Re: Mic for zBitx

 

I'm working on a adaptor cable(s) from a Kenwood HT Type Microphone to the zbitx, I just received the cable I needed in the mail this week, will try to work on it soon.?

I'm currently working on an adapter for an extra Yaesu MH-31 I have (just for the voice and PTT, not extra buttons)... I think it should work, but I'm not finished yet. Will report back.

Re: Mic for zBitx

 

The input of the zbitx microphone is the same as the input of the sbitx microphone, so I would only use a microphone with an amplifier.
Check out the forum posts about microphones. The description of a handheld microphone and a 'Meeting MIC' covers this.
Since you don't have an original sbitx microphone, there's nothing to modify. That's why go to is the first sentence.

Gary,

You can use any mic that works with any Bitx, currently I use these, ,but I also use the mics that came with all my sBitx's, pretty much all of them work.

Thank you Jody for fixing the iambic keying problem. It works great now. The only errors seen are the ones I myself generate! I am a 70 year old tube radio doctor (licensed as WN1NUU in 1970) and have no knowledge of programming so I am grateful for folks that can fix software issues. You have made the Zbit usable on CW!

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.

Any update on ft8 messenger you mentioned before?

 

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?

Re: zBitx speaker noise? #zbitx

 

Interesting, may try the Drok - my cheapo buck/boosts may just be super noisy.

I don't think a terminating resistor would do the trick if I'm understanding correctly, since the noise comes from the speaker even with headphones in. Obviously they block some of the sound, but it's actually still audible when powered by the buck/boost.

If you are bothered by the noise from the speaker, a solution could be a 3.5mm stereo Jack plug with a resistor as a termination.
It's like plugging in headphones, but instead of the listener, there is a resistor for loading.

Re: ZbitX replacement knob?

 

I'll specify the location of the break: it wasn't the shaft, but the threaded aluminum casting that broke in the neck. I accidentally hit the knob with something.
At the time, I didn't know that it was hard to get a non-click encoder, so I just clipped the connecting legs.
Thinking about the repair in retrospect, it might be possible to repair the break with metal glue. I'll probably try it.

My new zBitX bought at FDIM has no audible noise from the internal speaker but I really like an external powered speaker. I use a Drok voltage/current controller and I hear no noise from that either. Happy camper.?

I think the speaker power amplifier must be really sensitive - the headphones seem immune to a lot of (if not all) the noise, and the speaker can be pretty noisy even at volume zero. I was messing with some buck-boost converters today to see if I can use this with my regular (read: larger) batteries, but they're WAY noisier than the 18650s... in the speaker. Didn't notice a difference on headphones.

Tried adding some toroids to the cable, which helped a tiny bit, but not a ton and it would add a lot of weight.

I'm half tempted to just cut or put a switch on the speaker cable, but I'm interested if there are any cleaner solutions.

Playing around with it a bit tonight - seems that a bit of shielding between the pi and the board may help, especially with some of the noises. I'm getting screen update noise and a periodic crunchy noise, and the latter was most obviously affected.

I just received mine last night, but your video is the same as what mine is doing. I'll have to play around with some shielding of the pi. Thanks!
Re: Sbitx v3 HW_settings.ini gone- how fix?

 

I didn't want to enter this anymore, because we started from the 32-bit hw_settings.ini error.
It takes time for you to process all the new information, but I can still give you something to read? ;-)
For example, there are collections of useful articles in forum-> Wiki or forum -> Files.
Individual writings document the work of many people, the reader often skips over the good stuff because he doesn't need it.
Then they realize that they do need it.

This leads me to two more questions. How do you adjust the settings for the most output efficiency in the hw_settings.ini file, after you have the sBitx up and running on the default hw_settins.ini file?

Now that Bookworm has been implemented with the 64 bit software, will a Rasberry Pi 5 work with the 64 bit software, without any modifications?

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

 

Don't worry, the red line position will not change in FT8 transmission, no matter where you put TX_PITCH.
This thing has been there since the first release. If you have the ability to do it, you can fix it in the program.
The screen resolution is so small that you can only see on an external monitor that you have set your transmit frequency to a blank position.
But don't worry, because this happens to anyone at any time. With a little practice, you will find the solution how to place TX_PITCH.
I also had to do more than a thousand FT8 QSOs, then because of the /p /prefix I moved on to an external wsjt program, which works on an external monitor and I don't have such a problem. (There was another problem, but now everything is fine)
The program had to be rewritten because of the low resolution of the 7" LCD display, but you can't cram the work of many people into a small space. WSJT-x /JTDX vs. sbitx FT8

ps.: zbitx has been miniaturized even further, so there may be additional problems there.
