zBitx power supply
Could anyone recommend an affordable power supply I can use with the zBitx, to use with 110 or 220 VAC, 50Hz and 60Hz? Cheers, Rafael

Mic for zBitx
7
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

After letting my zBITX sit unattended in Receive Mode for a while, the main RasPi CPU crashes. I have never timed it because I'm not just sitting there watching it. But it seems like it only takes about an hour or so to crash. I am not able to get a SSH connection to the main CPU at that time. The display CPU is still running at that time. While the device is warm whenever this occurs, I do not think that it is a thermal issue because if I disconnect and reconnect the power it reboots and runs fine. I have never stopped the sbitx application to see if something else on the RasPi could be causing it. I have SSH and VNC enabled, but I am not using either of those connections. I do not have anything else running on the RasPi. So, I really do not think that it is some other RasPi appllication. I think that it is probably a sbitx application memory leak. Don't see how something like a character array overflow would occur after just sitting there unattended for that period - nothing is being done on the GUI during that time. This crashing occurred whenever I had version 3.021 installed, And it is still occurring with version 3.052 installed. If you are running on batteries, the batteries may be depleted before this crash occurs. You will never see it. I am using a 7.5vdc power supply. 72, Jody - K3JZD

Physical Disassembly ZbitX
2
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

Any update on ft8 messenger you mentioned before?
2
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

zBitx speaker noise?
14
#zbitx
I hear a pulsing noise from my zBitx speaker, even with a dummy load connected instead of an antenna, and both the audio volume and IF gain turn down. Seems to pulse or hum 3 to 5 times per second. Is this normal? Or an issue that needs to be fixed? Anyone else hear this from their unit? If it¡¯s a problem with my unit, any ideas on where I should I look to diagnose and solve this noise issue? 73, Ron

Hi, I am looking for a nice metal replacement knob for the ZbitX. Would be nice if it had a tuning dimple or knurled edges. Prefer a vendor on eBay, Amazon, or Mousser or someone in US. Has anyone replaced theirs? Regards, Everett-WB9FUW

Hello All, well I did it this time. I was trying to make a backup of my Sbitx software and I had a usb stick it one port, on my laptop, and an SD Card in another port. When it came for the backup the imager program asked me if drive F, so I thought, was ready for formatting, of course I said yes and I soon found out it was drive E instead of F. Well anyway I deleted my only copy of my Sbitx software for my Sbitx v3. My question is how do I make another HW_settings.ini file. Do I do some type of calibration? I heard that you don¡¯t calibrate the Sbitx v3 the same way you calibrate a Sbitx v2, so I¡¯m stuck. Also I¡¯m moving over to the 64 bit version of the software. Do you still use the same HW_Settings.ini file for the 64 bit versions software? I did a search over the past postings ani I couldn¡¯t I find a definitive answer to my problem. HELP!! thanks for all the participation in advance. All thoughts welcome. Thanks again, 73, Robert, AG6LK

zBitx - TX pitch in FT8 not shown on the displayed spectrum
4
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

zBitx doesn't start up
5
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

Update On Shipping Delays from HF Signals
9
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

Error starting sBitx v4.3 64 bits
10
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 declaraci¨®n `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, Ram¨®n EA4GZI

zBitx - final messages from my QSO are not shown on the screen
2
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

sBitx or zBitx: Analyzing the FT8 messages in my application
2
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

sBitx v4
9
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

ZBitx Shutdown Function
13
#zbitx
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
