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. Corresponding I/O

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 #ubitx-help
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

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
