual recommends using a monitor and keyboard for setting up time and some other features but I don't have those available. Could members of this email site recommend a small key board and monitor and advise on a size for each. I want it to be portable to take when we go to Florida next winter. Amazon and eBay are fine sources. Dave K8WPE. Djwilcox01 at Gmail dot com PS to Jim (past CARC Club President) Jim, I know you used similar items when active with your small portable rigs. What say you?
