I agree with Franco. If what he writes doesn't apply to you, get a G90.

Hi Tony,
I ?ordered the Zbitx just yesterday, despite having read all the reviews and all the problems. This is because I would like an RTX that ?I can get my hands on, in terms of both the ?hardware and the software. I think that this RTX is ideal for people who like to experiment, modify, add things, and learn new way to do radio, like we made in "old days". So, I don't know if it's a safe purchase but I think that if you are used to experimenting, I think it could be a good radio to have fun with.
73, Franco

So, the Zbitiz has been out for a minute.?
Would you all that have the radio say it is safe to buy with no major issues??
Read a few reviews that stated some issues with the unit. I know nothing is perfect obviously.?
I would much prefer to spend $200.00 than $600.00 for the FX-C4R honestly.?

Rafael, I would take a 12 V laptop power supply from a thrift store, and then add a bunch of series 5 or 10 amp silicon diodes until you get the voltage down to about 8 V. Six diodes in series should do the trick
You can probably get the laptop power supply rated for 3 A or so for five or $10 at the thrift store and you can get the diets for less than $10 from Amazon. So you¡¯ll have about $20 into the project.
I hope that helps! Be careful with polarity!

There are some high output (e.g. -28, -30 or -32 dB ) electret cartridges that I've had good success with (and can be found in the WIKI) but a mic that has worked well for me is actually a powered (amplified) CB microphone:
It is $25.? ?You'll either have to build an adapter for its CB plug, or snip that off and replace with a 3.5mm stereo plug (either way works).? ? The CB wiring diagram is straightforward and you can map out which pin goes where on the? tip and ring of the 3.5mm stereo plug.
Listening to the transmissions created by this particular microphone seems to have more energy in the midrange than the electret cartridges and it has a bit higher average power output for the same voice, as a result.? ?Others like the way it sounds when I use it on my sBitx.? ?When listening in on a monitoring receiver, it like it also.
Of course, you could achieve the same outcome by manipulating the source code since it gets mapped into the frequency domain, but just buying the $25 microphone is a lot less work!
Hope this helps!

Thanks all.? The internal seems to be working but pressing a button in my hand will be much easier the fussing with the touch-screen....

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.?

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.

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?
