I didn't know that. Since all of the Nano pins, including the analog pins, can be used as digital pins, I thought they, too, would have pullups that could be turned on. Is that not the case?

The INPUT_PULLUP pin qualifier activates the internal pullup resistors and should produce enough voltage to read logic HIGH on the pin. A closure of a switch (or key) on that pin will pull it to GND, which is probably what is wanted. Given the voltage divider circuit Ashhar uses for keying, the pin qualifier may not be what he wants.

Re: Different Tuning Steps
#ubitx
You'd have to change it in the source code and then compile & load it. I don't think Ian has released the latest source. And it might be (most likely is) more complex than just changing the data type on the variable...depends on how the code is written.

Re: Finding variables in source code
I think we all run into situations where we need to find the definition of a variable or object in a large set of files. The UNIX tool Grep is perfect for doing that. The Grep version I use is not longer available, but I just downloaded and tried this version and it seems to work well:
If you want to change the data type of a variable, use Grep and type in the variable name, supply a search path, and BINGO it finds all occurrences of that string in the directory/subdirectories seach.

Re: Windows Serial Port Problem
The uBitx uses a clone nano and the serial/USB chipset CH340.
In Windoze 10, open Device manager and right click the unusable/unwanted Parallel port LPT3 and delete it.
Download the CH340 USB serial driver and run it.
Plug in the ubitx and Windoze should install the correct driver.
If it still doesn't work, maybe try editing the Windoze registry and remove all com ports...
A reboot may help (it's Windoze after all).

Re: Different Tuning Steps

Try something under the maximum value 50000 should work and be almost as good as a fast way of getting around?
i presume you ?know about Gen Coverage mode?? Go to band change and hold down the switch for a couple of secs.? It will then step up and down by a MHz on band change, which may also get you where you want to go?

Yes, it is KC8CEC 1.08.?? Changing those values does change my step size but the 100000 displays funny while setting it or using it.
