Re: 60m USB??
NT6S,
Yes, USB under 10MHZ is supported. You just have to go through the menu
and select USB.

Teensy 3.5/3.6 upgrade for uBITX
Here's what our little Skunkworks has been up to.
A wee PC board that accepts a Teensy 3.5 or 3.6 processor, then plugs into the space that would have been occupied by a NANO.

60m USB??
The ubitx looks like a neat project to build for a portable field rig, but before I get one, does anyone know if it is capable of operating on USB below 10MHz? ?I would like to use it on the 60m

Re: uBITX Software error messages

This will likely make no difference, but the error messages that result might. Try creating a directory with this structure:
??? C:\uBITXSoftware\ubitx_20\ubitx_20.ino?? // plus the other 8

Ok Armin.
I count to 9 files under uBITX_20, one of them is uBITX_20.ino. ( the biggest )
I click on it and IDE start up with an sketch file.
I compile and here are the error list:

Carl's case
I just received one of Carl's nifty cases for my ubitx. In addition to speedy service, the case is a winner! Everything fit like it was made for it! Oh, wait, it is made for it.

Re: TDA2228M
Did you mean *TDA2822M*??? That is in the ubitx transceiver (80-10M).? The bitx40 is a totally different radio, but isn't called a microbitx.
If you mean the ubitx transceiver, you can find help

Re: Complaint Department
Could be to the wiki.
But if so, then all 10000 members of this forum could be editing it.
I think a curated errata page on ubitx.net would be preferable for new builders.
But by all means, we can

Re: Micro BitX No Audio TDA2822?
I assume your uBitx arrived with the bad WX TDA2822 part.?
This part:??https://www.mouser.com/ds/2/294/NJM2073_E-275459.pdf
should be a direct pin-for-pin replacement of the TDA2822.
