Shouldn't happen; may happen if the DNS hasn't resolved for your domain but as long as yoursite.com points to 000webhost, is parked correctly, when you change your WordPress URL to HTTP:// yoursite.com then it will be fine.
I use a .tk domain name and not a .com could that have something to do with it?
If you change the settings with WordPress control panel like the image above to your http://hamradiotv.tk on both lines then your site should function fine, if any error occurs post a screenshot if possible and we can solve it from there by logging in and finding out what the issue is.
Look like its working so far
Working fine for me.
Thank you for your check on it for me . Just moved over here yesterday from another free hosting service that kept crashing
