Re: Practical CW Operation? #ubitxcw

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 :-) 

In all seriousness, Gordon’s suggestion of an audio filter is a good one. While it’s not really the same as a filter in the receiver, they’re pretty good…or can be…and certainly can be very effective. I reckon that a DSP-based filter would be a bit beyond the capability of the Arduino. Also probably not exactly cost effective as compared to the rest of the radio. 

Do remember this is a really low-cost radio, and you probably won’t get Icom performance, or probably not even Xiegu performance, out of it, though I’m sure what you will get will be pretty decent…especially given how popular the rig seems to be.

Just add an audio filter to achieve whatever bandwidth you prefer would be my suggestion

I've heard that the ubitx doesn't work very well for CW due to being too wide in the receiving end. How are some of you correcting this? Particularly, how can someone who can handle a soldering iron but is not an electronics whiz, adapt the ubitx for practical CW operation?
Thanks and 73
