Hi John, no not yet. Plan is do that asap, duplicate the final stage with RD16HHF1's and hook up to my driver section.. Depending on how it all works of course, then mod my uBITX. glenn

Bob GM4CID placed a comment on my article“Ubitx modders are hard at work” <http://ubitx.net/2018/03/11/ubitx-modders-are-hard-at-work/>? about another very interesting Raduino solution from

Bill ... 13.8VDC would be the absolute max for the main boards ( BITX40 and uBITX). I would suspect this level is stressing the raduino, relay coils etc. over time, and stuffing the gear in an

How about the Q90 collector? If it's 12v, then Q90 is probably blown, though look over R81. If it's not 12v, then R84 or T8 are bad.

Jerry,? Following your suggestions I started running some tests on my uBitX.? You asked whether it was plugged into an antenna. Funny you should ask that because I had just plugged it into a brand

Wa 1. Software - you do need to compile it and upload to the atmega micro controller. There are several tutorials available. It sounds more difficult than it actually is. 2. Hardware - On ubitx.net

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
