Re: Practical CW Operation? #ubitxcw
The uBitx works well enough as a CW rig out of the box if you have clean enough key contacts.toggle quoted messageShow quoted text
Here's an old post regarding possible enhancements:
The stock uBitx firmware uses an ADC channel to listen to a straight key and two keyer paddle contacts
all over one wire, distinguishing between the three by a resistor network that gives each a different voltage.
That's been a bit problematic if the key or paddle has any dirt on the contacts, I'd recommend upgrading
the Raduino firmware to something else. The firmware could use the PTT digital pin when in CW mode
as a straight key input.

Ehhh! Listening to cw with a 2.someKHz filter is good for you! It will hone your cw listening skills and let you learn to pick the right signal out :-)
