Create another Steemit Account

Today I tried to create a second Steemit Account. I thought it could be my amateur radio callsign and make that blog's sole purpose documenting my amateur radio experience and thoughts. However, it required having a different email address and phone number to the ones used with this account. Unfortunately, this is currently not possible for me.

I wonder if there is another way to create a secondary account for free. If anyone knows, that would be much appreciated. Otherwise, I shall keep searching the internet.
