There is a 17m activity group on 18.157.50 almost everyday (mid-day). Usually organized by w6ff out in Ca. Through that group I have worked from Hi to SE Caribbean area. I could hear Ca. talking to Australia and New Zealand. but my 100 watts and a dipole couldn't quite make the trip. Better propagation is coming. I have acquaintances that work FT8 there with good success. Other than CW my HF equipment has no digital capabilities at this time.
As mentioned in a previous post, when there is a major contest going on, 17 is my refuge from the confusion and noise.
