Finding variables in source code
I remember GREP from the old DOS days. Most editors for programming have a search feature. One could also load the code into a text editor and use its search function. Virus-free. www.avast.com

Removing insulation from fine wires
In a pinch, I have used my lighter. Quickly heat the area you want the strip to start at and then grip the wire firmly and give the insulation a pull. Kids...don't try this at home.

Google "oop and microcontrollers" or "C++ and microcontrollers" . The main reason is the code bloat OOP generates

Compiler warnings
C++ and micro-controllers do not really play well together. That is why I use strictly ANSI C.

Running on a Jump Box
The unit is going to draw (amperage wise) what it needs. You should not limit it. Now VOLTAGE is a different story, you will want to set that between 12 to 13.8Vdc. As stated use RV1 to adjust the out

Teensy I2c on wire2 (SDA2/SCL2)
#ubitx
Haven't tried it, but remember that the si part is running at 3v and the display is at 5v. Therfore you will need to use 4.7k resistors to pull the SDA and SCL lines to 3v (NOT 5v). Make sure you remo

SWR
The on-board A/D has 10-bit resolution (0-1024). If you use a precision 5V external ref, that comes out to be 0.0048828125 volts per bit. If you use the internal 1.1v ref, it works out to be 0.0010742

I agree the I2C would be a lot slower. You are better off using the ADC inputs directly and let it "free-run" (I use ADC6 and ADC7). That way when you need to access the data, it's just a quick check

Please don't make Radiuno with CH340/CH341 chipsets any more! Or at least advertise that you do use them!

Interesting. You guys(Apple users) always said the Apple was "bullet-proof". I guess there IS a way to "hack attack" an Apple! I'll stick with my PC. Glad you found a "fix" though..... Virus-free. www

show your mic
I simply replaced the element in an old replacement stock CB mike I had with the one supplied in the BitX40 kit. Works quite well.

Transmitter Mods
I heard that some guys are switching in/out bias control pots for each band and adjusting them to maintain the same power on all bands.

UbitX I2C GPIO Breakouts?
Good idea Nick. On the Atmel, max I2C speed is 400Khz, but a lot of devices do not like this "hi-speed" and you need to run them slower. Right now I have my bus running at 200Khz and see no delay on m

UbitX I2C GPIO Breakouts?
I managed to get a few free samples of the PCF8574N from TI. It is an I/O expander I2C - 8bits in a 16DIP package. It is basically the chip used on the I2C LCD piggyback boards. I keep you posted.
