Would be interesting to try a high side BFO with your Teensy, see if it has any issue with battling oscillators: ? ??/g/BITX20/topic/14533495

Yes, below 10mhz on USB works fine, USB can be selected within the menu system, Could easily write firmware for the Arduino Nano to channelize as per US usage and select USB automatically, whenever a

Forgot the photo,,,

NT6S, Yes, USB under 10MHZ is supported. You just have to go through the menu and select USB. Marco - KG5PRT

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

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

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: Arduino:1.8.5

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. This is an elegant

Did you adjust the BFO? They come way off frequency with audio as you describe. Press the rotary encoder button and select Settings. Press again when display reverts l and select BFO calibrate in

Here's a schematic:??http://www.hfsignals.com/wp-content/uploads/2017/12/ubitxr3.png You might try adjusting the BFO within the menus. See step 3, "Setting the

I WAS GIVEN A MICROBITX WITH A BLOWN UP TDA2228M CHIP, I REAPLACED IT AND NOW THE AUDIO IS VERY LOW. IS THERE ANYPLACE ELSE THAT I SHOULD BE LOOKING TO FIND OUT WHY I HAVE LOW AUDIO? ALSO THERE IS A

Here's an old thread on it: ? ??/g/BITX20/message/40038 Here's a summary: The uBitx 11.9965mhz BFO can have harmonics that can beat with harmonics of the 16mhz oscillator on the

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

Hi! Farhan already knows this story of mine regarding 2822's. Recently I made a simple? low noise receiver. Seeing the specs and after a nice discussion with Farhan I used this chip. Bought 10 pcs

Sorry about that I thought you were asking for the BITX40 schematic. I don't have a copy of the ubitx. Dale

Finally got the notice that my uBITX has been shipped to India Post.? Ordered it 1/20/18 and received notice 3/13/18.? It would appear that they are catching up a little as I expected about a 45+
