What frequency?  Do you see other signals on a waterfall?

Check out the K1USN SST (Slow Speed conTest) Fridays at 20:00Z and Monday 0000z (Sunday night US time)--see http://www.k1usn.com/sst.html  

CW is normally at the low end of bands (7.000-7.050, 14.000-14.050, etc).   

There are many CW resources available--see CWOPS https://cwops.org/cw-academy/

Good luck.
